Introduction This setup codenamed „PMS“ (for PHP/MongoDB/Syslog) can be used to let one or more Syslog-servers write log messages to a MongoDB collection.

This is due to the […]
In my intranet, where hosts are in a subnet 192.168.2.0/24 and domain names in a domain mydomain, I use BIND9 as DNS, running on host intradns.mydomain , and NGINX as a webserver running on intraweb.mydomain. I would like to rewrite all subdomains of certain public domains (spammers and trackers) using my intranet DNS to a […]
