I dont quite understand why you need to switch, you could just run everything off eth1, but anyway,
I would suggest looking in your bios and either disabling the onboard NIC, or changing the PCI probe order eg if its says first-last change it to last-first or what ever syntax your bios uses. However Its most likely that the onboard can simply be disabled in the bios. regards Steven -----Original Message----- From: Andrei Badea [mailto:[EMAIL PROTECTED] Sent: Friday, 8 October 2004 9:55 a.m. To: Debian User List Subject: Switching between two network cards Hello all, this is not quite a Debian related problem (except that I'm running sid), but anyway... I've got two network cards: one integrated on my motherboard (uses the sk98lin driver) and a PCI card (fealnx driver). Both drivers are compiled as modules and upon startup I'm loading only fealnx via /etc/modules (I'm not loading sk98lin at all). The network runs fine. After my system starts, I want to switch to the other network card (the sk98lin one), but I only want its module loaded, so I do: ifdown eth0 rmmod fealnx modprobe sk98lin ifup eth0 Messages in dmesg say the network is up and running. But it isn't, it seems I can't ping nor make net connections. However, when I (for example) run a ping and look at the LEDs on the card, I see them bliking in the "ping" way. I can also see the echo request and reply packets in tcpdump. But ping doesn't get them and reports 100% loss. If I unload sk98lin and reload fealnx, the net works fine. Now comes the interesting part: if I put sk98lin in /etc/modules instead of fealnx and restart, the net comes up. Only this time I can't switch to fealnx. This shows both the cards are working. I thought this was caused by iptables settings, so after loading the other module I rerun the script which setups my firewall rules. Didn't help. I'm running Debian sid with self-compiled kernel 2.6.7. Any ideas why this is happening? Not that is it important, as my net is running with any of the cards if I restart, I'm just curious. However, I'd like to point out that I don't want both modules to be loaded. I want to be able to unload the running one and load another without having to restart. Thanks in advance!
