Collisions with Intel EtherExpress Pro 100B
Fri Aug 6 18:42:04 1999
Hi. I hope this question is not a repeat or just something stupid I
have missed, but I have been fighting this collision problem for days
What happens is this:
I have a linux machine running RedHat 5.2 with an Intel EtherExpress Pro
100B in it. I am using the updated eepro100.c (v1.08) which I
downloaded from the cesdis.gsfc.nasa.gov site. It is connected to a hub
along with one of our company's embedded PC boards which has an
integrated SMC9194 chip. I am attempting to bring Linux up on this
board but keep running into this network problem.
Whenever I transfer files between the two computers I get massive
collisions. I have tried a million configurations to get rid of the
problem. I have tried the boards under Windows and Linux. I have tried
removing the SMC board. The only way I can get rid of the collisions is
under one setup: running the EEPro under Windows and using the windows
FTP client to transfer files from the SMC computer to the Windows
computer. However, if I transfer files the other way (from the windows
computer to the SMC one) I still get collisions.
All other configurations result in collisions. Even two computers
running Linux, each with an EEPro in it gives me collisions. I have
tried a different hub and new cables. Nothing seems to work.
I tried playing with the 10/100 settings and the Duplex settings.
Figuring that the hub only ran at 10Mbits, I forced the EEPro to run at
10 using the driver options, and made sure both cards were half-duplex.
Am I just missing something? Any help would be greatly appreciated.
