GNS3 WorkBench 8.6 8.7 is out The next version of GNS3 WorkBench is out. You can it several forms: • An entire Virtual Machine as a single blob (although split into two files 2.5G-3G in size) • The same Virtual Machine as individual files (in case you can’t get the big files) • A “self-serve” script to allow you to install everything you need to create your own Appliance on whatever flavour of Linux you like (so long it is Mint 16.0 17.0 32bit or Ubuntu 14.04 32bit. Mint 16.0 won’t upgrade to GNS3 0.8.7) • Just the WorkBench labs and exercises along with their instruction files. These can be added to your existing Windows or OS X install of GNS3 to give you the essential elements of the WorkBench in the comfort of your own favourite Operating System. This version is only possible because of the great work did in fixing the Snapshot function and Instructions features in GNS3 v8.6. The Latest Features in a Nutshell • V8.7 New Features • New lab • Improved Instructions – relates better to the GNS3 snapshot system • Rewritten the script file that allows you to change the image that is used in the WorkBench and GNS3 Vault exercises. The new script gives you a menu of images you can use to replace the one used in the WorkBench exercises.

The menu is created from the list of images you have already added via Edit IOS images and hypervisors • Existing V8.6 Features • Labs are now based on GNS3 Snapshots – so you don’t need to run a script to load the appropriate exercise, you can open exercises/labs from within GNS3 • The help system is now html based, and is integrated into the Help Instructions feature that was introduced into GNS3 v0.8.5 • Since GNS3 now has VPCS incorporated into the Tools VPCS menu, there is no need to load VPCS via a startup script to run labs/exercises. • The above three features have removed now make it possible to deliver a Windows/OS X version of GNS3 WorkBench. • Labs have been updated to more closely reflect the September 2013 changes to the CCNA exams.

• Over 20 new labs/extensions to labs. Mostly troubleshooting exercises added to tried and true labs. • Total of 50 different Labs/Scenarios • Total of approx 140 different exercises/solutions (Snapshots) shared between these labs. • Ability to add your own exercises – just save your own snapshots and add your own instructions. So what is GNS3 WorkBench anyway?

GNS3 WorkBench is a Appliance running Linux Mint with (almost) everything you need to make GNS3 run already installed, including: GNS3; Wireshark; Qemu; Oracle VirtualBox; Virtual PC Simulator (VPCS); Konsole; Putty and Xterm. It also has a collection of public domain images (Microcore Linux and Vyatta routers) installed and ready to go. As well as a comprehensive collection of over 140 exercises/labs.

Cisco IOS images for Dynamips. GNS3 offers multiple. Different IOS image. Are the default settings in GNS3. IOS 15 (Mainline) This router series is still.

New to GNS3 and dont know where can I download CISCO IOS. GNS3 is great for simulating routers but doesn't do a good simulation of. IOS image distribution is. But this Post is related to Gns3 IOS images for Router, there are many GNS3 IOS for routers but one of the most stable IOS image is Cisco 7200 series IOS.

(The Winows/OS X version is just the collection of exercises and public domain images). To run the Appliance, you will to add VMware and a Cisco IOS for an instant GNS3 WorkBench environment. To run GNS3 WorkBench Windows/OS X version, you will need GNS3 already installed on your Windows/OS X computer, and you will need to supply your own Cisco IOS Image.

Well – the best way of course is to! I used to ask people to sign up for DropBox – so they would get more space and so would I. Thanks to all those who clicked my link and signed up I’m maxed out – but if you, that you will get an additional 500MB of free storage. Hi Chris – Its been awhile but I’m finally jumping back into GNS3. I have to say the new version of GNS3 and your new version of Workbench are a vast improvement over the previous iterations! Thanks for all your hard work in providing this invaluable resource to the masses interested in learning networking! Now on to the problem I’m having.lol always a catch.

– I don’t have access to, nor can I locate a copy of the desirable 3725 image.anywhere. I’ve even checked with colleges that have support contracts and they can’t locate it? What I do have access to seems to be any other 3725 image imaginable. I’m exaggerating of course, but that seems like the situation. Anyway I’m not going to ask for the image because I know you’ll tell me to go get a support contact with Cisco. What I am going to ask is when I load up a c3725-adventerprisek9-mz.124-15.T8.image and try to do the ICND I configure 2 IPv4 Routers exercise I can’t get OSPF to seem to work properly. In addition when I load up snapshot 8 which already has it configured it doesn’t seem to work properly either.

It works between the serial connections on the two routers but it doesn’t work to route the traffic between the client interfaces. Same for when I load up the snapshot with static routes configured. Is this because I’m using a different IOS image? Is this a known issue? If so what can I try to resolve it? I’m as anxious as ever to get into networking but these constant hangups with all available educational resources are a real bummer. Again thanks for all your hard work, the new workbench is amazingly easy to get up and running compared to previous versions where I had to spend days troubleshooting before I could get started on any kind of network learning.

First of all understand that there was a major change in the way GNS3 worked between GNS3 v0.8.7 and GNS3v1.x.x My GNS3 WorkBench v8.7 is based on the old v0.8.7 GNS3. But it is stable.

GNS# WorkBench v12.3a is based on GNS3 v1.23 – which has since evolved into v1.3.10 and soon to be 1.4.x (which will be different again to v1.3.x). Confusing isn’t it? So – in plain English. The old GNS3 WorkBench (v8.7) works, but is stuck with the “old” version of GNS3. You WILL have problems if you then upgrade the version of GNS3 – the WorkBench exercises will no longer work. The newer GNS3 WorkBench (v12.3 or 12.3a) is at least using the newer version of GNS3, but not the latest, and you may have problems if upgrade the version of GNS3.

HTH RedNectar. Hi Chris, Thanks for taking the time to respond. I tried to run the script on Mint 17×32 as you showed that was the highly recommended version to use and I had the same issue however Mint was kind enough to give me an error message that clued me into what was going wrong. $HOME/.dmrc file is being ignored. I assume this is due to some of the permissions being changed from the setup script. I was able to correct it by doing the following: sudo chmod 644 ~/.dmrc sudo chown /home//.dmrc sudo chmod 700 /home Some things still don’t seem quite right but this allowed me to login via the GUI again. I haven’t tried this on Ubuntu but I think it will correct the problem there as well.

I’ve been naming my user “gns3” is this the cause? Thanks, Keith. Welsh, Perhaps I’ve missed a step or perhaps I’m just too new to OSX but I can’t seem to get GNS3 Workbench 8.7 working on OSX Mavericks 10.9.5. I’ve installed the latest GNS3 and it loads just fine. I’ve added the IOS images to GNS3 per instructions given on the GNS3 site.

