cygwin rsync协议错误

这是我在Windows上运行的命令.我看到它正在建立与远程机器的连接,但它在验证之后和传输文件之前就已经死了.什么可能导致这个问题？

rsync -vvvv localfile REMOTE-HOST:~/

FILE_STRUCT_LEN=16,EXTRA_LEN=4
cmd=<NULL> machine=REMOTE-HOST user=guest path=~/
cmd[0]=ssh cmd[1]=-l cmd[2]=guest cmd[3]=REMOTE-HOST cmd[4]=rsync cmd[5]=--server cmd[6]=-vvvvv.Lsf cmd[7]=. cmd[8]=~/
opening connection using: ssh -l guest REMOTE-HOST rsync --server -vvvve.Lsf. "~/"
note: iconv_open("UTF-8","UTF-8") succeeded.
