尝试使用火箭手部署网站时，SSH连接被取消

我正在尝试使用Rocketeer将Laravel站点部署到开发服务器（基于cPanel）。 我在维护SSH连接时遇到问题，服务器在初始build立连接后正在断开连接。

这个过程最初可以build立一个连接，而且我知道我的公钥authentication正在工作，因为我能够使用语法ssh [email protected]直接连接到服务器。

grepped上显示相关行的服务器上的日志文件如下：

从上面可以看出，build立连接后，连接会下降1-2秒。

• 初始化脚本在服务重启时运行重叠的服务器
• 在作为.wim一部分部署的Office 2010中出错？
• 我的文件/文件夹在Laravel框架有什么权限的git部署？
• 我无法将WIFI驱动程序添加到Microsft Deployment Toolkit
• ％systemroot％\ system32 \ GroupPolicy没有了

相同的部署脚本的configuration方式完全相同，但部署到不同基于cPanel的计算机上的登台服务器上执行成功。

这两个cPanel服务器已被configuration为相同的方式，但有可能是在两台服务器上configuration防火墙的方式可能有细微的差异，但是，我不知道如何可以区分两台机器上的防火墙configuration，以查看如果有任何细微的差别可能阻止dev服务器维护连接并执行部署脚本。

任何意见将不胜感激。

谢谢。

UPDATE

好的，有一些差异。

为了方便起见，我将调用有问题的服务器dev以及工作staging服务器dev 。

dev ：PasswordAuthentication yes

staging ：PasswordAuthentication no

dev ：X11转发没有staging ：X11转发是的

两者都有csf有一些区别：

dev ：DROP_OUT_LOGGING =“1” staging ：DROP_OUT_LOGGING =“0”

dev ：LF_SSHD =“20” staging ：LF_SSHD =“5”

dev ：LF_SSHD_PERM =“3600” staging ：LF_SSHD_PERM =“1”

dev ：CT_LIMIT =“300” staging ：CT_LIMIT =“0”

dev ：CT_INTERVAL =“120” staging ：CT_INTERVAL =“30”

dev ：CT_SKIP_TIME_WAIT =“1” staging ：CT_SKIP_TIME_WAIT =“0”
