tcpdump用法
-i eth0 表示网卡 -A 表示转为ascii码 -n 表示不要转域名,用ip就好 host 后面加IP地址
查看nginx是长连接还是短连接:
[root@nginx01 ~]# tcpdump -i eth0 -A host 192.168.156.44 -n | grep HTTP tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 262144 bytes .oJ&...ePOST /v2/story/comic/xxx/top HTTP/1.1 ...}.oJ&HTTP/1.1 200 OK .oN.....POST /v1/story/xxx HTTP/1.1 .....oN.HTTP/1.1 200 OK .oN....:POST /v1/story/xxx HTTP/1.1 ...[.oN.HTTP/1.1 200 OK .oR....BPOST /v2/story/comic/xxx/top HTTP/1.1 .oS....MPOST /v1/story/xxx HTTP/1.1 ...`.oR.HTTP/1.1 200 OK
结果:
HTTP/1.1 实锤
