Renaming eth1 to eth0

jonnyhashem · 01-13-2006, 02:14 AM

Hi:
I had 2 ethernet cards on my system external(eth0) and internal card(eth1), then i removed the external card(eth0) and the internal one still named by eth1 ,so i swapped the 2 mac address in /etc/iftab and its done internal card (eth1) named by eth0 ,but the problem is internet didnt came up again on eth0 despite i configured the connection on eth0.
i did ifconfig and here what i had :

[root@localhost root]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:0C:F11:3E:95
inet addr:195.112.XXX.XXX Bcast:195.112.XXX.XXX Mask:255.255.XXX.XXX
inet6 addr: fe80::20c:f1ff:fed1:3e95/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:6026 (5.8 Kb)
Base address:0xd9c0 Memory:fe9e0000-fea00000

It taked the ip address and everything but internet didnt came up,so whats the problem here?

Can't you ping anything? not even the gateway or another node in the network?

which distro do you use?

cheers

Hi:

Code:

root@linuxbox:~# netstat -r
root@linuxbox:~# cat /etc/resolv.conf
root@linuxbox:~# traceroute 64.179.4.149

post the results of those, should help narrow down the problem some more.

Maybe your isp only accepts your old MAC address, since you have removed a card your MAC address has changed. Check with your ISP.

And for pk21 question , The internet is already now on internal card (eth1) and its working fine , but what i want is to change the name of internal card from eth1 to eth0.

Then isnt the only thing you need adjusting your /etc/modules.conf?

jonnyhashem · 01-16-2006, 03:06 AM

HI:
I have checked /etc/modules.conf , and i didnt find anything.

xstefanox · 01-16-2006, 04:54 AM

Configure your both cards in the /etc/sysconfig/network-scripts/ifcfg-ethX (Where "X" is the number of your network card give by the "dmesg" command). If there's not one for your card, create it, following the rules in that other files.

Make sure that the modules are up (But since the "dmesg" command shows both cards, there's no worry about that).

Since you're connecting through ADSL or something like it, you could be blocked by your ISP, just like pl21 said, so you should confirm this information, but first you should try to configure your connection again with adsl-setup (Or something like it. I'm not a Mandrake user, sorry).
