Configure dqcache


#under root - create dqcache root directory
mkdir -p /var/dqcache/root/servers /var/dqcache/env

echo 127.0.0.1 > /var/dqcache/env/IP
echo "/var/dqcache/root" > /var/dqcache/env/ROOT

#under root - setup dqcache root servers

) > /var/dqcache/root/servers/@'

#under root - create dqcache user
useradd dqcache


Run dqcache


#under root - run dqcache server
envuidgid dqcache envdir /var/dqcache/env dqcache

Run dqcache under daemontools

Here's a run file for dqcache, under daemontools:

#!/bin/sh
exec 2>&1
exec envuidgid dqcache envdir /var/dqcache/env dqcache

Here's a run file for logging, under the user dqcachelog:

#!/bin/sh
#exec setuidgid dqcachelog multilog t ./main
exec setuidgid dqcachelog multilog t '-*' '+* tx*+*' ./main

I personally don't want to log every query. The above just logs DNSCurve queries.
