Remote Login Security Settings

[Zheng Wang]

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.
