  Installing     : telnet                                                                                                                                                                                                   1/1
Installed:
  telnet.i386 1:0.17-39.el5
Complete!

After telnet installation, we go to just telnet configuration file through this commands

[root@localhost ~]# vim /etc/xinetd.d/telnet

[root@localhost ~]# vim /etc/xinetd.d/telnet
service telnet
{
        flags           = REUSE
        socket_type     = stream
        wait            = no
        user            = root
        server          = /usr/sbin/in.telnetd
        log_on_failure  += USERID
        disable         = no
}
~
~
~
~
:wq

Then we start telnet service [root@localhost ~]# service xineted restart

[root@localhost ~]# service xineted restart
[root@localhost ~]# chkconfig xinetd on

then we need any user account for telnet access so here we make the new user.

[root@localhost ~]# useradd vishnu1
[root@localhost ~]# passwd vishnu1
Changing password for user vishnu1.
New UNIX password:******
BAD PASSWORD: it is too short
Retype new UNIX password:******
passwd: all authentication tokens updated successfully.

then we  off our firewall

[root@localhost ~]# iptables -F
[root@localhost ~]# setenforce 0
setenforce: SELinux is disabled

now your telnet is ready we can access any remotely
