Re: [tor-relays] many connections

Hi Richie

I was a bit lost myself having to deal with the scripts and additional packages to install. So I put something together for myself based on the same rules and added a few twists but in a simple text n00b proof format. It's as simple as copy and paste and because it's all in clear text, you can modify it without worrying about breaking any script. My rules are a tad more strict but you can modify them as you wish. But the concept is what @toralf has been implementing with a few twists for efficiency's sake.

You can find them here:
