HI
i have just installed another NIC onto my linux machine (woody version). I assign an ip to it via editing /etc/network/interfaces and install driver via modconf command. When i restart the computer i can't see the new eth1 loaded. I try to use ifconfig eth1 up 192.168.50.126 netmask 255.255.255.0 command, and i got resource temperarily unavaliable. But the funny thing is , i can ping the 126 address from other computer in lan , there is no data loss.


Can anyone help me with this problem? Btw , our LAN use static IP and the driver for eth0 is epro100 and eth1 is sis900.

============below is the mesg i got when typing dmesg ==========

Thanks in advance

Try $ ping 192.168.50.(some real adress) -I eth1
if this work then it is OK

hmm i got bad interface adress 'eth1' if i type in the command you suggested. I got the same message if i type eth0. But it work if i replace eth1 with 192.168.50.126.

So, what is the problem? is it because that my 2 interace card can't connect to the same subnets?


Sorry, if it's a dump question, i just start to play around linux few day ago :P.

You can have as many connections from one box to any (or the same) subnets.

Remember that TCP/IP is the same on a Linux, Windows, or Mac [other OS insert here] box.

Start from the beginning:

1. Before putting in your second card, make sure your first ethernet card is working and doing what you want it to do.
2. Install your second nic. Boot the system.
3. Before making any changes to config files, run ifconfig (as root) on your second card (eth1):
# ifconfig up eth1 192.168.50.x <- replace IP address with the one you want it to have.
Note any error messages you might receive. If no messages then your hardware is most likely working.
4. Do:
# ping IP.Address -I eth1

If all is well then consider that it's working, and then set up your configuration files.

when i type in ping 192.168.50.real_ip -I eth1 , i got:
#bad interface address 'eth1'

Same result if i replace 'eth1' as 'eth0' which is the frist card and work perfectly well with my apache web server (my lan can browse from eth0's ip).

For step 3, i got "resource temperarily unavaliable" as mentioned on the first post of this thread.

any other thing i should try? I am pretty sure the 2nd card work flawlessly,coz i took it from other window machine.

Run this:

cat /proc/interrupts

See if it's possible the two nics may be mistakenly tied to the same IRQ.

Below is what i got from cat /proc/interrupts . It seems my eth1 , which use sis900 driver , is not even have irq assigned?

13: 1 XT-PIC fpu
14: 207331 XT-PIC ide0
15: 7 XT-PIC ide1

===============================

By the way, i type in lsmod , and find that my sis900 driver seems not in used. Does that mean i install a wrong driver? (i install sis900 coz there is such chip on my lan card)

was searching around and found the solution.... It seems the plug-and-play feature of bios causing the problem. I simply press DEL at computer reboot, then disable PnP. Everything work as champ

btw , anyone know what "SIOCSIFFLAGS" stand for(or its meaning)?

Not exactly sure, but I used to see it whenever I would try to configure that didn't exist or re-configure something like route add.
