I'm trying to use the Dropbear SSH and in the previous version of SSH I used, you could add the argument -o ConnectTimeout=10 to cause an attempted connection to timeout if unsuccessful after ten seconds.

Is there a way to programmatically specify a connection timeout when using Dropbear SSH?

Looking through the code, it appears that the only timeout you can configure on the client side is the idle timeout, which you can configure with the -I option followed by the idle timeout in seconds.

On the server side there's a timeout which kills incoming connections if the client doesn't authenticate within five minutes, but it's not configurable at runtime; you'd need to edit sysoptions.h and rebuild. The only command-line configurable timeout on the server side is the idle timeout, in the same way as on the client.
