CentOS Linux Distribution Enable Telnet
From Free Knowledge Base- The DUCK Project: information for everyone
Want to install telnet?
telnet server is not recommended for security reasons, plain text over tcp/ip
# yum install telnet telnet-server -y
How about telnet client? It is not installed by default.
#yum intall telnet -y
The package is Package telnet.i686
Enable TELNET as ROOT on GUEST CentOS system
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. note: Just one is probably fine
