NrppaMsg的initiating信令报文每字节的含义

NrppaMsg是5G协议中与NRPPA（New Radio PDCP Protocol Accelerator）相关的消息类型，其中initiating信令报文是一种用于发起某种操作的消息类型。每个字节对应的含义如下：

第1个字节：
- Bit 8：消息类型（固定为0x00）
- Bit 7-5：版本号（固定为0x00）
- Bit 4-1：保留（固定为0x00）

第2个字节：
- Bit 8-6：消息类别（固定为0x00）
- Bit 5-1：保留（固定为0x00）

第3个字节：
- Bit 8-1：消息长度（不包括消息头部分），取值范围为0-253

第4-5个字节：
- Bit 16-1：消息序号，用于标识消息的唯一性

第6-7个字节：
- Bit 16-1：保留，固定为0x0000

第8个字节：
- Bit 8-1：操作类型，用于指定要发起的操作

后续字节：
- 根据操作类型不同，后续字节的含义也不同。具体解析需要参考相关协议规范。

这是Nmap工具的扫描结果输出，它表示对IP地址为192.168.0.192的主机进行了端口扫描、服务扫描和操作系统探测等操作。具体扫描过程如下：

1.加载了146个用于扫描的脚本。

2.进行了ARP Ping扫描，发现了1个主机。

3.进行了并行DNS解析，解析成功1个主机。

4.进行了SYN Stealth扫描，扫描了1000个端口，扫描时间为3.16秒。

5.进行了服务扫描和操作系统探测，但由于指纹匹配过多，无法给出具体的操作系统信息。

6.最终扫描结果显示，该主机所有的1000个端口都是关闭的。

总的来说，这是一次基本的主机扫描，主要针对了IP地址为192.168.0.192的主机，但没有发现开放的端口和具体的操作系统信息。需要根据具体情况和需求，进行更深入的扫描和分析。

这是一个 Nmap 端口扫描的结果报告。报告显示扫描了 IP 地址为 122.227.161.206 的主机，扫描时间为 17.90 秒。然而，结果报告显示该主机处于宕机状态，无法访问。报告中的“[host down]”表示该主机已经下线或者无法响应。建议可以尝试使用 -Pn 参数来跳过 ping 测试，这样可能会有更好的扫描结果。
