我在 Unix 服务器上安装了 Jenkins。
我正在尝试在 Windows 机器上安装从站。
我首先在 Windows 2008 服务器上尝试过，但失败了，然后我在 Widows 7 的机器上尝试过，但失败了。

Jenkins 服务器的 URL 是http://unixserver:9997

我通过防火墙在我的机器上打开了端口 9997，但没有成功。

我去服务器，在日志下，有一个我的奴隶名字的目录；里面有一个名为slave.log的日志文件

我尝试从 web 启动器或命令行启动从站：

java -jar slave.jar -jnlpUrl http://unixserver:9997/computer/slave1/slave-agent.jnlp -secret xxxxxxxxxxxxxxxxxxxxx

那里给出的错误是：

我遇到了同样的问题——从机会连接但立即失败；服务器日志中的错误是相同的。从站位于防火墙后面，所以我手动启动从站，但是在使用 ssh 或 jnlp 与 Jenkins 主进程在同一台机器上启动从站时出现相同的错误。

当我们在服务器上重新启动 Jenkins 进程时，问题就消失了。
