Linux is configured to run the Telnet , but by default, these services are not 
enabled. To enable the telnet these service, login to the server as the root 
userid and edit the files:

 /etc/xinetd.d/telnet 

In this file, find the line for disable and change it from the value "yes" to 
"no".

After changing the above value(s), you will need to restart the xinetd deamon. 
As the root userid, type the following command:

/etc/init.d/xinetd reload

Now before getting into the details of how to configure Red Hat Linux for root 
logins, keep in mind that this is VERY BAD security. Make sure that you NEVER 
configure your production servers for this type of login.

 Simply edit the file /etc/securetty and add the following to the end of the 
file:

pts/0
pts/1
pts/2
pts/3
pts/4
pts/5
pts/6
pts/7
pts/8
pts/9

This will allow up to 10 telnet sessions to the server as root.

Cheers.

Manuel.
