解决 OSX 上原生 VPN (Cisco IPSec)每隔一小时要求输入密码的情况
View gist:3481797

解决方案来自:[Apple Support Communities] (

  1. 连接 VPN Cisco IPSec (让系统生成配置文件)
  2. 拷贝配置文件到/etc/racoon打开终端执行:
    $ sudo cp /var/run/racoon/ /etc/racoon
  3. 修改 racoon 配置文件:
    $ sudo vim /etc/racoon/racoon.conf
  4. 将最后一行注释掉(目的是不使用系统生成配置):
    # include "/var/run/racoon/*.conf" ;
  5. 将下面一行添加到文件末尾,包含分号(使用定制的配置文件):
