I'm just wondering if there are any commands that can be issued directly to a dns server by telnetting to it on 53. For example, you can telnet to a smtp/pop server and do anything, you can telnet to a web server and view pages....is it possible to do something like this on a dns server?

thanks in advance

yes, just read the protocol and you can send whatever commands to any port you wish. A better tool is nslookup on *nix or winblows.

in fact this is exactly how most TCP applications work, they just simply send commands and get responses, DNS might be a little trickier though because it is not session based. why do you think hacking is so relatively easy?
