From: Paul A Vixie <paul@vix.com>
folks who wanted to know how to test whether their server is corrupt: dig www.networksolutions.com a @204.152.187.11 | grep 128.9.160.28 (204.152.187.11 is my local caching server, which isn't corrupt, dammit.) if the above command produces an A RR as output, your server is corrupt. folks who wanted to know how to dump their cache and look for this data: su ndc dumpdb awk '/^\$ORIGIN/ { o=$2 } /128.9.160.28/ {print o;print}' \ /var/named/named_dump.db (this assumes that you're using sh or csh, and that your named.conf's "directory" option is set to /var/named as mine is.) if the above command shows an origin other than icann.org, or shows more than one origin, you have caught something that i would like to see in my inbox -- and thanks!
