先去 https://telerik-fiddler.s3.amazonaws.com/fiddler/fiddler-mac.zip 下载这个mac版，解压
去对应地址下载mono，安装
执行 /Library/Frameworks/Mono.framework/Versions/Current/bin/mozroots --import --sync
去解压的那个路径执行 mono --arch=32 Fiddler.exe 这样就跑起来了

从我windows7的机器打包了vagrant镜像到新的windows10的机器，结果vagrant的private_network设置没效了对比了旧机器的设置之后，发现是eth1不见了，在旧机器上eth1的ip就是本地设的192.168.33.11，但是新机器上没有eth1，多了一个eth2，没有对应的ip

因为guest机装的是centos6，我在service network restart之后报了个错是弹出界面 eth1：设备 eth1 似乎不存在, 初始化操作将被延迟。

于是我检查了/etc/udev/rules.d/70-persistent-net.rules，这台虚拟机镜像里前辈已经留下了一个/etc/udev/rules.d/70-persistent-net.rules.bak

我rm /etc/udev/rules.d/70-persistent-net.rules（在此之前已经备份了）然后reboot

	Basic vs Extended Regular Expressions
	In basic regular expressions the meta-characters ?, +, {, \|, (, and ) lose their special meaning; instead use the backslashed versions \?, \+, \{, \\|, \(, and \).

	Traditional egrep did not support the { meta-character, and some egrep implementations support \{ instead, so portable scripts should avoid { in grep -E patterns and should use [{] to match a
	literal {.

	GNU grep -E attempts to support traditional usage by assuming that { is not special if it would be the start of an invalid interval specification. For example, the command grep -E '{1' searches for
	the two-character string {1 instead of reporting a syntax error in the regular expression. POSIX.2 allows this behavior as an extension, but portable scripts should avoid it.

	Citing Ron Maupin's answer from https://networkengineering.stackexchange.com/questions/33397/debugging-no-route-to-host-over-ethernet:

	The ICMP message, "no route to host," means that ARP cannot find the layer-2 address for the destination host. Usually, this means that that the host with that IP address is not online or responding.

	`rustc -C debuginfo=2 t/src/main.rs`
	that is, using `-C debuginfo=2`
