hello sir, I am creating a LVS with two mail servers but got stuck in
between.Actually while compling the kernel for ipvs after patching ipvs from
your website.I used following commands:make mrproper,make oldconfig,make
xconfig these were working fine.But make dep && make clean && make bzImage&&
make modules&& make
modules_install,I faced a problem as:
make(3):***[ip_vs_sync.o]error 1
leaving directory /usr/src/linux/netipvs4/ipvs
make(2):*** [first rule]error 2
leaving directory /usr/src/linux/net/ipv4/ipvs
make(1):***[_subdir_ipv4/ipvs]error2
leaving directory /usr/src/linux/net
Then afterwards I had downloaded ipvsadm.src.rpm from web site.Then i used
rpmbuild --rebuild ipvsadm.src.rpm to convert it to a real rpm so that i can
install it.But it is exiting with comment that BAD EXIT FROM
/etc/tmp due to earlier errors
--(ipvsadm.o) make 1.
Why it is there.how to solve it .

you may have to use ipvsadm from the command line if the
configure tool you're using doesn't accept the commands

The timeout setting for TCP sessions, TCP sessions after receiving a FIN
packet, and UDP packets is the same both in the kernel 2.4 and 2.6.

I am not sure that it is a bug in LVS for 2.4, because we haven't touched
the code for service lookup and connection lookup for a while, and this
segment of code is frequently executed. If it were a real bug, a lot of
people would hit this problem too.
Could you please collect more information while running LVS for 2.4.x?
Thanks,

Which version of kernel source are you using? and which ipvs kernel patch?

Maybe you can simply download a clean copy of the Linux kernel 2.4.28
source. It has already included IPVS code, and you don't need to apply any
IPVS patch. Just configure IPVS and build the kernel.
Regards,
Wensong
sir,
I am using kernel version 2.4.20-8 and i had patched
linux-2.4.20-ipvs-1.0.9.patch.gz from website www.linuxvirtualserver.org .
