![]() Hi and I am sorry to bother you, but I was too optimistic about fixing my errors with GNS3. I tried to uninstall GNS3 and reinstall it eight different times completely, but the result would be a different error finally, at the last try, the original error showed up (the error had to do with the GNS3 server and the GNS3 VM being on different networks.) instead of trying one more time uninstalling GNS3 and then reinstalling it I did a quick Google search and found some article that mentions the GNS3 server and the GNS3 VM need to be on the same network, as soon as I change the network the GNS3 Server was on to the one the GNS3 VM was on all my problems went away, at least so far. I would find a solution that seemed to fix one error, but a different error would take its place. The problem didn’t lay with installing GNS3 on Linux but with the program not working as it should after everything was installed. I know many readers of this forum would say adapting a guide designed for Windows should be easily adapted to work on Linux well, the installation instructions were easy fortunately, the GNS3 community as installation instructions on their web site on how to install the GNS3 program and GNS3 server on all the major Linux operating systems. It was quite a challenge the reason it was challenging is THe instructions are for Windows only, and I had to figure out how to adapt the guide for Linux since Kubuntu is the only operating system on my computer, without knowing a lot about how Linux works. Meaning I was trying to get GNS3 Server and GNS3 VM to all run on the same machine. I followed a guide written by David Bombal on installing Cisco Virl appliances using Virtualbox as the hypervisor to host GNS3 VM. ![]() To that end, this post is about how I solved my first networking setback I have come across. Thanks, everyone, for the advice it has been beneficial.Īs promised, I am blogging about every networking discovery I find. ![]() I decided to post about my discovery that the RT-88U will provide Internet access without any other device needed, in case someone else is looking to replace Cincinnati Bell’s provided device with something else. Then ran the default setup program and followed the prompts. I set up the RT-88U by connecting the ethernet cable from the wall into the Wan port on the back of the RT-88U and turned it on. In other words, I have the ASUS RT-88U connected to the outlet provided by Cincinnati Bell, no other device between the ethernet cable and the RT-88U, and I didn’t have to call Cincinnati Bell to make any network changes on their end. I have been running the ASUS RT_AX88U for about six months, all without a modem. It is possible to replace Cincinnati Bell’s provided router with an ASUS RT-AX88U router. I have learned something interesting that I forgot to share in my previous posts. I included more information on how I have my Netgate SG-5100 is connected to the internet. Now let us test inter-vlan routing in this simple topology.You might want to reread the original post I just finished editing it. Now simply drag your IOUs to your working area and create your switching lab.Repeat step 9* for the Router IOU image.Under IOU image paste the location which you have copied from the image upload screen. Now under IOU devices, Click New->Next->Ok->Give a name(like Switch IOU).Next, goto GNS3 server->Remote server.Under path to IOURC put D:\GNS3 IOU\IOURC.txt (the location of IOURC.txt file). The full path will be shown after uploading is completed. Select the L2 and 元 IOU image one by one and click on the upload button.In my case it was: 192.168.56.101:8000/upload where 192.168.56.101 was the IP of the VM which was the Host-Only adapter of the Virtual Box instance. After it has started, you will note an IP address shown above the console screen.It may take a few moments to run at the first time. Make Sure you don’t have any older version of IOU installed in it. Let us now go through the step by step process to configure IOU in GNS3: ova file available on GNS3 Official Site)įor you to access them easily I am making all the “ rare files” available for you here : To configure IOU in GNS3 you will need the following files: If you want to know what is an IOU? Refer to this excellent article here else follow along… It has a special IOU feature which will let you emulate real Cisco Switch both L2 & 元 in GNS3 without any trouble. ![]() We all may have heard the saying GNS3 is great for practicing routing labs but switching Nah Nah!! Don’t underestimate the power of GNS3. ova for GNS3-IOU instead of pre configured VM.
