Re: DNS server works but keep getting "host unreachable resolving" error

2009-09-21 Thread Shi Jin
Thank you all. I've confirmed that the problem is firewall related. I've replaced my current Untangle firewall with a simplest Linux NAT iptables firewall and everything works perfectly, without any complains. Thank you very much for your kind help/suggestions. Shi

bind-9.7.0a3 genkey.sh and dnssec-signzone missing check

2009-09-21 Thread Paul Wouters
Hi, When using 9.7.0a3 with dnssec-signzone and PKCS#11, one can use the genkey.sh as a tool to generate keys. It is however hardcoded to RSASHA1. (We needed NSECRSASHA1) The below tiny patch addresses this. Related, the dnssec-signzone command created a zone with algo 5 DNSKEY's with NSEC3 re

1) Confirm whether you need to forward at all. If you don't need to, then remove the forwarders entries and that should take care of the errors in your log. 2) If you *must* use forwarders, look at the part of the config that you didn't show us, and determine whether there is something there (e.

Re: Need help on delegation to subdomain/external servers

2009-09-21 Thread Kevin Darcy
What is "unfortunate" about BIND picking a forwarder based on real, up-to-date information about the thing that the end-user ultimately cares about -- how quickly the queries get answered? Surely this is better than hardcoding a bunch of assumptions into your forwarding configs, assumptions th

Hi there, I've setup a DNS server running bind9 in my LAN and set it up to ISP provided DNS servers as the forwarders. Currently this DNS server works in the sense both internal and external names are resolved without any problem. However, for each DNS query, the syslog shows entries of dhcp-
