[AG-TECH] Linux networking problems

[Kay Gunn]

Our switch is set to full-duplex 100MB (no autonegotiation).
I am forcing the cards to do full-duplex in /etc/conf.modules.

For the 3c59x card:
alias eth0 3c59x
options 3c59x options=204

For the EtherExpress Pro100:
alias eth0 eepro100
options eepro100 options=0,0,0x30

I have tried moving the servers to various different switch ports using
various different cables.  Results do not change.

As an added test, I just blew away the Redhat 7.1 install that was doing
ftp transfers of 11MB/sec.  I replaced it with the 1.0AG install.  It is
now doing ftp transfers of less than 3MB/sec.  Same hardware, same switch
port, same conf.modules/modules.conf setting to force fullduplex.

Is there a way I can check on a 6.2 box to tell what the eth card is
really running?  Redhat 7.x comes with the mii-tool utility, which will
tell you what your card is running, but I haven't been able to find this
for 6.2.  I can see by running multiple ifconfig -a eth0 commands over
time that I am not getting any errors or collisions, which is what I'd
expect with correctly negotiated fullduplex. However, I'm not sure how
reliable the info from ifconfig is.  I'm going to try to get our network
admin to look on the switch to see if he sees errors for this node.

Thanks alot for the replies so far.