Into Mac HD/Users/me/GNS3 folder I created /Images where the IOS, ASA and Junos images live as well as where the “extracttouserGNS3folder.zip” has been extracted and the image folder from that.zip added to the one I made. After reading the Readme.html I can’t seem to repack the ASA image and I’ve run the Junos.sh image by changing the extension to.command but it doesn’t do anything. On top of those two issues none of the.net files in the vault or workbench projects will open in GNS3. I can send screenshots if you’d like. Corel Draw X5 Full Crack Indir Ve. I was hoping you could help or maybe if others have had this issue. Can anyone suggest a fix (thoroughly explained though, I’m newish to OSX).

I have a question regarding your ready-made shortcut folders and exercises I can’t seem to ping the gateway once I followed your instructions for example snapshot 0 of ICND 1. I have configured the ip address and the gateway, unshut the gw interfaces, making sure they are on the same subnet How come eventhough I changed the IP address of the VPCS it doesn’t seem to reach the GW? My firewall is off, I have restarted my PC to make sure udp 20000 and 30000 is not used.

Please let me know what I need to do? I followed your troubleshooting guide here: But it doesn’t even seem to ping it’s on gateway first. Can you point me on what I am doing wrong here?

Hi, I was able to uncompress archive 1 and 2 but they uncompressed on 2 separate folders, so I manually move it. I double clicked the icon with the vmx file extension and was able to run the linux mint desktop. I can’t seem to share my folders, so I tried to install vmware tools but now I can’t seem to see the shared folder, If I go back to vmware machine library, it says there cancel vmware tools installation How can I successfully install it so I can run the shared folders since my iOS is in my USB drive or in my OSX folder thanks.

So, I have Ubuntu 14.04 LTS (x64), and have downloaded the large files twice (thinking I got a bad download). When I run the terminal commands to unzip, I get the following errors: Archive: GNS3WB86.zip warning [GNS3WB86.zip]: zipfile claims to be last disk of a multi-part archive; attempting to process anyway, assuming all parts have been concatenated together in order. Expect “errors” and warningstrue multi-part support doesn’t exist yet (coming soon). First of all, thank you so much for putting this together! I’ve been dabbling with Cisco and GNS3 for a couple of years now, but I’ve decided to do it properly now and aim for the certs, and GNS3 Workbench looks absolutely perfect! I already have the latest version of GNS3 installed on my Windows Laptop (Core i5, 6GB Ram), so I’ve downloaded the Windows version of Workbench and integrated it (hopefully, correctly!). I have a couple of issues though.

Firstly, I thought I’d start with the ICND – Simple Switching Exercise. I completed the first couple of steps, and got the Etherswitches and VPCs pinging each other no problem. However, when I do a show mac-address table on the switches, the CAM table either show up as completely empty or with just the last couple of MAC addresses. Repeated show mac-address-table show that the table gradually removes the entries until it’s empty, normally within 30 seconds.

I’ve checked the ageing time of the CAM table is set to 300s, and also tried various values between 300s and 1200s, but nothing helps. I’m using the recommended IOS for the c3725 (T10), but I’ve also tried with the T14 release and observed the same behaviour. I’ve been Googling for a couple of days, but can’t find anything that really relates, so I think I’m a bit stuck on this one! Secondly, just a quick question about VPCS. When I load the exercises, am I right in thinking that I have to manually configure the IP addresses on the individual VPCs? I’ve done it no problem, and saved the config so I can quickly load it, but I’m just checking that I’m not doing anything wrong! Sorry, just thought of another quick one too.

When I load a snapshot for a topology, I get a message saying that the IOS image can’t be found. I get an option to choose the correct image, which is invariably the same file. The only difference that I can see is the path.

The images that I can use have the full paths (C: Users Rob GNS3 Images imageName.image) to the image listed in the dialog, even though it’s in my specified “Images” folder. I can fix this by editing the toplogy file to point to the full path, so again, it’s not a massive issue.

Just wondering if I’m doing something wrong! So, that’s all! Sorry to bother you with all of this, and thank you again for all your work.

Just show me where to donate! Hello, I have downloaded the large files from version 8.6 call.zip and.z01 at the end but I can’t figure out how to unpack on my computer.

I work with OSX Maverics and have tried the incuded archiver, KeKa and Zipeg utils, all give an error or only extract the first file to an.zip.cpgz file. To be sure, I also tried WIndows 7 archiver and 7-Zip at a windows computer, but it fails. Then I tried the small files, but the same problem with the single vmdk.zip and.z01 file pair.

Plain.zip is going well, no problem, but a split zip gives me headache 🙂 Wrong files? Or wrong methode by me? Thanks in advance, Marco. This on is curious, because the zip files were actually created on OS X using the zip command.

But when I tested the archive on OS X all i did was locate the.zip file using and double-click on it – and it expanded perfectly! However, for some reason Apple’s own Finder.app is too stupid to know how to do this.

What’s more the OS X version of unzip doesn’t know how to do multi-part archives either. So until I find a better way, I’ll have to suggest that you use – you can get a trial version for free, but you may find that it’s worth buying (one of the best programs I have purchased – see ). I haven’t tested, but I have heard that is a good free zip expander for OS X. Edit: Sorry Stuffit is only a free trail – best to use – also free from the Apple store.

Once installed, just right-click on the.zip file and open withThe Unarchiver CW. I think I know. I always use the free KeKa for OSX to create spanned zip files, and have KeKa as default archiving program in finder. Curiously is that Zipeg and KeKa both don’t know how to extract a spanned zip file which is created with the default archive program (zip?). Best: is to make the OS X archiver again the default uncompress program, the unzip with finder works fine now. My methode: with finder first unzip the filename.zip file, it gives a filename.zip.cpgz file, then unzip this one also, and it will unzip the filename.z01 also and I got finally the full uncompressed file.

Thanks for the tips about KeKa and Zipeg. Pity they don’t work.

I’m sorry, but I didn’t get any success by “first unzip the filename.zip file, it gives a filename.zip.cpgz file, then unzip this one also” – all I got was a filename 2.zip However, I have found that the free The Unarchiver utility works just fine. After installing The Unarchiver, simply right-click on GNS3WB86.zip and choose Open with The Unarchiver to get a successful decompression.

Is also available free from the App Store. Why don’t Apple provide this as part of the the OS? It beggars belief! Hi Milan, Run an md5 check on the files you downloaded (BOTH GNS3WB86.zip AND GNS3WB86.z01).

If they match these numbers: MD5 (GNS3WB86.z01) = ad1c2451af6d MD5 (GNS3WB86.zip) = 7e4eacebe931e12c9c61bb Then *I* have a problem that needs fixing. If your MD5 calculation does NOT match these numbers for either file, try and download it again, of if that doesn’t work, try the “SmallerFiles” option. Note: WinMD5Free () is a free app that you can use to calculate MD5 checksums on WIndows.

