Add the wildcard INADDR_ANY [0.0.0.0]

Let the function find a listen port when we have applications listening on INADDR_ANY [wildcard - 0.0.0.0]. This means that the application will be heard on all local interfaces and can connect to the port on any of them.

Don't request a PTY if we don't have a password for sudo

When requesting a PTY, stdout and stderr are mixed in a single flow. The
PTY is useless if we don't have a password to provide to
sudo. Therefore, just don't request one without a password. Also, catch
the error sudo emits when it complains it needs a password but doesn't
have a terminal for it. This error is emitted on stderr when we don't
have a PTY.
