"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,

(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|

stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||

|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|

|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or

|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|

8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability

# 基础框架:
|
||||
|
||||
以下内容均在start.php中编写
|
||||
|
||||
请在start.php中写入:
|
||||
#### 1.监听端口
|
||||
|
||||
```php
|
||||
<?php
|
||||
@ -125,420 +36,69 @@ require_once __DIR__ . '/vendor/autoload.php';
|
||||
|
||||
$worker = new Worker('Dns://0.0.0.0:53');
|
||||
$worker->transport = 'udp';
|
||||
$worker->onMessage = function($connection, $data){
|
||||
$data=json_decode($data);
|
||||
$type=$data->type; #查询类型
|
||||
$name=$data->name; #查询内容(一般是域名,PTR时为倒序IP)
|
||||
$rip=$connection->getRemoteIp(); #客户端IP
|
||||
if(isset($data->addR->csubnet->ip)){
|
||||
$ip=$data->addR->csubnet->ip;
|
||||
}else{
|
||||
$ip=$rip;
|
||||
}
|
||||
# 请在下方编写您的DNS响应
|
||||
#——————————————————————
|
||||
|
||||
#——————————————————————
|
||||
#下方内容无需更改
|
||||
$send['id']=$data->id;
|
||||
$send['query']=$data->query;
|
||||
if(!isset($send['ttl'])){
|
||||
$send['ttl']=0;
|
||||
}
|
||||
$send['info']=json_encode(['domain'=>$data->name,'querytype'=>$data->type,'answertype'=>$send['type'],'ip'=>$ip,'rip'=>$rip,'ttl'=>$send['ttl'],'detail'=>$send['detail']]);
|
||||
$send=json_encode($send);
|
||||
$connection->send($send);
|
||||
};
|
||||
Worker::runAll();
|
||||
|
||||
```
|
||||
|
||||
### 请求变量
|
||||
|
||||
| 变量名称 | 意义 | 示例 |
|
||||
| --- | --- | --- |
|
||||
| $type | 请求类型 | A |
|
||||
| $name | 请求域名 | dnsservertest.com |
|
||||
| $rip | 客户端IP | 192.168.1.1 |
|
||||
| $data->id | 请求ID | 0001 |
|
||||
| $data->traffic | 请求包大小(Byte) | 88 |
|
||||
|
||||
# 编写响应:
|
||||
|
||||
### 响应参数
|
||||
|
||||
您最终需要回复一个$send的数组。定义如下:
|
||||
|
||||
| 名称 | 意义 | 类型 | 示例 | 说明 |
|
||||
| --- | --- | --- | --- | --- |
|
||||
| $send['type'] | 响应类型 | 字符串 | $send['type']=A | 指定响应的类型 |
|
||||
| $send['detail'] | 响应内容 | 字符串、数组、多维数组 | 119.29.29.29或$send['detail'][1]='119.29.29.29'或$send['detail']= array(); | 根据不同的响应类型,返回不同的响应。具请往下阅读各种记录的响应方式 |
|
||||
| $send['ttl'] | TTL缓存时间 | 数字 | $send['ttl']=600 | 并非所有记录都需要TTL,未传入时默认0 |
|
||||
| $send['flag'] | Flag类型 | 字符串 | $send['flag']=‘REFUSE’ | 使用flag类型时需指定的flag |
|
||||
| $send['id'] | ID | 数字 | 0001 | 无需更改无需编写。 |
|
||||
| $send['query'] | 请求体 | 16进制 | | 无需更改无需编写。 |
|
||||
| $send['info'] | 请求和响应信息 | json | | 无需编写,基础框架内已经完成。 |
|
||||
|
||||
您应当根据$name变量,进行响应。
|
||||
|
||||
以下内容请在start.php结构中间的空行内编写:
|
||||
|
||||
### A记录:
|
||||
|
||||
响应一个或多个IPv4地址
|
||||
|
||||
$send['detail']应为一个数组。
|
||||
#### 2.获取查询内容
|
||||
|
||||
```php
|
||||
$send['type']='A';
|
||||
$send['detail'][1]='119.29.29.29';
|
||||
$send['detail'][2]='8.8.8.8';
|
||||
$send['ttl']=30;
|
||||
```
|
||||
|
||||
以上意味着响应IP为119.29.29.29和8.8.8.8,指定TTL为30秒。
|
||||
|
||||
- 示例
|
||||
|
||||
```php
|
||||
<?php
|
||||
use Workerman\Worker;
|
||||
use Workerman\Connection\TcpConnection;
|
||||
use Workerman\Protocols\Http\Request;
|
||||
require_once __DIR__ . '/php-ipv6.php'; #IPv6支持
|
||||
require_once __DIR__ . '/vendor/autoload.php';
|
||||
|
||||
$worker = new Worker('Dns://0.0.0.0:53');
|
||||
$worker->transport = 'udp';
|
||||
$worker->onMessage = function($connection, $data){
|
||||
$data=json_decode($data);
|
||||
$type=$data->type; #查询类型
|
||||
$name=$data->name; #查询内容(一般是域名,PTR时为倒序IP)
|
||||
$rip=$connection->getRemoteIp(); #客户端IP
|
||||
|
||||
if($type=='A' && $name=='dnsservertest.com'){
|
||||
$send['type']='A';
|
||||
$send['detail'][1]='192.168.2.1';
|
||||
$send['detail'][2]='192.168.2.2';
|
||||
$send['detail'][3]='192.168.2.3';
|
||||
$send['ttl']=60;
|
||||
}
|
||||
#输出信息
|
||||
echo "\n Type:$type \n Domain: $name\n Client IP: $rip \n";
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
#### 3.响应A记录
|
||||
|
||||
```php
|
||||
$worker->onMessage = function($connection, $data){
|
||||
|
||||
$send['type']='A';
|
||||
$send['detail'][1]='119.29.29.29'; #第一条记录
|
||||
$send['detail'][2]='8.8.8.8'; #第二条记录
|
||||
$send['ttl']=30;
|
||||
|
||||
|
||||
|
||||
#id和query一般情况下直接返回输出即可
|
||||
$send['id']=$data->id;
|
||||
$send['query']=$data->query;
|
||||
if(!isset($send['ttl'])){
|
||||
$send['ttl']=0;
|
||||
}
|
||||
$send['info']=json_encode(['domain'=>$data->name,'querytype'=>$data->type,'answertype'=>$send['type'],'ip'=>$rip,'ttl'=>$send['ttl'],'detail'=>$send['detail']]);
|
||||
|
||||
|
||||
|
||||
$send=json_encode($send);
|
||||
$connection->send($send);
|
||||
|
||||
|
||||
};
|
||||
Worker::runAll();
|
||||
```
|
||||
|
||||
以上代码意味着对于dnsservertest.com域名的A记录请求,响应192.168.2.1、2.2、2.3三个IP,指定TTL为60秒。
|
||||
#### 4.响应其他记录
|
||||
|
||||
以下内容将不再给出完整代码示例。
|
||||
见start.php 内有所有记录类型的响应方式
|
||||
|
||||
### AAAA记录
|
||||
#### 5.说明
|
||||
|
||||
AAAA记录响应一个或多个IPv6地址。
|
||||
您应当通过获取query的 `$name`通过查询数据库等方式返回数据,对于不存在的记录应当返回SOA记录
|
||||
|
||||
```php
|
||||
$ipv6=new IPv6;