On OS X, just issue the command md5 GNS3WB86.z* in the directory where you downloaded the files. At the moment (Apr 2 2014) GNS3 WorkBench is being updated. I have uploaded a single image of v8.6 that no-one seems to be able to download. I have been (almost continuously) being uploading the same image, but as a collection of smaller files hopefully that will be finished in about 24hrs – I had staged that folder so no one could get to it, but that expires after 3 days, which means you have access to it.

I’ll leave it open so you can start downloading – but at this instant in time don’t bother downloading the following: Virtual Disk-s001.vmdk.zip 950,014,837 when complete Virtual Disk-s004.vmdk.zip 260,691,373 when complete Virtual Disk-s015.vmdk.zip 758,288,665 when complete Virtual Disk-s016.vmdk.zip 1,904,553,448 when complete Virtual Disk-s017.vmdk.zip 720,738,589 when complete Virtual Disk-s019.vmdk.zip 91,811 when complete The other files should be OK CW. Ed, I was able to use the latest WorkBench VM image and imported it to get it working with ESX. This was with an old ESX version (4.1) but I also used the converter to get it to our new 5.5 ESX server. However, I’m having trouble getting virtual routers to talk through a cloud to my network. The odd thing is that the virtual routers are getting IP addresses assigned by the DHCP server on the network that the Host VM is connected to but they can’t ping the Host VM or the default gateway on that network.

What’s even more wierd is that the default gateway router gets notifications if the duplex is mismatched but still can’t ping it. It seems that broadcasts are making it out (which is why dhcp works) but no pings or other tcp traffic. I would appreciate any ideas since it’s been frustrating to be so close but still not have GNS3 routers be able to interact with real machines. Glen Sonnenberg Packet Design. Hi There, many thanks indeed for the reply.

I must admit, I have been at this for 3 day (but Im not giving up). So I am trying to run Titanium and need to get Qemu working on GNS3 workbench. Just to say wow, what a great distribution, so fast and straight to the point so many thanks goes to everyone who has participated in this. So Qemu is not working, so I am going to install Qemu from source and apply the olive patch. The problem is, that when I use apt-get, it does not find any software what so ever, ie, try to get the patch program so I can patch and I get the no software found. I try to look for know applications like vlc, and I get the same, so I assume (not being the best linux person in the world) that I have an issue with the apt-get and potentially the sources.list file. I am using the default one that comes with the GNS workbench distro as I have changed nothing on it.

So hopefully by the end of the day, I will have QEMU working on GNS workbench and the apt-get working, and then run an n7k with Titanium 5.1.2. I can get the n7k working just fine under a normal vm instance without GNS3 with no system crashes, but I need to be able to run a pair. Will also try and fine a download for the new update 6 version (hard to find currently) I have also tried Titanium under windows, and GNS and keep on getting system crashes, and now I have GNS3 on fedora and got qemu working, but now I keep on getting system crashing on the n7k when I bring this up. I AM NOT GIVING UP 🙂 Its hard not being linux gurus but I am learning and thats what it is all about in the end. Any pointers would be very well received. You guys are doing a fantastic job and providing a great service.

Very well done, Ken. I’m having an issue with installing Qemu on WB 5.8 I’m running VMware Fusion 6 on OSX 10.8.5. When I try to use the “adt-get install” I get this: ********** user@GNS3WB:Project$ sudo apt-get install libncurses5-dev zlib1g-dev libsdl-dev libpcap-dev Reading package lists Done Building dependency tree Reading state information Done Package zlib1g-dev is not available, but is referred to by another package.

Chris, As an educator, I find the GNS3WB super helpful. I believe that the biggest problem in networking education is the significant configuration overhead in illustrating a single concept (static routing, dynamic routing, VLANs, etc, etc.). Your “one-click” labs in GNS3WB completely sidestep this problem and have allowed me to create homeworks and labs for my students built upon your framework. However, the current GNS3WB is totally outdated. I have been waiting since 6/2013 for the next promised version of GNS3WB.

I have a feeling that, like me, there are many other beneficiaries of GNS3WB that would be willing to help you develop the program (especially now that it’s near a single script install) if you would be willing to open it up to a community development model (perhaps on github). I would personally be happy to help you polish this awesome tool (for my own selfish interests in the classroom)! Please let me know how I can help get this next version of GNS3WB, “over the hump!” Cheers, – Rob. Thanks for the offer Rob – most of the work is juggling the existing structure of the exercises to fit the new directory structure as per the most recent changes to GNS3 – the install script is pretty much written – but the bit that copies all of the “WorkBench” files to the new install doesn’t have the modified “WorkBench” files to copy. I’ve just had two weeks away, and am clearing up my backlog. If you are interested, I’ll send you a copy of the script as it is so far to test – but it won’t install any WorkBench features – but it will get GNS3 installed and a few other things too.

I am jsut dropping a quick note to tell you how I appreciate this tool. I installed GNS3 on my W7 machine, but I wanted to do the same on something portable. I tried to put an Ubuntu install (10.04) on an USB hard disk, but I never succeeded in having everything run together. As soon as I solved one problem I ran into the next one. So I had given up when I found your Workbench. I opened a drop box using the link, I hope you got your extra space from that.

I think you could use a paypal account if you would like something extra. I had planned to release when GNS3 0.8.4 was released, but 0.8.4 has a which so I’ll hold off till then. However, I can tell you that the next release will come in a couple of formats – one of these will be a script that will assume that you have already got a VM of, and that will probably be the first release. The VM version will be built on Linux Mint 15 “Olivia” – Cinnamon no-codecs (32-bit) since 32 bit is more global. However, there is a problem with shared folders with Linux Mint 15 (both on VMware and Parallels. Haven’t tested VirtualBox) So my advice right now would be to stick with 5.8 release – the next version is at least 2 weeks away. Unfortunately I tried that and it didn’t work.

From what I read they no longer use the admin group, its sudo now. So I used sudo instead but also tried creating admin group and no luck. Right now I have a freshly created vm of Ubuntu 12.04LTS x64 with everything properly installed and working But the scripts only work if I right click and open folder as root then start the scriptsor log into root. Example: right click on Standard layouts on desktop open as administrator (had to add a nautilus extension to do that) input password then click on “1 Router (reset lab)” and GNS3 and the konsole window with vpcs and instructions work. *Had to reinstall vpcs Thanks again for all the hard work now I can work on getting my CCNA Bill.

Hey Geo, yeah ESXi, especially when managed with a vCenter server utilizing VDS (vDistributed Switchs) greatly complicates things. But even at the most basic level (VSS, vStandard Switches) ESXi abstracts the physical nic’s away making it tricky to know what pnic is really doing what plus esxi inserts a lot of odd but useful layer 2 manipulation.

