expect: spawn id exp4 not open

"expect "*""
原因:10.128.8.151上配置了SSH 用户等效性 移走即可
查到了一个明确的解释：Figured out why. I had generated ssh keys and copied it on to the destination machine. So there was no "Password: " prompt. Hence before send could complete, the ssh connection had closed. I deleted the ssh keys from the destination machine and ran the script again and observed no issues.（解释链接：http://stackoverflow.com/questions/1387848/issues-with-expect-send-spawn-id-exp4-not-open）
