Open×××:server.conf与client.conf配置解析
# vi open***-2.3.2/sample/sample-config-files/server.conf
#################################################
# Sample Open××× 2.0 config file for #
# multi-client server. #
# This file is for the server side #
# of a many-clients <-> one-server #
# Open××× configuration. #
# Open××× also supports #
# single-machine <-> single-machine #
# configurations (See the Examples page #
# on the web site for more info). #
# This config should work on Windows #
# or Linux/BSD systems. Remember on #
# Windows to quote pathnames and use #
# double backslashes, e.g.: #
# “C:\\Program Files\\Open×××\\config\\foo.key” #
# Comments are preceded with ‘#’ or ‘;’ #
#################################################
# Which local IP address should Open×××
# listen on? (optional)
# 设置服务器open×××监听IP
;local a.b.c.d
local 192.168.1.180
# Which TCP/UDP port should Open××× listen on?
# If you want to run multiple Open××× instances
# on the same machine, use a different port
# number for each one. You will need to
# open up this port on your firewall.
# open***监听端口,默认1194可自定义,另外防火墙需开放此端口
port 1194
# TCP or UDP server?
# 选择采用何种协议传输
proto tcp
;proto udp
# “dev tun” will create a routed IP tunnel,
# “dev tap” will create an ethernet tunnel.
# Use “dev tap0″ if you are ethernet bridging
# and have precreated a tap0 virtual interface
# and bridged it with your ethernet interface.
# If you want to control access policies
# over the ×××, you must create firewall
# rules for the the TUN/TAP interface.
# On non-Windows systems, you can give
# an explicit unit number, such as tun0.
# On Windows, use “dev-node” for this.
# On most systems, the ××× will not function
# unless you partially or fully disable
# the firewall for the TUN/TAP interface.
# TAP 等同于一个以太网设备,它操作第二层数据包如以太网数据帧。TUN模拟了网络层设备,操作第三层数据包比如IP数据封包。
;dev tap
dev tun
#tap
# Windows needs the TAP-Win32 adapter name
# from the Network Connections panel if you
# have more than one. On XP SP2 or higher,
# you may need to selectively disable the
# Windows firewall for the TAP adapter.
# Non-Windows systems usually don’t need this.
;dev-node MyTap
# SSL/TLS root certificate (ca), certificate
# (cert), and private key (key). Each client
# and the server must have their own cert and
# key file. The server and all clients will
# use the same ca file.
# See the “easy-rsa” directory for a series
# of scripts for generating RSA certificates
# and private keys. Remember to use
# a unique Common Name for the server
# and each of the client certificates.
# Any X509 key management system can be used.
# Open××× can also use a PKCS #12 formatted key file
# (see “pkcs12″ directive in man page).
#Open×××使用的ROOT CA,用build-ca生成,用于验证客户是证书是否合法
#Server使用的证书文件
#Server使用的证书对应的key,官方建议加密此文件以便外泄

# Diffie hellman parameters.
# Generate your own with:
# openssl dhparam -out dh1024.pem 1024
# Substitute 2048 for 1024 if you are using
# 2048 bit keys.
# 4.2中生成的Diffie-Hellman文件,默认2048bit

