Paramiko SSH Tunnel Shutdown Issue

Question

I\'m working on a python script to query a few remote databases over an established ssh tunnel every so often. I\'m fairly familiar with the paramiko library, so that was my cho

You may want to add some synchronization between the spawned thread and the caller so that you don't try to use the tunnel before it is ready. Something like:

    from threading import Event   
    def startTunnel(self):
        class SubHandler(Handler):
            chain_host = '127.0.0.1'
            chain_port = 5432
            ssh_transport = self.c.get_transport()
        mysignal = Event()
        mysignal.clear()
        def ThreadTunnel():
            global t
            t = ForwardServer(('', 3333), SubHandler)
            mysignal.set() 
            t.serve_forever()
        Thread(target=ThreadTunnel).start()
        mysignal.wait()
