tcpdump note
本文主要是介绍tcpdump note，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
参数
tcpdump | grep ip找不到想要的报文
推荐加上-n, 或者-nn
-n 不做域名解析（显示ip）
-nn不做协议，端口解析
tcpdump默认做了反向域名解析，所有grep不到ip
-t参数
●没有-同参数[root@fqguoCentos ~]# tcpdump -i ens192 dropped privs to tcpdump tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on ens192, link-type EN10MB (Ethernet), capture size 262144 bytes 22:22:04.350003 IP fqguoCentos.ssh > 10.201.4.135.51351: Flags [P.], seq 2211629083:2211629323, ack 3337987731, win 306, length 240 22:22:04.350323 IP fqguoCentos.51002 > hangzhou.zjhzptt.net.cn.domain: 32317+ PTR? 135.4.201.10.in-addr.arpa.
