You seem to be confusing the purpose of these function calls.

libssh2_channel_exec() can only be used with a channel that was
created by libssh2_channel_open_session().

libssh2_channel_direct_tcpip_ex() creates a different type of
channel. Please read RFC4254 to learn more about direct-tcpip
channels.
