File Tunnel

 

Tunnel TCP connections through a file.


Download

 

Portable executables for Windows and Linux can be found over in the
releases section.


Example 1 - Bypassing a firewall

 

ft_fw

You'd like to connect from Host A to Host B, but a firewall is in the
way. But both hosts have access to a shared folder.

Host A

 

ft.exe --tcp-listen 127.0.0.1:5000 --write "\\server\share\1.dat"
--read "\\server\share\2.dat"

Host B

 

ft.exe --read "\\server\share\1.dat" --tcp-connect 127.0.0.1:3389
--write "\\server\share\2.dat"

Now on Host A, configure the client to connect to: 127.0.0.1:5000




Example 2 - Tunnel TCP through RDP (similar to SSH tunnel)

 

You'd like to connect to a remote service (eg. 192.168.1.50:8888),
but only have access to Host B using RDP.

Host A

 

ft.exe --tcp-listen 127.0.0.1:5000 --write "C:\Temp\1.dat" --read "C:
\Temp\2.dat"

Run an RDP client and ensure local drives are shared as shown here.

Connect to Host B.

Host B

 

ft.exe --read "\\tsclient\c\Temp\1.dat" --tcp-connect
192.168.1.50:8888 --write "\\tsclient\c\Temp\2.dat"

Now on Host A, you can connect to 127.0.0.1:5000 and it will be
forwarded to 192.168.1.50:8888




How does it work?

 

The program starts a TCP listener, and when a connection is received
it writes the TCP data into a file. This same file is read by the
counterpart program, which establishes a TCP connection and
onforwards the TCP data. To avoid the shared file growing
indefinitely, it is purged whenever it gets larger than 10 MB.
