Shalom,

Externally you can run a portscan.

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

Do you know the name of this program?
How can i close ftp for exemple?

[Torsten. · Accepted solution]

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.

you may run
#netswtat -an|more
to see which ports are opened or extablished.or you can run tcpdump to see the which ports are open.