|
||||
$send['type']='AAAA';
|
||||
$send['detail'][1]=bin2hex($ipv6->ip2bin("fe80::2c5f")); #此操作可以还原被简化的IPv6地址 协议内不再对IPv6地址进行处理,请按照本方式传递16进制无":"的完整16位IPv6
|
||||
$send['detail'][2]=bin2hex($ipv6->ip2bin("2001:0:2851:b9d0:2c5f:f0d9:21be:4b96"));
|
||||
$send['ttl']=30;
|
||||
```
|
||||
您需要的时候可以通过 `dns_get_record()`向上级DNS递归查找并缓存
|
||||
|
||||
$send['detail']应当为数组,且值为完整的、没有‘:’的,连续16位16进制IPv6地址。
|
||||
这一系列操作,本协议不提供,您可以自行通过Redis等并利用workerman实现
|
||||
|
||||
IPv6库可以如上方示例所述,将IPv6还原完整并去除‘:’,再通过bin2hex的php函数转为16进制
|
||||
不建议作为根域名的NS服务器使用。
|
||||
|
||||
### CNAME
|
||||
## 已知问题
|
||||
|
||||
CNAME即别名,将映射到另一个或多个DNS域名,客户端将向另一个域名发送请求。
|
||||
本协议最早写于鄙人刚学习php的阶段,现在翻出来无疑是屎山一坨,代码写的和xxs一样,性能不敢测试,还请各位大佬包容
|
||||
|
||||
```php
|
||||
$send['type']='CNAME'
|
||||
$send['detail'][1]='hk.dnsservertest.com';
|
||||
$send['detail'][2]='jp.dnsservertest.com';
|
||||
$send['ttl']=600;
|
||||
```
|
||||
目前已知问题是:
|
||||
|
||||
$send['detail']一样为数组。
|
||||
|
||||
一般情况下,为了提升DNS解析效率,DNS服务器将同时直接返回一个A或AAAA记录,要实现这个请使用CNAME+A或CNAME+AAAA类型
|
||||
|
||||
### CNAME+A/AAAA
|
||||
|
||||
```php
|
||||
#CNAME+A
|
||||
$send['type']='CNAME+A';
|
||||
$send['detail']='ipv4.dnsservertest.com';
|
||||
$send['ttl']=30;
|
||||
|
||||
#CNAME+AAAA
|
||||
$send['type']='CNAME+AAAA';
|
||||
$send['detail']='ipv6.dnsservertest.com';
|
||||
$send['ttl']=30;
|
||||
```
|
||||
|
||||
CNAME+A和CNAME+AAAA的情况下,均只支持返回一条CNAME.
|
||||
|
||||
因此,此时的$send['detail']应当为字符串
|
||||
|
||||
如多条CNAME的均衡负载请通过您的代码在服务端实现。
|
||||
|
||||
WorkermanDNS将自动获取对应的A记录并返回。
|
||||
|
||||
### TEXT(TXT)
|
||||
|
||||
TEXT记录将返回一条文本记录。由于默认的最大包大小为512B,因此应当控制TEXT记录内容在256B之内
|
||||
|
||||
```php
|
||||
$send['type']='TEXT';
|
||||
$send['detail'][1]='text1-test';
|
||||
$send['detail'][2]='text2-test';
|
||||
$send['ttl']=600;
|
||||
```
|
||||
|
||||
$send['detail']为数组。值为TEXT记录内容(字符串)
|
||||
|
||||
### MX
|
||||
|
||||
MX邮件交换记录,建设邮箱时常用。
|
||||
|
||||
```php
|
||||
$send['type']='MX';
|
||||
$send['detail'][1]['name']='mx.zoho.com';
|
||||
$send['detail'][1]['pre']='20'; #权重
|
||||
$send['detail'][2]['name']='mx2.zoho.com';
|
||||
$send['detail'][2]['pre']='30'; #权重
|
||||
$send['detail'][3]['name']='mx3.zoho.com';
|
||||
$send['detail'][3]['pre']='50'; #权重
|
||||
$send['ttl']=600;
|
||||
```
|
||||
|
||||
$send['detail']为数组,其中的每个元素也是多维数组,分别有name和pre两个参数,分别为MX的记录值和对应权重。
|
||||
|
||||
### NS
|
||||
|
||||
将子域名转交给其他DNS服务器解析。
|
||||
|
||||
```php
|
||||
$send['type']='NS';
|
||||
$send['detail'][1]='coco.bunny.net';
|
||||
$send['detail'][2]='kiki.bunny.net';
|
