Recently we had a switch go down in the school, so the our tech guy had
to take the schools one out of my room and I have to use an older
donated one. Since then I have run into a small problem.
First I want to appogize for some of the missing details, I forgot to
write everything down that I needed before I left school. It is
graduation night, and I needed to get home, so I could get back :-)
The switch I am now using is an older Cysco switch. One 100MB port (for
server) and 24 10MB port for the terminal. I use 7 of the 24 ports.
The switch is a Catalyst (sp??) model, and I do not have the necessary
wires or information to change any of the current settings. Almost all
of the terminals are using 10MB NICs, so when we made the trade, I
really did not thing there would be much of a slow down, even though the
schools switch was all 100MB ports. But there where some major
slowdowns. When I checked the logs, there was a lot of crap repeated
over and over again, all starting with something about the duplex
setting on eth0, the card that connects to the switch.
After some research, I found that if removed the module, then ran
'insmod 3c59x debug=1 options=4 full_duplex=1' everthing worked fine
again. Unfortunatly, this affects both NICs, the onboard eth1 and the
PCI card eth0, and I do not know what kind of crazyness this may be
causing to the schools network. I can't change either of the cards
since one is on-board and school only has one kind of PCI NICs I also
do not want to have to go thought the process evert time I restart the
server. So I edited the one line in '/etc/modules.conf' file to say
'alias eth0 3c59x debug=1 options=4 full_duplex=1' thinking that would
work, but it didn't.
So at this point I am lost. Where can I but those options so that it
works on boot-up, but does not mess with eth1?
