GNS3 version 2.2.13

by Brent Stewart on Monday, Sep 7, 2020

GNS3 2.2.13 dropped Friday (9/4). The new version doesn’t make any changes to the GUI, but fixes a bug that surfaced when using a Qemu device. It also includes Beta 3 of the Web-UI. GNS3 WebUI

Should you upgrade?

For “production” software, I recommend upgrading to get security fixes or because there is a bug-fix or enhancement that you need. This version doesn’t seem to include a security fix, and the features aren’t things I use heavily so it may be optional. That said, the Web-UI is coming along nicely. In my initial testing, I’m able to add a node to a topology, add links, and manage things from the webpage. It looks like this would make it easy to collaborate with others on a shared topology. I can also envision using this as my sole access to GNS3. This is marked “beta”, but it seems to be in good shape. I definitely suggest you start evaluating it. If you do find a bug, be sure to log an issue on the GNS3 Github repository.

I have run into issues before that affected my ability to run GNS3 and took me a day or so to sort out (at least once was because I upgraded my OS, not because of GNS3). If you have ongoing work that depends on GNS3, hold off until you have a little slack in your schedule. One way to evaluate the risk is to look at the GNS3 community forum to see if there are posts about the new version.

My personal experience with GNS3 has been that most upgrades go without a hitch. I usually just go for it, but I’m not typically dependent on GNS3 from day to day. Note that gns3-gui and gns3-server have to be the exact same version. If for some reason you upgrade one, you either have to roll back or upgrade the other.

GNS3 Server Upgrade

How do you upgrade?

On Windows, just download the executable and run it. On Ubuntu, sudo apt upgrade. If you have a server VM (and I recommend it), start by getting a snapshot of your current server. I once had a server upgrade go poorly that resulted in rebuilding my VM, so this is a realistic risk. After that, log into the server and you can kick-off the upgrade from the menu.
