Hello,
Hi Fabian,
I implemented a twisted ssh server using SSHFactory and successfully registered the sftp factory.
Great, you're pretty far along then :).
I now also wanted to add a simple telnet like protocol where I can send commands to the server and execute some actions based on that. For that I hooked the LineReceive to the openShell command. It works and I can ssh into the server, but I don't get the typed characters echoed back. This unfortunately makes it unusable.
What I could do is to implement a standard Protocol and send the received data back whenever I get a dataReceived call. And for a DEL character I would have to send a BCKSPC, BLANK, BACKSPC sequence and track the current line myself. This works but it sounds like too much to do!
Is there a better way for something like that?
Have you looked at HistoricRecvLine https://twistedmatrix.com/documents/current/api/twisted.conch.recvline.Histo...? It's not the easiest class to use, but it should do basically what you need, with various line-editing niceties. This is also an area that could really benefit from some more maintenance, both in the code and the documentation; writing a command-line interface to Twisted should be a lot easier and more obvious. So if you'd like to contribute to Twisted this is a good place to start :). -glyph
