北京联通EdgeRouter开启IPv6

看到说北京联通的pppoe也开始启用ipv6了,在EdgeRouter Lite上开了一下设置。

联通给了个 /56 的prefix。

我的eth1接了上行,pppoe拨号,eth0是lan。

lan

记住配置防火墙

lldb 断点自动执行命令

调试某软件,需要取到断点时候的内存数据。

之前是每次到断点,一个地址一个地址地 p 或者 memory read,后来看到 breakpoint command 命令,于是有了:

添加断点

添加命令

输入命令

这样,每次运行到断点的时候,就会执行这两条命令。

Run HelloWorld on Jailbroken iOS 11

iPhone 5s, iOS 11.1

Jailbroken by Electra

How to jailbreak

Cydia Impactor and a new Apple ID required (You can use your own Apple ID at your risk).

If any error occurs on Cydia Impactor, try to login in Xcode and remove useless app/cert.

Trust your developer certificate in iOS Settings => General => Profiles & Device Management => DEVELOPER APP.

Write HelloWorld

helloworld.c

build

sign with jtool

ent.xml

upload and run helloworld

If this binary is not signed with platform-application entitlement, it will get a ‘Killed’ if it’s under /bin/

More

I wrote a cli based memory editor, which requires more than a hello world.

1 entitlements

2 patch_setuid() from coolstar’s example. But I’m using code from electra’s cydia fork, also mentioned after his example.
