FreeBSD ADSL 安装 Howto

简单几步,让你用ADSL上网

FreeBSD ADSL 安装Go!Go!Go!

1.配置网络连接

配置ppp.conf

先登录系统，这样：

Login: root  (以Root用户登录)
Password: (输入你的密码，因安全问题，这里你看不到输入的结果.)

由于是ADSL上网，配置文件是 /etc/ppp下的 ppp.conf，在 /etc/ppp 下可能已经有了 ppp.conf 也可能只有 ppp.conf.sample ,总之,我放弃使用现有的ppp.conf 从ppp.conf.sample新建一个.你可以这样做:

# rm ppp.conf  (删除ppp.conf , 如果有的话)
# cp ppp.conf.sample ppp.conf
# ee ppp.conf  (随自己喜好,使用 ee 或 vi )

这里把我的ppp.conf 附上,以此为范本.

default:
 set log Phase Chat LCP IPCP CCP tun command
 ident user-ppp VERSION (built COMPILATIONDATE)
 # Ensure that "device" references the correct serial port
 # for your modem. (cuaa0 = COM1, cuaa1 = COM2)
 #
 set device PPPoE:lnc0
 set speed sync
 set mru 1492
 set mtu 1492
 set ctsrts off
 set timeout 30                 # 3 minute idle timer (the default)
 disable lqr
 deny lqr
 add default HISADDR
 enable dns     # request DNS info (for resolv.conf)
hz163:   # 注意:这里的hz163是你的ISP名,要比下面的set语句多出一点(一个空格).
 set authname user(把这里的user换成你的ADSL用户名)
 set authkey password (把这里的password换成你的ADSL密码) 
 set dial
 set login
 set ifaddr 10.0.0.1/0 10.0.0.2/0
 nat enable yes

连接网络

配置好了ppp.conf，你就成功了一半，接下来的就是输入命令、连接网络喽！

#ppp –ddial hz163

之后看看连接状态。

#ifconfig

我的结果：

lnc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.0.254 netmask 0xffffff00 broadcast 192.168.0.255
inet6 fe80::20c:29ff:fe98:25a6%lnc0 prefixlen 64 scopeid 0x1 ether 00:0c:29:98:25:a6
lp0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
        inet6 ::1 prefixlen 128 
        inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3 
        inet 127.0.0.1 netmask 0xff000000 
ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552
faith0: flags=8002<BROADCAST,MULTICAST> mtu 1500
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1492
inet 218.72.106.94 --> 61.174.64.21 netmask 0xffffffff 
         Opened by PID 54

数字部分就是：ISP分的IP地址 -> ISP的DNS服务器的IP. 这样你就上了网啦！

配置rc.conf使ADSL开机上网

想一开机就上网？简单！让我们来配置 /etc/rc.conf吧，这很简单！就填上这几句：

ifconfig_lnc0="192.168.0.254/24"
defaultrouter="192.168.0.254"
inetd_enable="yes"
gateway_enable="yes"
ppp_enable="yes"
ppp_mode="ddial"
ppp_nat="yes"
ppp_profile="hz163"
named_enable="yes"

这几句就把FreeBSD虚拟机配置成了一NAT网关，兼软路由、BIND8名字服务器。
