I believe he's onto something there...routable addresses would be 172.16.254.81 thru 172.16.254.94 on 28 bits...and there's that pesky rule about having your gateway on the same subnet as the node. :) ------Original Message------ From: Eduardo Grosclaude Sender: centos-bounces@centos.org To: CentOS mailing list ReplyTo: CentOS mailing list Subject: Re: [CentOS] Bring up Networking in Single User Mode Sent: Oct 7, 2009 1:35 PM

Nate,

...

ifconfig ethX IP_ADDRESS netmask NETMASK route add default gw IP_OF_GATEWAY

OK, so I was correct,

I am doing

ifconfig eth0 172.16.254.80 netmask 255.255.255.240 route add default gw 172.16.254.1

I am getting Network is unreachable.

That's correct. Write down 80, 1 and 240 in binary. With a /28 mask, your IP address and your gateway are in different subnets.
