Ubuntu or Debian

Just do the following will install openresolv to your system.

sudo apt-get install resolvconf

CentOS or Redhat

You need both openresolv (http://roy.marples.name/projects/openresolv) and a patch. The patch is generated by us, to make openresolv work with dhclient.

Note: to avoid direct overwriting to resolv.conf, please make sure that only "dhclient" program is actually called when changing DNS configuration (modifying resolv.conf file).
