I have observed this message several times:
[ERROR] can't open channel socket
[ERROR] initialization failed
which is very difficult to understand.
The errno message should help this to be a bit more explicit.
With this patch, in the case of wrong interface:
[ERROR] can't open channel socket: No such device
[ERROR] initialization failed
