iOS远程虚拟界面不起作用

问题描述

我想捕获iPhone上的净流量.因此，我在官方网站上遵循了Guid.

I want to capture the net traffic on my iPhone. So I followed the guid on the official site.

1. 通过USB将iOS设备连接到Mac.

2. $ rvictl -s UDID

1. Connect iOS device to the Mac via USB.

2. $ rvictl -s UDID

我通过ifconfig -l看到了rvi0接口.我使用tcpdump捕获数据包:$ sudo tcpdump -i rvi0 -ntcpdump:警告:rvi0:该设备不支持混杂模式(BIOCPROMISC:套接字不支持该操作)tcpdump:警告:rvi0:未分配IPv4地址tcpdump:禁止详细输出，请使用-v或-vv进行完整协议解码在rvi0上侦听，链接类型RAW(原始IP)，捕获大小为65535字节

I saw the interface rvi0 via ifconfig -l. I used tcpdump to capture the packet:$ sudo tcpdump -i rvi0 -ntcpdump: WARNING: rvi0: That device doesn't support promiscuous mode(BIOCPROMISC: Operation not supported on socket)tcpdump: WARNING: rvi0: no IPv4 address assignedtcpdump: verbose output suppressed, use -v or -vv for full protocol decodelistening on rvi0, link-type RAW (Raw IP), capture size 65535 bytes

然后，我使用iphone5(ios:7.0.2)浏览了一个正常工作的网页.但是还有tcpdump不会捕获任何pakect.

Then I used my iphone5(ios:7.0.2) browse a web page, which worked as normal. But there isno pakect captured by the tcpdump.

推荐答案

请查看远程虚拟接口文档. rvictl -s <<UDID>>随设备一起运行该工具.输出行应显示类似Starting device <<UDID>> [SUCCEEDED] with interface <<INTERFACE>>的内容.要查看数据包，请输入sudo tcpdump -i <<INTERFACE>> -w trace.pcap完成捕获后，使用rvictl -x <<UDID>>删除RVI并使用数据包分析器工具(即WireShark，可可数据包分析器等)打开trace.pcap(位于当前工作目录中).

Please look at the Remote Virtual Interface docs. rvictl -s <<UDID>> just runs the tool with your device. An output line should read something like Starting device <<UDID>> [SUCCEEDED] with interface <<INTERFACE>>To view the packets, enter sudo tcpdump -i <<INTERFACE>> -w trace.pcapWhen finished with your capture, remove the RVI using rvictl -x <<UDID>> and open trace.pcap (located in your current working directory) using a packet analyzer tool (i.e. WireShark, Cocoa Packet Analyzer, etc.).
