DNS (ii) Forward and backward parsing configuration and client query tools for Linux

First, the service installation:

1 , Bind Introduction:

Bind : Berkeley Internet Name Domain

www.isc.org

Package:

Bind : Bind application packages;

bind-utils : Client toolkit;

Service Program Name: named

2 , program installation:

# Yum Install bind: Installing bind;# rpm–ql Bind | Less: View the bind installation build file;

#/etc/rc.d/init.d/named: Service startup script; #/etc/named.conf: Service master profile; #/etc/named.rfc1912.zones: zone configuration file;

Second, the service configuration:

1 , master configuration file:

# vim /etc/named.conf> options    {    //Global Configuration;>      listen-on port53 { 127.0.0.1; };    // Listening port and IP, default to native only, note can listen to all IP port number 53rd;>     listen-on-v6port 53 { ::1;  };    //Note to listen for all IPV6 port 53rd;>     directory  "/var/ Named ";     //indicates the Zone profile directory;>     allow-query {  localhost; };    //access control, annotations allow all ip>     recursion  yes;    //whether recursive > };>> logging {    //configuration log information; > };>> zone  "."  in {    //Configuring the root zone;> };>> include  "/etc/ Named.rfc1912.zones ";     //read the domain file information;> include "/etc/named.root.key ";    &nbSP;//is related to remote control;

2 , zone configuration file:

# Vim/etc/named.rfc1912.zones: Add forward parsing region and reverse parsing region;

Forward parsing:

> Zone "chencer.org" in {> type master;    Indicates the parsing type (master|slave|hint|forward);> file "Chencer.org.zone"; Indicates the parse file, which is the relative path, which is the directory defined in the master configuration file/var/named/;>};

Reverse parsing:

> Zone "1.168.192.in-addr.arpa" in {> type master;> file "1.168.192.in-addr.arpa.zone";>};

3 , providing a parse library:

Forward Parsing Library:

# vim /var/named/chencer.org.zone>  $TTL  86400> @    in     soa    dns.chencer.org.    root.chencer.org.      (>     2015072201>     1D>      10m>     5d>     1d     ) > @      IN    NS     dns> @      IN    MX     10    mail> dns    in    a     192.168.1.10> www    IN    A     192.168.1.11> blog   IN    A     192.168.1.12> pop3   in    a    192.168.1.13> web     In    cname    www

Reverse Parse Library:

# vim /var/named/1.168.192.in-addr.arpa.zone>  $TTL  86400> @     IN    SOA    dns.chencer.org.     root.chencer.org.     (>     2015072201>      1D>     10M>     5D>      1D    ) > @     in    ns     dns.chencer.org.> 10    in    ptr     dns.chencer.org.> 11    in    ptr     www.chencer.org.> 12    in    ptr     blog.chencer.org.> 13    in    ptr     pop3.chencer.org.

Description

1, forward parsing and reverse parsing the names in the file can use only relative names, which are relative to the current region;

2, the absolute suffix can use $ORIGIN to define;

Modify the Parse library file group and permissions:

# chown root:named/var/named/chencer.org.zone# chown root:named/var/named/1.168.192.in-addr.arpa.zone# chmod 640/var /named/chencer.org.zone# chmod 640/var/named/1.168.192.in-addr.arpa.zone

Third, start the service:

# Service named Configtest: Check the configuration file syntax is wrong; # chkconfig named on: Set boot boot; # service named {Start|restart}: Start or restart the service; SS-TUNL | grep:53: View port 53rd for TCP and UDP, # RNDC Reload: Service needs to reload after the configuration file is modified in service startup;

Four, the client query tool;

# yum Install Bind-utils: The client needs to install the query tool package;

1 , Host :

# host-t Rrtype NAME [SERVER]-T rrtype: Specifies the resource record type (a| ns| soa| Mx| PRT); Name:ip or FQDN; server: Specify a DNS server;

2 , nslookup :

Interactive query tool:

# nslookup> Server ip:> set type={a| soa| ns| Mx}> NAME

3 , Dig :

# dig-t TYPE NAME @SERVER query option: +trace +notrace +recurse +norecurse

Forward parsing:

The test inverse does not use- t PTR, and the -x option is used ;
