Re: DNS name resolution not working

 

   Interesting discovery...

   As Rick suggested earlier, I decided to try switching to DHCP.  I edited
/etc/sysconfig/network-scripts/ifcfg-eth0 and set BOOTPROTO=dhcp and
commented out the IPADDRESS=, and rebooted.  And voila, DNS works.

   I really would like to use static IP for my local VM though...
