tcpdump捕获了大量的镜像包，但是访问日志内数据却很少

Open zorogong opened this issue 7 years ago • 4 comments

目前的部署方式，在线服务器（10.10.159.99），测试服务器和辅助服务器（10.10.136.11）放在一台上，测试服务器能够抓到大量的包，但是访问日志内请求数据却很少，执行命令如下： ./intercept -i eth0 -F tcp and src port 80 -d ./tcpcopy -x 80-10.10.136.11:80 -s 10.10.136.11 -d

抓获的数据包如下： 16:57:21.207052 IP 10.10.251.35.60291 > 10.10.136.11.80: Flags [S], seq 1697152367, win 28800, options [mss 1440,sackOK,TS val 857761608 ecr 0,nop,wscale 9], length 0 16:57:21.207096 IP

响应包需要被干掉的，要是回到了真正的客户端，会立即回送reset数据包的，这就是问题的所在。 路由设置是黑洞掉响应包的方式之一

当然如果在云平台，你也可以在tcpcopy设置-c参数成tcpcopy所在机器的ip地址，然后在tcpcopy所在的机器设置iptables来黑洞掉测试服务器回来的响应包

目前是在ucloud云平台，我能否直接在测试服务器上直接DROP掉响应包呢 iptables -A OUTPUT -o eth0 -p tcp --sport 80 -j DROP 或者我在在线服务器上将-c参数设置成一台机器的IP10.10.136.12，然后再12上面drop掉响应的包呢，在线服务器我这边没有操作权限，业务也不太愿意直接增加一条iptables iptables -I INPUT -p tcp -s10.10.136.11 --sport 80 -j DROP

额外请教下： 辅助服务器程序不会主动将包给丢弃掉吗？ 需要使用iptables来丢弃？

如果要在测试服务器iptables drop掉，请参考：https://github.com/session-replay-tools/tcpcopy/issues/279

tcpcopy和intercept所在的机器都没有iptables和route的权限，在这种情况下该如何解决reset包的问题。有没有其他办法来丢弃响应包。
