我正在寻找一些帮助，指向文档或联系人。
问题环境的上下文：MS Windows 7工作站必须在CentOS 6.5服务器上执行自制的bash脚本。这是通过使用已安装的OpenSSH客户端的自制MS批处理脚本完成的。
被叫bash脚本打开与其他CentOS 6.5服务器的SSH连接并执行命令
ssh userLogin@remoteClient "pidof gnome-panel"
如果从服务器X11环境执行此脚本，则此脚本正常工作（是的，此服务器具有X11环境）。但是，当它通过批处理脚本从Windows执行时，＆＃34; pidof gnome-panel＆＃34;的SSH子命令被封锁了。我使用SSH选项执行＆＃34; -vvv＆＃34; （编辑：完整日志）

我比较了这些捕获的日志，但我没有注意到观察到的行为的解释;日志的差异：
debug2: dh_gen_key: priv key bits set: 143/256
debug2: bits set: 508/1024
debug2: bits set: 544/1024
debug2: key: /home/snet/.ssh/id_rsa.pub (0x21933e0)
其中143,508,544和0x21933e0不同。
我绝对不明白为什么在这种环境下，SSH连接被阻止......
我将不胜感激。
谢谢。最好的问候，
