openvpn包里缺了个/etc/openvpn/update-resolv-conf

编译和打包
1

启动vpn时需要这个文件。其他发行版里有

2

没用过，我猜需要自己创建，或者这个文件在其他地方提供了。

3

我用过这么多次openvpn，没见过这个啊？不过我不设置dns。这个应该是个脚本，要自己写的，和密码认证脚本一样。

有些地方给的ovpn文件里就有（难道是针对deb系的？）

up /etc/openvpn/update-resolv-conf
down /etc/openvpn/update-resolv-conf

从debian包里取的update-resolv-conf：

#!/bin/bash
# 
# Parses DHCP options from openvpn to update resolv.conf
# To use set as 'up' and 'down' script in your openvpn *.conf:
# up /etc/openvpn/update-resolv-conf
# down /etc/openvpn/update-resolv-conf
#
# Used snippets of resolvconf script by Thomas Hood and Chris Hanson.
# Licensed under the GNU GPL.  See /usr/share/common-licenses/GPL. 
# 
# Example envs set from openvpn:
#
#     foreign_option_1='dhcp-option DNS 193.43.27.132'
#     foreign_option_2='dhcp-option DNS 193.43.27.133'
#     foreign_option_3='dhcp-option DOMAIN be.bnc.ch'
#

我第一次用openvpn

看错文件名，确实是deb有。
