Creating Bind DNS-Entries with regular dyndns-clients in routersview story

http://www.debian-administration.org – Recently there was a message posted upon the debian-user-german mailing list asking if there is a way to create BIND-compliant DNS-Updates with regulars dyndns-clients from routers. The Idea behind this is to get rid of dyndns.org services and provide an independent way to maintain dynamic dns entries for boxes without a static ip-address without the need of dyndns providers.

Providing a website search facility with the namazu indexerview story

http://www.debian-administration.org – Adding searching facilities to websites makes it a lot easier for finding content. When sites are dynamically constructed it is often simple to update the code to perform the searching in the application, but for sites constructed of static pages using an indexer such as namazu can give you a great interface in very short space of time.
