Who do you use as your DNS provider? If you can switch to someone like OpenDNS (it’s free) they provide automatic (& very configurable) blocking of social networking sites, webmail, adult content etc. EDIT: You don’t have to change anything with your ISP either.
I don’t use analogies when I explain this concept to people I just try to make it as simple (without completely removing the true meaning behind it) as possible. I do work with a lot of small business owners; some are web savvy/smart, and others not so much. In each instance what I’ve had good … Read more
I tried to reproduce this on both Windows 2012 and Windows 2012 R2 but couldn’t get the same end result. I can confirm the initial validation error (An unknown error occurred while validating the server.), and I can see the strange query for . IN SOA, but clicking “OK” at that point appears to work … Read more
I’ve looked this up before, but I’m having trouble finding something better than this at the moment: https://lists.isc.org/pipermail/bind-users/2012-April/087455.html BIND8 and onward consider each of the forwarders begin with “equal weight”. Based on the SRTT of the responses, the nameserver begins to favor one over the other. A certain percentage of queries will always hit the … Read more
Both approaches are valid, do know that this record will not show as the originating address. When you send an email to one of your configured addresses, the sending MTA will look up the MX record configured for your domain. It will get the IP from that domain and it will open an SMTP session … Read more
Just to clarify, www.example.com is not the root of the domain, example.com is. A CNAME on www.example.com is valid, but a CNAME on example.com is not – cpanel is right to reject the attempt. A CNAME record can only exist on a name when no other record type exists for that name, since it indicates … Read more
Historically the root zone manager has taken updates from registrars through an e-mail template system. If you were messing about with NetSol 10+ years ago you’d remember the e-mail templates. As inherently stable and reliable as e-mail is, Verisign (NetSol at the time) came up with a new RZMS (Root Zone Management System) which is … Read more
While I still don’t know exactly why this happened (and would welcome explanations!) it seems to be fixed now. I went over the networking configuration with a fine tooth comb, and discovered to my chagrin that the default gateway had a typo in it!

You need to use views: view “officeA” { match-clients { 192.168.1.0/24; }; include “/etc/named.conf.zones-rfc1912”; include “/etc/named.conf.zones-common”; include “/etc/named.conf.zones-officeA”; }; view “officeB” { match-clients { 192.168.2.0/24; }; include “/etc/named.conf.zones-rfc1912”; include “/etc/named.conf.zones-common”; include “/etc/named.conf.zones-officeB”; };
No. You can’t be reasonably sure your outgoing email will be delivered, as many destinations simply blacklist, firewall, or even null route all major cloud providers’ IP blocks due to the heavy abuse seen from those ranges – not just from email but via other services as well. And even if your mail is delivered … Read more
