    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
