如果有人以某种方式访问了我的 FTP 服务器上的某个用户,我仍然可以看到他们的 IP 地址并追踪到他们。但是,我担心他们在登录时可能会欺骗他们的 IP 地址。这可能吗,他们会怎么做?

所以我有这个树莓派,当我想使用它时,它可以使用 SSH 登录。
我想知道 Raspberry Pi 的 CPU 是在运行 SSH 命令还是只是将数据发送到我的笔记本电脑以便它可以在我笔记本电脑的 CPU 上运行?

所以,我正在 ping 我的笔记本电脑(从我的笔记本电脑),期望报告中的 TLL 为 128(因为我在 Windows 10 上),但我得到了这个:
Pinging [REDACTED] with 32 bytes of data:
Reply from [REDACTED]: bytes=32 time=3ms TTL=64
Reply from [REDACTED]: bytes=32 time=2ms TTL=64
Reply from [REDACTED]: bytes=32 time=2ms TTL=64
Reply from [REDACTED]: bytes=32 time=2ms TTL=64
Ping statistics for [REDACTED]:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 2ms, Maximum = 3ms, Average = 2ms
128 - 64 = 64 跳
我不明白为什么会这样。
此外,当我使用我的主机名(或链接本地 IPv6 地址)时,我会得到以下信息:

当我使用我的私有 IP 地址时:
