I am constructing a list of network interfaces to monitor based on the contents of /proc/net/dev. But I am getting some bogus interfaces in the list:


Where do those come from?

They also show up in /sys/class/net/:

# ls -1 /sys/class/net/

For now, I think I'll just ignore anything starting with __tmp, but I'd like to know what they are and where they come from.

This is on a recompiled CentOS 5.3 kernel: 2.6.18-128.7.1.el5.tvh.7PAE #1 SMP PREEMPT

This appears to be a bug with CentOS and broadcom drivers, detailed here:

Most people seem to require a

modprobe -r *drivername*
modprobe *drivername*

or even a reboot (arg) to fix. The link also has suggestions of other workarounds.
