What does your log say when you give the command "service named restart"? /var/log/messages or /var/log/syslog
These are contents of /var/log/messages =>
Nov 2 20:12:51 ns1 named[4702]: listening on IPv4 interface lo, 127.0.0.1#53 Nov 2 20:12:51 ns1 named[4702]: listening on IPv4 interface eth0, 192.168.1.162#53 Nov 2 20:12:51 ns1 named[4702]: command channel listening on 127.0.0.1#953 Nov 2 20:12:51 ns1 named[4702]: zone 0.0.127.in-addr.arpa/IN: loaded serial 1997022700 Nov 2 20:12:51 ns1 named: named startup succeeded Nov 2 20:12:51 ns1 named[4702]: zone 1.168.192.in-addr.arpa/IN: loaded serial 2001062501 Nov 2 20:12:51 ns1 named[4702]: zone abcd.com/IN: loaded serial 2001062501 Nov 2 20:12:51 ns1 named[4702]: zone abcd.com/IN: loaded serial 2001062501 Nov 2 20:12:51 ns1 named[4702]: zone localhost/IN: loaded serial 42 Nov 2 20:12:51 ns1 named[4702]: running
