Bind updating outside zone sincere dating
From time to time, I write an article for the Oopsilon web site.
DNS performs IP address-to-name translation by manipulating the IP address and using reverse-mapped zones under the reserved domain name Now, by way of illustrating the sometimes confusing nature of the DNS, some organizations (especially smaller ones) elect to run both caching and authoritative functions in the same name server.Murphy and other elements of chaotic cosmic calamity.If the TCP/IP settings for a member computer specify the IP address of a public DNS server—perhaps at an ISP or DNS vendor or the company’s public-facing name server—the TCP/IP resolver won’t find Service Locator (SRV) records that advertise domain controller services, LDAP, Kerberos and Global Catalog.This happens because BIND is configured with a simple DNS zone, as follows: IN SOA adhocbox. ( 2008042701 ; Serial 28800 ; Refresh 14400 ; Retry 604800 ; Expire 86400 ) ; Minimum NS adhocbox. For external requests, the zone file above is sufficient: serving the external IP is what these clients will expect. A view can have any number of zones inside, but in this case I only need one zone in each.For internal requests, a seperate zone can be used: IN SOA adhocbox. ( 2008042701 ; Serial 28800 ; Refresh 14400 ; Retry 604800 ; Expire 86400 ) ; Minimum NS adhocbox. One this configuration has been put in place, its operation is automatic: anyone from the LAN will receive the LAN IP of the web server, and will be able to view the web site.
