If you open shell already, request_exec is no longer possible in that particular channel. At that point, the shell is already running in the server and you can run commands there by sending data to it and reading data as described in tutorial: https://api.libssh.org/stable/libssh_tutor_shell.html If I read the logs right, device does not allow you to exec command directly, but allows only shell access.