With VDS it goes from tricky to downright insane but equally as useful. But it’s absolutely doable.

Unfortunately the configuration of VSS vs VDS is completely different in every possible way, the only thing they share is the nomenclature of the nics vmnic and vmk. Cisco’s nexus 1000v which replaces all of VMwares layer 2 services greatly simplifies things but it’s expensive and not widely used outside of the BIG boy’s.

Without knowing more about your setup I can say is that regardless of what switching your using (VSS or VDS), vlan tagging is by far the most common thing that trips people up. VMware’s switching has no concept of the native or untagged/mgt vlan (outside of not setting a vlan or leaving it at None (0). While the default native vlan on all cisco stuff is vlan 1 which I change to 4094 immediately. It’s more complex to change it from 1 but it greatly simplifies things when things get really complex with vmware integration. On the bright side, if you don’t have your arms around vlan tagging this is a perfect scenario to lay a solid foundational understanding of it. Then it’s probably VLAN encapsulation, the older cisco IOS’s mainly used in GNS3 default to ISL (cisco’s proprietary tagging) so just be sure to always explicitly use dot1q.(example #int gi0/10; #switchport trunk encapsulation dot1q).

After that and if your using VDS, if frames aren’t making it through the GNS3 cloud to the real hardware go into the properties of the distributed port group you’ve assigned the gns3 cloud nic to and change “promiscuous mode” and “mac address changes” (found in the Policies ->Security section) from reject to accept. And lastly, if you’re proficent with VDS and have tried the above to no avail there’s a 99.999999% it’s a bug in ESXi’s networking that’s been addressed in a minor patch you can apply. That’s happened to me 3 or 4 times in the last 3 – 4 months. Feel free to post more details about your setup and we’ll see what we can do.

How to convert GNS3WB to ESXi from ESXi command line: Get the WorkBench to your esxi storage via scp or vsphere client ssh into esxi server or access the console with Alt-F1 over ipmi1.5/2 or from local keyboard and cd into the WB folder If they’re still zipped do: for i in *;do unzip “$i”;done 1. Convert and consolidate VMDK’s from Workstation to thin provisioning (in this example) /vmfs/volumes/OpenFiler/GNS3WB58 # vmkfstools -i ‘GNS3 WorkBench.vmdk’ -d thin ‘GNS3 WorkBenchC.vmdk’ 2. Edit vmxf file to reflect the new consolidated vmdk name /vmfs/volumes/OpenFiler/GNS3WB58 # sed -i s/WorkBench.vmdk/WorkBenchC.vmdk/ ‘GNS3 WorkBench.vmx’ 2.1 (Optional) You can delete all the uneeded vmdk files now if you want /vmfs/volumes/OpenFiler/GNS3WB58 # rm GNS3 WorkBench-f* GNS3 WorkBench.vmdk 3. Through vSphere client delete all 3 nics 4. Through vSphere client add 3 “VMXNET 3” nics Then start up the vm and enjoy You can probably copy and paste below: vmkfstools -i ‘GNS3 WorkBench.vmdk’ -d thin ‘GNS3 WorkBenchC.vmdk’ sed -i s/WorkBench.vmdk/WorkBenchC.vmdk/ ‘GNS3 WorkBench.vmx’ rm GNS3 WorkBench-f* GNS3 WorkBench.vmdk.

Hi Chris (or maybe somebody else can help me out) I’ve done some of the ICND1 execises but now i’m stuck at the “SDM DHCP & NAPT”, the problem is that i have to configure eth0 with an ip address 10.10.10.x/29, i did that (10.10.10.2/255.255.255.248) but i’m unable to ping or connect to the router using 10.10.10.x network from the vm, or i don’t understand which of the NIC’s i have to configure with 10.10.10.x/29 i’ve tried the other interfaces as well but no luck my vm interfaces are eth0 – bridged, eth1 – NAT, eth2 – Host Only here is my ifconfig output.

Ok, i’ve done it however i had some trouble with SDM, so maybe this will help somebody else. First install a loopback interface on your host (windows, or whatever) Configure the loopback interface with 10.10.10.0/29 (just don’t pick 10.10.10.1) i’ve used 10.10.10.2 for the host (windows) and 10.10.10.3 for the guest (ubuntu gns3 workbench) I don’t know if this is a must, but i’ve done it edited vmware workstation networks and added a new bridged interface and selected the windows loopback interface to bridge with I’ve edited the workbench proprieties and removed all NIC’s, then added one NIC, the one bridged with the loopback. Started the VM, configured eth0 with 10.10.10.3/29, started the exercise and routers, this time worked. From my host pc, i could ping 10.10.10.1 (router’s fa0/0), 10.10.10.3 (linux guest eth0) As far as i know SDM it’s not installed on the router when you start it up, so i installed it on my host pc, i could connect with it to the router but some futures are not working i.e.

Clicking on some buttons, i’ve searched around and it looks like it’s a java incompatibility. After this i’ve uninstalled SDM and installed CCP, CCP worked with jre 7 and i finished the exercise 🙂. Firstly, thank you for putting the effort into maintaining this fantastic resource!! As someone currently doing my CCNA, and unfamiliar with the Cisco world, I found the biggest hurdle with GNS3 is trying to figure out working combinations of IOS images and virtual hardware in GNS3.

I dare say, other newcomers to GNS3 are also in the same boat. Any chance you could include inside your workbench/appliance a list of known working SW/HW combinations including: (a) IOS image name (b) Configuration parameters for the GNS3 virtual device hardware I must have wasted half a day yesterday blundering along in the dark until I happened to find a working combination. *** I am NOT asking for the actual IOS images, just to know what virtual GNS3 hardware is needed for, say 3 different models, with serial and ethernet interfaces. SGX, I feel your pain!!!!!!!!!

In fact, it was this kind of difficulty that I wrote GNS3-WorkBench to try and overcome as best as I could. Unfortunately, I had to stop just short of supplying the IOS image!!! The battle of trying to match IOS versions to hardware capabilities has been a problem for a long time. The BEST place (not a good place, but still the BEST place) to work out which image works with which hardware is the cisco website: specifically (you probably have to register first) As for the configuration parameters – again – that takes a bit of learning, and again the idea of the WorkBench is to get you started before you have to know that stuff – and when you are ready, you’ll have to read the And finally – my advice is to not worry about 3 different models – just work on learning how one model works, and you’ll be able to transfer that knowledge to 90% of the remaining models. I have written the WB exercises specifically for the C3725 and ideally using c3725-adventerprisek9-mz.124-15.T10.bin – but if you can’t get this particular image, another 3725 will probably do. Well how about that.I guess it just needed a good assblasting First attempt: root@GNS3WB:~# tunctl The program ‘tunctl’ is currently not installed.

