Block Telnet 4 Users
« on: August 04, 2004, 07:53:57 AM »
Dear Users,

I am using RedHat Linux 8.0.
I dont want my users access SERVER though telnet from other machines
(like telnet 192.168.0.1) only root can access SERVER from others machines.

simply i want telnet block for users, only open on root

You can disable telent server service using xinetd

open /etc/xinetd.d/telnet and change disable to yes.

Basically uninstall telnet if you don't want it to be used on a server. :)

Yeah ,I agree with dragoncity.

telnet should not be installed on any of the linux box. This is good practice in most of the big companies.

You can use netcat aka "nc" instead.

If you wana block telnet ( for client PC)  then disable it on boot time.
