使用 go-conntrack 包来实现 conntrack 会话的创建和删除

package main

import (
    "fmt"
    "time"

    "github.com/florianl/go-conntrack"
)

func main() {
    // 创建 conntrack 客户端
    client, err := conntrack.Dial(nil)
    if err != nil {
        panic(err)
    }
    defer client.Close()

    // 创建 conntrack 对象
    ct, err := client.New()
    if err != nil {
        panic(err)
    }
    defer ct.Close()

    // 创建 conntrack 元组
    tuple := conntrack.Tuple{
        IPVersion: 4,
        Protocol:  conntrack.ProtocolUDP,
        OriginalSource: conntrack.Addr{
            IP:   [4]byte{127, 0, 0, 1},
            Port: 12345,
        },
        OriginalDestination: conntrack.Addr{
            IP:   [4]byte{127, 0, 0, 1},
            Port: 12346,
        },
    }

    // 创建 conntrack 属性
    attr := conntrack.Attribute{
        Type:  conntrack.AttrTimeout,
        Value: uint32(time.Second * 60 / time.Millisecond),
    }

    // 创建 conntrack 对象
    obj := conntrack.NewObject(tuple, attr)

    // 创建 conntrack 会话
    err = ct.Create(obj)
    if err != nil {
        panic(err)
    }

    fmt.Println("Conntrack session created")

    // 等待 5 秒钟
    time.Sleep(5 * time.Second)

    // 删除 conntrack 会话
    err = ct.Delete(obj)
    if err != nil {
        panic(err)
    }

    fmt.Println("Conntrack session deleted")
}
