I’m always getting twisted.internet.error.ReactorNotRestartable after trying it while reactor.running is False.

If you put a reactor.stop() at the end of ssh._ebExit, test.py should run to completion after doing the remote file operations and executing the remote commands. > > Is that the desired behavior? No. I need a solution where the call to executeRemoteCommands() is delayed until all remote file operations are complete. Similar the next call to distributeFiles (with a different host) must wait until the previous call to executeRemoteCommands has no outstanding operations. > > If there is a second case, what one edit can I make to observe that behavior? No. > How does the behavior differ from what you’re trying to achieve? See above. I must synchronize operations at 2 points in a loop. I tried to do this with callbacks, called at connection shutdown.

I looked at endpoints before, but failed to implement public key authentication and a callback when complete.
