Onixcoin-seeder is a crawler for the Onixcoin network, which exposes a list
of reliable nodes via a built-in DNS server.

* regularly revisits known nodes to check their availability
* bans nodes after enough failures, or bad behaviour
* accepts nodes down to v0.3.19 to request new IP addresses from,
  but only reports good post-v0.3.24 nodes.
* keeps statistics over (exponential) windows of 2 hours, 8 hours,
  1 day and 1 week, to base decisions on.
* very low memory (a few tens of megabytes) and cpu requirements.
* crawlers run in parallel (by default 24 threads simultaneously).


$ sudo apt-get install build-essential libboost-all-dev libssl-dev


Assuming you want to run a dns seed on, you will
need an authorative NS record in's domain record, pointing
to for example

$ dig -t NS

;; ANSWER SECTION   86400    IN      NS

On the system, you can now run dnsseed:

./dnsseed -h -n

If you want the DNS server to report SOA records, please provide an
e-mail address (with the @ part replaced by .) using -m.

Compiling will require boost and ssl.  On debian systems, these are provided
by `libboost-dev` and `libssl-dev` respectively.

$ make

This will produce the `dnsseed` binary.


Typically, you'll need root privileges to listen to port 53 (name service).

One solution is using an iptables rule (Linux only) to redirect it to
a non-privileged port:

$ iptables -t nat -A PREROUTING -p udp --dport 53 -j REDIRECT --to-port 5353

If properly configured, this will allow you to run dnsseed in userspace, using
the -p 5353 option.
