I just wondered what's the best way to socksify an application, e.g. to tell it to use a SOCKS5 proxy. I see redsocks is available in OpenWrt but that's a bit heavyweight as I only need a single application to be redirected, and I couldn't get it working anyway. Then I tried socksify and that didn't work either, that problem seems to be described here.
Any ideas?
is it an application running on the router ?
Yes, ssh in fact.
There used to be apps for it, like httptunnel, there's sshtunnel now, but i don't know if it does what you'd like it to do.
After banging my head against it for long enough I made redsocks work in the end.
How you do that?
The most useful resource is Alexander Molochko:
However since I am only hooking ssh, and only for one specific destination, my setup is much, much simpler, so I just need three rules:
iptables -t nat -N REDSOCKS
iptables -t nat -A REDSOCKS -p tcp -d <my destination ip> -j REDIRECT --to-ports <redsocks port>
iptables -t nat -A OUTPUT -p tcp --dport 22 -j REDSOCKS
Then of course, you setup redsocks config to point to your proxy, and accept connection on the <redsocks port>
I am using Dante proxy (running external to OpenWrt).
I would have preferred to get intercept for just the ssh application. I'm not sure whether the problem with socksify + ssh is about the libc used by ssh or the problem is with socksify, but this is working for now, so...
Hope this helps.

This website is so slick it's surprising there isn't a button to do that, but it's done.
I went to check older posts and mark solved, but unfortunately it only allows editing back so far. I guess that makes sense.
