tuntun

README

Basic ssh tunnel minder that works as a Windows service and has no external
dependencies. It supports tunnels in both directions, password or key-file
authentication, SSH keepalives, and exponential backoff.

To install as a windows service, first move the EXE to a permanent location
(like in C:\Program Files\TunTun\) then run "tuntun.exe install"

It will look for a config file in C:\ProgramData\TunTun\config.json
Here is a sample config:
