>>That's not good! Either the app handler couldn't properly register
the ip_vs_protocol, or packets flagged with appropriate fwmarks do not
enter the IPVS code.
I agree ! at least the modules are registered:
lvs1:~# lsmod
Module Size Used by
ip_vs_wrr 3200 2
ipt_MARK 2432 1
iptable_mangle 3072 1
ip_tables 16896 2 ipt_MARK,iptable_mangle
ip_vs 77664 4 ip_vs_wrr
Yep, you wouldn't see much otherwise.
>>Also your virtual service entry looks completely bogus, so I suspect
either your kernel or your user space binaries are wrong. What kind of
machine do you use? >>32/64bit?
cpuid shows me: "Intel(R) Pentium(R) 4 CPU 2.80GHz" , i believe that
this type of cpu has the 64 bit extension, not sure, i need to talk to
my vendor.
dmidecode output should be enough, however P4 is not 64bit, only has PAE
for 36bit memory addressing and probably EMT64.
>>Could you try a more recent debian kernel, please?
In the meantime i tried the 2.6.8-2-686 image instead of 2.6.8-2-386
with no success, unfortunality i was not able yet to build a kernel from
kernel.org,
apperently the way of compile from 2.4 to 2.6 have changed and i dont
have experience with it yet but i'm going to continiue
Is there a particular reason you need 2.6 kernel for your director
setup? The way to compile kernel did not really change that much. Try:
make menuconfig
make
This will generate you a vmlinux, modules and bzImage.
Use 'make help' to get an information on how to properly install your
kernel or do other funky things in your kernel source tree.
>>This looks correct. How does your resulting ipvsadm -L -n look?
In this sample i've set persistence but the same behaviour occure
without persistence.
Ok.
lvs1:~# ipvsadm -Ln

Weird! Your packet could not be properly decapsulated, see the IP
protocol entry? Please use at least 2.6.15 as kernel.
lvs1:~# iptables -L -t mangle -n -v

This looks correct. You don't have other netfilter entries in either the
filter or nat table?
>>Nope, not seen as such. Also please set the debug level in
/proc/.../vs/ to 5 or so and dump the kernlog entries here for the setup
and one request please.
Unfortunality "CONFIG_IP_VS_DEBUG" is disabled, think it's useless to
set debugging unless i have a recent / customized kernel running, will
come back.
Good, thanks. Cheers,
