Well i'm too lazy to type that by hand ! I see what you mean i actually did -s 
lwc instead of wlc and the soft looked blindly for a ip_vs_XXX.o , hehe :) just 
like modpobe toto will load toto.o --- convinced ?
and this is THE machine that kept the record of uptime with a warez ftp on it 
:) (we got hundred servers all over paris ..)
now i noticed when doing ipvsamd -D and -A many times and especially when i did 
a -D whith the interface down it didnt delete the entry even after restarting 
the device in question ...

i'll look deeped into it ASAP , i bleive i used whatever was the latest stable 
tarball -- a week ago ...

hmmm hold on

/home/admin/work/ipvsadm
/home/admin/work/ipvsadm-1.17.tar.gz

:)Hmm, this is not so nice. Eventually I want to rebuild you system
