我已经使用 cygwin 中的 openSSH 在 2 台 Windows 7 PC 之间设置了 ssh。RSA 身份验证已经过测试并可正常工作，因此我可以从客户端 ssh 进入主机，没有任何问题。
然后我使用以下命令在客户端上建立了隧道：
"ssh -f -N -L localhost:24800:user@host:24800 user@host".
理想情况下，我想运行一个名为 Synergy 的程序（连接到端口 24800），目标为“localhost”或 127.0.0.1 作为服务器地址，端口为 24800，synergy 超时，我的 cygwin 终端显示“写入失败：管道损坏”。这会导致隧道关闭。
不确定这是否有效，但如果我尝试：
$ ssh -vv -p 24800 localhost
我收到以下错误：
"OpenSSH_6.1p1, OpenSSL 1.0.1c 10 May 2012

如果您不熟悉 synergy，请见谅，但它只是一个在计算机之间共享鼠标和键盘控制的程序，我相当确定 synergy 不是问题所在。有人能告诉我该怎么做才能解决这个问题吗？
编辑： 根据 Joachim 的建议，我运行了：
ssh -f -N -L 24800:address:24800 user@address
这暂时解决了问题。但是，在我断开连接并尝试重新连接后，问题再次出现。
为了提供更多信息，我再次尝试调试，得到以下结果：

不幸的是，我仍然收到这个“写入失败：管道损坏”错误。
答案1
转发命令的正确语法是；
ssh -f -N -L 24800:address:24800 user@address
注意开始时删除的localhost（它是可选的）以及中间参数中缺少用户名（它应该只是主机名）
该命令将把本地主机 24800 端口的连接转发到远程主机的 24800 端口。
答案2
通过创建批处理文件来解决问题：
start C:\cygwin\bin\bash --login -i -c "ssh -N -L 24800:host:24800 user@host && C:/PROGRA~1/Synergy/synergyc -f localhost"
