Thanks, this got me started, but the results were negative. At least that is what I think "Bad cache" and "SERVFAIL cache' mean. So it seems it isn't actually working. The command is actually rndc dumpdb and redhat has specified a dumpfile in /etc/named.conf as /var/named/data/cache_dump.db Would cache entries have the URL name with the IP address? ; Start view _default ; ; ; Cache dump of view '_default' (cache _default) ; $DATE 20190701230228 ; ; Address database dump ; ; [edns success/4096 timeout/1432 timeout/1232 timeout/512 timeout] ; [plain success/timeout] ; ; ; Unassociated entries ; ; 192.58.128.30 [srtt 573690] [flags 00000000] [edns 0/3/3/3/3] [plain 0/19] [ttl 764] ; 198.41.0.4 [srtt 621280] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 192.203.230.10 [srtt 564510] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 2001:500:9f::42 [srtt 622890] [flags 00000000] [edns 0/1/1/1/1] [plain 0/18] [ttl 764] ; 192.33.4.12 [srtt 615460] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 202.12.27.33 [srtt 599290] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 2001:503:ba3e::2:30 [srtt 587160] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 199.9.14.201 [srtt 575540] [flags 00000000] [edns 0/2/2/2/2] [plain 0/19] [ttl 764] ; 2001:7fd::1 [srtt 613040] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 2001:500:2d::d [srtt 800870] [flags 00000000] [edns 0/1/1/1/1] [plain 0/18] [ttl 764] ; 2001:500:2f::f [srtt 619190] [flags 00000000] [edns 0/4/4/4/4] [plain 0/18] [ttl 764] ; 193.0.14.129 [srtt 565040] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 2001:500:200::b [srtt 595920] [flags 00000000] [edns 0/2/2/2/2] [plain 0/19] [ttl 764] ; 2001:500:1::53 [srtt 616240] [flags 00000000] [edns 0/2/2/2/2] [plain 0/17] [ttl 764] ; 2001:503:c27::2:30 [srtt 589830] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 198.97.190.53 [srtt 587370] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 192.5.5.241 [srtt 617730] [flags 00000000] [edns 0/3/3/3/3] [plain 0/19] [ttl 764] ; 192.36.148.17 [srtt 527000] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 199.7.83.42 [srtt 541770] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 2001:dc3::35 [srtt 626880] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 2001:500:2::c [srtt 594560] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 192.112.36.4 [srtt 601630] [flags 00000000] [edns 0/3/3/3/3] [plain 0/19] [ttl 764] ; 199.7.91.13 [srtt 619680] [flags 00000000] [edns 0/3/3/3/3] [plain 0/19] [ttl 764] ; 2001:7fe::53 [srtt 564980] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 2001:500:a8::e [srtt 594560] [flags 00000000] [edns 0/3/3/3/3] [plain 0/18] [ttl 764] ; 2001:500:12::d0d [srtt 621350] [flags 00000000] [edns 0/3/3/3/3] [plain 0/19] [ttl 764] ; ; Bad cache ; ; ; SERVFAIL cache ; ; ; Start view _bind ; ; ; Cache dump of view '_bind' (cache _bind) ; $DATE 20190701230228 ; ; Address database dump ; ; ; [edns success/4096 timeout/1432 timeout/1232 timeout/512 timeout] ; [plain success/timeout] ; ; ; Unassociated entries ; ; ; Bad cache ; ; ; SERVFAIL cache In the man page for named, it says It is not necessary to run named in a chroot environment if the Red Hat SELinux policy for named is enabled. When enabled, this policy is far more secure than a chroot environment. Users are recommended to enable SELinux and remove the bind-chroot package. How do I tell whether I am using a chroot or SELinux? _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
