Bind slave server not updating Free chat with sexy woman no credit card required
Hi, I have a Master DNS server running on Windows 2008 and a Slave DNS server running BIND on Linux.
The slave successfully collects the zone files from the master server, and can serve dns lookup requests fine.
Each change means that zone data files must be modified. Or at least use a tool to increment the serial number for you.
The syntax of zone data files lends itself to making mistakes.
In the event that the Master server goes down, how can I ensure that the slave server keeps running, even when the zone files become old?
Read through explanations on the different SOA fields.However, recently the Master DNS server went down and I found that the slave also stopped working.When I run a test on the slave server using nslookup, it said server can't find SERVFAIL The zone TTL is very low (2 minutes) to ensure we can switch to a backup server quite quickly.When configuring BIND, all times are specified in seconds. However, it is possible to use abbreviations when specifying units of time other than seconds, such as minutes ( Seen individually, directives and resource records can be difficult to grasp. ( 2001062501 ; serial 21600 ; refresh after 6 hours 3600 ; retry after 1 hour 604800 ; expire after 1 week 86400 ) ; minimum TTL of 1 day IN NS dns1. Arnold, how would those settings ensure that any changes are updated instantly? Basically, SRVFAIL means server fail which is configurational error.We need a low TTL to ensure that any ip changes are relatively quick to ensure we can switch over to a backup application server when necessary. To check your file check the following command : named-checkconf /etc/Does it show any error?However, when placed together in a single file, they become easier to understand. The following example shows a very basic zone file. Resource records define the parameters of the zone and assign identities to individual hosts.Directives are optional, but resource records are required to provide name service to a zone.