Any advice on how to increase the space would be greatly appreciated since I am not a Linux wizard:( If not, could you please create a new distribution with a larger partition to be able to accommodate for the IOS files and projects? I do realize and appreciate your wanting to keep this distribution small. There are other alternatives to using ZIP that you may already know about. I recommend using RAR.

RAR allows you to reduce the larger files and folders into smaller chunks (in some cases it allows for file compression). Most people that download from the Internet already use it and it is supported by most programs that works with ZIP (i.e.

WinZIP, WinRAR, Total Commander, etc) The larger distribution will add to the initial download time, but will increase the capabilities to your GNS3 Workbench for future growth. Respectfully, Greg P. Chris I’ve tried to download gns3 workbench and all the files listed in the 5.8 folder have downloaded without any problem but GNS3 WorkBench-f001.vmdk.zip downloads only 703 mb opposed to 737 mb as listed although the download finishes without any errors but when I try to extract the zip it fails on 99% with a CRC error.I’ve download it with opera,chrome&IE and also with download manager but its the same story every time.I really need it to prepare for my CCNA.So could you please see into the matter as soon as possible. Thanks Aashish.

There are 6 zip files you have to copy and expand – it just so happens that the GNS3 WorkBench-f002.vmdk was the last one uploaded and so shows are “THE” file to download on sourceforge. To install successfully, you will need to download and expand: GNS3 WorkBench-f001.vmdk.zip GNS3 WorkBench-f002.vmdk.zip GNS3 WorkBench-f003.vmdk.zip GNS3 WorkBench-f004.vmdk.zip GNS3 WorkBench-f005.vmdk.zip GNS3 WorkBench.vm.zip The good news is you have downloaded the biggest file already, the others are at least a little smaller. More details at (Read the Steps below the files). Hello, I really like gns3 on linux, runs better in a vm than on windows itself. Also having it all pre setup is wonderful apart from having to supply your own IOS’s.

Before you release 5.8, I would like you to include some more features. Install a flash player for firefox. Provide the root password, every time I tried to su, I get authentication error. Setup some of the qemu’s like linux tinycore etc, I have been unable to get any working I get 209 error. Include some other software like ftp’s, subnet calculators etc etc. Also have firefox setup with a alot of good networking links.

Also have routers setup with more modules rather than just fa0/0 & fa0/1, I have been unable to work out how to add modules to routers. Run a compressed file system. Also do not have the vmdk drive span, most people use filesystems that can support 2gb+ files. Not a big issue but it is nicer. Thank you very much, sir!

Workbench rocks! And you must be the real deal, for sharing all this with us, the mortals! I had only one problem – couldn’t get QEMU running; under the qemu pref – second line (below the qemuwrapper) – where it says ‘qemu’, and the third line with the qemu image are both missing from the distro. The path points to nowhere and the linux cannot locate them anywhere.

Not a big deal, just wont be able to use ASA, still would be nice if somebody knows a solution. Unfortunately, I’m totally lost in Linux and cannot have QUEMU recompiled or the like. Keep up the great work! Your work Excellent The service and opportunity you’ve provide outstanding Your intelligent and timely response to your users and the clean, well designed web interface isn’t it just a bit sad that Cisco doesn’t see the value in promoting the use of GNS3 and providing an “educational” set of IOS’sso that aspiring, (potential) future advocates/representatives of their Market Share Industry, (the true promoters of Cisco’s product line and services) have a better tool, and thus a better understanding to carry into their careers sorryI almost digressed into a rant As I was saying. Well done and I ain’t easyI can count the comments I’ve left on websites on one hand(now, one hand and a finger of the other).

MPH Student Montana USA. You have already told about making download on torrent basis. Just like some of the guys who was dying to grab the workbench I was also one of them. I’m having problem downloading it at sourceforge. Using Free Download Manager I got stuck at 99% download and all it needs was around 20 mb of files left. Until all my prepaid connection was consumed still I was waiting for that 20 mb to fire up and got no result. I also tried Kget, Uget, DownThemAll and flashgot but all was a failure.

Even the Firefox download manager didn’t succeed. Can you imagine the frustration that I have after consuming 24 hours trying to get that file while I can download the same amount of file around three hours on a torrent site? Can you please do something about it?

Cris to upload it to a dedicated torrent site? Hello rednectar. A pleasant day to you. You know what?

I forgot to tell you last time that I have successfully download GNS3 Workbench at 4shared and I am soooo happy about it even though it was a rar files. It was dissected so anybody who has a low bandwidth internet can download it slowly piece by piece. Unfortunately to my surprise it was encrypted. It was asking for a password. Damn my heart broke because I am still halfway to my goal. I don’t know why you have upload that workbench to sourceforge where it cannot support low bandwidth download connection. I tried to please the guy who upload it and begged for the password but until now he was not responding.

Probably wanting some compensation to his upload where I cannot provide. Well I think I have come to the point where I must gave up hoping to download your workbench.

I guess it is only intended for the rich fellows in your circle. Best regards. Thank you very much Mr. Chris for the upload to 4shared. Since last night I was trying to download it using DownThemAll, flashgot using Firefox built-in browser and Wget as well as the Firefox’s direct “save at” button but to no success.

The problem is the server suddenly times out and it stops sending file fragments. I really don’t know why. I also tried Transmission last night but it only start this morning around 6 or 7 +8 UTC.

The torrent works but I was connected to only 2 peers which is quite very slow. Now that we are in the 4shared website does Mr. Chris knows about the guy who upload the same application in rar files? I believe he was using odin69 as his pen name. The creator of GNS3 workbench created it for free but he was making fortune out of it.

Anyway my download is around 70% now, I hope it’ll end before my 24 hour prepaid load runs out. More power to you Mr. Chris and Mr.

I just hope you could split the file in 4 and upload it again so it can be downloaded easily and without a password. OK Chris, Actually, one more item and I should be all set! I’m trying to use the Qemu Appliances with WB5.6 — but it looks like qemu is not included in this release? “Failed to start qemu” when I run the test button. Anything I’m overlooking?

I searched around and I see some of your older posts indicating that it’s not bundled in to some versions? Is it supposed to be in this latest one? I have the qemu appliances working great on my Host (Win7) and on a VMware Server2K8 R2 install — this is pretty cool stuff — especially the Linux TinyCore which comes up in a graphical screen!

(Perfect for a Linux noob like myself;o) I also have the VirtualBox appliances running on my Host machine. I went into Qemu prefs, but I can’t find a path for qemu and qemu-img. So, how would I go about getting this to work? Am I just missing the path?

Turns out it’s not necessary to do any bridging from vmnetcfg! Finally sorted everything out, and it’s working perfectly. What confused me (and ultimately helped me!) was configuring 3 variations of GNS3.

Maybe this will help others out there. The MS Loopback stuff is tricky. On my Host PC (Win7), I added the Microsoft Loopback adapter. Running GNS3 here, a Cloud sees ALL of the Host’s interfaces — LAC, LAC2, plus the VMware adapters, and VBox adapter! I configure LAC2 Loopback as: 192.168.254.10 /24 PLUS gateway 192.168.254.1 There is plenty of conflicting info on whether a gateway should be specified, but I found the only way to work is to add the gateway setting.

I connect this as a Cloud /MSloopback interface to a router port at 192.168.254.1 in GNS3. Next case, I have a VM running Server2K8 R2, installed a Loopback (LAC2) here also, and when running GNS3 here, the Cloud ONLY sees this VM’s virtual adapters LAC and LAC2! I configured it as 192.168.254.100 /24 PLUS gateway 192.168.254.1 This VM doesn’t see the original Host PC Loopback, nor the VMware adapters. I connect this Cloud loopback the same way, to a router port at 192,168.254.1 in this GNS3. Now — the trick — in both cases you have to go the PC Command prompt as Administrator, and add in a route back to the other ports of the router you’re connected to! For example, if the other port is 192.168.2.1, on your console, >route add 192.168.2.0 mask 255.255.255.0 192.168.254.1 -p This tip came from some excellent videos from Keith Barker at His video doesn’t use a gateway setting, but again, in my case it would not work unless I have the gateway specified. You can now ping from your console, through the GNS3 virtual router network in either one of these Microsoft environments.

Lastly, with the Ubuntu Workbench 5.6 VM, it finally dawned on me. Linux doesn’t see the MS loopback at all, nor does it need to! I went back and followed your 3 part series step by step, and everything worked perfectly, once I used the correct address.

I changed eth0 to be a NAT config, instead of bridged, and received an IP of 192.168.80.138. In your “1 Router (reset Lab)” dhcp assigned the router port to 192.168.80.143 That’s what I was missing! Now, from my Host PC (Win7) console, I can ping, telnet, and SDM to 192.168.80.143, and Life is Good! Option 2 does work as you explained.

If I set the 3 VMware adapters to NAT, NAT, Host-Only, I do get an Internet connection with Firefox. But very strangely, it doesn’t work right after the bootup! I found that if I go to Konsole and “sudo dhclient eth0” —- it then works immediately. I would have thought that doing a startup would have reset all the IP settings, but something stays stuck.

Anyway, I then tried the Cloud configured to eth0, setup a router with a dhcp interface, and a default route, and voila! I’m pinging public Internet addresses. I can capture these packets with WireShark (although I had to change the default Capture launch preferences to ( tail –bytes=+0 -f%c wireshark -k -i – ) I also bumped the RAM to 2GB for the VM, and removed the Shared Folder link that pointed to your user account;o) Now, the last bit to figure out getting the Loopback to work. I’m probably missing something here. I configure a Cloud with lo interface. Connect it to a router, but what address to use to connect back to the Host? Lo shows as 127.0.0.1 Here’s my setup: Host PC runs Win7 x64, Q6700, 8GB RAM.

Network has 1 Ethernet card as L.A.C, and Microsoft Loopback adapter on L.A.C.2, and the VM adapters. Cable modem connects directly to LAC, only 1 IP address. I configured the Microsoft Loopback as 192.168.254.10 /24 + G.W. 192.168.254.1 Soooooo, I should be able to use a GNS router address of 192.168.254.1, right? From Konsole, I can ping 192.168.254.10. But from the GNS router, nothing comes back when I ping 192.168.254.10, and likewise nothing on the Host PC when I ping 192.168.254.1 On Win7, I turned the FW off, no difference.

I’m stuck here. I have another VM running Server2K8 R2, and installed the “All in one beta 0.8.2 GNS” on it, and added a Loopback Adapter to it. (The equivalent of your lo?) But I didn’t use 127.0.0.1 for the address, I used 192.168.254.100, and it works great! From within GNS, routers set as 192.168.254.1 can ping back to 192.168.254.100. What do you make of it Chris, do I need some address other than 127.0.0.1 on lo, or something I’m missing?

Thanks again, Jerry. I’m not much help here – I’ve never played with the loopback interface – I know you need it for some Windows things, but I’ve always used Linux or OS X so haven’t bothered. However, if I understand you correctly, you want your GNS3 Router (running in the Guest VM) to be able to connect to the loopback adapter of your Host PC – which is Local Area Connection 2. What you will need to do is set up a bridged connection between your LAC2 and one of the virtual interfaces on the Guest OS – using the vmnetcfg.exe program you already know about. The bridged connection will (probably) end up being eth1 or eth2 in Ubuntu, and in GNS3 you will need to link your cloud to the correct ethx HTH.

Chris, Thanks for an outstanding project, I’m sure everyone understands and appreciates the time and work that went into creating Workbench. Your explanation and examples about VMnetcfg and the VMware adapters are the best I’ve seen — I think I’ve finally got it right now! I do have an issue, and I’ll try to be succinct here — I don’t have a wireless router, I connect directly to a cable modem. It only hands out one IP address, so I think you can see where this is going. Eth0 never gets an address, and ifconfig shows eth0:avahi as 169.254.x.y Now, at first I thought I had all the network settings messed up, but I’m using your standard build with VMware player using the 3 adapters as Bridged, NAT, Host-only. Through lots of trial and error, I found that I can ping public Internet addresses immediately after booting up, but Firefox will not connect to any websites. However, after about 20 minutes or so, Firefox works perfectly!

Must be using the NAT adapter, but I don’t know why it takes so long to start working. I can see that your entire setup is dependent on having a separate router that hands out an IP to the host machine and to the Bridged eth0 interface. Can you suggest a way to get this to work with just a cable modem? Eth0 affects the Internet connection, Wireshark captures, and GNS3 connecting to the Host PC.

It would no doubt work fine if I had a wireless router, but there must be a lot of others out there that give this a try and run into the same problem with cable modems! Thanks for any advice, Jerry. Thanks for the kind words Jerry. You seem to have worked out that when the VM finally worked, it must have been using the NAT adapter. Why it took 20 mins is another issue. It could be that your Guest OS (Ubuntu/GNS3 WorkBench I assume) had the primary adapter set to “Auto Bridged” – I have seen this cause a few similar problems, but without the setup in front of me I can’t come up with anything better.

In my explanation of the adapters, I did indeed assume that you would be using an external router rather than using a USB connected modem. Now I’ve never used a cable modem that didn’t have an Ethernet interface, so I’m not entirely sure how the cable modem interfaces with the PC, but I’m going to take a stab and assume it is like a 3G modem, which gives you an additional interface on your (Host) PC – “Local Area Connection 2” or something similar. The problem is that if you bridge this interface to the Guest, then you’ll need to get another IP address from your service provider – which of course they are not going to give you! As for getting it to work, I need to know exactly what you are trying to achieve.

Do you just want your VM to have access to web pages and the internet in general? Do you want to have GNS3 routers running on the Guest (GNS3 WB) accessing the internet interface of the host PC? If you only want (1) then set your first Virtual interface on the Guest (GNS3 WB) to be NAT rather than Bridged.

To do this in VMWare Player, go to the VMWare Player menu->Removable Devices->Adapters->[1st adapter]->NAT Your eth0 interface of your Guest (GNS3 WB) should get allocated an IP address something like 192.168.x.x and a default gateway of 192.168.x.2 and your Host PC is now acting as a NAT router between your Guest OS and the internet. If you want (2) as well, probably the easiest way is to create clouds in GNS3 WorkBench that link to eth0 of your Ubuntu. Connect the cloud interface to a GNS3 router – say f0/0 on R1. Now for an IP address for f0/0 on R1 – use ip address dhcp and it should pick up an ip address from your Host PC. Also on R1 you will want to add a default route to 192.168.x.2, the same as your Guest OS. I know this is a bit sketchy – I’m a bit pushed for time at the moment, but let me know if you need more detail.

Hi Chris, I installed Ubuntu 10.10 1. Removed unwanted packages and Updated the remaining packages 2. Installed GNS3 0.7.4 with Dynamips 0.2.8 RC3 community version 3.

Used VPCS 0.21a 4. Installed Konsole 5.

Set the new IdlePC values 6. I will set up ASA and Pemu Now i can start upto 8 routers with 1024 RAM allocated for the VM, Everything works fine GNS3+Routers+VPCS+Konsole, I tried your script (run.vpcs) to start VPCS it is not working for me changed trying the path to VPCS without need your help to run VPCS, using script.

Hi Sathya, The first thing that springs to mind is that after you have copied the scripts to the new install, you will have to make them executable again. Hi Sathya, I did a document called diary of tweaks made since install – or the full path is: /opt/GNS3/READMEs & Scripts/diary of tweaks made since install In this I describe how I installed Konsole. It is as simple as: System->Administration->Synaptic Package Manager Search for konsole and install (this downloaded 72 files) The whole idea of this file was to allow someone like yourself to try and repeat the install.

Many of the scripts depend on the superuser password being password, so if you are doing your own install, I suggest that you stick with that. I created a user called user with the password of password. Once you have it all installed, you should be able to copy everything from /opt/* (including subdirectories) and /home/user/Desktop and pretty much get it going. If you’d like to record your progress, I’d love to put it here as a feature article.

Chris (RedNectar). Rish, The guys at gns3.net do all the hard work, I just get it installed on a Virtual Machine and put a few script files around it to make it easy for people to get started. Once you get into it, you will probably create your own topologies and problems, and won’t need the WorkBench format.

So to answer your questions: 1. After GNS3 WorkBench.? I don’t have anything specific yet. Maybe do some more certs 😉 2. Emulating switches isn’t going to happen on gns3 as far as I know – you are right, the ASCIC hardware can’t be emulated in software (without reverse engineering).

If you want switching emulation, you’ll have to go for, or more specifically L2IOU, which is now operational in the CCIE exam. The first thing you should do about the lack of L2 support is sign – and to be fair Cisco have made some progress in this area with the announcement of their which use IOU and L2IOU. Beyond that, who knows what the future will bring? Will and change the whole ballgame as far as switching/routing is concerned, especially if? Will the mean that we no longer need vendors like Cisco? Enough rambling for now, Chris (RedNectar). Rishi, When you start a lab, the script looks for an uncompressed image following the convention that the uncompressed filename ends with.image – as recommended by Greg Anuzelli in his.

If you have put an IOS in the IOS directory, AND decompressed it AND named it xxxxxxxxxxx.image then the labs should attempt to start. Be aware that the labs all assume that the image you are using is c3725-adventerprisek9-mz.124-15.T10.image. If you are using another image, you will have to run the script /opt/GNS3/IOS/script to change firmware image. More detailed instructions are in the. Good luck, hope you get it working soon. Chris (RedNectar).

First let me say this is a great tool and I really appreciate everything you have done here. Now I have a question, because for the life of me I cannot get the cloud setup to work. I have the box running on esxi 4.0 and everything works great, but no matter what I do I cannot seem to access the SDM lab or even get ping working to gns3.

Can anyone what exactly I should need to do here because from all the digging I have done it should be as simple as setting the interface in the cloud configuration. Hi, 1) I’m not sure of the process to increase the disk size on a Windows machine, but I believe that will tell you. For Macintosh (VM Fusion), you simply follow these steps. I) Make sure the Virtual Machine is shut down ii) Make sure you have a backup of the VM iii) Go to VMware Fusion ->Virtual Machine Library and select the VM iv) Click settings v) Click Hard Disks vi) Move the slider or type in the new value for the size of the hard disk you want. Vii) Click Apply 2) I can’t add special labs like CCIE labs from ipexpert or ine because these labs are copyrighted.

However, if you have purchased these labs, then it would be theoretically possible to integrate these labs to GNS3 Workbench. If someone wants to submit a network design that they’d like included (for CCIE or any other purpose) I’ll consider adding it to the next update. It would have to be an original design and guaranteed to be original. Hi Mate, Fantastic work!!!!! I have made the following changes to the package; Converted the vmdk disc from Thick(pre-allocated) to Thin and grew it to 20Gb. Added an Olive Image for Junos, still tinkering with this got it functioning in windows GNS3 so know the olive is good Got Pix working fine I am now looking to upgrade the GNS version to latest so you can save mutiple ASA and JunOS builds. Awesome work on the lab setup scripts!!!

I am hoping to use your format to build some security based labs. Thanks again Scott. Frank, Good luck with your studies! There are a couple of ways of accessing your lab remotely – the one I have had most success with is where the PC running GNS3 Workbench VM is a Windows PC that can be accessed remotely using MS Remote Desktop connection – so in your case you’d have to access your host OS Win 7 Pro. Now setting up your home network to do that could be tricky, but (assuming you have a public IP address on a router that does PAT for your internal network) if you can forward traffic to port 3389 to your Win 7 Pro PC (and of course make sure your Win 7 Pro PC can accept RDP connections) then you should be able to do it.

