    @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.

    Seems to be better with some scaling fix for redis on redis.conf. I haven’t seen the message yet since the changes I made

    # I increase it to the value of /proc/sys/net/core/somaxconn tcp-backlog 4096 # I'm uncommenting because it can slow down Redis. Uncommented by default !!!!!!!!!!!!!!!!!!! #save 900 1 #save 300 10 #save 60 10000

    If you have other Redis optimizations. I take all your advice

    @Hari said in Virtualmin Setup DigitalOcean:

    i have felt it is very hard to manage Virtualmin the settings are confusing

    It’s a bit of a learning curve, admittedly, but very powerful and easy to use provided you understand the implications of what you are doing. For example, moving a VirtualMin server to subserver and then back again without changing underlying components that rely on the correct placement of the server, of course it will no longer work.

    @gotwf said in Email issue (virturalmin):

    @jac Typically you want your domain’s MX records to point to FQDN server name, e.g. foo.example.eg

    % drill stockportcounty.fans mx ;; ->>HEADER<<- opcode: QUERY, rcode: NOERROR, id: 63911 ;; flags: qr rd ra ; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;; stockportcounty.fans. IN MX ;; ANSWER SECTION: stockportcounty.fans. 600 IN MX 10 stockportcounty.fans.

    Yours do not. Although a bit more drillin’ and reverse lookup indicates thusly;

    % drill stockportcounty.fans ;; ->>HEADER<<- opcode: QUERY, rcode: NOERROR, id: 160 ;; flags: qr rd ra ; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;; stockportcounty.fans. IN A ;; ANSWER SECTION: stockportcounty.fans. 600 IN A 65.108.63.35 ;; AUTHORITY SECTION: ;; ADDITIONAL SECTION: ;; Query time: 127 msec ;; SERVER: 204.8.232.207 ;; WHEN: Sun Oct 10 19:37:02 2021 ;; MSG SIZE rcvd: 54 <kvg@loon:~>% drill -x 65.108.63.35 ;; ->>HEADER<<- opcode: QUERY, rcode: NOERROR, id: 57802 ;; flags: qr rd ra ; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;; 35.63.108.65.in-addr.arpa. IN PTR ;; ANSWER SECTION: 35.63.108.65.in-addr.arpa. 86400 IN PTR vps.stockportcounty.fans.

    I think you probably want your mx record to point to vps.stockportcountry.fans.

    It is important for forward and reverse lookups for MX records jive. Maybe you are looking like a spammer in that they do not?

    Edit: But at least you have a reverse record, many spammers do not, so that is a big red flag.

    Thanks for the advice, will look into it all later once back home.
