Troubleshooting a connectivity issue and reached for the good old telnet command, only to be greeted with a frustrating "telnet: command not found" error?
By default, Telnet isn't installed on many modern Linux distributions. Fortunately, installing it only takes a few seconds.
Run the following command:
sudo apt-get install telnet
Once installed, you'll be able to use telnet to test connectivity to remote hosts and ports.
