As of 20250627, 3chen.org has become actually alive. I had in prior over the period of 20250427 -> 20250528 had an OpenBSD to learn about the operating systems and write some basic board software. I eventually decided to decommission that server and opt for premade Japanese Warez. Setting it up per the information provided was quick - and the nginx configuration:

server {
    server_name 3chen.org;
    ...
    root /var/www/3chen.org;

    # /index.html -> /
    rewrite ^/index.html$ / permanent;
    rewrite ^/$ /index.html last;

    # /kareha.pl/.../ -> /.../
    rewrite ^/kareha.pl/([0-9\#\/]+) /$1 redirect;
    rewrite ^/([0-9\#\/]+) /kareha.pl/$1 last;

    include .../3chen.org/bans;

    location ~ \.(css|js|png)$ {
        add_header Cache-Control "max-age=86400";
    }

    location ~ (captcha|admin|kareha)\.pl {
        add_header Cache-Control "max-age=0; must-revalidate; no-cache";
        include fastcgi_params;
        fastcgi_pass  unix:/run/fcgiwrap.socket;
    }

    location / {
        add_header Cache-Control "max-age=0; must-revalidate; no-cache";
        index kareha.pl;
    }

    location = /config.pl {
        deny all;
    }
}

Simple enough. Kareha is easy, databaseless, and old. It was developed over 2004~ -> 2009 as far as I can tell (Using 20 year old web software is generally frowned upon.) The configuration process was straight forward and I do not have any significant notes. I removed the "last 50/100" system in preference for just load everything.

Xolatile made the CSS for it.
