Description Jared Jones 2004-12-13 20:40:55 EST
Description of problem:
I have a RedHat-8.0 server/router/wap which has a subnet (
for my wired LAN and a subnet ( for my wireless LAN.  It
works for wired and wireless Windows clients.

On bootup, my prism54 PCMCIA wireless card has an incorrect routing
table for my network.  I can ping (server's wireless card
in Master mode).  I cannot ping (server's wired card), any
wired machine, nor the Internet.

The same routing table is setup after I do `ifdown eth0; ifup eth` at
the command line; in addition to the routing table, it gives
SIOCADDRT: Network is unreachable.  dhclient is unable to get a lease
due to no route being available.

Version-Release number of selected component (if applicable):

How reproducible:
Every time on bootup.  Every time on command line.

Steps to Reproduce:
1. Boot up machine.
2. OR
3. /sbin/ifdown eth0; /sbin/ifup eth0
Actual results:
`iwconfig` stuff is all correct (essid, wep key, etc.)
Routing table: * eth0 *   eth0

Expected results:
It should be able to ping the server's wired nic, other wired
machines, and the Internet.  The routing table should be setup
correctly, which would allow dhclient to work and get a lease.

Additional info:
I am able to work around this issue by manually setting up the routing
table.  Shouldn't ifup do this automatically?  Or is it because my
network is a special case?  Thanks!

ifdown eth0
iwconfig <all that stuff like essid, wep key, etc.>
route add eth0
route add default eth0
dhclient eth0


ifdown eth0
ifup eth0 (this adds route
route add eth0
route add default eth0
dhclient eth0

Your configuration has no default route as posted.

Note that Red Hat 8.0 Linux is EOL and is no longer supported.

My apologies I was not explicit in saying that my laptop is running
Fedora Core 3 and uses the prism54 pcmcia wireless adapter.  The
problem is not RH-8.  The problem is that /sbin/ifup on FC3 is not
setting up a default route.  It only adds  I have to
manually add and manually add the default route.

Shouldn't ifup do everything for me?  As it is now, I cannot boot with
my wireless pcmcia card working.  I need to hack more commands to make
it work.  Any help is appreciated, thanks!

What's your dhcp conf file look like?

You should probably set the network to pass the router for
whatever interface your server has on the network.
