such config is really baaaad idea.

Anyway, I would check these things: /etc/hosts -> ./inet/hosts /etc/inet/ipnodes -> ./hosts aka - are both flat files pointing on the same file in /etc/inet/hosts ----------- Mike DeMarco píše v pá 05. 11. 2010 v 10:12 -0700: > Even though nscd is running with the default ttl a ssh to the same > host within a minute is still going out and hitting DNS. > nscd is respecting DNS TTLs. Also check nscd.conf And use dtrace on nscd, check if nss_files functions are called and what they return.
