I have a ClarkConnect (CentOS based) box running as my home router on a RR connection. I had the DNS servers set up to use Google's DNS server. I want to change them back to the local DNS servers but I can't find an obvious/easy way to get those address short of a) reconfiguring the router's network to DHCP them (would rather not interrupt everyone) or b) calling their tech support (kill me now!).
Is there a command line tool/command I can use to query the DHCP server on the external NIC to see what DNS servers it would set me up with w/o munging my existing setup?
