Hi:
On a RedHat 9 host, I establish a VPN connection (Cisco VPN Client 4.6.02) to work's network. After exiting from VPN, Redhat DNS setting does not change back to the original ones.
Thanks in advance.

Both file /etc/resolv.conf.vpnbackup and /etc/resolv.conf exist.

Somehow, file /etc/resolv.conf.vpnbackup exists after VPN is disconnected. It holds DNS setting inherits from DNS. I delete this resolv.conf.vpnbackup file and things back to normal now.
