I tried a number of approaches to implementing ssh:. I finally settled on the following:
(1) Run the "ssh" command using system() to get a shell on the remote system. (2) Send an "echo" command and get the reply. Hopefully this will move past the welcome banner. (3) Run "fossil http" on the remote side. (4) Start sending HTTP requests from the local side to the remote, and accepting replies back. (5) After the last reply is received, shut down the SSH pipe. All of the above is pretty fragile based on what flavor of SSH you are running locally and on the remote, what kind of banner messages are issued by the remote, how the various SSH implementations handle password management and authentication, quirks and idiosyncrasies of both systems and their SSH implementation, etc. It works in many instances, but it is brittle and there are still issues. If you have a non-working scenario and can suggest changes to make the system more robust, then please contribute. -- D. Richard Hipp d...@sqlite.org
