Fail to open a shell about ssh2-python HOT 3 CLOSED

Hi there,

Thanks for the interest and report.

Yes, this is an issue with the process_startup function. For shell requests, no message should be sent but the function does not allow that. An empty string as the message (as opposed to no message), is not accepted by the server which terminates the connection.

The next version will have a channel.shell() function which was missing - the libssh2 macro for shell process startup - as well as a revised process_startup which allows for no message.

From next version onwards:

channel = session.open_session()
channel.shell()
channel.write('my command\n')
size, data = channel.read()
<..>

Note that a pty is not explicitly required for interactive shells though it may be used.

Yes indeed, the macro in libssh2 uses a null pointer as message. My knowledge of Cython is limited, but I'll try to submit a pull request if I find the time. Thanks a lot!

That was fast, it's small fix but still. Thanks a lot, though I will open a new ticket. I would like to test your branch and the only way to find how to build it was to look at Travis. Keep up the good work!
