You might run some websites behind Nginx on Debian 12 and you might find yourself wanting to block requests from Russian IPs. It's trivial. # apt install libnginx-mod-http-geoip # echo "geoip_country /usr/share/GeoIP/GeoIP.dat;" > /etc/nginx/conf.d/geoip.conf # cat << EOF > /etc/nginx/cc-block.conf if ( $geoip_country_code3 = "RUS") { rewrite / /block-russia ; } location /block-russia { default_type text/plain ; return 200 'Russian IPs are blocked here, due to your unjust and unprovoked War against Ukraine.'
