Hi all,

I have a CentOS 5.5 machine and would like to connect it to the internet via a Hawking L2 switch.
The Hawking L2 switch is already connected to a live network port on the wall and now all I have to do is connecting the machine to the L2 switch.

On the machine there are different network outlets all numbered with different numbers. How do I know which one I should connect to the L2 switch?

The ifconfig returns definitions for eth4, eth5 and eth6 so I tried connecting the cable to no. 4 and it didn't work, tried 5 and 6 and no luck and the machine still can't ping another machine which is inside the same network.

Could someone please shed some light on this please?

Thanks in advance

This works on Redhat and Fedora, so should work on centos:

configure all your /etc/sysconfig/network-scripts/ifcfg-eth* as explained in http://www.centos.org/docs/2/rhl-rg-...rkscripts.html
You should also mention the GATEWAY in here (the default route to the outside world) as explained here: http://www.centos.org/docs/5/html/De...nterfaces.html

then restart the network (/etc/init.d/network restart)

then in a terminal, run this:

then unplug and plug back each network cable of the server one by one. You should see a message appear with the ethernet interface name. Then you can add stickers on the ports and cables so you don't need to do that over and over.
