网络抓包 tcpdump 使用指南 在网络问题的调试中，tcpdump应该说是一个必不可少的工具，和大部分linux下优秀工具一样，它的特点就是简单而强大。它是基于Unix系统的命令行式的数据包嗅探工具，可以抓取流动在网卡上的数据包。监听所有网卡所有包tcpdump监听指定网卡的包tcpdump -i ens18监听指定IP的包tcpdump host 192.168.1.11监听指定来源IPtcpdump src host 192.168.1.11监听目标地址IPtcpdump dst host 192.168.1.11监听指定端口tcpdump port 80监听TCPtcpdump tcp监听UDPtcpdump udp监听192.168.1.11的tcp协议的80端口的数据包tcpdump tcp port 80 and src host 192.168.1.11 11:59:07.836563 IP 192.168.1.11.39680 > hello.http: Flags [.], ack 867022485, win 502, length 0 11:59:07.836711 IP 192.168.1.11.39680 > hello.http: Flags [P.], seq 0:77, ack 1, win 502, length 77: HTTP: HEAD / HTTP/1.1 11:59:07.838462 IP 192.168.1.11.39680 > hello.http: Flags [.], ack 248, win 501, length 0 11:59:07.838848 IP 192.168.1.11.39680 > hello.http: Flags [F.], seq 77, ack 248, win 501, length 0 11:59:07.839192 IP 192.168.1.11.39680 > hello.http: Flags [.], ack 249, win 501, length 0监听IP之间的包tcpdump ip host 192.168.1.11 and 192.168.1.60 11:57:52.742468 IP 192.168.1.11.38978 > hello.http: Flags [S], seq 3437424457, win 64240, options [mss 1460,sackOK,TS val 2166810854 ecr 0,nop,wscale 7], length 0 11:57:52.742606 IP hello.http > 192.168.1.11.38978: Flags [S.], seq 3541873211, ack 3437424458, win 64240, options [mss 1460,nop,nop,sackOK,nop,wscale 7], length 0 11:57:52.742841 IP 192.168.1.11.38978 > hello.http: Flags [.], ack 1, win 502, length 0 11:57:52.742927 IP 192.168.1.11.38978 > hello.http: Flags [P.], seq 1:78, ack 1, win 502, length 77: HTTP: HEAD / HTTP/1.1 11:57:52.742943 IP hello.http > 192.168.1.11.38978: Flags [.], ack 78, win 502, length 0 11:57:52.744407 IP hello.http > 192.168.1.11.38978: Flags [P.], seq 1:248, ack 78, win 502, length 247: HTTP: HTTP/1.1 200 OK 11:57:52.744613 IP 192.168.1.11.38978 > hello.http: Flags [.], ack 248, win 501, length 0 11:57:52.744845 IP 192.168.1.11.38978 > hello.http: Flags [F.], seq 78, ack 248, win 501, length 0 11:57:52.745614 IP hello.http > 192.168.1.11.38978: Flags [F.], seq 248, ack 79, win 502, length 0 11:57:52.745772 IP 192.168.1.11.38978 > hello.http: Flags [.], ack 249, win 501, length 0监听除了与192.168.1.4之外的数据包tcpdump ip host 192.168.1.60 and ! 192.168.1.4 11:57:20.862575 IP 192.168.1.9.47190 > hello.9200: Flags [P.], seq 3233461117:3233461356, ack 1301434191, win 9399, length 239 11:57:20.878165 IP hello.9200 > 192.168.1.9.47190: Flags [P.], seq 1:4097, ack 239, win 3081, length 4096 11:57:20.878340 IP hello.9200 > 192.168.1.9.47190: Flags [P.], seq 4097:8193, ack 239, win 3081, length 4096 11:57:20.878417 IP 192.168.1.9.47190 > hello.9200: Flags [.], ack 4097, win 9384, length 0组合示例tcpdump tcp -i ens18 -v -nn -t -A -s 0 -c 50 and dst port ! 22 and src net 192.168.1.0/24 -w ./cby.cap (1)tcp: ip icmp arp rarp 和 tcp、udp、icmp这些选项等都要放到第一个参数的位置，用来过滤数据报的类型 (2)-i eth1 : 只抓经过接口eth1的包 (3)-t : 不显示时间戳 (4)-s 0 : 抓取数据包时默认抓取长度为68字节。加上-S 0 后可以抓到完整的数据包 (5)-c 50 : 只抓取50个数据包 (6)dst port ! 22 : 不抓取目标端口是22的数据包 (7)src net 192.168.1.0/24 : 数据包的源网络地址为192.168.1.0/24 (8)-w ./cby.cap : 保存成cap文件，方便用ethereal(即wireshark)分析 (9)-v 使用 -v，-vv 和 -vvv 来显示更多的详细信息，通常会显示更多与特定协议相关的信息。 (10)-nn 单个 n 表示不解析域名，直接显示 IP；两个 n 表示不解析域名和端口。 (11)-A 表示使用 ASCII 字符串打印报文的全部数据组合过滤器 《与/AND/&&》 《或/OR/||》 《非/not/!》 and or && or or || not or !在HTTP中提取用户头tcpdump -nn -A -s0 -l | grep "User-Agent:" User-Agent: Prometheus/2.30.0 User-Agent: Microsoft-Delivery-Optimization/10.0在HTTP中同时提取用户头和主机信息tcpdump -nn -A -s0 -l | egrep -i 'User-Agent:|Host:' Host: 192.168.1.42:9200 User-Agent: Prometheus/2.30.0 HOST: 239.255.255.250:1900 USER-AGENT: Microsoft Edge/97.0.1072.55 Windows抓取 HTTP GET 流量tcpdump -s 0 -A -vv 'tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x47455420' 11:55:13.704801 IP (tos 0x0, ttl 64, id 14605, offset 0, flags [DF], proto TCP (6), length 291) localhost.35498 > localhost.9200: Flags [P.], cksum 0x849a (incorrect -> 0xd0b0), seq 3090925559:3090925798, ack 809492640, win 630, options [nop,nop,TS val 2076158003 ecr 842090965], length 239 E..#9.@.@.}C... ...+..#..;..0?.....v....... {..321I.GET /metrics HTTP/1.1 Host: 192.168.1.43:9200 User-Agent: Prometheus/2.30.0 Accept: application/openmetrics-text;

为kubernetes（k8s）单独配置kubectl工具 介绍Kubernetes API 是一个 HTTP REST API。这个 API 是真正的 Kubernetes 用户界面，通过它可以完全控制它。这意味着每个 Kubernetes 操作都作为 API 端点公开，并且可以通过对该端点的 HTTP 请求进行。因此，kubectl 的主要目的是向 Kubernetes API 发出 HTTP 请求：配置apt软件源root@hello:~# apt-get update && apt-get install -y apt-transport-https Hit:1 http://192.168.1.104:81/ubuntu focal InRelease Hit:2 http://192.168.1.104:81/ubuntu focal-security InRelease Hit:3 http://192.168.1.104:81/ubuntu focal-updates InRelease Hit:4 http://192.168.1.104:81/ubuntu focal-proposed InRelease Hit:5 https://mirrors.aliyun.com/docker-ce/linux/ubuntu focal InRelease Reading package lists...
