Question

我正在努力将我的Windows奴隶连接到Jenkins服务器（Linux），但没有运气。尝试了很多方法，很少解决，最后，我陷入了连接超时。我看到一些提到类似问题的帖子没有回应。

很少有观察来自我的结局：

Slave能够ping jenkins.com
在防火墙（入站和出站）规则下添加了端口55202以允许从站连接。
端口55202正在监听主人
另外，既然我使用windows作为我的奴隶，是否建议只使用java web start？
在奴隶中尝试过traceroute，但非常不一致。
master中的iptables是否受限于任何不同的子网？我猜主人没有响应，因此连接超时？

罗希特夏尔，

您能否检查一下这是否与您的情况相关？ Connecting Jenkins slave agent on windows failed with connection timeout

W.r.t。 2：如果您在同一个安全网络中工作，则可以完全关闭防火墙。
