Fedora下连接浙大vpn
Monday, June 21, 2010
首先要装好xl2tpd
yum install xl2tpd
然后修改/etc/xl2tpd/xl2tpd.conf
vi /etc/xl2tpd/xl2tpd.conf
[global] ; Global parameters:
port = 1701 ; * Bind to port 1701
[lac zju] ; Example VPN LAC definition
lns = lns.zju.edu.cn ; * Who is our LNS?
refuse pap = yes ; * Refuse PAP authentication
require authentication = no ; * Require peer to authenticate
name = 20910027@a ; * Report this as our hostname
ppp debug = yes ; * Turn on PPP debugging
pppoptfile = /etc/xl2tpd/zju.options ; * ppp options file for this lac
创建/etc/xl2tpd/zju.options
vi /etc/xl2tpd/zju.options
asyncmap 0
noauth
crtscts
lock
hide-password
modem
netmask 255.255.255.0
proxyarp
lcp-echo-interval 30
lcp-echo-failure 4
ipcp-accept-local
ipcp-accept-remote
noipx
修改/etc/ppp/chap-secrets
vi /etc/ppp/chap-secrets
username * "password" *
然后创建连接脚本
vi vpn.sh
