[@ 2000-11-07 7:19 UTC (permalink / raw)]

<PRE>hi---first of all thank u HOW-TO(people here think i'm
genious)--:o))))

but will someone plzz help me !
here is the netork i have

WEb---|server A|--------|server B|---- my clients
     eth0     eth1     eth0     eth1
           10.0.0.3/8   0.2/8    0.1/8

the network is on ip 10.0.0.0/8 with eth0 on server A
as valid ip from ISP ! serverA runs squid &amp; ipchains
while serverB is THE linux router(well want it to
be!).
i have recomplied kernel 2.2.17 with all required
options on redhat6.2 &amp; have the following script!....
but my clients fail to access web---WHY???

#!/sbin/sh
for f in /proc/sys/net/ipv4/conf/*/rp_filter; do
  echo 1 &gt; $f
done
echo 1 &gt; /proc/sys/net/ipv4/ip_forward
echo 1 &gt; /proc/sys/net/ipv4/tcp_syncookies
for f in /proc/sys/net/ipv4/conf/*/accept_redirects;
do
   echo 0 &gt; $f
done
for f in
/proc/sys/net/ipv4/conf/*/accept_source_route; do
   echo 0 &gt; $f
done
######---starting bandwidth

tc qdisc add dev eth0 root handle 10: cbq bandwidth
100Mbit avpkt 1000

tc class add dev eth0 parent 10:0 classid 10:1 cbq

tc filter add dev eth0 parent 10:0 protocol ip prio

tc filter add dev eth0 parent 10:0 protocol ip prio

tc filter add dev eth0 parent 10:0 protocol ip prio
100 u32 match ip src 10.0.255.0/29 flowid 10:200
tc filter add dev eth0 parent 10:0 protocol ip prio
100 u32 match ip src 10.175.0.0/16 flowid 10:200

....etc..etc....same as given in the how-to !!

my mind is now exhausted to find a reason(which i'm
sure is a very basic one)....
one more point to notice is---i want to implement
VirtualServers(load balance) between server A &amp;
B...well dont have much funds really to go in for
those high costing bandwidth at the moment!..

can someone help me plzz with this !
thanking in advance
regards &amp; good luck
