GEN003850 - The telnet daemon must not be running.

Information

The telnet daemon provides a typically unencrypted remote access service which does not provide for the confidentiality and integrity of user passwords or the remote session. If a privileged user were to log on using this service, the privileged user password could be compromised.

Solution

Edit the /etc/inetd.conf file and comment out the telnet line.
Reload the inetd process.
# refresh -s inetd
