wslbridge is a Cygwin program that allows connecting to the WSL command-line environment over TCP sockets, as with ssh, but without the overhead of configuring an SSH server.
You'll need a Cygwin (32 or 64 bit) environment, as well as a WSL environment (or any other Linux environment). Make sure you have the g++ and make packages installed.
In Cygwin:
$ cd frontend
make
In WSL/Linux:
$ cd backend
make
The Cygwin frontend program is written to out/wslbridge.exe. The ELF64
backend program is written to out/wslbridge-backend. The files can be copied
somewhere more convenient, but they need to be on a letter drive (e.g. not a
\\server\share\... UNC path). They also need to be on an NTFS volume. The
frontend looks for the backend in its own directory.
Usage is similar to that of ssh. Run wslbridge with no arguments to start
a bash session in a WSL pty. Append a command-line to run that command in WSL
without a pty (i.e. using 3 pipes for stdio).
wslbridge runs its WSL command with either a pty or using pipes. Pass -t
to enable pty mode or -T to enable pipe mode. Pass -t -t to force pty mode
even if stdin is not a terminal.
Pass -eVAR=VAL to set an environment variable within WSL. Pass just -eVAR
to copy the value from the Cygwin environment.
The mintty project provides wsltty, a standalone WSL terminal package containing mintty, wslbridge, and part of Cygwin (e.g. the runtime library).
