![VPN 到特定组织](https://linux22.com/image/986398/VPN%20%E5%88%B0%E7%89%B9%E5%AE%9A%E7%BB%84%E7%BB%87.png)
我对 ubuntu 15.10 中的 VPN 有疑问。我想连接瑞典隆德大学的 VPN。我有:我的用户名和密码。我还可以从网络管理器配置 VPN,我已经连接到另一个 VPN,但我有三个文件 ca.crt、certificate.crt 和 key.key,它们是通用文件,所以我可以用它们连接到那个 VPN?另外,我不知道网关是什么,可以是 connect.lu.se 吗?
我至少想知道如何使用我在 windows8 上使用的用户名和密码连接到隆德大学。下面您可以找到我所做操作的说明。
右侧部分显示用于创建 VPN 的主网络管理器窗口,左侧 4 个小窗口显示高级选项。为了让免费 VPN 工作,我输入了网关、用户名、密码和下载的三个证书文件,然后转到高级选项。第一个选项卡(常规)我将端口设置为 443,标记使用 LZO 压缩并使用 TCP。第二个选项卡将密码设置为 AES_128-CBC
谢谢,Elsaid

运行这个:
sudo apt-get install openvpn
安装 OpenVPN 包。然后,在您的主目录中创建一个新文件client.conf
。编辑该文件以包含以下内容:
# Specify that we are a client and that we
# will be pulling certain config file directives
# from the server.
client
# Use the same setting as you are using on
# the server.
# On most systems, the VPN will not function
# unless you partially or fully disable
# the firewall for the TUN/TAP interface.
;dev tap
dev tun
# Windows needs the TAP-Win32 adapter name
# from the Network Connections panel
# if you have more than one. On XP SP2,
# you may need to disable the firewall
# for the TAP adapter.
;dev-node MyTap
# Are we connecting to a TCP or
# UDP server? Use the same setting as
# on the server.
;proto tcp

# The hostname/IP and port of the server.
# You can have multiple remote entries
# to load balance between the servers.

# Choose a random host from the remote
# list for load-balancing. Otherwise
# try hosts in the order specified.
;remote-random
# Keep trying indefinitely to resolve the
# host name of the OpenVPN server. Very useful
# on machines which are not permanently connected
# to the internet such as laptops.

# Try to preserve some state across restarts.

# If you are connecting through an
# HTTP proxy to reach the actual OpenVPN

# See the server config file for more

# a separate .crt/.key file pair

key client.key
# Verify server certificate by checking
# that the certicate has the nsCertType
# field set to "server". This is an
# important precaution to protect against
# a potential attack discussed here:

# To use this feature, you will need to generate
# your server certificates with the nsCertType
# field set to "server". The build-key-server
# script in the easy-rsa folder will do this.

# If a tls-auth key is used on the server
# then every client must also have the key.
;tls-auth ta.key 1
# Select a cryptographic cipher.
# If the cipher option is used on the server
# then you must also specify it here.
;cipher x
# Enable compression on the VPN link.
# Don't enable this unless it is also
# enabled in the server config file.

这是 OpenVPN 的通用客户端配置文件。现在,要连接,请从主目录运行以下命令:
sudo openvpn client.conf
使用给定的配置文件进行连接。
确保您的 CA.CRT、CERTIFICATE.CRT 和 KEY.KEY 文件也位于您的主目录中
