SSH Is the Secure Alternative to Telnet

by

Telnet sends traffic without encryption and should not be used for remote administration on modern systems. SSH is the standard secure alternative for remote shell access.

Connect with SSH

ssh user@server

Use the username and hostname or IP address of the remote server.

Use a different port

ssh -p 2222 user@server

Only use a custom port if the remote SSH service is configured to listen on that port.

Basic safety notes

  • Prefer SSH keys for regular access.
  • Disable unused remote-access services.
  • Do not expose administrative access unnecessarily.
