LARTC - Aug 2007 - again the same prob that is ::two providers (heres full description )

many many thanks for ur help
  ok i m making my problem more clear...
  
  my LAN ip is :172.16.100.0/24
  ip of eth1 is :202.51.78.122  and this is fixed and permanent address
                 and it has no netmask and gateway(so, to provide internet to my
LAN i have used the ppp0 for this connection )
  ip of eth2 : 203.78.165.154; netmask:255.255.255.248; gateway:203.78.165.153
  
 for eth0 my file is :/etc/sysconfig/network-scripts/ifcfg-eth0
  for eth1 :/etc/sysconfig/network-scripts/ifcfg-eth1
  for eth2:/etc/sysconfig/network-scripts/ifcfg-eth2
  
  and my rules are placed in /etc/iproute2/rt_tables as suggested by lartc.org
   
  and the whole copy of my above file is copied below:::>>>
  
  
  #
  # reserved values
  #
  #255    local
  #254    main
  #253    default
  #0      unspec
  #
  # local
  #
  #1      inr.ruhep
  
  #
  # below this is added by me and above this is by default
  # two addational routing tables
  
  #ip route add 202.51.78.0/24 dev eth1 src ppp0 table T1
  #ip route add default via ppp0 table T1
  ip route add 203.78.165.0/24 dev eth2 src 203.78.165.154 table T2
  ip route add default via 203.78.165.153 table T2
  
  # main routing table
  
 ip route add 202.51.78.0/24 dev eth1 src ppp0
 ip route add 203.78.165.0/24 dev src 203.78.165.154
 
 # preference for default route
 
 ip route add default via 202.51.76.122
 
 # routing rules
 
 ip rule add from ppp0 table T1
 ip rule add from 203.78.165.154 table T2
 
 # entries for local network
 
 ip route add 172.16.100.0/24    dev eth0 table T1
 ip route add 203.78.165.0/24    dev eth2 table T1
 ip route add 127.0.0.0/8        dev lo   table T1
 ip route add 172.16.100.0/24    dev eth0 table T2
 ip route add 202.51.78.0/24     dev eth1 table T2
 ip route add 127.0.0.0/8        dev lo   table T2
 
 #load balancing
 ip route add default scope global nexthop via ppp0 dev eth1 weight 1 nexthop
via 203.78.165.153 dev eth2 weight 1
 
 this above one is the full and exact copy of my working....

 i think this is not a new problem for this forum....but its newest for me as i
m a new  linux lerner. Even if it is new plzz....reply me ur answer..n if its
already asked n have solution..plzz forward the solution.  My problem is here
mentioned:
 I have fedora core 4 as a linux server. there r two external links connected to
this.
I there are 2 external links, What is the file /etc/sysconfig/network  like?

Can you witre down the file? 



 the settings are as: eth0 ->for internal (that is for LAN) 
                              eth2 ->dsl connection
                              eth1 ->cable line connection( this connection
has no gateway and netmask address provided so this is connected via ppp0. this
is provided from ISP via DHCP but have the fixed ipaddress) Hey, What is this
FIXED ip address? Is it a perment address?

 
YOUR eth0 of Fedora Server is for internal (that is for LAN)
YOUR eth2 of Fedora Server is connected to the dsl connection. 
YOUR eth1 of Fedora Server is connected to the cable line connection. It has a
ip.


 i want to use these two link to provide the internet in my LAN where there are
about 8 to 10 computers. i want that if any of the link goes down ...the other
should  continue the internet ...n also while both the links r up..the load
should be shared   between these two links....so that the net conection and
downloads be faster....
 
 i have heard about the scripts....that can do this....but i have no idea how to
write these...scripts. i need these  to be on after reboot also...
To come up the script after the reboot, There are two ways. Either you have to
write everytning IN /etc/rc.d/rc.local or write the script as a seperate file
and and make it executable by using chmod.

Pls see bellow. 

first create the file as follows. 

touch /etc/rc.d/loadbalancing

then , By using vi editor write the script and save it as usual. Then , Make it
executable as follows.

chmod 755 /etc/rc.d/loadbalancing

and finally add PATH OF THE SCRIPT to /etc/rc.d/rc.local file as follows.  

etc/rc.d/loadbalancing

 That''s it. Now, whenever you reboot the system, the scripts also comes
up with the system.
 



 i tried my best and i also refered the  lartc.org ..but i could do a little
only.
 
 WHAT I DID: it works very well if i connect both of the links and the default
path is  via ppp0. but suppose if that is(ppp0) disconnected then the dsl
connection can handle only upto 15/16 seconds. after that it  disconnects .
whats the solution ...plzz...as..soon as..possible...help..me...i m in big
trouble....
 UR SMALL HELP WILL BE A BIG BOON FOR ME

COULD YOU PLS write down your RULES . then, I will be able to help you. 



  Remember that i don''t have gateway and netmask of eth1 connection. 
it has  ip address only.it is NATed via ppp0. and also my all working are based
on  lartc.org only...in case of dsl connection i have just replaced the ip and
gateways with my ip and gateways....n in case of ppp0 conection i have put ppp0
in the place of  gateway n netmask  and in place of ip i have given the ip of
that link.
The above paragraph is not so clear.
