Dear Folks, Thank you for an excellent piece of software.
I am puzzled by the behaviour of our multi-level DNS system which answered many queries for names having shorter TTLs with SERVFAIL. By multilevel, I mean clients talk to one server, which forwards to another, and for some clients, there is a third level of caching. So it was unwise to add: serve-expired: "yes" cache-min-ttl: 30 to the server section of these DNS servers running unbound 1.6.8 on up to date RHEL 7? Please could anyone cast some light on why this was so? I will be spending some time examining the cause. If you need more information, please let me know. -- Nick Urbanik http://nicku.org [email protected] GPG: 7FFA CDC7 5A77 0558 DC7A 790A 16DF EC5B BB9D 2C24 ID: BB9D2C24
