It is normal that the session gets closed after an exec request (see the RFC). 
If you don't want that use a non-interactive shell ...

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

There is no example, but you could improve the docs once you get it working!

You need to use ssh_channel_request_shell() and you need some protocol to find 
out if your command was successful or not like:

./mytool && echo SSH_OK || echo SSH_KO


I hope this helps :-)
