Hello! I have a strange problem. My postfix does not resolve one of the IP address to domain name. So, in such case mail is dropped. Restarting the postfix does not help. host command from this OS resolves this IP correctly. I don't use any DNS server on this machine. Where can be a problem...

This how-to assumes that you are a somewhat experienced FreeBSD user, and understand how to use dd carefully to avoid data loss. It also assumes that you are able to restore your system to a working configuration if anything goes wrong. There is a Synopsis/Condensed Version below for the...

Searching this forum I've seen a number of ways to block youtube using ubound DNS. Problem is, it seems the methods are outdated. When I try the "local-zone "something" static" thing, I receive a syntax error upon trying restart the service. I'm on FreeBSD 11 and using dns/unbound. Can someone...

I'm just setting up an unbound server as a local resolver for our network. I'm not really seeing any actual issues but when running lookups from localhost, it's a bit disconcerting that the lookup sometimes hangs for over 10 seconds before finally returning a response. Even with the delay, the...

Hi all, I have been tasked with setting up a new server to replace a 10+ year old Apple Mac Server which has been running as the "Mainserver" for a small company I work at. This Mac server performs various server roles, including DHCP, DNS, and most importantly, file serving. We have roughly...

I have a vanilla 10.3 installation running inside VMWare Fusion Pro, on to which I installed Unbound. The object is to use this is a caching recursive DNS server. The IP bound to the NIC is 10.10.10.13. I can ping this from other hosts on the LAN without problem, and it also accepts remote SSH...

I have two BIND 9.10 servers set up with one as a master and the other as a slave. The master is in a jail on a FreeBSD 10.3 VM on Vultr and the slave is in a jail on a FreeBSD 10.3 VM on Digital Ocean. When I tried to switch them to doing Zone Transfers over IPv6 instead of IPv4 it stopped...

Hi folks! Four-year member, first-time poster here. I have been running some WordPress sites on a FreeBSD VPS off and on for a couple years. To do this I have just installed the basics: MySQL, PHP, WordPress, NGINX, etc. WordPress and FreeBSD have worked so well together after that, that I've...

In certain ISP crappy routers, the locally provided DNS resolver cannot handle DNSSEC and _srv queries, which breaks pkg at bootstrap, along with many other things. As these resolvers are handed out via DHCP from the router, I need to hard-code a specific forwarder and not have DHCP overwrite...

Hello, I'm looking for a good, stable DNS server with database (mysql) backend and web management interface (php based). I'm using now dns/powerdns and looking for alternative. Can you give me some advice? Thanks

Hello everyone, Is there a way we can redirect IPs not found on the access-control config?

Is there a way to restart unbound DNS service without flushing the cache? Or Is there a way to reload unbound DNS config without clearing the cache?

Hello, I've been searching on details about unbound's cached data and I couldn't really find a good info. Does anyone know a link or does anyone know about what data are being cached by unbound? Because one requirement for our DNS server is the user's privacy and we don't want to store any...

Ever faced an error like this? ping: cannot resolve example.com: Host name lookup failure It turns out that the problem was with unbound, I solved this problem on my laptop by disabling the validator module and removing its trust anchors...

Hi, I have an internal network with FreeBSD server with nginx and other programs running inside jails. I used to use Netgear DGN2200v3 router for internet connection and with the recent upgrade to NBN (Australian fiber network) I tried to use the Belkin AC1750DB (F9J1108v2), but the local...

I'm running a FreeBSD 10.1-RELEASE email server that uses unbound (from base system) as caching/forwarding DNS server. /etc/resolv.conf points to 127.0.0.1, and unbound config forwards to DNS servers on my LAN. Config is default. Almost any domain name will properly resolve: # drill...
