CentOS 6.4 PPP配置指南

PPP（点对点协议）是一种在两个节点之间建立连接的协议，常用于拨号上网、VPN连接等场景，CentOS 6.4作为一款流行的Linux发行版，其PPP配置相对简单，本文将详细介绍如何在CentOS 6.4上配置PPP。

安装PPP软件

1. 打开终端。

2. 输入以下命令安装ppp软件包：

   

sudo yum install ppp

安装完成后,输入以下命令启动pppd服务：

sudo systemctl start pppd

为了让pppd服务在系统启动时自动运行,输入以下命令：

sudo systemctl enable pppd

配置PPP连接

1. 创建一个名为/etc/ppp/chap-secrets的文件,用于存储认证信息。

sudo vi /etc/ppp/chap-secrets

在文件中添加以下内容（根据实际情况替换用户名、密码和服务名称）：

username * "password" "yourisp.com"

3. 创建一个名为/etc/ppp/options的文件,用于配置PPP连接选项。

sudo vi /etc/ppp/options

在文件中添加以下内容：

connect /usr/sbin/chat -v -T 192.168.1.1 -A -o -s -w 3 -t 1 'ATDT12345678' 'OK' 'ATDT12345678' 'CONNECT' 'CONNECT OK' 'ATDT12345678' 'CONNECT OK' 'CONNECT' 'CONNECT OK' 'CONNECT' 'CONNECT OK'
