dprox

dprox is a lightweight DNS proxy server. It's created as a drop-in replacement of dnsmasq to work with dnsmasq-china-list, while improving the overall lookup performance over large domain list.

Installation

dprox should build and work on all unix-like OS with ghc support, but it's only been tested on Linux and macOS.

While dprox can be built with cabal like any other Hackage packages, for a reliable compilation with pinned dependencies, stack is generally recommended.

stack setup
stack install

For Arch Linux users, an AUR package is provided. Alternatively, you also can use the statically linked binary for the latest release.

Usage

Only a small subset of dnsmasq options are implemented at the moment, just barely enough to work with dnsmasq-china-list and hosts-blocklists.

Here is the list of implemented dnsmasq options (with server, local, address and bogus-nxdomain options allowed in configuration file):

-u, --user=<username>
-p, --port=<port>
-a, --listen-address=<ipaddr>
-C, --conf-file=<file>
-h, --no-hosts
-H, --addn-hosts=<file>
-S, --local, --server=[/<domain>/]<ipaddr>[#<port>]
-A, --address=[/<domain>/]<ipaddr>
-B, --bogus-nxdomain=<ipaddr>

Use dprox --help or dnsmasq manpage for further details about these options. But be aware that there might be minor differences on some options like --server.

To use dprox with dnsmasq-china-list, with "8.8.4.4" as the remote DNS server (systemd user can also use this unit file):

dprox -C /etc/dnsmasq.d/accelerated-domains.china.conf -C /etc/dnsmasq.d/bogus-nxdomain.china.conf -S 8.8.4.4

To use dprox with hosts-blocklists and the default remote DNS server ("8.8.8.8"), without loading system hosts file:

dprox -C /opt/hosts-blocklists/domains.txt -H /opt/hosts-blocklists/hostnames.txt -h

Known Issue

• dprox has fairly large memory footprint at the moment. About 85MB for current dnsmasq-china-list.
