# NNTPChan #
![le ebin logo](nntpchan.png "ebin logo")
NNTPChan (previously known as overchan) is a decentralized imageboard that uses nntp to synchronize content between many different servers. It utilizes cryptographically signed posts to perform optional/opt-in decentralized moderation.
![MIT License](https://img.shields.io/github/license/majestrate/nntpchan.svg)
![Logo is ebin](https://img.shields.io/badge/logo-ebin-brightgreen.svg)
This repository contains resources used by the core daemon which is located [here](https://github.com/majestrate/srndv2) along with general documentation, [here](doc/)
## getting started ##
After you [built and installed the daemon](doc/build.md) and [set up your database](doc/database.md), clone this repository and start up the daemon
# clone it
git clone https://github.com/majestrate/nntpchan ~/nntpchan
# get the latest stable release
cd ~/nntpchan/
git checkout tags/0.2.1
# set up the workspace
srndv2 setup
# run the daemon
srndv2 run
**NNTPChan** (previously known as overchan) is a decentralized imageboard that uses the [NNTP protocol](https://en.wikipedia.org/wiki/Network_News_Transfer_Protocol) (network-news transfer protocol) to synchronize content between many different servers. It utilizes cryptographically signed posts to perform optional/opt-in decentralized moderation.
Then open http://127.0.0.1:18000/ukko.html in your browser.
## Getting started
*PLEASE* report any bugs you find while setting up or building [(here)](https://github.com/majestrate/nntpchan/issues) so that the problems get fixed (^:
[This](doc) is a step-by-step guide for getting up-and-running with NNTPChan as well as documentation for developers who want to either work on NNTPChan directly or use NNTPChan in their aplications with the API.
TL;DR edition:
For peering requests, questions or support find me on [rizon](https://qchat.rizon.net/?channels=#nntpchan) as \__uguu\__
$ sudo apt update
$ sudo apt install --no-install-recommends install imagemagick ffmpeg sox build-essential git ca-certificates postgresql postgresql-client
$ git clone https://github.com/majestrate/nntpchan
$ cd nntpchan
$ make
$ SRND_INSTALLER=0 ./srndv2 setup

## Bugs and issues
bitcoin: 15yuMzuueV8y5vPQQ39ZqQVz5Ey98DNrjE
*PLEASE* report any bugs you find while building, setting-up or using NNTPChan on the [GitHub issue tracker](https://github.com/majestrate/nntpchan/issues), the [issue tracker on tor](http://git.psii2pdloxelodts.onion/psi/nntpchan/), the [issue tracker on i2p](http://git.psi.i2p/psi/nntpchan/) or on the [GitGud issue tracker](https://gitgud.io/jeff/nntpchan/issues) so that the probelms can be resolved or discussed.
## Clients
NNTP (confirmed working):
* Thunderbird
Web:
* [Yukko](https://github.com/faissaloo/Yukko): ncurses based nntpchan web ui reader
## Support

## History
* started in mid 2013 on anonet
This is a graph of the post flow of the `overchan.test` newsgroup over 4 years, quite a big network.
