Telnet test for DNS
Hi,
I would like to test a DNS server the same way that I test HTTP, POP, and SMTP servers. For the latter three, I telnet to the server over the proper port, type my request, and press [enter].
For example:
$ telnet treehouse 110
Escape character is '^]'.
+OK POP3 treehouse 2004.89 server ready
user bryanh
+OK User name accepted, password please
pass johngalt
+OK Mailbox open, 35226 messages
quit
+OK Sayonara
Connection closed by foreign host.
Can you tell me how to do this for DNS? I have tried the following but it does not work(i.e. I don't know the commands) and I always have to type [control]-] to quit telnet:
telnet nameserver 53
Trying <ip address>...
Connected to ns.
Escape character is '^]'.
google.com
quit
^]
telnet>
^]
telnet> quit
Connection closed.
Any help is greatly appreciated!
