Hello!

I am trying to set up stunnel from a windows box to a VPS.
I have working tunnels from a FreeBSD box to the VPS.

On the VPS, the config looks like:

[socks_server]
protocol = socks
PSKsecrets = /my/secret/location/secrets.txt
accept = xxx.xxx.xxx.xxx:xxxx

[ssh]
PSKsecrets = /my/secret/location/hecrets.txt
accept = xxx.xxx.xxx.xxx:xxxx
connect = 127.0.0.1:22

On the windows box, the config looks like this:

[socks_client2]
debug = 7
client = yes
PSKsecrets = c:\my\secret\location\secrets.txt
accept = 127.0.0.1:1080
connect = xxx.xxx.xxx.xxx:xxxx

The log on Windows looks like this:
