Yes, I seem to be learning that the hard way:) My shop is still on Bind 9.8.2 (Red Hat) on our authoritative servers. These new features in 9.11 are nice! On Fri, Sep 21, 2018 at 4:29 PM Reindl Harald wrote: > > Am 21.09.18 um 20:01 schrieb project722: > > Are you saying do a zone xfer then

Ok, is this something new to the later BIND versions? I'm looking on our authoritative servers running the red hat bind 9.8.2 and do not see any .jnl files. Also, I made a zone transfer and ran a dig axfr rpz-local @ipaddress and it returned the updated data, while the file remained unchanged.

Are you saying do a zone xfer then check the slave with the commands above to see what it actaully returns? Instead of checking the file itself? Sounds like to me you are saying that the server would return the updated data, because its in the journal file, regardless of whether its made it into

I've added those 2 lines to the master in the zone info section. It seemed to have helped with the delay with the server announcing the change and initiating the xfer-out. But the slave still takes @15 minutes for the new data to get populated in the file. On Fri, Sep 21, 2018 at 9:09 AM Reindl
