http to socks5 proxy ansible role for homebase

[willk]

Privproxy is one way to do this, but newer versions of tinyproxy also can do this. In PP01, we have used privproxy as documented below.

privproxy allows us to have a socks5 upstream to an http proxy, which is convenient for tools that do not work will with proxychains or have built in support for socks proxies.

Privroxy is packaged, however, it installs as a broken package. It is broken because the daemon is started in the configuration stage of packaging, where it tries to listen on ::1 in addition to localhost. Fixing this in the configuration file allows it to start and an "apt-get -f install" will restore the packaging system to working.

By putting a line like below at the end of the config file, we have an http proxy going to a socks upstream.
