# Opens a port of this machine to the outside through a tunnel.

# The tunnel runs here, the far side gets a port it can connect to, and the
|
|
# address to enter on the other machine is printed at the end.
|
|
#
|
|
# The usual use is the remote desktop: the port 3389 is forwarded and the
|
|
# remote desktop client connects to the address of the tunnel. The connection
|
|
# comes from the loopback, so the port of the remote desktop service does not
|
|
# have to be open on the local network.
|
|
#
|
|
# The bore server that serves ru.zern.cc listens on 7835 and holds the secret
|
|
# that the client and the server share. The old bat file on the desktop points
|
|
# at zernmc.ru, which is no longer reachable; ru.zern.cc is the one that works.

# ASCII only: PowerShell 5.1 reads a .ps1 without a byte order mark using the
|
|
# system ANSI code page.
