Session.Open() timeout variable

Is there a user configurable variable for the timeout of the Session.Open?
I've tried setting Session.Timeout to 1000 ms, but it seems to be taking ~22 seconds to time out on an unreachable host regardless.

Thanks

Use SessionOptions.Timeout:

Thanks. I tried this as well, using the SessionOptions.TimeoutInMilliseconds and SessionOptions.Timeout, but it's not having any effect on the open timeout.

What protocol? Can you post a log file?

I'm using the SCP protocol.

Log files attached. Timeout set to 2000 ms in this instance. Values less than 1 second show as 0 in the log.

OK, indeed, the timeout does not seem to work correctly. I'll look into it.

Thanks for looking into this Martin.
For a workaround I just attempt to open a connection to the host using a raw TCP connection and then just check for the SSH ID string within a certain time.
