CentOS 5.7: How can DHCP automatically update /etc/hosts?

needsleep · 10-30-2011, 10:25 PM

The current ip address, as defined in /etc/hosts file, is no longer current with the DHCP clients table from the router. How can I tell Linux to update it? How can this be configured so that whenever DHCP renews the address, it will update /etc/hosts and any other file that has an address so affected?

Thanks,

If you're using DHCP, your /etc/hosts should just contain:

Code:

127.0.0.1       localhost.localdomain   localhost
::1             localhost6.localdomain6 localhost6
