To change a field name in django 1.7+

1.  Edit the field name in the model (but remember the old field name: you need it for step 3!)
2.  Create an empty migration
$ python manage.py makemigrations --empty myApp
3.  Edit the empty migration (it's in the migrations folder in your app folder, and will be the most recent migration) by adding

migrations.RenameField('MyModel', 'old_field_name', 'new_field_name'),

to the operations list.

简介

最近因为电信白名单，国外的服务器只能ping通，高端口基本无法使用，一种解决办法是将翻墙服务启动在80，443等可访问端口，另一种就是本文方法，将数据包封装在ping包中。

使用 hans 这个项目结合 shadowsocks-libev 翻墙。

1. 确认服务器支持IPV6

# ping6 ipv6.google.com
