Unix Tip #4658- December 12, 2023
LOCK DOWN TELNET OR FTP
When inbound access isn't required into
a system deny users Telnet or FTP access
do the following:
vi /etc/inetd.conf
Comment the line starts with Telnet or
FTP. Save the file and exit.
Stop and start the inetd daemon now by
following commands:
/etc/rc.d/init.d/inet stop
/etc/rc.d/init.d/inet start
(Your flavor may be /etc/init.d)
Now on nobody can telnet or FTP to your
server from outside network.
