Click on the SSH/TELNET menu item and the following dialog window appears:
SSH
Server
Enable SSH Server:
Select YES to enable the SSH server.
Note:
Enabling the SSH Server does not, by
default, allow SSH data through the firewall. If you have connection problems, please check your firewall
settings.
Configure Advanced Parameters:
Select YES to configure advanced options for the SSH Server (Optional).
The recommended setting for this field is NO.
Listening IP Address:
Specifies the local IP Address on which the SSH server will accept connections.
Note:
Specifying a value of 0.0.0.0 allows the SSH server to accept connections on any interface. Firewall rules must
be present to allow SSH connection on untrusted interfaces. The recommended setting for this field is 0.0.0.0.
Listening IP Port:
Specifies the local IP port on which the SSH server will accept connections.
Note:
Specifying a value other than 22 will require proper firewall rules in order to allow connections to the given port.
The recommended setting for this field is 22.
Login Grace Time (seconds):
Specifies the amount of time, in seconds, after which the SSH server will
disconnect, if the user has not successfully logged in. The recommended setting for this field is 30.
