How can I enable my eth0 to full Duplex mode and 100mbps speed

josh oshiro, Ravi Cheema,


Ok, I give this a shot even though I haven't touched a linux box in 
years. This information is directly realative to OpenBSD but might work 
on linux.
To initialize your interface in 100baseTX full-duplex mode you might 
use the ifconfig command like this:
#ifconfig <interface> media 100baseTX mediaopt full-duplex
Ofcourse if you want it to do this everythime the system starts you 
would would put it in a rc script somewhere. In OpenBSD that would 
be /etc/rc.local and in linux it is probably similar.
This advise may be null and void if your device driver does not fully 
support your network interface card becuase in this case it may not be 
possible to initialize your interface in the desired mode at all.
As a disclaimer, I have to say that many linux distrubution have 
alternate methods of doing things and that this advise may not apply to 
your brand of linux.
