How to Install Telnet Client on CentOS 6.3 by ehowstuff on September 9, 2012

Telnet is most likely to be used by system administrators, program developers and anyone who has a need to use specific applications or data located at a particular host computer. It’s a network protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. Telnet does not installed automatically on CentOS 6.3. You can issue the following command to confirm that telnet is working :

telnet localhost 80

If telnet client does not installed, it should return something like :

[root@centos63 ~]# telnet localhost 80
-bash: telnet: command not found

Issue the following command to install telnet client :

[root@centos63 ~]# yum install telnet -y
