How to connect on remote computer

SSH(Secure Shell) and TELNET are the most commonly used tools in remote connection. The only difference between them is the security they possessed. SSH uses encryption in order to avoid eavesdropping, connection hijacking, and other attacks doing by hackers. Other tools are RLOGIN, VNC, and FTP.

Users of TELNET, RLOGIN, VNC, and FTP should not rely on these tools because during connection their password is transmitted across the Internet unencrypted. Through the use of sniffing tools, hackers could easily sniff you.
