The Telnet protocol is one of TCP/IP protocols and the standard protocol for Internet remote
login. You can transfer the PC used by the local user to a terminal in remote host system
through the Telnet protocol. Using the Telnet program on the terminal user's PC, you can log
in to and manage the Gazelle S1512i-PWR.
SSH management
Secure Shell (SSH) is a protocol for secure remote login and other secure network services
over an insecure network. When users undergo remote logins, SSH will automatically encrypt
the data before transmission and decrypt them when the data arrive at the destination. By this
way, SSH protects network devices from various attacks, such as plaintext password
interception.
Moreover, SSH can replace Telnet to manage the remote device or provide a secure channel
for FTP, and so on.
