sshd, lookupd, reverse DNS
Authored by: sjk on Apr 03, '05 07:06:49PM
That might explain the "Apr 3 11:48:26 hostname sshd[1731]: reverse mapping checking getaddrinfo for failed - POSSIBLE BREAKIN ATTEMPT!" warnings from sshd even when reverse DNS is properly configured. But I don't see any way to configure lookupd to avoid that; it's currently using:
LookupOrder: Cache FF DNS NI DS
_config_name: Host Configuration
Another symptom is the who command (for instance) displaying the IP address for remote hostnames, while DNS PTR lookups return accurate data.

Anyone know what needs to be tweaked so address-to-name lookups will work properly, without creating static host entries, when DNS is verified as correctly configured?
