I studied the thread "Lost in Networking" linuxquestions.org/questions/history/253892 and I have a similar problem. Unfortunately I don't seem to be able to solve it with the given info. My particulars - Router: SMC Barricade 7004AWBR, address 192.168.2.1; computer with problem of not starting eth0 or seeing the router has a Soyo MB with on board LAN VIA VT6102 [Rhine-II] (rev 78); operating system is Mepis (all works fine in Win98SE), address assigned this computer by the router seems to be 192.168.2.21 and a Dell on the network running Mepis is 192.168.2.26 (I think I got these addresses in Windows). Both machines and router are set up dhcp

It seemed to work so well in the other post, but then I have no idea what most of it means. Any help would be appreciapted.

ror

as root try
dhcpcd eth0
(note dhcpcd not dhcpd)
failing that try
ifconfig eth0 192.168.2.2 netmask 255.255.255.0 up

If that works, add that to your rc.inet1 or rc.inet1.conf file (I forgot which and where it is, which is kinda sucky given I've had to post it's location 3 times this evening, damn being trapped on windows)

You need to be logged in as root to change the configuration but when you were logged in as root you did not assign eth0 an IP address.

Try again but logged in as root this time.
ifconfig eth0 192.168.2.21 netmask 255.255.255.0 up

Okie2003

Thanks for the quick replies. See the response I got:
root@18[rob]# dhcpcd eth0
bash: dhcpcd: command not found
root@18[rob]# dhcpcd eth0
bash: dhcpcd: command not found
root@18[rob]# ifconfig eth0 192.168.2.2 netmask 255.255.255.0 up
root@18[rob]#

Still unable to bring up eth0. Also tried Michaelk,s suggesting:
root@22[rob]# ifconfig eth0 192.168.2.21 netmask 255.255.255.0
root@22[rob]# ping 192.168.2.1
PING 192.168.2.1 (192.168.2.1): 56 data bytes

As you can see there was no response and still could not bring up eth0

ror

Can it ping it's own IP?

Is is sharing the same broadcast as the router?

The fact you don't have dhcpcd is worrying, what distribution are you using? perhaps you've a different set of net tools or something.

Okie2003

I am using Mepis. I am not sure what your are asking "can it ping it's own IP?" If this is what you meant:
rob@27[~]$ ping 192.168.2.21
PING 192.168.2.21 (192.168.2.21): 56 data bytes

The answer seems to be , no.

Not sure what sharing the same broadcast means. I have two computers wired to the router. They work fine in Win 98 and one (the other one) works fine in Linux running Mepis.

ror

if you can't even ping it's own IP then the problem definatly lies with ifconfig, try
ifconfig eth0 down
ifconfig eth0 192.168.2.21 netmask 255.255.255.0 up

if you still can't ping 192.168.2.21 after that, then something really weird is going wrong.

Can you ping 127.0.0.1?

michaelk

It is typical with linux that no response means the command compeleted successfully.

Check again to see if eth0 is being assigned an IP address.
ifconfig eth0

Check the output of dmesg. Maybe there is an error.
dmesg | grep eth0
and this command will check the link.

Thanks so much for your help. Wish I could be of more use. Here is what I have now.

Yes – BUT the system center still shows eth0 down and when I tried to communicate with my router with my web browser I can't and...

I was not sure if the last command needed to be run as root, so here it is:

Does the output of lsmod display the via-rhine module?

ror

odd that it's IP isn't showing on ifconfig even after you've just upped it with an addr.

Okie2003

I am not sure what it means, but here is the part of lsmod that I thought might apply:
nls_cp437 4608 1
via_rhine 14216 0

Thanks again for your time and your instruction.

The modules appear to be loading. However there are errors being reported via dmesg.

What kernel are you running?

Okie2003

kernel 2.6.7
