jenkins - Jenkins Master-Slave：密钥交换未完成，连接已关闭

问题描述

我想将奴隶连接到 Master-Jenkins，但是在尝试连接时出现以下错误：

节点配置： - 启动方法：通过 SSH 启动从站 - 主机名：是 IP - 访问数据：我为 SSH 访问创建的用户 - > 公钥在从节点上的授权密钥中

如果我以用户“jenkins”的身份在我的主人上做一个ssh jenkins@<IP>我可以登录没有问题（公钥在奴隶上）。

为什么它不适用于“UI-Jenkins”。

詹金斯版本：1.658

节点：Ubuntu 14.04

SSH-Slave 插件：1.26

标签： jenkinssshjenkins-slave

解决方案

这“解决”了这个问题：

“解决方法是在 Jenkins Slave 的 /etc/ssh/sshd_config 中注释掉 MAC 和 KexAlgorithm 行并重新启动 sshd（在 Ubuntu 上重新启动服务 ssh）

更新：问题已于 2017-04-29 解决“

Jenkins master 无法通过 SSH 连接到 slave
