我正在尝试在我的 ubuntu 14.04 系统中设置 PPPoE 服务器以进行测试。服务器和客户端都安装了 Ubuntu 14.04。我按照此网站的指南设置了服务器。
http://www.howtodoityourself.org/pppoe-server-how-to-do-it-yourself.html
这是我的接口文件：
# The loopback network interface
auto lo
iface lo inet loopback
# The WAN network interface
auto eth0
# The LAN network interface
auto eth1
iface eth1 inet static
address 192.168.1.254
netmask 255.255.255.0
我的名称服务器：
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1
nameserver 8.8.8.8
nameserver 8.8.4.4
chap秘密文件：
# Secrets for authentication using CHAP
# client server secret IP addresses
"russo" * "1234" 192.168.1.1
PPPoE 服务器选项文件：
# PPP options for the PPPoE server
# LIC: GPL
require-chap
login
lcp-echo-interval 10
lcp-echo-failure 2
ms-dns 8.8.8.8
ms-dns 8.8.4.4
netmask 255.255.255.0
defaultroute
noipdefault
usepeerdns
IP 地址池文件：
192.168.1.1-20
然后，当我通过执行以下命令运行 PPPoE 服务器时：
sudo pppoe-server -C isp -L 192.168.1.254 -p /etc/ppp/allip -I eth1
并设置 NAT
sudo iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o eth0 -j MASQUERADE
然后我使用命令连接我的客户端
sudo pppoeconf
在服务器端，我的 netstat 如下所示：
mr@OptiPlex-760:~$ netstat -pr
Kernel-IP-Routentabelle
Ziel Router Genmask Flags MSS Fenster irtt Iface
default router 0.0.0.0 UG 0 0 0 eth0

192.168.88.0 * 255.255.255.0 U 0 0 0 eth0

muhammadarifurrahman@wm-HP-EliteBook-2540p:~$
我刚刚注意到了这一点：
当我在服务器上启动 PPPoE，然后从客户端连接时，
在服务端我得到：
mr@OptiPlex-760:~$ plog
Jul 10 11:33:05 OptiPlex-760 pppd[3257]: pppd 2.4.5 started by root, uid 0
Jul 10 11:33:05 OptiPlex-760 pppd[3257]: Using interface ppp0
Jul 10 11:33:05 OptiPlex-760 pppd[3257]: Connect: ppp0 <--> /dev/pts/10
在客户端我得到：
muhammadarifurrahman@wm-HP-EliteBook-2540p:~$ plog
Jul 10 11:21:59 wm-HP-EliteBook-2540p pppd[4258]: CHAP authentication succeeded: Access granted

Jul 10 11:21:59 wm-HP-EliteBook-2540p pppd[4258]: peer from calling number 60:E3:27:05:37:78 authorized
然后 2-3 秒后，在服务器端我得到：
mr@OptiPlex-760:~$ plog
Jul 10 11:33:18 OptiPlex-760 pppd[3257]: Peer russo failed CHAP Session verification
Jul 10 11:33:18 OptiPlex-760 pppd[3257]: Connection terminated.
Jul 10 11:33:18 OptiPlex-760 pppd[3257]: Exit.
mr@OptiPlex-760:~$
在客户端：

Jul 10 11:22:09 wm-HP-EliteBook-2540p pppd[4258]: Modem hangup

muhammadarifurrahman@wm-HP-EliteBook-2540p:~$
答案1
好的，我已通过修改 PPoE 服务器选项文件解决了该问题。现在它看起来是这样的：
auth
lcp-echo-failure 3
lcp-echo-interval 60
mtu 1482
mru 1482
require-chap
ms-dns 8.8.8.8
ms-dns 8.8.4.4
netmask 255.255.255.0
defaultroute
noipdefault
usepeerdns
并且一切都运行正常。
答案2
这是您的错误：“7 月 10 日 08:55:06 OptiPlex-760 pppd[4644]: Peer russo 未通过 CHAP 会话验证” - 客户端上的用户/密码设置正确吗？您在服务器名称中输入了什么吗？您应该有一个 *，这样它就可以连接到任何服务器。
