Not Able to run telnet service on CentOS machine

Question

When I try to run the telnet service on CentOS Linux release 7.2.1511 it throws the following error:

service telnet restart 
Redirecting to /bin/systemctl restart 
telnet.service Failed to restart telnet.service: Unit telnet.service failed to load: No such file or directory.

The telnet server version running on my machine:

rpm -qa | grep telnet 
telnet-0.17-59.el7.x86_64 
telnet-server-0.17-59.el7.x86_64

How can I successfully start the telnet service on my machine?

Solution 1

You don't seem to have telnet installed. You can install it with:

sudo yum install -y telnet

Solution 2

On CentOS 6:

service xinetd start
chkconfig telnet on
chkconfig xinetd on

On CentOS 7:

systemctl start telnet.socket
systemctl enable telnet.socket

What's the command you used? Did you used root account?

Why do you start the telnet.socket? You have to start the telnet.service. And please, please don't paste multiline output in a comment (and if you put it in your post, be so kind as to format things correctly).

i have already run the command you gave and it shows "Package 1:telnet-0.17-59.el7.x86_64 already installed and latest version"

[Anthon]

Try to run yum reinstall telnet and if that doesn't help yum remove telnet followed by yum install telnet (all with sudo if appropriate)

Their rpm output shows that package is already installed. You enable the socket activation because that replaces the xinetd functionality. Example.
