Shalom,

Externally you can run a portscan.

You can run nmap from a Linux box or even install the same program on HP-UX.

When is a port open?

If "somebody" is listening to that port and waits for incoming connections.

Regarding ftp - this is started by the inetd - to disable edit the /etc/inetd.conf file and disable the ftp line. Now re-read the inetd config

# inetd -c

To secure your system you can also use bastille.

Zenus,

Like Torsten said you can disable the ftp in /etc/inet.conf. You will need some other file transfer protocal if you want to copy files to other server. You can use SFTP if you have ssh installed.

to see which ports are opened or extablished.or you can run tcpdump to see the which ports are open.
