Configuring Secure Shell (SSH) server and client
Use TCP port p
The TCP port number (default 22) that the SSH server will use to listen for incoming
connections. (Port 22 is the standard SSH port).
Allow up to n connections
The number of sockets listening for new SSH connections (default 1).
Host Key 1 Filename
The filename of either an SSH V1 or V2 host key. It is highly recommended that the filename be
prefixed with priv to ensure that the key cannot be easily accessed and compromised. This key
may be generated using the facilities described in the Certificates section of this manual.
Host Key 2 Filename
The filename of either an SSH V1 or V2 key as above.
Note The maximum length for these filenames is 12characters and they must use the DOS 8.3
file naming convention.
Maximum login time s seconds
The maximum length of time, in seconds, a user can successfully complete the login procedure
once the SSH socket has been opened. The socket is closed if the user has not completed a
successful login within this period.
Maximum login attempts n
The maximum number of login attempts allowed in any one session before the SSH socket will
be closed.
Use Deflate compression No/Yes, level n
Sets use of DEFLATE compression. If compression is selected, the compression level is chosen
from the drop-down list.
Enable Port Forwarding
When enabled, the router accepts traffic on ports other than 23. This functionality is for use
with SSH client applications, such as PuTTY, that have port forwarding capability. For example,
one the SSH connection is active, traffic for the HTTP port 80 can be sent to the router
securely.
Command Session IP Address a.b.c.d Port p
The values in these two text boxes specify the host IP address and port number that the router
uses to handle incoming requests for a command session from SSH clients. This is instead of
the router's normal command interpreter. For example, if the values are IP address 127.0.0.1,
port 4000, the SSH client will make a direct connection to ASY 0 and the device attached to
ASY 0 will receive and process the commands from the SSH client.
