adsl-start /etc/sysconfig/network-scripts/ifcfg-ppp0
adsl-start /etc/sysconfig/network-scripts/ifcfg-ppp1
(adsl-start /etc/sysconfig/network-scripts/ifcfg-pppn)
4.查看新设置是否启动:
方法一:执行: ifconfig
出现ppp0 和ppp1 ,并且均得到ip了.说明成功了,结果象这样:
ppp0 Link encap:Point-to-Point Protocol
inet addr:218.114.37.137 P-t-P:61.142.110.30 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1492 Metric:1
RX packets:165721 errors:0 dropped:0 overruns:0 frame:0
TX packets:123673 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:3
RX bytes:157324193 (150.0 Mb) TX bytes:14068892 (13.4 Mb)
ppp1 Link encap:Point-to-Point Protocol
inet addr:218.114.35.62 P-t-P:61.142.110.30 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1492 Metric:1

方法二: 执行ip高级命令: ip link ls
也可以检验ppp0和ppp1,结果象这样:
1: lo: mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: mtu 1500 qdisc pfifo_fast qlen 100
link/ether 00:50:bf:07:4e:32 brd ff:ff:ff:ff:ff:ff
3: eth1: mtu 1500 qdisc pfifo_fast qlen 100
link/ether 00:01:02:9a:31:b9 brd ff:ff:ff:ff:ff:ff
4: eth2: mtu 1500 qdisc pfifo_fast qlen 100
link/ether 00:e0:4c:79:44:71 brd ff:ff:ff:ff:ff:ff
268: ppp1: mtu 1492 qdisc pfifo_fast qlen 3
link/ppp
273: ppp0: mtu 1492 qdisc cbq qlen 3
link/ppp

方法三: 用命令测试反应
ping -I ppp0 202.96.134.133 (测试ppp0的线路状况)
ping -I ppp1 202.96.134.133 (测试ppp1的线路状况)
ping -I ppp2 ......n (如果还有多条的话)
5.如果单单是要实现链路负载平衡，让ppp0和ppp1分担负载,那么我们象以下设置一下配置:
(1)启动路由,允许转发echo 1 > /proc/sys/net/ipv4/ip_forward
(2)进行伪装:
