If you are still using Telnet services for connecting your PC to your dedicated server then you should disable it as server security step. Usually all webhost don’t disable telnet services for your server. Telnet uses port 23 by default for operating this service. Its always recommended to use SSH rather then telnet if you want to connect to server. Its more secure then telnet and is widely used by all webmasters.
As Telnet sends all passwords and usernames in clear text format rather then in encrypted form hence its not secure to use this service as there are more chances for getting your dedicated server hacked which will create trouble for your server.
How to Disable Telnet service for your dedicated server.
1. Login to your server through SSH and su to root.
2. Type pico /etc/xinetd.d/telnet
3. Search line: disable = no in above file and replace No with yes ie disable = yes
4. Now restart the inetd service: /etc/rc.d/init.d/xinetd restart
5. Lastly you need to scan your server to ensure port 23 is closed.
nmap -sT -O localhost
Also run ps -aux | grep telnet and if you find anything other than “grep telnet” as result kill the process.
