CentOS上实现PPPOE接入

xaliyan

CentOS release 5 (Final) 默认的安装包是ppp-2.4.4 和rp-pppoe-3.5-32.1，配置可以拨号，但是无法通过验证，最终发现是ppp版本兼容性问题，下载ppp-2.4.1-6plf后，强制降级，拨号成功。
配置文件/etc/ppp/options
local
require-pap
login
auth
defaultroute
ipcp-accept-local
ipcp-accept-remote
10.0.0.1:10.0.0.255
netmask 255.255.255.0
ms-dns 192.168.1.144
/etc/ppp/pap-secrets
# client        server secret                  IP addresses
*       *       ""      *
/etc/ppp/pppoe-server-options
logfile /var/log/pppd.log
echo "/sbin/pppoe-server -I eth2.3 -I eth2.101 -I eth2.8" >>/etc/rc.local 启动pppoe-server
附DHCP配置（可用于pppoe动态分配ip）
/etc/dhcpd.conf

option netbios-node-type 8;
option domain-name-servers 192.168.1.144;

ignore client-updates;
