Network traffic reports as zero bytes
Just installed Ubuntu Server 13.10. I'm in the middle of setting up some scripts that help me monitoring the server's activity. Now I find that the network traffic stays at zero bytes.
Here's what I mean: /proc/net/dev says:
@boson:~ $ cat /proc/net/dev
Inter-| Receive | Transmit
face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed

lo: 1184 16 0 0 0 0 0 0 1184 16 0 0 0 0 0 0
For those wondering:

Any clues on how to get the counters working is welcome.
