I would give netcat a try. Using it with the -p flag like this: $nc -p 53 <ip> <destination port>should allow you to connect to any destination port using 53 as a source port. It also has a variety of other functions that would probably prove to be useful for you, so I would definately give it a shot.

Hi list, I'm pen-testing a system and with a normal "nmap -sS" I get no response. If I change the source port I could get through to the system, as you can see. 21/tcp open ftp 80/tcp open http 88/tcp open kerberos-sec 135/tcp open msrpc 389/tcp open ldap 443/tcp open https 464/tcp open kpasswd5 593/tcp open http-rpc-epmap 636/tcp open ldapssl 1026/tcp open LSA-or-nterm 1029/tcp open ms-lsa 1033/tcp open netinfo 1720/tcp open H.323/Q.931 1723/tcp open pptp 3268/tcp open globalcatLDAP 3269/tcp open globalcatLDAPssl 3372/tcp open msdtc 3389/tcp open ms-term-serv 6101/tcp open VeritasBackupExec 6106/tcp open isdninfo 8080/tcp filtered http-proxy 10000/tcp open snet-sensor-mgmt Is there a way, how I can establish a connection using source port 53? Thanks,Chris
