Description Dave Jones 2007-11-16 16:46:33 UTC

so far this morning, I have 1792 messages like the following in my logs..

How do I fix / disable this ?

oddly, all the hostnames it complains about resolve just fine when run with
'host' from the command line.

Comment 1 Adam Tkac 2007-11-19 10:02:54 UTC

Specify "edns no" option in options statement. But real problem is usually
broken firewall or router which blocks big ( > 512b) packets. I recommend you
try edns-udp-size 512; option and if your log also has many messages
"..disabling EDNS" complete disable it.
