如下图所示，当我netstat -an在命令行中写入时，我得到了图中的答案。最后一行与其他行不同。
有时，我netstat -an在命令行中查询命令。前 4 个字符保持不变，fe80。此行中的其他字符会随时间变化。此外，有时我查询命令时可以看到最后一行，有时看不到netstat -an。最后，这是什么意思？我的电脑上有键盘记录程序吗？这是否意味着有人有时会监视我？
我的命令行输出：
C:\Users\ASUS>netstat -an

答案1
端口 546 是 IPv6 用于 DHCP 的端口。请查看此MS 文章
我不会将这个正在使用的端口与任何可疑活动联系起来。
答案2
尝试
Netstat -anp udp -o
这将显示使用该连接的进程 ID，然后在任务管理器的服务选项卡中查找该 PID。
答案3
不，这绝对不意味着有人在监视你。这意味着 IPv6 正在端口 546 上使用。
让我们找出什么正在使用端口 546。
请执行下列操作：
- 使用提升的权限打开命令提示符
- 运行 Netstat -ano | 找到“546”
- 查找 PID（即进程 ID）
- 打开任务管理器
- 转至流程
- 然后转到视图 > 选择列 > PID
- 现在查找 Netstat 命令中输出的 PID 号码。
这将是使用您看到的 IPv6 地址和端口号的应用程序。这仅表示特定应用程序正在使用此端口。
希望这可以帮助！
