Hello:
I am trying to follow the RHEL virtualization guide to set up a bridge on a system running CentOS 5.4.
I copied my ifcfg-eth0 to ifcfg-eth0:1 and set its content to this:
DEVICE=eth0:1 HWADDR=[The MAC address from eth0] ONBOOT=yes BRIDGE=br1
I then created ifcfg-br1 with this content:
DEVICE=br1 TYPE=Bridge BOOTPROTO=static BROADCAST=192.168.2.255 IPADDR=192.168.2.202 NETMASK=255.255.255.0 NETWORK=192.168.2.0 ONBOOT=yes DELAY=0
When I do service network restart, I get this error:
error in ifcfg-eth0:1: didn't specify device or ipaddr
I specified the device so it looks like it wants an IP address but that is contrary to what I am reading on the Internet.
Any ideas what went wrong?
Thanks, Neil

I did some more reading on the Internet and it looks like I am supposed to set up the bridge on eth0 and configure the bridge with the IP address of the host.
So, I removed ifcfg-eth0:1 and changed ifcfg-eth0 to this: DEVICE=eth0 HWADDR=[The MAC address] ONBOOT=yes BRIDGE=br0
I removed ifcfg-br1 and created ifcfg-br0 with this content: DEVICE=br0 TYPE=Bridge BOOTPROTO=static BROADCAST=192.168.2.255 IPADDR=192.168.2.200 NETMASK=255.255.255.0 NETWORK=192.168.2.0 ONBOOT=yes DELAY=0
I don't get any errors when I do service network restart but now I can't ssh to the host using the 192.168.2.200 IP address.
I also tried setting these values in /etc/sysctl.conf:
net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-arptables = 0
net.ipv4.ip_forward = 1
and rebooting the machine. That did not help.
Any ideas?
Thanks, Neil

Actually, this worked. I am able to SSH to the box on the 192.168.2.200 IP address. I had a typo in my ssh command. Sorry for any confusion.

Are you using the "leaked" copy of 5.4 or is it showing on some of the mirrors now?

I downloaded the DVD iso using the torrent file from one of the mirrors showing it.
