可以增加 65500 字节的最大 ping 大小吗？

Question

我可以覆盖默认的最大大小 - 65535 bytesICMP ping 数据包吗？如果 - 那么如何？

Answer 1

IPv4 数据包的最大大小为 65535 字节，其中一些是协议开销，因此数据必须比 65535 少几个字节，并且 ping 不能超过一个 IP 数据包，因此答案是否定的。

为什么要发送更大的 ping？

Answer 2

是的

在 Windows 中，输入：

Ping <target> -l xx

其中 xx 是缓冲区大小。

有关 Windows ping 命令的完整选项 -

Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-i TTL] [-v TOS]
        [-r count] [-s count] [[-j host-list] | [-k host-list]]
        [-w timeout] [-R] [-S srcaddr] [-4] [-6] target_name

Options:
-t             Ping the specified host until stopped.
               To see statistics and continue - type Control-Break;
               To stop - type Control-C.
-a             Resolve addresses to hostnames.
-n count       Number of echo requests to send.
-l size        Send buffer size.
-f             Set Don't Fragment flag in packet (IPv4-only).
-i TTL         Time To Live.
-v TOS         Type Of Service (IPv4-only. This setting has been deprecated
               and has no effect on the type of service field in the IP Header).
-r count       Record route for count hops (IPv4-only).
-s count       Timestamp for count hops (IPv4-only).
-j host-list   Loose source route along host-list (IPv4-only).
-k host-list   Strict source route along host-list (IPv4-only).
-w timeout     Timeout in milliseconds to wait for each reply.
-R             Use routing header to test reverse route also (IPv6-only).
-S srcaddr     Source address to use.
-4             Force using IPv4.
-6             Force using IPv6.
