lvs+ldirectored 为何看不到真实服务器列表?

手工启动ldirectord后,用ipvsadm查看,看不到真实服务器列表,为何? （不用ldirectord时,已实现均衡）。测试环境是LB上安装redhat9.0 ,真实服务器全是win2k,ldirectord.cf文件放在etc/ha.d/下,
ldirectord.cf的配置如下:
# Global Directives
checktimeout=3
checkinterval=1
#fallback=127.0.0.1:80
autoreload=yes
logfile="/var/log/ldirectord.log"
#logfile="local0"
quiescent=yes

# A sample virual with a fallback that will override the gobal setting
virtual=192.168.210.203:80
real=192.168.210.205:80 gate
real=192.168.210.206:80 gate
#fallback=127.0.0.1:80 gate
service=http
request="test.html"
receive="TEST"
scheduler=wlc
#persistent=10
#netmask=255.255.255.255
protocol=tcp
