Jenkins 主从 : Key exchange was not finished, 连接已关闭

Question

我想将一个从站连接到 Master-Jenkins，但是在尝试连接时出现以下错误:

[05/02/18 15:26:59] [SSH] Opening SSH connection to <IP>
Key exchange was not finished, connection is closed.

节点配置:
- 启动方法:通过 SSH 启动 Slave
- 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 key 中

如果我以用户“jenkins”的身份在我的主人上做一个 ssh jenkins@<IP>我可以毫无问题地登录(公钥在从属设备上)。

为什么它不适用于“UI-Jenkins”。

Jenkins 版本:1.658

节点:Ubuntu 14.04

SSH-Slave 插件:1.26

Answer 1

那“解决”了这个问题:

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

更新:该问题已于 2017-04-29 解决“
