laptop dhcp fails on severn

[sean darcy]

I'm  running a laptop with 2 pcmcia network cards on severn. One card ( A ) 
is connected to a cable modem - optimum online - the other ( B ) to the lan. 
ool uses dhcp, so A is set to uses dhcp. All worked great, until severn.

dhcp no longer works.  I've switched the cards. Both work on the lan with 
static ip addresses. I've flushed iptables. I even brought in another 
laptop. Same result. But...if I connect ool directly to a severn 
workstation, it works fine.  So it's only laptops.

Something's screwed up. Don't think  it's dhclient or dhcpd - tried both.  
Here's a snippet from ethereal of traffic over the card. It's sending out 
discovers and getting back offers. But it doesn't seem to see them. Is 
dhclient responsible for seeing them? Since the workstation had the same 
dhclient rpm, I assume it's a network script problem related to pcmcia.

Does anyone have a pcmcia network card that works with dhcp under severn?

I sure don't.

thanks for any help

For whatever it's worth, I have a FC-0.95 (Severn3) laptop, updated to
current rawhide contents, on which PCMCIA NIC works fine w/DHCP. The NIC
is a Xircom IIps (16-bit).

First...are you sure the correct drivers are loading (use lsmod to 
check.) Be sure to rule out networking problems. Have you checked your 
routing table (use 'netstat -nr')? Can the card see the default gateway 
that the dhcp server is offering? Clearly, with 2 different cards on 2 
different networks, you are going to have a complex routing table.

I wonder if your problem might also be affected by the order in which 
the runlevel startup scripts in /etc/rc.d/* execute. You probably want 
to bring up pcmcia, then the card needing dhcp (eth0?), then the second 
network card (eth1?), then the network configuration script at boot 
time. If the order that the scripts execute has changed between major 
releases, as they have here, then you could be affected. I'd carefully 
check to see which scripts are executing and whether the order and 
timing of them is what you need.
