How to disable Telnet & Other Unused Services

Disable Telnet & Other Unused Services


Telnet is an unsecured network protocol that facilitates remote login to a server via network connection. The protocol allows server to be located thousands of miles away from the administrator yet still can be managed even without physical console access. However, Telnet has slowly replaced with SSH (Secure Shell)
You may want to disable services like telnet and other unwanted services running on your server with xinet.

1. Login to server as root
2. vi /etc/xinetd.d/telnet
// OR
3. vi /etc/xinetd.d/krb5-telnet
look for lines disable=no and change to disable=yes
4. chkconfig telnet off
