[SOLVED] Configuring PDNSD - starts but doesn't cache

Since my pc is connected to lan that is barely usable because there are too many devices and network administration is next to none, I thought I could make it a bit better using pdnsd.

It starts (checked with systemctl status), but it doesn't cache anything.

Output of drill (used for testing):

Error: error sending query: Could not send or receive, because of network error

Output of joutnal:

$ journalctl -f _SYSTEMD_UNIT=pdnsd.service

Here's my configuration file:

Quick edit:
I read wiki, and man page but can not figure out what is wrong here.

Re: [SOLVED] Configuring PDNSD - starts but doesn't cache

Here’s what my config looks like:

global {
	perm_cache=1024;
	cache_dir="/var/cache/pdnsd";
#	pid_file = /var/run/pdnsd.pid;
	run_as="pdnsd";
	server_ip = 127.0.0.1;  # Use eth0 here if you want to allow other
				# machines on your network to query pdnsd.
	status_ctl = on;
#	paranoid=on;       # This option reduces the chance of cache poisoning
	                   # but may make pdnsd less efficient, unfortunately.
	query_method=udp_tcp;
	min_ttl=8h;       # Retain cached entries at least 15 minutes.
	max_ttl=1w;        # One week.
	timeout=10;        # Global timeout option (10 seconds).
	neg_domain_pol=on;
	udpbufsize=1024;   # Upper limit on the size of UDP messages.

	# https://wiki.archlinux.org/index.php/Pdnsd
	neg_rrs_pol=on;
	par_queries=2;
}

server {
	label="google";
	ip = 8.8.8.8;
	proxy_only=on;
	timeout=4;
	uptest=none;
	purge_cache=off;
}

server {
	label="google";
	ip = 8.8.4.4;
	proxy_only=on;
	timeout=4;
	uptest=none;
	purge_cache=off;
}

source {
	owner=localhost;
#	serve_aliases=on;
	file="/etc/hosts";
}

rr {
	name=localhost;
	reverse=on;
	a=127.0.0.1;
	owner=localhost;
	soa=localhost,root.localhost,42,86400,900,86400,86400;
}

(I have removed all commented blocks.)

Can you ping the DNS you have configured, or other servers, when you get that error?

I used your config as a tamplate. Than all that was needed was dns configuration. Everything works.

Re: [SOLVED] Configuring PDNSD - starts but doesn't cache

Great

In reality I don’t use 2 Google DNS’s; I used namebench to select the fastest servers and have more than two listed in my config, in addition to my provider’s ones.
