System: CURRENT/r263263 Unbound: disabled (as far as I can tell) Nameservice: using bind99 from ports. This worked two days ago and then yesterday - blammo! This system is the default nameserver for the LAN, and queries from other clients seem to be accepted and answered. Only the machine itself is blind. Other independent network services seem unaffected, and I can telnet to port 53 on my ISP's public nameservers. Respectfully, Robert Huff
