出发点：在linux电脑上面绑定多条adsl链路做家庭带宽及个人DC使用：
0、账号文件：adsl.user【账号 密码】
|
1 2 3 4 5 |
adsluser1 adslpasswd1 adsluser2 adslpasswd2 adsluser3 adslpasswd3 adsluser4 adslpasswd4 …… |
管理网卡策略路由：
vi /etc/iproute2/rt_tables
|
1 2 3 |
…… 252manage …… |
下面两条策略放到/etc/rc.local中，并手动执行一遍：
ip route add default via 10.255.255.1 table manage
ip rule add from 10.255.255.0/25 table manage
升级网卡驱动：[注意内核要和内核的头文件版本号完全一致]

sh /root/adsl/0-adsl.sh /root/adsl/adsl.user p5p1
2、拨号启动脚本：1-iprule.sh

sh /root/adsl/1-iprule.sh
3、进程检查脚本：/root/adsl/2-adslcheck.sh【adsl出现down掉之后需要进行重启】

chmod +x /root/adsl/2-adslcheck.sh
echo “*/10 * * * * root /root/adsl/2-adslcheck.sh > /dev/null 2>&1″ > /etc/cron.d/adslcheck
4、adsl定期重启
定期重启脚本：3-restartadsl.sh，防止在晚高峰的时候网络掉线

#!/bin/bash beginnum=0 endnum=`ls /etc/sysconfig/network-scripts/ifcfg-ppp*|wc -l` let endnum=endnum-1 function UPppp() { num=$1 ifup ppp$num sleep 5 rulenum=`ip rule | awk '$NF~"^ppp'$num'$"'|wc -l` while [ "$rulenum" -gt "0" ] ;do ip rule del lookup ppp$num;let rulenum--;done ip route add 0/0 dev ppp$num table ppp$num ip rule add fwmark 0x1$num table ppp$num pref 100 ipaddr=`ifconfig ppp$num|awk '$1~"inet" && $2~"^[0-9]"{print $2}'` if [ "$ipaddr" != "" ] then ip rule add from $ipaddr table ppp$num pref 200 fi iptablenum=`iptables -t mangle -L -n|awk '$1~"MARK" && $NF~"^0x1'$num'$"'|wc -l` while [ "$iptablenum" -gt "0" ] ; do iptables -t mangle -D INPUT -i ppp$num -m state --state NEW -j MARK --set-mark 0x1$num ; let iptablenum--;done iptables -t mangle -A INPUT -i ppp$num -m state --state NEW -j MARK --set-mark 0x1$num } function restartadsl() { begnum=$1 endnum=$2 for num in `seq $beginnum $endnum` do ifdown ppp$num done sleep 5 for num in `seq $beginnum $endnum` do UPppp $num done } restartadsl $beginnum $endnum |
echo “0 6 */3 * * root /root/adsl/3-restartadsl.sh > /dev/null 2>&1″ > /etc/cron.d/adslrestart
5、做随机启动配置：添加网卡脚本addnet.sh
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 |
#!/bin/bash adslfile=$1 dev=$2 num=0 function ShowUsage() { echo -e '\033[32;1mUsage: '$0 'adslfile netdev(like p5p1) \033[0m' echo exit 1 } function addnet() { adslfile=$1 cat $adslfile|while read adsluser adslpasswd vlanid other do ip link add link $dev dev adsl$num type macvlan mode private let num++ done } if [ $# -ne 2 ] then ShowUsage else if [ -f $adslfile ];then addnet $adslfile fi fi |
在/etc/rc.local里面添加如下内容：
|
1 2 3 4 5 6 |
…… ip route add default via 10.255.255.1 table manage ip rule add from 10.255.255.0/25 table manage /root/adsl/addnet.sh /root/adsl/adsl.user p5p1 /root/adsl/1-iprule.sh …… |
