I'm not familiar with libssh and the remote shell... Just some idea:
Your pass_instruction function only checks if the write to the server
was successfull, but not the result of the remote command. Can it be
that remote side waits for a read before it passes the next line to the
shell?

The example at http://api.libssh.org/stable/libssh_tutor_shell.html uses
some read/write loop, like

  while (ssh_channel_is_open(channel) &&
         !ssh_channel_is_eof(channel))
  {
          read(...);
          ....
          write(...);
  }
