This document outlines some peculiarities of Bind 9.3 in comparison with Bind 8.x.
- Bind 9.3 is started/stopped/restarted via hsphere-daemontools-0.76-1, the
package built on the basis of DJB daemontools.
This package is included into H-Sphere installation and is used with the
H-Sphere mail service package.
- The named daemon is administered by the rndc utility, not by ndc.
- ndc restart is no longer supported.
Since Bind 9.3, the Daemon Tools' svc utility is called in the named daemon
to stop, start and restart.
The procedure of stopping/starting/restarting named remains the same. However, you may
use Bind stop/start/restart using svc as an alternative:
Enter the /service directory:
This directory is used by daemontools and contains symlinks to standard service directories.
- To stop Bind, run:
/command/svc -kd named
- To start Bind, run:
/command/svc -u named
This sequence is equivalent to restarting named.
Bind includes a utility called rndc which allows you to use command line statements to administer the
named daemon, locally, or remotely.
Managing DNS Zones
1) To reload a DNS zone:
rndc reload <ZONE>
2) To reload all DNS zones:
After that, only changed zones will be reloaded.
3) To suspend updates to a dynamic zone:
rndc freeze <ZONE>
4) To enable updates to a frozen dynamic zone and reload it:
rndc thaw <ZONE>
Run rndc for more options.
rndc Config File
If rndc is unable to connect to named, check the /etc/rndc.conf and /etc/named.conf.
For details on rndc configuration, run:
It is strongly unrecommended to manually edit the configuration files, as it may lead to misconfiguration
in dynamic zone updates!
