How to stop socat from quitting?

Question

I am using socat for windows as a client to tunnel DNS over SSH, it works perfectly until the ssh connection dies or becomes temporarily unavailable - when this happens the socat windows client terminates and requires restarting.

I am using the following command on windows client:

socat -s udp-recvfrom:53,reuseaddr,bind=127.0.0.1,fork tcp:127.0.0.1:5377

Does anyone know a way to prevent the socat client from quitting when the ssh connection becomes unavailable? The help file suggests the -s switch solves this but it doesn't.

You could wrap the command with an [infinite loop](http://stackoverflow.com/questions/5487473/how-to-create-an-infinite-loop-in-windows-batch-file). — C2H5OH, Apr 02 '12 at 18:56
Not sure how to create an infinite loop - I'm running the command from a compiled vbscript with WshShell.Run "socat.exe -s udp-recvfrom:53,reuseaddr,bind=127.0.0.1,fork tcp:127.0.0.1:5377",0,false — Kyoku, Apr 02 '12 at 19:26

Following your comment, a loop in VBScript (what Windows Scripting Host uses) is easier:

Do
    WshShell.Run "socat.exe -s udp-recvfrom:53,reuseaddr,bind=127.0.0.1,fork tcp:127.0.0.1:5377",0,True
Loop While True

this doesn't work, it just launches thousands of socat.exe processes – Kyoku Apr 02 '12 at 20:48
@Kyoku: Sorry, my bad. Change the last `false` with `true` in the line you launch `socat` – C2H5OH Apr 02 '12 at 20:55
