The Timeout property specifies how many seconds must pass
without any activity between wodSSHTunnel and the SSH server
before wodSSHTunnel will disconnect from the server.
This provides a measure of protection against
'ghost' connections being made between the client and the
server. If you don't want auto-disconnection to occur,
set the Timeout property to 0.
Timeout can be changed during the lifetime of a
connection. You should not set it below 120 (2 minutes)
if you are on slow network connection.
To prevent unwanted timeouts from occurring (perhaps due to an intermediate
gateway killing your connection), wodSSHTunnel
will send an IGNORE packet after half of your timeout setting
has expired. If there is no reply, then the connection will timeout
after the predefined number of seconds.
