Keep alive the session after remote execution of the commands

[Javad Rahimi <javad321javad@xxxxxxxxx>]

Hello,

We have developed a simple ssh client application based on this
<https://api.libssh.org/stable/libssh_tutor_command.html> example (libssh:
Chapter 4) to run a command remotely and return the results. However, the
ssh server disconnects the connection after executing the command and
returning the result.
However, it doesn't happen for all SSH servers.
Is there any way to force the ssh server to keep alive the session after
executing

Best Regards,
Javad
