Use: $ git clone --recursive --depth=1 https://github.com/Anoncheg1/diboard.git

diboard v1.0.8 Decentralized ImageBoard just like nntpchan with following differences:

• scientific research on this topic
• main goal of project is a quality of code
• the least possible amount of third-party libraries
• more accurate with rfc
• philosophy: closed groups of trusted servers to protect against flood and user fingerprint leaks.

Structure:

1. Import Existing Maven project diboard
2. Import Existing Maven project dibd - Main core NNTP module that can work independently.
3. Import Existing Maven project webspringboot - Web-frontend. Spring boot with embedded Tomcat.

System Requirements

• Min RAM for everything 600MB free.
• Java 8 JDK.
• ImageMagic. (used for thumbnails)
• PostgreSQL or MySQL.

Installation

1. Install RDBMS: postgresql (or mysql)
2. Create database

$ su
# su postgres
$ psql
postgres=# CREATE ROLE dibd WITH LOGIN PASSWORD 'mysecret';
postgres=# CREATE DATABASE dibd WITH OWNER dibd ENCODING 'UTF8';
postgres=# \q
$ psql dibd
dibd=# \i /home/user/diboard/dibd.SQL

3. configure webspringboot/dibd.conf
4. install ImageMagic (read https://www.imagemagick.org/script/security-policy.php)
5. Compile

$ cd diboard
$ mvn clean compile package

6. Run

$ cd webspringboot
$ java -jar target/diboard.jar -p 9119

To run as a daemon on port 119 see dibd/util

Port 119 may be accessed local for debug:

iptables -t nat -I OUTPUT -p tcp -d 127.0.0.1 --dport 119 -j REDIRECT --to-port 9119

Features:

• No JavaScript.
• Short links works globally
• No message loss even with too large attachment.
• Fully compatible with nntpchan network (except tripcodes, AUTH command, decentralized moderation, DKIM).
• Only images supported for now. One attachment per post.
• SOCKS proxy connection for Tor OR i2p working.
• Flexible control of used disk space and used resources.
• Abstract API for implementing any JVM supported web-frontend (with thread pool or with dynamically spawn threads).

Knews issues:

• Impossible to chage HTML templates without recompilation.
• HTTP proxy not supported.

TODO:

1. create another web-frontend with external templates and more minimalistic.
2. replace XOVER with new commands.

For nntpchan:

• Fix XOVER and block empty articles.

jar verification:

$ gpg2 --import pubkey.asc
$ cd webspringboot/target/
$ gpg --verify diboard.jar.sig diboard.jar
