Eth1 turn off by itself after reboot

Hi,

Recently we discovered the eth1 of one of the server turn off by itself when the system reboot. Could someone please advise how to fix it?

Thanks

Well, indeed everything should turn off when you reboot your server ...

Seems like you mean: "It doesn't come up again after reboot."

Probably you simply haven't configured it to get an IP address and so an at system startup. Have a look at your system's documentation regarding startup and networking.

Sorry, what I meant was, after the system reboot. The eth1 was down, although it has the static ip configured and we need to manually bring up the eth1. Please advise how to fix it.

Make sure you have startup file properly configured. Usually in RedHat we give ONBOOT=y in /etc/sysconfig/network-scripts/ifcfg-ethX. Other vendor may have different options. You can use "Kudzu" or "netconfig" tool.
Also make sure you have eth1 module mentioned in /etc/modprobe.conf or /etc/modules.conf (as per kernel version 2.6 or 2.4 resp)

thanks for the info. :b:
