Check Content

Verify that the telnet package is not installed on the Ubuntu operating system.

Check that the telnet daemon is not installed on the Ubuntu operating system by running the following command:

# dpkg -l | grep telnetd

Remove the telnet package from the Ubuntu operating system by running the following command:

# sudo apt-get remove telnetd
