as the question asks, what are the roles in Bind9 for each of the following: bind9.service bind9-pkcs11.service bind9-resolvconf.service at bootup/startup, which one should be enabled? Also, if I am pointing A records at my debian server for websites, what happens if none of the above are running? could the following wordpress error on one of my websites (reported in another thread) be related..."Update Failed: Download failed. cURL error 6: Could not resolve host:..." sorry about mixing up threads...i am just not sure what is related and what is not, because i also get a warning "could not reliably determine hostname, using server1.<mydomain.com>" (which is actually the correct hostname as outlined in my etc/hosts file as posted on other thread on these forums)
Helpful reading material: https://wiki.debian.org/Bind9 Code: man -k pkcs11 I have used bind for tens of years, and have never bothered with bind9-pkcs11.service or bind9-resolvconf.service. Of those processes, I have only started or stopped bind9.service, or checked its status. This Tutorial contains info on testing name service is working: https://www.howtoforge.com/tutorial/setting-up-your-own-name-service-with-ispconfig/#nbsptesting If bind9.service is not running, name service queries go to the second name server. If also that is not running, hostnames do not resolve after caches expire, and you get Host foobar.tld not found: 3(NXDOMAIN).
ok so if i am using external registrar "A records" pointing at my webserver ipaddress for all domains on my server, i can completely disable bind9?
If you do not run name service on that host, I would remove bind9 completely. It is best to not have unnecessary services running.
