SSH Server n

The router supports eight individual SSH servers that are configured independently using the
options described below.
Enable SSH Server
When checked, this checkbox enables the SSH server.
Use TCP port p
The value in this text box is 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 value in this text box specifies the number of sockets listening for new SSH connections
(default 1).
Host Key 1 Filename
The value in this text box is 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 value in this text box is the filename of either an SSH V1 or V2 key as above.
Note The maximum length for these filenames is 12 characters and they must use the DOS 8.3
file naming convention.
Maximum login time s seconds
The value in this text box specifies the maximum length of time (in seconds) that a user is
allowed to 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 value in this text box specifies 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
The radio buttons select whether or not DEFLATE compression will be used. If compression is
selected, the compression level is chosen from the drop-down list.
Enable Port Forwarding
When checked, this checkbox enables the router to accept traffic on ports other than 23. This
functionality is for use with SSH client applications (such as PuTTY) that has port forwarding
capability. For example, one the SSH connection is active, traffic for the HTTP port 80 can be
sent to the router securely.
