>>81I used to have a headless box running some linux distro - can't remember which exactly but it was probably Ubuntu back in the early days - and hellanzb. It's still around and some good guides on how to configure it still exist.
A quick Google search has led me to better options such as SABnzbd and NZBGet. Web interfaces and all, even the option to get par archives to repair missing pieces.
Definitely a requirement when downloading from Usenet as some pieces can get corrupted/dropped easily.
I did this back when ISPs still had Usenet servers as part of basic service - FWIW I probably should have used a service that allowed secure tunnelling of traffic. If you're looking around for one at the very least go for that. Don't worry about using a VPN so much as at least having your connection between you and the Usenet server obfuscated so your ISP can't sniff packets (like they do with p2p/torrent on the default port to catch noobs).
My setup was simple, check around for a .nzb file of something that interested me, download it and the send it via a web frontend to my server. It would parse the file, connect to the Usenet server and begin gathering the relevant pieces, put them together, repair the archives if necessary, and even extract it and remove the archives and other unnecessary bits.
The amount of data I started gathering was enormous and this was when 500GB hdds were just hitting the market, so of course I had to have a JBOD/RAID5 setup which the nzb server eventually turned into. IIRC, torrents were also becoming a 'thing' and looked like an interesting way to contribute back to the community. I found an invite-only place called ftwr.in (it's dead now) and proceeded to gather a large amount of followers as well as find new things to grab from others. The amount of CDs I had to purchase to off-load my data onto strains credulity and I still have boxes of CDs I haven't touched in years, full of things I'll never use.
The amount of sheer technical knowledge I gained from running/securing my own servers and becoming a figure that others had depended on for their data (I liked to grab zero-day stuff then) was very useful. Fast-forward to now and I'm writing this from my Funtoo laptop (Gentoo derivative) and have been giving serious thought to starting yet another linux distro of my own design. Currently I'm a freelance DBA/Admin and am very happy with what I do.
I do hope that your foray into using Usenet and nzb is as fruitful as mine was.
