General (Secure Shell Settings)

The options are:

Port number Specifies the port to connect to on the server. The default is 22, which is the standard port for Secure Shell connections.
Enable server Keep Alive When Enable server Keep Alive is selected, the client sends NOOP messages to the server through the secure tunnel at the specified interval. Use this setting to maintain the connection to the server. Use Interval to specify how frequently server alive messages are sent. If this is setting is not enabled, the Secure Shell connection will not terminate if the server dies or the network connection is lost. This setting can also be used to keep connections that only forward TCP sessions from being timed out by the server, as the server may timeout these connections because it detects no SSH traffic.

The Secure Shell Enable server Keep Alive setting is not related to the TCP keep alive setting that can be set in the Windows registry to keep all TCP/IP connections from being timed out by a firewall. To change the TCP/IP keep alive behavior, you need to edit the Windows registry.
Enable compression When Enable compression is selected, the client requests compression of all data. Compression is desirable on modem lines and other slow connections, but will only slow down response rate on fast networks.
Reuse existing connection if available By default, multiple sessions to the same host reuse the original Secure Shell connection, and therefore don't require re-authentication. If you clear Reuse existing connection if available, the client establishes a new connection for each session, which means that each new connection repeats the authentication process.
Logging Level Determines how much information is written to the Secure Shell log file.


  • The settings you configure in this dialog box are saved to the Secure Shell configuration file. You can also configure Secure Shell settings by editing this file manually in any text editor.
  • Within the configuration file, these settings are saved for the currently specified SSH configuration scheme.