# Configure server mode and supply a ××× subnet
# for Open××× to draw client addresses from.
# The server will take 10.100.0.1 for itself,
# the rest will be made available to clients.
# Each client will be able to reach the server
# on 10.100.0.1. Comment this line out if you are
# ethernet bridging. See the man page for more info.
# 设置×××网络地址段,设置后服务器IP自动设置为10.1.10.1,客户端IP为10.100.0.2-254
server 10.1.10.0 255.255.255.0
# Maintain a record of client <-> virtual IP address
# associations in this file. If Open××× goes down or
# is restarted, reconnecting clients can be assigned
# the same virtual IP address from the pool that was
# previously assigned.
# 记录服务器分配的虚拟IP记录,中断恢复可重新获取原始IP。
ifconfig-pool-persist ipp.txt
# Configure server mode for ethernet bridging.
# You must first use your OS’s bridging capability
# to bridge the TAP interface with the ethernet
# NIC interface. Then you must manually set the
# IP/netmask on the bridge interface, here we
# assume 10.8.0.4/255.255.255.0. Finally we
# must set aside an IP range in this subnet
# (start=10.8.0.50 end=10.8.0.100) to allocate
# to connecting clients. Leave this line commented
# out unless you are ethernet bridging.
# Bridge状态下类似DHCPD的配置,为客户分配地址,由于这里工作在路由模式,所以不使用
;server-bridge 10.8.0.4 255.255.255.0 10.8.0.50 10.8.0.100
# Configure server mode for ethernet bridging
# using a DHCP-proxy, where clients talk
# to the Open××× server-side DHCP server
# to receive their IP address allocation
# and DNS server addresses. You must first use
# your OS’s bridging capability to bridge the TAP
# interface with the ethernet NIC interface.
# Note: this mode only works on clients (such as
# Windows), where the client-side TAP adapter is
# bound to a DHCP client.
;server-bridge
# Push routes to the client to allow it
# to reach other private subnets behind
# the server. Remember that these
# private subnets will also need
# to know to route the Open××× client
# address pool (10.100.0.0/255.255.255.0)
# back to the Open××× server.
# 推送路由到客户端,允许客户端访问服务器下的子网,此网段是服务器下网段。
push “route 10.100.0.0 255.255.0.0″
# To assign specific IP addresses to specific
# clients or if a connecting client has a private
# subnet behind it that should also have ××× access,
# use the subdirectory “ccd” for client-specific
# configuration files (see man page for more info).
# EXAMPLE: Suppose the client
# having the certificate common name “Thelonious”
# also has a small subnet behind his connecting
# machine, such as 192.168.40.128/255.255.255.248.
# First, uncomment out these lines:
# 为服务器添加到客户端子网的路由,此网段是客户端下的网站
route 10.200.0.0 255.255.0.0
# client-config-dir 为客户端指定IP
;client-config-dir /etc/open***/conf/ccd
# Then add this line to ccd/client:
;iroute 10.200.0.0 255.255.0.0 #此为客户端下子网段
;ifconfig-push 10.1.10.3 10.9.0.4 #此为设定客户端IP
# Suppose that you want to enable different
# firewall access policies for different groups
# of clients. There are two methods:
# (1) Run multiple Open××× daemons, one for each
# group, and firewall the TUN/TAP interface
# for each group/daemon appropriately.
# (2) (Advanced) Create a script to dynamically
# modify the firewall in response to access
# from different clients. See man
# page for more info on learn-address script.
;learn-address ./script
# If enabled, this directive will configure
# all clients to redirect their default
# network gateway through the ×××, causing
# all IP traffic such as web browsing and
# and DNS lookups to go through the ×××
# (The Open××× server machine may need to NAT
# or bridge the TUN/TAP interface to the internet
# in order for this to work properly).
# 使Client的默认网关指向×××,让Client的所有Traffic都通过×××走
;push “redirect-gateway def1 bypass-dhcp”
# Certain Windows-specific network settings
# can be pushed to clients, such as DNS
# or WINS server addresses. CAVEAT:
# http://open***.net/faq.html#dhcpcaveats
# The addresses below refer to the public
# DNS servers provided by opendns.com.
# 为客户端推送DNS
push “dhcp-option DNS 8.8.8.8″
push “dhcp-option DNS 8.8.4.4″
# Uncomment this directive to allow different
# clients to be able to “see” each other.
# By default, clients will only see the server.
# To force clients to only see the server, you
# will also need to appropriately firewall the
# server’s TUN/TAP interface.
# 取消该注释允许不同的客户端可以发现彼此
client-to-client
# Uncomment this directive if multiple clients
# might connect with the same certificate/key
# files or common names. This is recommended
# only for testing purposes. For production use,
# each client should have its own certificate/key
