a) you need a non-interactive shell

http://api.libssh.org/stable/libssh_tutor_shell.html

b) you should to check if it succeeded or not

./mycommand && echo OK || echo KO

So after you sent it, read from the channel and create a command protocol.


Let me know if you get it working. It would be great to get

http://api.libssh.org/stable/libssh_tutor_shell.html

updated with an example for this.
