Very Computer

Hi,

I added a second network card to my Linux server, and my original card
stopped working.

The old card is a 3com 3c509, and the new card is a 3c900.

Linux recognized the new card, but I can't see it in ifconfig.

In netconf, all of my settings look right for the old card, but I can't talk
to the network.

Any suggestions?

Thanks,

Brent

Brent,

Make sure that you don't have a standard DHCP script starting as part of
your boot up process. For some weird reason, the way those guys work is to
try to set up DHCP clients on ALL your cards. It totally disables one or
more additional NICs you may have.

I wrote a little script containing the DHCP client setup (it's a one-liner;
see DHCP man page) and I only execute it after I boot up.

Good luck!
Daniel

Make sure that the drivers for the 3c900 are all set up correctly including
the irq setting. If linux cannot properly find the 3c900, the 3c509 will not
work. This was my problem with these two cards under Mandrake Linux.

Did you configure the new card? If not, then apparently what used
to be your (only NIC) eth0, is now eth1 and possibly even the drier
for it is no loaded. In /etc/conf.modules you'll need something like
--
alias eth0 smc-ultra
options smc-ultra irq=11 io=0x340
alias eth1 3c59x
alias eth2 3c59x
--
with appropriate options and module names for your cards.

After that, you may assign addresses, etc. to both cards.

HTH,