||||
$send['ttl']=600;
|
||||
```
|
||||
|
||||
$send['detail']为数组,值为DNS服务器名称。
|
||||
|
||||
### SOA
|
||||
|
||||
SOA有自动和手动两种
|
||||
|
||||
- 自动
|
||||
|
||||
```php
|
||||
$send['type']='SOA';
|
||||
$send['detail']= array();
|
||||
$send['detail']['type']='auto';#自动获取上级的SOA
|
||||
$send['detail']['name']="$name";
|
||||
```
|
||||
|
||||
自动则指定 $send['detail']['type']='auto' ,将自行从上级DNS服务器获取SOA信息。以上代码无需改动,直接使用即可。
|
||||
|
||||
- 手动
|
||||
|
||||
```php
|
||||
$send['type']='SOA';
|
||||
$send['detail']= array();
|
||||
$send['detail']['type']='self';
|
||||
$send['detail']['mname']='dns31.hichina.com'; #主DNS服务器名
|
||||
$send['detail']['rname']='hostmaster.hichina.com'; #DNS管理员邮箱
|
||||
$send['detail']['serial']='2022052002'; #序列号 序列号必须递增 类似于dns记录的版本号 序列号变大时递归dns将更新记录
|
||||
$send['detail']['refresh']='3600'; #区域应当被刷新前的时间间隔
|
||||
$send['detail']['retry']='1200'; #刷新失败重试的时间间隔
|
||||
$send['detail']['expire']='86400'; #规定在区域不再是权威的之前可以等待的时间间隔的上限
|
||||
$send['detail']['minimum-ttl']='60'; #最小TTL
|
||||
$send['ttl']='180'; #当前SOA记录的TTL
|
||||
```
|
||||
|
||||
示例和说明如上。不推荐使用,因为SOA记录的错误可能对递归DNS造成极大影响,除非是您使用WorkermanDNS作为权威DNS时(请尽可能不要这么做)
|
||||
|
||||
### None
|
||||
|
||||
none是WorkermanDNS自定义的一种方式。将返回NXDOMAIN状态码以及SOA记录,一般用于域名不存在时。同样,SOA部分也可以使用自动和手动两种。
|
||||
|
||||
```php
|
||||
$send['type']='none';
|
||||
$send['detail']= array();
|
||||
$send['detail']['type']='auto';
|
||||
$send['detail']['name']="$name";
|
||||
```
|
||||
|
||||
```php
|
||||
$send['type']='none';
|
||||
$send['detail']= array();
|
||||
$send['detail']['type']='self';
|
||||
$send['detail']['qname']='phpisthebestlanguage.com';#根域名
|
||||
$send['detail']['mname']='dns31.hichina.com'; #主DNS服务器名
|
||||
$send['detail']['rname']='hostmaster.hichina.com'; #DNS管理员邮箱
|
||||
$send['detail']['serial']='2022052002'; #序列号 序列号必须递增 类似于dns记录的版本号 序列号变大时递归dns将更新记录
|
||||
$send['detail']['refresh']='3600'; #区域应当被刷新前的时间间隔
|
||||
$send['detail']['retry']='1200'; #刷新失败重试的时间间隔
|
||||
$send['detail']['expire']='86400'; #规定在区域不再是权威的之前可以等待的时间间隔的上限
|
||||
$send['detail']['minimum-ttl']='600'; #最小TTL
|
||||
$send['ttl']='180'; #当前TTL
|
||||
```
|
||||
|
||||
### Flag
|
||||
|
||||
Flag类型将返回DNS状态码。
|
||||
|
||||
- NXDOMAIN
|
||||
|
||||
```php
|
||||
$send['type']='flag';
|
||||
$send['flag']='NXDOMAIN';
|
||||
```
|
||||
|
||||
NXDOMAIN表示域名不存在,使用flag类型返回NXDOMAIN时不会附带SOA,当作为权威DNS时可能造成LDNS发生错误,不建议使用,建议使用none类型替代
|
||||
|
||||
- SERVFAIL
|
||||
|
||||
```php
|
||||
$send['type']='flag';
|
||||
$send['flag']='SERVFAIL';
|
||||
```
|
