dproxy is a small caching name server (DNS) for use between Local Area Networks and the Internet.

Here are some key features of "dproxy":

small size: less than 3000 lines of code, ~25KB binary
modest resource requirements (runs great on an old 486)
discovers and serves names from /etc/hosts and dhcp lease files
human readable/editable ASCII text cache file
drops root priveledges early after startup

dproxy was initially written when Netscape Navigator 4 was the only browser availble for Linux, and BIND was a bloated beast with many security issues (is it still?).

Unfortunately Netscape 4 had an annoying bug where it would lockup and eat all your CPU while it was attempting to resolve a name. This would happen whenever your PPP dialup connection would drop.

Without the source code to Navigator, all I could do was write some software that always replied promptly to Netscape. dproxy was written to run on dial-up gateway machines and behave nicely when the gateway was not connected.

So it turns out that a few years later ADSL and WIFI are all the rage and many embedded routers run Linux. Most need some basic DNS support that doesn't consume much flash space. dproxy becomes useful once more.

What's New in This Release:

proper config file support
deny file support to help filtering add/spam
better install support
bug fixes
