IOS dump out As:

dd if=c_ios.image.bin bs=16 skip=7 of=c_dump_out.bz2

bzip2 -d c_dump_out.bz2

ingore any warnning message.

you'll get a raw file .

After about 20 days hard work, it's been tested today.
the peak speed at 225k bytes/s  :)
but TCO not cheap......  Beside all ,it's worked for me..
paste shell script here:

---------- Compile kernel first -----------------

#with below options

[*] Socket Filtering <*> Unix domain sockets [*] TCP/IP networking [*] IP: multicasting [*] IP: advanced router [*] IP: policy routing [*] IP: use netfilter MARK value as routing key [*] IP: fast network address translation [*] IP: equal cost multipath [*] IP: use TOS value as routing key [*] IP: verbose route monitoring [*] IP: large routing tables

--------------------- Shell script BEGIN --------------------

echo 1 > /proc/sys/net/ipv4/ip_forward

dhclient eth0 dhclient eth1 # get ip address from ISP's CM-DHCPD

ifconfig eth2 netmask

ext_ip0=`ifconfig eth0 | grep inet | cut -f 2 -d : | cut -f 1 -d \ ` ext_ip1=`ifconfig eth1 | grep inet | cut -f 2 -d : | cut -f 1 -d \ `

insmod /lib/modules/2.4.20-xfs/kernel/net/sched/sch_teql.o

iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source $ext_ip0 iptables -t nat -A POSTROUTING -o eth1 -j SNAT --to-source $ext_ip1

dhcpd eth2 # set default route in dhcpd.conf as

gw0=`ip route list | grep eth0 | grep default | cut -f 3 -d \ ` gw1=`ip route list | grep eth1 | grep default | cut -f 3 -d \ `

route delete default gw $gw0 route delete default gw $gw1

ip route replace default nexthop via $gw0 dev eth0 weight 1 nexthop via $gw1 dev eth1 weight 1

ip route flush cache

This spring festival, I spend all the holiday on DOC & Linux-ip-chunk project.

------------- | eth0 | <-----> cable modem Private Network <--> | eth2 | (get ip from isp) ( | .0.1 eth1 | <-----> cable modem ------------- (get ip from isp) Linux router

It's seemed a complex & puzzleheaded project.
I want to made Private Network bound transfer speed with all that egress connection

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.

If you're a C programmer with some spare time, take a look at the mod_virgule project page and help us with one of the tasks on the ToDo list!
