Linux Telnet Configuration

What is Telnet ?

Telnet Server- Telnet Server is a Network Protocol used on the Internet or local area network to provide a bi-directional interactive communications facility.

Or,

Telnet is a user command and underlying TCP/IP Protocol for accessing Remote Computer.

Drawbacks:-

1. Telnet don’t give permission to log in root directly, we can log in to other user than we can switch root user.

2. Clean text communication, no encryption of data.

3. We can not transfer data over network through telnet.

4. Only for remote access the terminal emulation

Here is the simplest way to configure Telnet Server.

1. We need to check RPM package information of telnet first.

command to check RPM package-

[root@local..]# rpm -qa telnet*

or

[root@local..]# rpm -qa | grep telnet

2. If package not installed than we can install it through two way

a. insert RHEL cd and mount cd than search rpm packages than run command

[root@local..]#rpm -ivh telnet*

or,

b. We can install it through Internet using YUM command.

]# yum install telnet*

Through these commands we can install rpm of telnet.

3. Now we should start service with command

[root@local..]# service xinetd restart

Note- xinetd daemon is responsible for Telnet services.
You can start/stop/restart xinetd after booting by using the following commands:[root@local..]# service xinetd start

[root@local..]# service xinetd stop

[root@local..]# service xinetd restart

4. Than we should run command

[root@local..]# chkconfig telnet on     (this command used to permanent on the service telnet)

Now your Telnet server Installed and ready to use…;)
