I was so irritated to see this "206 Unable to create UDP NIO" error while trying to open any saved topology. The error looks like below, I went through a lot of forums to trace out the root cause of this issue. I found the solution, we will discuss about this post. I happened to receive this error on Windows 8 machine & this could occur in any platform. Follow the below steps to solve the same. Changing UDP Port Number First try to change the UDP port number to a new value as shown below. Here, I have changed to 10001 from 10000. This might help you to open your topology file. But for me changing udp port number also did not help. These port numbers might be used by some other application in your PC. Editing topology file The UDP port number in GNS3 Preference tab should be same as your topology file configuration. For example, if you have configured 10001 as your Base UDP in GNS3 tool, your topology file also should have the same value. The below images illustrate the output of netstat -an command in command prompt. You can see that 10000 UDP por

I am running ubuntu 8.10 and started by just installing the default one that is included in the repositories. It did not save so I installed the update (GNS3 0.6) to try http://forum.ine.com/forums/t/4636.aspx to fix it, and it still did not work. I have been through 3 tutorials, the official GNS3 one, another pdf I found somewhere (which I can no longer find), and one from this site. I have windows 7 searched for this error and found answers but nothing so far has fixed it. I have changed the directory I install it in, I have deleted all remanents of GNS3 that I can find and started over, and still the same error over and over. Any idea? I will post anything you need me to, so just ask. Thanks a lot Back to top canabalJoined: 16 Jan 2009Posts: 2 Posted: Fri Jan 16, 2009 6:29 unable to create am Post subject: Ok, I seem to have it working. But in order to get it going, I must go into the options and press the test button in the dynamips menu. Which in and of itself is a bit of a pain, but the bigger pain is, if I forget to press the test button, when I go to save it will obviously not work... so I go and press the test button and everything gets erased. Any idea? Oh I also have some strange errors on the 1st 2 routers I put in. the 1st will always say: +OK POP3 thats cool man and the 2nd will sometimes say: 220 WebMail ESMTP Not a big deal, but I just delete the 2 routers and put in new ones and it is fine from there. Thanks again. Back to top busycityJoined: 20 Jun 2009Posts: 1 Posted: Sat Jun 20, 2009 3:40 am Post subject: I had the same problem before. Now I worked out. You have to save your running config to start config before you can export all the configs.
