I am running OpenBSD 4.0 and 4.1 systems. On a standalone mail gateway
I have successfully deployed pdnsd as a local dns caching server.
However, on a company network I am having difficulty running this
daemon. Often the thing replies by stating that a domain exists but
does not give back A records. The visible symptom is no output to the
host command (recall that a non-existent domain will give output "not
found: 3(NXDOMAIN)"). Inspection of the cache confirms this (domain
resolves but A records). The key here is that this does not always
happen. We have been having trouble recently with our cisco router
supplied by the isp. We need to reset it occasionally. Is there any
way that this could be causing the trouble? I don't have enough
installations to test this hypothesis. Other than troubleshooting
help, what are other people using for dns caching?
Thank you,
Juan
