I understand the clients should not connect directly to the dnsseeder, I meant that the DNS seeder is not logging attempted connections or IP addresses from coin clients.
It is running as root and listening on port 53.
In the post above I showed you that I could not connect. Is the port 53 open in firewall?
Anyway, what 'dig @127.0.0.1 seed.cryptodistributed.org' does report being issued locally at this host?
