Dial-up was the main way to connect to the Internet back in the 90s. Unfortunately, within the time almost all of the dial-up service providers are shut down, because of obvious reasons. It used to connect our living room to the world via 56 kbps (or less) bandwidth rate, in comparison, modern broadband global mean is two thousand times faster. But sometimes we still need it to connect our legacy hardware to the world, retro (or lowres) computing purposes, sometimes even to circumvent censorship.

In this talk, after a brief on the dial-up connection and it's nature, notes and methods on running a personal dial-up ISP and connecting to it will be covered; starting from hardware requirements for both ISP and client side and the software stack for GNU/Linux operating system to run a dial-up system, using only free/libre software.
