SSH
Developed by SSH Communications Security Ltd., Secure Shell is a program to log
into another computer over a network, to execute commands in a remote machine,
and to move files from one machine to another. It provides strong authentication and
secure communications over insecure channels. It is a replacement for rlogin, rsh,
rcp, and rdist.
SSL
Secure Sockets Layer. It is a popular encryption scheme used by many online retail
and banking sites to protect the financial integrity of transactions. When an SSL
session begins, the server sends its public key to the browser. The browser then
sends a randomly generated secret key back to the server in order to have a secret
key exchange for that session. SSL VPN is also known as Web VPN. The HTTPS
and SSH management interface use SSL for data encryption.

subnet for all the local computers it talks to.
