SSH - Secure Shell
SSH
The secure shell (SSH) is now the de facto standard for remots logins to other machines.
It has replaced old, insecure programs such as
telnet
and
rlogin
.
SSH offers the following:
All data is encrypted, including the password.
You can tunnel other network connections.
Tunnelling is the process of packaging and transporting a network connection using another network connection.
I.e., we can tunnel X Window System connections and the data will be encrypted.
SSH has clients for almost every operating system.
SSH uses keys for host authentication.
