Is that all? What's up with the lo(opback) interface?

Ah, there it is:

$ ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:11:2f:be:4b:ba
inet addr:192.168.0.100 Bcast:192.168.0.255 Mask:255.255.255.0

Is the 'lo' normal? I never actually look into its output -- was just
making sure the lo was there...

thanks

This is what a normal "lo" looks like:

$ /sbin/ifconfig lo
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
