Remote Login Security Settings - AIX

Hi, We have a IBM SP system running AIX 5.1L and I am helping the setting up the system recently. My question is how to turn off the un-encrypted telnet service on the system. Every single user on this computer is using SSH client supported by the SSH server program on the SP machine. Is there a quick fix to reconfigure the AIX so that it no longer takes TCP request on port 23 and 21? Thanks for any help! Zheng...

    Default Remote Login Security Settings

    Hi,

    We have a IBM SP system running AIX 5.1L and I am helping the setting up the
    system recently. My question is how to turn off the un-encrypted telnet
    service on the system. Every single user on this computer is using SSH
    client supported by the SSH server program on the SP machine. Is there a
    quick fix to reconfigure the AIX so that it no longer takes TCP request on
    port 23 and 21?

    Thanks for any help!

    The same way you do it on pretty much all UNIXy systems on the
    planet: comment those services out of /etc/inetd.conf and restart
    inetd.

    vi /etc/inetd.conf, comment out ftp and telnet, save file, refresh -s inetd.
