在使用rsync 同步文件的时候报错，之前没有问题，今天突然有问题了 甚是郁闷！
执行 命令：
rsync -az --delete --exclude-from=/www-cluster/rsync/www/exclude /www-cluster/data/test www-data@192.168.0.5::test
报错：
@ERROR: setuid failed rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
同时192.168.0.5 上有log
2012/10/24 02:44:01 [27543] 192.168.0.2 is not a known address for "bogon": spoofed address?

2012/10/24 06:44:01 [27543] rsync: setuid 501 failed: Resource temporarily unavailable (11)
正常的log
