Network bonding

Linux and Unix-Like Red Hat
1

Dear All ,

Very recently we have configured Network bonding in our Linux Server Redhat Linux 5.x.

After configuring , we restarted the network services , the link was down after that , we could not login in to the Server.

So after that , we logged in to console and tried to delete the bonding and enable eth0 interface which was before. But it was not working.

Now we are not able to login to the server using eth0 interface.

Please let us know what might be the issue.

Hi Jegaraman,

Please share the network related information. Given details are insufficient to guide.

#ifconfig -a
#ethtool eth0
#netstat -nr
#dmesg | grep eth
#lspci  | grep -i eth
#cat /etc/sysconfig/network-scripts/ifcfg-eth0

(output of ifcfg-bond0 if the file is present, assuming bond0 is your bond name)

Any typo will cause networking to fail. Restore your original configuration and start over. You can also do the following command as root to get your interface up temporarily...

ifconfig eth0 the.correct.server.ip netmask 255.255.correct.netmask

route add default gw the.correct.gateway.ip
