hello guys today we will discuss about secure telnet Server. basically secure telnet is a custom telnet its same copy of telnet server but here we will configure with our customize port.If you  want to know how to configure simple telnet server so click on link. before we telnet package in our linux machine. if we want we can install every type package easily  so  we need  to Yum server configuration you just click on link and look how to configure yum. Stelnet Server

Here I agree that you have configured YUM server in your machine

For any Tutorial visit linuxtiwary.com

then let we start

Step1 we will install telnet package below commands 

[root@localhost ~]# yum install telnet*

Step2 then we will go Xinetd configuration file and look if we found disable is =no so we will do yes . we will open Xinetd file below commands 

[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         = yes
}
~
~
~
~
:wq

Step3 After configuration we are doing copy telnet file 

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

Strp4  now we are going to /etc/services file and create customize port                    stelnet         8888/tcp                        #secure telnet  

[root@localhost ~]# vim /etc/services
  20 # service-name  port/protocol  [aliases ...]   [# comment]
  21 stelnet         8888/tcp                        #secure telnet
  22 tcpmux          1/tcp                           # TCP port service multiplexer
  23 tcpmux          1/udp                           # TCP port service multiplexer
  24 rje             5/tcp                           # Remote Job Entry
  25 rje             5/udp                           # Remote Job Entry
  26 echo            7/tcp
  27 echo            7/udp
  28 discard         9/tcp           sink null
  29 discard         9/udp           sink null
  30 systat          11/tcp          users
  31 systat          11/udp          users
~
~
~
:wq

Strp4  now we are going to stelnet  configuration file. then we will   write customize port 8888  and disable=no 

[root@localhost ~]# vim /etc/xinetd.d/stelnet
service stelnet
{
        flags           = REUSE
        socket_type     = stream
        wait            = no
        user            = root
        server          = /usr/sbin/in.telnetd
        log_on_failure  += USERID
        disable         = no
        port            =8888
}
~
~
:wq

Step6 after configuration we will restart telnet service and off  firewall ,selinux service  below commands

[root@localhost ~]# iptables -F
[root@localhost ~]# setenforce 0

Step7 now go to client side and put command prompt in below commands 

telnet 192.168.56.1 8888           (note-put your server machine ip address with customize port) 

then put your username and password and login through telnet. if you have any problems in this processso comment here i will solve your problems
