Mininet is completely broken #214730

Open autrimpo opened 1 year ago

autrimpo commented 1 year ago

Describe the bug

In its current state, Mininet is unusable. The wrapper does not work correctly - the mn executable can't find the mininet modules. Moreover, it seems that the version of openswitch in nixpkgs is not compatible: it calls the dpctl command, and even symlinking ovs-dpctl to dpctl does not work, as the they use e.g. deldp instead of the current del-dp. Going through Mininet sources and install scripts, it looks like they use v1.4?

Steps To Reproduce

Steps to reproduce the behavior:

  1. set programs.mininet.enable = true
  2. run sudo mn

I haven't used mininet in several years, do you want to become maintainer ?

autrimpo commented 1 year ago

I don't use mininet either, I was preparing some assignments for students and thought we could use it as part of that. Gave up when I ran into the issues above. So unfortunately, I do not have the experience or capacity to maintain it, but I'll be happy to share the ad-hoc fixes I made along the way in case anyone decides to pick it up.
