Re: Dynamin DNS updates from clients

I am trying to update DNS information of the clients in the DNS server

The clients have hostnames (that will not change ofcourse), but since

information?

Any help will be great in this regard.

Thanks to all.

This is usually a bad idea. It's easy to tell DHCP to assign specific MAC addresses to specific hostnames and IP addresses, with : otherwise, you have to mock with /etc/dhclient-eth0.conf, and put 'DHCP_HOSTNAME=$HOSTNAME' in your /etc/sysconfig/network-scripts/ifcfg-eth0 in order to get the RHEL machines.

The big problem of wandering IP addresses is wandering SSH and SSL keys. The second big problem is NFS, which gets quite unhappy if a server does not successfully disconnect its mounted directories and comes back up with a different IP address.
