知道我为什么会这样做。我可以从本地计算机成功ping服务器。哪个sshpass显示有效输出，我使用Cygwin64。
$ sshpass -p loriK0ba scp SSUA-HG.war SSUA-RCd.war loki12:/tmp/ARUNKS
lost connection
要安装sshpass，我按照以下步骤操作，-V显示有效输出：
# IMPORTANT: You need to have sshpass utility installed on your local machine.
# ============================================================================
# HOW to get sshpass:
# STEPS: Run the following commands in Cygwin console window - This is a one time action.
# a. cd /cygdrive/c
# b. wget http://downloads.sourceforge.net/project/sshpass/sshpass/1.05/sshpass-1.05.tar.gz
# c. tar -xvzpf sshpass-1.05.tar.gz
# d. cd sshpass-1.05
# e. sh configure
# f. make install
# g. which sshpass
# ============================================================================
sh configure; sleep 5; make install; sleep 5; which sshpass
sshpass的版本是：
$ sshpass -V

PS：当我使用以下命令运行sshpass时，它没有＆＃39;错误输出但也没有在目标服务器上创建giga.txt文件（因此它没有达到/做任何事情）。同一用户（区分大小写）存在于本地框（运行Cygwin的位置）和目标计算机上。
sshpass -p loriK0ba ssh -q loki12 'rm -rf /tmp/ARUNKS/* 2>/dev/null; mkdir /tmp/ARUNKS 2>/dev/null'
