Re: [CentOS] Can two machines in the same network have the same hostname with different IPs?

From: Indunil Jayasooriya indunil75@gmail.com

my task is to have 2 zimbra servers with mail.example.com with 2 ips 192.168.0.1 is the primary, I want to rsync /opt of this server to the other server 192.168.0.2. then, primary fails, I have a backup on the other server. no data lost.... This is what I want to achieve. but, NOT for any kind of ROUND ribbon DNS stuff..

On the server itself, as long as it is only in /etc/hosts, I think  you can (be sure to have hosts: files dns in nsswitch.conf). So you mean to manualy modify your DNS to switch from 192.168.0.1 to 192.168.0.2 if 192.168.0.1 is down? Maybe have a look at the Zimbra multi server install documentation.
