[Twisted-Python] How to write a simpletelnet client?

>>I didn't expect that one must handle control codes (your function reponseFunct), I expected the protocol to handle that for me, but anyway, that was no problem (i.e. you solved it before). And with your code I could even switch off the echo (your next thread).

>You don't actually have to do this.  You can implement iac_DO, iac_DONT, iac_WILL, and iac_WONT to handle feature negotiation.

>You can also use twisted.conch.telnet, which presents a slightly more complete API for feature negotiation.

Thank you, I'll look into it. It's better to use ssh anyway.

Thank you.

I don't understand how connectionMade would help me here - I use it to switch off ECHO, but everything else is in dataReceived to react on prompts. And I've telnet_Command to issue a command (i.e. I queue it while there's no connection), but if I use the Protocol in a Factory, I can't get my hands on it. Perhaps I simply shouldn't use a Factory.

I guess the UDP code you're discussing with Drake Smith will help me further, his task seems similar to mine.
