Hi all,
Sometimes our caching nameservers have trouble with mirror.centos.org. The reason is probably because pdns2.centos.org is down, and pdns3.centos.org is answering queries from the wrong ip-address it seems:
$ host -t NS mirror.centos.org
mirror.centos.org name server pdns2.centos.org.
mirror.centos.org name server pdns1.centos.org.
mirror.centos.org name server pdns3.centos.org.
$ host mirror.centos.org pdns1.centos.org.
Using domain server:
Name: pdns1.centos.org.
Address: 216.7.183.116#53
Aliases:
mirror.centos.org has address 216.7.183.116
$ host mirror.centos.org. pdns2.centos.org.
;; connection timed out; no servers could be reached
$ host mirror.centos.org. pdns3.centos.org.
;; reply from unexpected source: 63.135.110.10#53, expected 63.135.127.184#53
;; reply from unexpected source: 63.135.110.10#53, expected 63.135.127.184#53
;; connection timed out; no servers could be reached
The last one can easily be solved by setting local-address.
Hope this info is useful to anyone.
