数据包分析
使用 Linux tcpdump 命令来分析网络数据包。使用筛选器来限制数据包收集和输出。您必须登录 Linux shell 才能使用此命令。有关
详细信息，请参阅登录 OS10 设备。
使用不带 tcpdump 参数的 Linux 命令可查看流过所有接口的数据包。要将捕获的数据包写入文件，请使用 -w 参数。要使捕获的文
件输出脱机，您可以使用开放源代码软件包（例如 wireshark）。
从以太网接口捕获数据包
$ tcpdump -i e101-003-0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on e101-003-0, link-type EN10MB (Ethernet), capture size 262144 bytes
01:39:22.457185 IP 3.3.3.1 > 3.3.3.4: ICMP echo request, id 5320, seq 26, length 64
01:39:22.457281 IP 3.3.3.1 > 3.3.3.4: ICMP echo reply, id 5320, seq 26, length 64
从接口捕获两个数据包
$ tcpdump -c 2 -i e101-003-0
listening on e101-003-0, link-type EN10MB (Ethernet), capture size 96 bytes
01:39:22.457185 IP 3.3.3.1 > 3.3.3.4: ICMP echo request, id 5320, seq 26, length 64
01:39:22.457281 IP 3.3.3.1 > 3.3.3.4: ICMP echo reply, id 5320, seq 26, length 64

捕获数据包并写入文件
$ tcpdump -w 06102016.pcap -i e101-003-0
listening on e101-003-0, link-type EN10MB (Ethernet), capture size 96 bytes
