I've got a RH 7.2 install. I'm a newbie. In WinXP I can configure
the NIC "media" type between Auto/100BaseTX/100BaseTXFullDuplex/
10BaseT/10BaseTFullDuplex. I can't figure out how to do this in
RH 7.2. Any pointers appreciated. Thanks.

On Linux, you pass such things as options to the NIC driver. What the
option is called varies from one driver to the next. Usually, Linux
drivers default to Autonegotiate (and call the option you are looking
for speed or something like that), I urge you to leave it at
autonegotiate unless you really need to hard code it.

Sometimes you can do that, but not all drivers support it or support
it in a similar way.

The "generic" method is to use mii-diag or another program
specifically designed for your make and model of network card.

I agree with the recommendation (which I have removed) that you let
your NIC autonegotiate its speed unless you have an extremely good
reason not to. Fixed-speed NICs cause far more problems than you
might expect; at least, I found that to be the case when I had to do
it.

There is no reason other than curiosity over if a 800MB
file would travel faster between the 2 computers on this
little net I've put together in the last 2 weeks. I thought
with both set to auto I might only be getting 10MB lan
transfers and was interested to see if I locked it at 100MB
if the speed increased. But in reality, nothing important
would be accomplished. I appreciate the response and will
take your advice, since the complexity of the test seems
out of my league at this time.Thanks!

No reason other than curious for a comparison. Advice accepted.
Thanks!

For eepro100 driver, 100BaseTXFullDuplex is forced on using
options eepro100 options=0x30,0x30

in my modules.conf file. (Above forces two cards actually.)
Some old switches can not autonegotiate correctly with some cards and this
is needed.

You can find options using a proper google (groups) search or search from
appropriate kernel source file, like

/usr/src/linux/drivers/net/eepro100.c in my case.