I have seen this work very successfully with one of my customers who run entire remote workshops like this using a classroom of PCs at their central office. To elaborate – let’s assume your Win7 Pro PC has an IP address of 192.168.0.4, and your public IP address of your home ADSL/Wireless/??? Router is x.x.x.x Firstly, set up your windows PC to accept incoming Remote Desktop connections. Control Panel->System & Security->System->Allow remote access Next, you’d have to set up your router to forward incoming connections for TCP port 3389 to 192.168.0.4 – just how you do this will vary from router to router, and this is a skill any CCNA candidate should be able to master. Now (from home) visit whatismyip.com to find out your public address – x.x.x.x Finally, from your remote site, use MS RDP application (Accessories- Remote Desktop Connection) to access x.x.x.x – this should take you straight to your home Win 7 Pro PC. An alternative option is to allow VNC access to the GNS3 Workbench desktop VM (From VMWare Workstation: VM->Settings->Options Tab->Remote Display) Now forward TCP port 5900 on your home router to 192.168.0.4, and use some VNC viewer to access x.x.x.x – it will take you straight to the VMware Ubuntu desktop The third alternative is to assign an IP address to the Ubuntu VM – say 192.168.0.5 (sudo ifconfig eth0 192.168.0.5 – pasword is password). Now configure your router to forward TCP ports 2000-2020 to 192.168.0.5.

To use this method, you’ll have to get the lab setup and started (but NO console sessions) and telnet from your remote site to x.x.x.x:2000 or x.x.x.x:2001 etc to access the console of each router. This method is best used in conjunction with one of the above.

Tip:Right click on a router ont he GNS3 window and select Change Console port to see what the current console port is! Hey, Thanks for the thorough explanation. Sorry I didn’t explained myself better. I am able to remote to my machine, and also I am familiar with port forwarding. Basically, I would like to Telnet to my GNS3 Labs from outside the network. Since you mentioned that I need to forward port 2000 or 2001 my question would be, Is there anything that I need to do within the GNS3 Lab for this to workbasically this is what I would do, please tell me what I am missing 1. Open ports 2000 or 2001 on my router 2.

Assign a static 192.168.x.x to my VM Ubuntu image (I usually do bridge with a second physical NIC) 3. Configure a Lab in GNS3 and keep all my routers up and running (Live) Now from outside the network I would Telnet to my Home GNS3 Lab using my external IP plus the open port, right? Example: 140.16.x.x:2000?? Kishore – I do hope to add some ASA examples, and maybe a microcore host when I get a chance. I’m working closely with mirshni (VPCS developer) to get a new improved version of VPCs. However, I’m not intending to get into Junos just yet.

My main objective in creating this VM is to help CCNA students, and in an image that I can still fit on a single DVD. However, there is no reason why anyone else can’t add these things themselves.

There are many “How To” articles and other advice on the GNS3 forum at gns3.net (do a google search for site:gns3.net howto asa). If anyone can update the image and send me the details, I’d be happy to include it. Definitely a great package. I wouldn’t complain about the size if you were able to bundle in the ASA & PIX stuff too. 🙂 Anyway, in part 5 of the installation section, there’s a little warning about adding/changing the IOS image. Just wanted to share that I unzipped a 7200 image & put it in /opt/GNS3/IOS and it has booted up fine. Even used Wireshark to capture a few packets running between the 7200 & 3725 just to verify that as well.

Didn’t do anything fancy, just like I ripped off the shrink wrap from a SW program, installed it, and everything just worked. Again, real nice work Chris. Kenny – there is no reason that you can’t load any of the supported IOS images into the /opt/GNS3/IOS directory and then use them in GNS3 – the bit in part 5 “I don’t have the recommended C3725 image, but have another c3725 image or and image for a 2600 or 2691” is about getting another image to work with all of the prepared Labs and Exercises – if you have JUST a 7200 image installed, the Labs/Exercises won’t work without modification. You need a c3725, 2600 or 2691 image because the Labs/Exercises all assume that there is are f0/0 and f0/1 interfaces, and in some cases an NM-16ESW module installed in slot 1 – which can’t be done on a 7200! Re the ASA and PIX stuff – I’d love to find the time to add some more, but like the 7200, there is no reason why you couldn’t add an ASA image and get it to work (you might need to follow a couple of the tutorials on to get the ASA image working though. I have tested this using OS X as the host OS (running VMware Fusion) and using WinXP as the host OS (using VMware Player).

I have not tested using Ubuntu as the host OS. However, I have seen the problem you describe and have had to make sure that: 1. Your host OS has an active LAN connection ie eth0/en0/Local Area Connection (Linux/OS X/Windows) – this means you’ll probably have to plug it into a hub or switch.

Give it an IP address of 10.10.10.6/29 and a default gateway of 10.10.10.1 2. Make sure your FIRST VMWare network adapter (GNS3 Workbench-Ubuntu) is eth0 (If not, run the script ot restore eth0 next reboot in the READMEs & Scripts folder) 3. Make sure your VMWare network adapter (GNS3 Workbench-Ubuntu) eth0 adapter is linked to your host PC’s ethernet connection (eth0/en0/Local Area Connection).

To check this: From VMware Fusion: Click Virtual Machine->Network Adapter->Network Adapter Settings From VMWare Player: Virtual Machine->Removable Devices->Network Adapter->Settings – On Hardware Tab, Check the FIRST network Adapter is set to Bridged Mode From VMWare Workstation: (Don’t know – can anyone help?) I have also had problems where the host OS has multiple adapters – most notably my MacBook Pro loves to get confused about whether the VMWare adapter is linked to my Ethernet adapter or my AIrport (WiFi) adapter, and so I have to turn off my WiFI so that it really does link en0 to eth0. So in short – if you have multiple adapters in your host machine, you may need to disable some. I have also seen this problem with VMware Player – and with VMware player, if you have multiple adapters it is very hard to edit the actual adapter settings – you have to run vmnetcfg.exe (see this page for help.

In-case you can’t use the VMWare tools. Because this is linux and the kernel will boot and detect pretty much any hardware at startup (unlike Windows, which will typically blue screen on different hardware) I’ve done the following in the past: 1. Boot GNS3-workbench VM with an Ubuntu live CD mounted 2.

Use the DD command to take a bit-copy of the VM HDD, mount and copy to a network share 3. Create a new ESXi machine, boot with an Ubuntu live CD mounted 4. Mount the network share and use the DD command to restore the bit-copy VM HDD to your new VM Hope this helps 🙂. There is a performance hit, but I haven’t done too many calculations – I was more interested in getting a “complete as possible” package together. If you have the recommended IOS, the labs have a good idle-pc value and depending on the host machine’s power you can run all the labs happily.

Eg – on my MacBook Pro (8 GB RAM) I can run a GNS3 WorkBench lab with 6 routers quite happily. On an XP machine with 1.5GB RAM – forget it! Being loaded in a Virtual Machine also adds a performance hit too – again on my PC I can run GNS3 topologies with 15 routers quite happily, but I doubt it would run so well on the Ubuntu VM (although I haven’t actually tried it).
