Dear alls,
I solved my ftp problem that I wrote below.
First, there was originally some network problem
between Director and Client.
Between them even without LVS, telnet/ftp connection was impossible
and sometime very slow connected. ( I don't know why. )
Anyway, I removed their kernels and installed newly. After then,
telnet/ftp connection is woking well. and LVS is working.
Thanks for your guide anyway.
I learned much from you.

Thanks Joseph and Julian,
By your guides,
I upgrade the kernel and ipvs to kernel 2.2.15 version and IPVS 0.9.13.
I also checked "modprobe ip_masq_ftp".
`ip_masq_ftp' is well loaded.
The configuration is
A (Client)----- B (Director) ----- C (Server)
A: eth0= 211.169.226.144
B: eth0= 211.169.226.145
eth1= 10.1.1.1
C: eth0= 10.1.1.2
But, there are still some problems and phenomina as follows:
1. telnet and http access is OK from client
2. ftp login is ok. but "login is very slow" and "ls" command is not working.
3. I want to work telnet or web at the Director. But, After inserting ftp into
`ipvsadm'
The masqerading status at Director is as follows getting by "netstat -c -M".
IP masquerading entries
prot expire source destination ports
tcp 0:53.88 10.1.1.2 211.169.226.144 ftp-data -> 38122 \
(ftp-data)
tcp 0:13.56 10.1.1.2 211.169.226.144 * -> * (*)
tcp 13:54.95 10.1.1.2 211.169.226.144 ftp -> 38117 (ftp)
I am confused about it.
I hope your good guide again. :)
sincerely yours.
