tinyproxy
For when squid would be overkill
Setup debian/ubuntu apt to use proxy
- e.g. tinyproxy running on 2nd machine, default port 8888 and example IP 10.13.55.13.
edit $ sudo vim /etc/apt/apt.conf.d/proxy.conf
Acquire::http::Proxy "http://10.13.55.13:8888"; Acquire::https::Proxy "http://10.13.55.13:8888";
