Linux network tip

When trying to activate eth# in a Linux PC, one might get error message similar to "linux network Determining IP information for eth1 failed no link present check cable"

I found out one solution on the internet and it worked for me. Below is another copy of the solution.

Edit /etc/sysconfig/network-scripts/ifcfg-eth1, (when working with eth1)
#add following 3 lines at the bottom of the file:

check_link_down() {
  return 1;
}

Open terminal and issue command:

ifup eth1

It works on a Red Hat Linux under root account.
