Trouble receiving interface list.

Have some problems with the linux-agent. Can't get the interface list
from the agent.

On another system running same linux version it works, (the node running
the server). I've tried to change the polling node to itself, but it
won't work.

Another problem is receiving the list for the alias interfaces on linux 
boxes. Will this feature be supported soon? What about routing-table?
