[one-users] can not create VLAN network model - sudoer & path need to change?

[Jaime Melis]

Hi Nicolas,

are you still experiencing this? Answering your question the proper way to
enable permissions is via sudo... so there might just be something a bit
wrong.
can you try the following:

oneadmin at onhost02:~$ sudo /sbin/vconfig add eth0 100

cheers,
Jaime
