    @Panda said in Cloudflare bot fight mode and Google search:

    Basic question again, is nginx necessary to use?

    No, but you’d need something at least to handle the inbound requests, so you could use Apache, NGINX, Caddy… (there are plenty of them, but I tend to prefer NGINX)

    @Panda said in Cloudflare bot fight mode and Google search:

    Do these two sites need to be attached to different ports, and the ports put in the DNS record?

    No. They will both use ports 80 (HTTP) and 443 (HTTPS) by default.

    @Panda said in Cloudflare bot fight mode and Google search:

    Its not currently working, but how would the domain name know which of the two sites to resolve to without more info?
    Currently it only says the IP of the whole server.

    Yes, that’s correct. Domain routing is handled (for example) at the NGINX level, so whatever you have in DNS will be presented as the hostname, and NGINX will expect a match which once received, will then be forwarded onto the relevant destination.

    As an example, in your NGINX config, you could have (at a basic level used in reverse proxy mode - obviously, the IP addresses here are redacted and replaced with fakes). We assume you have created an A record in your DNS called “proxy” which resolves to 192.206.28.1, so fully qualified, will be proxy.sudonix.org in this case.

    The web browser requests this site, which is in turn received by NGINX and matches the below config

    server { server_name proxy.sudonix.org; listen 192.206.28.1; root /home/sudonix.org/domains/proxy.sudonix.org/ogproxy; index index.php index.htm index.html; access_log /var/log/virtualmin/proxy.sudonix.org_access_log; error_log /var/log/virtualmin/proxy.sudonix.org_error_log; location / { proxy_set_header Access-Control-Allow-Origin *; proxy_set_header Host $host; proxy_pass http://localhost:2000; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Api-Key $http_x_api_key; } location /images { index index.php index.htm index.html; root /home/sudonix.org/domains/proxy.sudonix.org/ogproxy; } fastcgi_split_path_info "^(.+\.php)(/.+)$"; listen 192.206.28.1:443 ssl http2; ssl_certificate /home/sudonix.org/domains/proxy.sudonix.org/ssl.combined; ssl_certificate_key /home/sudonix.org/ssl.key; }

    The important part here is server_name proxy.sudonix.org; as this is used to “map” the request to the actual domain name, which you can see in the root section as root /home/sudonix.org/domains/proxy.sudonix.org/ogproxy;

    As the DNS record you specified matches this hostname, NGINX then knows what to do with the request when it receives it.

    @Hari DDoS protection is not just a switch, or one component. It’s a collection of different and often disparate technologies that when grouped together form the basis of a combined toolset that can be used in defence.

    Typically these consist of IDS (Instrusion Detection System) and IPS (Intrusion Prevention System) components that detect irregularities in network traffic, and will take decisive action based on predefined rulesets, or in the case of more modern systems, AI and ML.

    Traditional “traffic shaping” technology is also deployed, so if an attack cannot be easily identified as malicious, the bandwidth available to that connection is severely limited to nothing more than a trickle rather than a full flow.

    Years ago, ISP’s used traffic shaping (also called “policers”) as an effective means of stopping applications such as BearShare, eDonkey, Napster, and other P2P based sharing systems from functioning correctly - essentially reducing the “appeal” of distributing and seeding illegal downloads. This was essentially the ISP’s way of saying “stop what you are doing please” without actually pulling the plug.

    These days, DDoS attacks are designed to overwhelm - not assume control of - webservers and other public facing components. It’s rare for small entities to be attacked unless there is some form of political agenda driven by your site or product. A classic example is governmental institutions or lawmakers who effectively are classed as “enforcers” and those who disagree are effectively making a statement in the form of Denial of Service.

    DDoS protection is effectively the responsibility of the hosting provider, but you shouldn’t just assume that they will protect you or your site. Their responsibility stops at their infrastructure, so it’s then up to you too decide how you full the gap in between your host and the website.

    Typically, you’d leverage something like Imunify360 which you can get for Plesk (and something I’d strongly recommend) but it’s not free, and is a paid (not expensive per month) subscription. If you want to use VirtualMin then there are a variety of tools readily available out of the box such as firewalls and fail2ban.

    @elhana-fine Yes that will happen of of course if you still choose to restart the NGINX service after making a change and the test fails. The test on it’s own will state the error and the line number allowing you to fix that first 🙂
