3 Authentication and Data Transmission
After the identification is verified and data encryption activated, a secure tunnel is established
between the client and the server. The client then sends its authentication information (user name
and password) to the server to log in to the server.
46.8.2 SSH Implementation on the UAG
Your UAG supports SSH versions 1 and 2 using RSA authentication and four encryption methods
(AES, 3DES, Archfour, and Blowfish). The SSH server is implemented on the UAG for management
using port 22 (by default).
46.8.3 Requirements for Using SSH
You must install an SSH client program on a client computer (Windows or Linux operating system)
that is used to connect to the UAG over SSH.
46.8.4 Configuring SSH
Click Configuration > System > SSH to change your UAG’s Secure Shell settings. Use this screen
to specify from which zones SSH can be used to manage the UAG. You can also specify from which
IP addresses the access can come.
