15.6 The SSH Screen
You can use SSH (Secure SHell) to securely access the LAN-Cell’s SMT or command line
interface. Specify which interfaces allow SSH access and from which IP address the access
can come.
Unlike Telnet or FTP, which transmit data in plaintext (clear or unencrypted text), SSH is a
secure communication protocol that combines authentication and data encryption to provide
secure encrypted communication between two hosts over an unsecured network. In the
following figure, computer A on the Internet uses SSH to securely connect to the WAN port of
the LAN-Cell for a management session.
Figure 203 SSH Communication Over the WAN Example
SSH Implementation on the LAN-Cell
Your LAN-Cell supports SSH version 1.5 using RSA authentication and three encryption
methods (DES, 3DES and Blowfish). The SSH server is implemented on the LAN-Cell for
remote SMT management and file transfer on port 22. Only one SSH connection is allowed at
a time.
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 LAN-Cell over SSH.
