    " In many Unix operating systems the network devices have
appearances in the /dev directory. This is not so in Linux. In Linux
the network devices are created dynamically in software and do not
require device files to be present.

  In the majority of cases the network device is automatically created
  by the device driver while it is initializing and has located your
  hardware. For example, the ethernet device driver creates eth[0..n]
  interfaces sequentially as it locates your ethernet hardware. The
  first ethernet card found becomes eth0, the second eth1 etc."

This was quoted from NET-3-HOWTO in the /doc/HOWTO directory of my RH
6.0 Install cdrom.
   You can see the settings for configured ethernet devices in the
/proc/net/dev 'pseudo file.' Or, do:
   
            ifconfig <enter>

Read 'man ifconfig' for more info.
