# primecoin-seeder primecoin-seeder is a crawler for the Primecoin network, which exposes a list of reliable nodes via a built-in DNS server. Features: * regularly revisits known nodes to check their availability * bans nodes after enough failures, or bad behavior * accepts nodes down to v0.5.4 to request new IP addresses from, but only reports good post-v0.5.4 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 96 threads simultaneously). Dependencies & building on Ubuntu Linux: sudo apt install libboost-all-dev libssl-dev make ## USAGE Assuming you want to run a dns seed on dnsseed.example.com, you will need an authorative NS record in example.com's domain record, pointing to for example vps.example.com: $ dig -t NS dnsseed.example.com ;; ANSWER SECTION dnsseed.example.com. 86400 IN NS vps.example.com. On the system vps.example.com, you can now run dnsseed: ./dnsseed -h dnsseed.example.com -n vps.example.com If you want the DNS server to report SOA records, please provide an e-mailadres (with the @ part replaced by .) using -m. ## RUNNING AS NON-ROOT Typically, you'll need root privileges to listen to port 53 (name service). One solution is using setcap (Linux only) to give the executable permission to use a privileged port: sudo setcap 'cap_net_bind_service=+ep' ./dnsseed
