Question

我想将一个奴隶连接到Master-Jenkins，但是在尝试连接时我得到了以下错误：

[05/02/18 15:26:59] [SSH] Opening SSH connection to <IP>

节点配置： - Start-Method：通过SSH启动Slave - 主机名：是IP - 访问数据：我为SSH Access创建的用户 - ＆gt;公钥在Slave Node

上的授权密钥中

如果我作为用户“jenkins”在我的主人身上并且做ssh jenkins@<IP>我可以登录没有问题（公钥在奴隶上）。

为什么它对“UI-Jenkins”不起作用。

Jenkins-Version：1.658

节点：Ubuntu 14.04

SSH-Slave插件：1.26

Answer 1

那＆＃34;解决了＃34;问题：

＆＃34;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上重启服务ssh）

更新：问题已于2017-04-29＆＃34;

解决

Jenkins master fails to connect to the slave over SSH

Answer 2

在目标节点上执行此命令。

sudo -i su -c'sed -i -e“ s / MACs / MACs hmac-sha1，/ g” / etc / ssh / sshd_config;服务sshd重新启动”

Answer 3

我想将我的经验投入到这个线程中：我的环境有Windows主服务器以及混合的Windows和Linux代理。即使Master将'jenkins-agent'和其他支持文件推送到该代理，一个Windows代理仍拒绝连接到master。

此代理安装了6个不同版本的JDK和JRE。我卸载了所有它们，仅重新安装了我们需要的最新JDK，并设置了JAVA_HOME。这解决了连接问题。

Jenkins Master-Slave：密钥交换未完成，连接已关闭
