急救!!!!!!heartbeat问题.......

我在我的机子上加了个网卡.LYX78:eth1 10.2.10.2 eth2:172.16.1.78,LYX84:eth0 172.16.1.84,eth1:10.2.10.1.在两台机子上的ha.cf,haresources,authkeys配置都是一样的.如下:
ha.cf:
debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility local0
keepalive 2
deadtime 30
warntime 10
initdead 120
udpport 694
bcast eth1 # Linux
ucast eth1 10.2.10.1 10.2.10.2
auto_failback on
watchdog /dev/watchdog
node LYX84
node LYX78
ping 172.16.1.180
respawn hacluster /usr/lib/heartbeat/ipfail

haresources:
LYX84 172.16.1.85/24/eth0/172.16.1.255

authkeys:
auth 1
1 crc
#2 sha1 HI!
#3 md5 Hello!

在LYX84上运行heartbeat,结果是:

LYX78 与 LYX84在eth1上是用交叉线相连的.且用主机名可以互ping通.LYX78是RH9.0,LYX84是FC4的系统.
为什么不能监测出LYX78是活的啊.是我配置有问题还是我的环境有问题?麻烦高手帮忙看下..Thank you very much!