||||
|
||||
SERVFAIL表示解析遇到错误,类似于HTTP的503
|
||||
|
||||
- REFUSE
|
||||
|
||||
```php
|
||||
$send['type']='flag';
|
||||
$send['flag']='REFUSE';
|
||||
```
|
||||
|
||||
REFUSE表示服务器拒绝此请求,可用于限定客户端的IP范围
|
||||
|
||||
|
||||
Flag类型无需返回$send['detail']
|
||||
|
||||
### Raw
|
||||
|
||||
Raw是WorkermanDNS自定义的一种类型,将不再处理,直接以16进制形式响应,从而无需进行16进制拼合,以加快响应速度。一般是在第一次响应完毕后通过截取记录和请求,写入缓存(如Redis或共享变量等),后续遇到相同请求且在TTL内直接返回。
|
||||
|
||||
```php
|
||||
$send['type']='raw';
|
||||
$status='8180';
|
||||
$questions='0001';
|
||||
$AnswerRRs='0001';
|
||||
$AuthorityRRs='0000';
|
||||
$AdditionalRRs='0000';
|
||||
$answer='c00c000c00010000001e001203646e73086c617973656e736503636f6d00';#此处示例为返回记录值为dns.laysense.com的PTR记录的16进制
|
||||
$response=$data->id.$status.$questions.$AnswerRRs.$AuthorityRRs.$AdditionalRRs.$data->query.$answer;
|
||||
$send['detail']=$response;
|
||||
```
|
||||
|
||||
# 流量统计与日志
|
||||
|
||||
### 响应(出站)
|
||||
|
||||
Dns.php文件中send函数下,将会返回提供$query和$info两个变量,以及$response。
|
||||
|
||||
`strlen($response)`将直接可以获取该次响应出站流量(为byte)
|
||||
|
||||
$query是请求包体的16进制响应内容
|
||||
|
||||
$info为一个json对象,var_dump结构类似如下
|
||||
|
||||
```php
|
||||
object(stdClass)#18 (6) {
|
||||
["domain"]=>
|
||||
string(26) "95.188.24.172.in-addr.arpa"
|
||||
["querytype"]=>
|
||||
string(3) "PTR"
|
||||
["answertype"]=>
|
||||
string(3) "PTR"
|
||||
["ip"]=>
|
||||
string(12) "172.24.176.1"
|
||||
["ttl"]=>
|
||||
int(30)
|
||||
["detail"]=>
|
||||
string(16) "dns.laysense.com"
|
||||
}
|
||||
```
|
||||
|
||||
以上是一个对172.24.188.95的IP地址提供值为dns.laysense.com的PTR记录的$info示例
|
||||
|
||||
包含了请求域名、请求类型、响应类型、客户端IP、ttl等,可供您进行日志统计
|
||||
|
||||
### 请求(入站)
|
||||
|
||||
请参看上方的请求变量章节。
|
||||
|
||||
其中对于流量将传递$data->traffic变量,其为请求包体的大小(Byte)
|
||||
|
||||
# EDNS Subnet IP
|
||||
|
||||
这是一个DNS协议的扩展。支持的递归DNS服务器会向权威DNS发送请求客户端的IP地址。
|
||||
|
||||
WorkermanDNS支持对该协议提供的IPv4进行解析。
|
||||
|
||||
通过我们在上述示例框架start.php中的代码:
|
||||
|
||||
```php
|
||||
if(isset($data->addR->csubnet->ip)){
|
||||
$ip=$data->addR->csubnet->ip;
|
||||
}else{
|
||||
$ip=$rip;
|
||||
}
|
||||
```
|
||||
|
||||
$ip参数将在支持EDNS SubnetIP的情况下优先使用SubnetIP,不存在时则使用连接到的对端IP。
|
||||
|
||||
对于写入后端记录时,rip与ip 参数都会始终提供。当不支持EDNS SubnetIP时,rip与ip相同。否则,ip是EDNS SubnetIP,rip是udp对端IP。
|
||||
|
||||
# 运行
|
||||
|
||||
使用
|
||||
|
||||
`php start.php start` 运行
|
||||
|
||||
`php start.php start -d` 后台运行,自带守护进程
|
||||
|
||||
`php start.php stop` 停止运行
|
||||
|
||||
`php start.php status` 查看运行状况
|
||||
|
||||
请注意:
|
||||
|
||||
DNS服务使用53端口,为特权端口,绝大多数情况下必须使用root权限运行。
|
||||
|
||||
