Bind not listening?

[Marc.Thach at radianz.com]

netstat -na will tell you if there's a listener on the port.
Are you running any filtering software (like ipchains or ipfilter) on the
same server?
If you sniff the wire, what do you see when you telnet to port 53, do you
get a complete 3-way handshake?

Even from localhost I can't open port 53.

[root at naboo /etc]# hostname; domainname; ifconfig -a | grep 'inet addr'
naboo
swsim.com
          inet addr:66.12.147.134  Bcast:66.12.147.255  Mask:255.255.255.0
          inet addr:127.0.0.1  Mask:255.0.0.0

[root at naboo /etc]# telnet localhost 53
Trying 127.0.0.1...

[root at naboo /etc]# telnet 66.12.147.134 53
Trying 66.12.147.134...

Thanks!
