network card installed correctly - doesn't work

[atzep]

I have installed a realtek 8139. With the setup-tool of my distribution I configured it with a static ip-adress,
I set routing with route add -net 192.168.10.0 netmask 255.255.255.0 eth0
and I can't ping another computer! (destination unreachable)

I tried different ethernet adapters (all with realtek nic) and different cables

I tried the same on another computer (same linux distribution) and all works fine!

I think it is problem with shared irq's! How can I fix it?

Has anybody another idea?

thx

When you load the module you can pass parameters to the kernel. Those are an option line in /etc/modules.conf.

also type "cat /proc/interupts" and see if there is a conflict.

If you see a conflict you can reboot and go to the system bios and "reserve" the irq for legacy, this will force the pci cards that are using that irq to get a different irq.

Try those.

Can you add a bit more info about the rest of you're network, IP addresses, topology etc. Also what distro are you running, what is the rest of the network, are there any firewalls running etc??

Hi!
My distro is a Suse Linux 8.2!
There are 2 more computers in the network, one with windows, one with linux, all connected to a fast ethernet switch!
IP-addresses are 192.168.25.x (1..3)
there is no firewall running!

there are no conflicts with shared irq's, so it must be another problem!

ifconfig says:
Protokoll:Ethernet Hardware Adresse 00:20:18:BA:0D:FD

Hi, if you're ipaddresses are in 192.168.25.x (1..3) then you're root setting should be

route add -net 192.168.25.0 netmask 255.255.255.0 eth0
instead of
route add -net 192.168.10.0 netmask 255.255.255.0 eth0
because you're netmask shows that the first three numbers are significant. Also when running a small network like you are you shouldn't need any route settings save for the gateway address for the internet. Flush the routing tables and try again. If it doesn;t work make sure that you aren't using crossover cables or connecting the straight cable to the crossover port in the switch (if such a thin exists on you're switch).

Hi!

Sorry that was my mistake. Writing the first posting I confused the IP-Addresses. The real address is 192.168.25.x
and the real route is set with route add -net 192.168.25.0 netmask 255.255.255.0 eth0
Actually I know that I don't need a route, but I try it.
I have no crossover cables and the switch realize if there is a crossover connected
