DNS Reference

This section includes tables of the files, daemons, and commands that are associated with the DNS service. In addition, a table of some of the flags that are used when the ISC version of BIND was built is included.

DNS Files

The following table describes the files that are associated with the DNS service.

Table 3-1 DNS Files

File Name	Function
`/etc/named.conf`	Provides configuration information for the `named` daemon. See the `named.conf`(4) man page for more information.
`/etc/rndc.conf`	Provides configuration information for the `rndc` command. See the `rndc.conf`(4) man page for more information.

DNS Commands and Daemons

The following table describes the commands and daemons that are associated with the DNS service.

Table 3-2 DNS Commands and Daemons

File Name	Function
`/usr/bin/dns-sd`	Finds or lists resources used by the mDNS service. See the `dns-sd`(1M) man page for more information.
`/usr/sbin/dig`	Requests DNS responses from a DNS server. Often used to troubleshoot. See the `dig`(1M) man page for more information.
`/usr/sbin/dnssec-dsfromkey`	Generates a DS RR from a key file. See the `dnssec-dsfromkey`(1M) man page for more information.
`/usr/sbin/dnssec-keyfromlabel`	Retrieves selected keys from cryptographic device and builds a key file. See the `dnssec-keygen`(1M) man page for more information.
`/usr/sbin/dnssec-keygen`	Creates keys and key files for secure DNS and for transaction signatures (TSIG). See the `dnssec-keygen`(1M) man page for more information.
`/usr/sbin/dnssec-signzone`	Signs a DNS zone. See the `dnssec-signzone`(1M) man page for more information.
`/usr/sbin/host`	Performs simple DNS lookups, often converting host names to IP addresses or IP addresses to host names. See the `host`(1M) man page for more information.
`/usr/sbin/named`	DNS server daemon, which responds to information requests from clients. See the `named`(1M) man page for more information.
`/usr/sbin/named-checkconf`	Checks the syntax of the `named.conf` file. See the `named`(1M) man page for more information.
`/usr/sbin/named-checkzone`	Checks the syntax and integrity of a DNS zone file. See the `named-checkzone`(1M) man page for more information.
`/usr/sbin/named-compilezone`	Converts a DNS zone file. See the `named-compilezone`(1M) man page for more information.
`/usr/sbin/nscfg`	Legacy name service configuration utility, which imports or exports `resolv.conf` content from the SMF repository. See the `nscfg`(1M) man page for more information.
`/usr/sbin/nslookup`	Deprecated: Queries the DNS server. Instead use the `dig` command.
`/usr/sbin/nsupdate`	Submits DNS update requests to a DNS server. See the `nsupdate`(1M) man page for more information.
`/usr/sbin/rndc`	Provides remote control of the DNS server daemon. See the `rndc`(1M) man page for more information.
`/usr/sbin/rndc-confgen`	Generates configuration files for the `rndc` command. See the `rndc-confgen`(1M) man page for more information.

Compilation Flags Used When BIND Was Built

You can view the flags that were used to compile BIND by using the named -V command. This table shows some of the compilation flags that were used when building the ISC version of BIND for the Oracle Solaris 11 release.

Table 3-3 BIND Compilation Flags

Flag Name	Function
`with-openssl`	Builds BIND with cryptographic and Secure Sockets Layer (SSL) support, which is required for DNSSEC
`enable-threads`	Enables multithreading
`enable-devpoll`	Uses the `/dev/poll` driver for fast poll on many file descriptors
`disable-openssl-version-check`	Disables the OpenSSL version check because OpenSSL is provided by a separate dynamic library
`enable-fixed-rrset`	Enables fixed resource record set ordering, which is needed for backward compatibility
`with-pkcs11`	Enables the use of OpenSSL cryptographic hardware support
