![lsof 中的未知 SSH 连接](https://linux22.com/image/1564344/lsof%20%E4%B8%AD%E7%9A%84%E6%9C%AA%E7%9F%A5%20SSH%20%E8%BF%9E%E6%8E%A5.png)
这个输出是否意味着这个IP已经连接到SSH?
root@ubuntu:/home/stg03# lsof -i
sshd 16782 root 3u IPv4 59791433 0t0 TCP 192.168.3.237:ssh->**58.218.198.156:53245** (ESTABLISHED)
sshd 16783 sshd 3u IPv4 59791433 0t0 TCP 192.168.3.237:ssh->**58.218.198.156:53245** (ESTABLISHED)
因为这个IP每次在监听器里都会改变,而且它不属于我,是中国IP。
sshd 16687 root 3u IPv4 59787130 0t0 TCP 192.168.3.237:ssh->**221.194.47.205**:39660 (ESTABLISHED)
sshd 16688 sshd 3u IPv4 59787130 0t0 TCP 192.168.3.237:ssh->**221.194.47.205**:39660 (ESTABLISHED)
