## 使用方法
|
|
||||||
|
|
||||||
### ビルド
|
|
||||||
|
|
||||||
```shell
|
|
||||||
go build
|
|
||||||
```
|
|
||||||
|
|
||||||
### 実行
|
|
||||||
|
|
||||||
```shell
|
|
||||||
export OPENGFW_LOG_LEVEL=debug
|
|
||||||
./OpenGFW -c config.yaml rules.yaml
|
|
||||||
```
|
|
||||||
|
|
||||||
#### OpenWrt

- `block`: 阻断连接，不再处理后续的包。
|
|
||||||
- `drop`: 对于 UDP，丢弃触发规则的包，但继续处理同一流中的后续包。对于 TCP，效果同 `block`。
|
|
||||||
- `modify`: 对于 UDP，用指定的修改器修改触发规则的包，然后继续处理同一流中的后续包。对于 TCP，效果同 `allow`。

# Analyzers
|
|
||||||
|
|
||||||
Analyzers are one of the main components of OpenGFW. Their job is to analyze a connection, see if it's a protocol they
|
|
||||||
support, and if so, extract information from that connection and provide properties for the rule engine to match against
|
|
||||||
user-provided rules. OpenGFW will automatically analyze which analyzers are referenced in the given rules and enable
|
|
||||||
only those that are needed.
|
|
||||||
|
|
||||||
This document lists the properties provided by each analyzer that can be used by rules.
|
|
||||||
|
|
||||||
## DNS (TCP & UDP)
|
|
||||||
|
|

For queries:
|
|
