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

#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。

#4

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.

#     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。
