When I was doing the configuration for section 4.1 in lab4, after I type "zebra -d -f /home/lca2/Desktop/lab4/configs/zebra r1.cfg -i /home/lca2/Desktop/lab4/run/zebra r1.pid -z /home/lca2/Desktop/lab4/run/frr r1.api -u root -k", it shows "privs_init: could not setgroups, operation not permitted". After searching, I still not find solution for similar problems on the Internet. Any idea on how to solve this problem?
Thanks for your help
I find the way to solve this problem, but it still shows a warning:"ZEBRA : Disabling MPLS support(no kernel support)". What exactly does this mean? Will it affect the later part of the lab?
Hello,
I am working in a copy at /home/lca2/Desktop/lab4, and I have the same error (privs_init: could not setgroups, operation not permitted.) I tried the steps described by Alaeddine, but I can't manage to solve it. How did you solve this problem ?
My problem is that I write the command in a wrong place, the command should be in the window of mininet nodes(for example, r1, r2 and so on). If this is not the problem with you, then I think it can be solved with "sudo".
Are you working on the shared folder, or making a symbolic link toward the shared folder? if this is the case, please copy the lab4 on the Desktop and DO NOT work on the shared folder.
Good luck!
Alaeddine
I am now working on the Desktop, but still have the warning information.
kill all zebra /ospfd processes (command provided in the pdf), clean the mininet and restart again the work on the lab...
I have killed all zebra processes, clean the mininet and restart, but there is still this warning information: ZEBRA : Disabling MPLS support(no kernel support).
that is perfect, you can ignore this warning!
Thanks very much for your help!
