ssh -p 29418 user@samehostip 失败

  • 772

我在同一台主机上设置 jenkins 和 gerrit，我需要做的一件事是让 gerrit 和 jenkins 相互通信。

当我添加主机的 IP 地址（比如 10.25.26.27）时，我无法让 gerrit 触发器连接到 10.25.26.27。为了调试，我尝试了：

ssh -p 29418 [email protected] -v

已完成对 ssh-keygen 和复制 id_rsa.pub 的尽职调查。

上述命令的输出是：

但是，当我从另一个 IP 地址（例如 10.24.25.29）尝试相同的操作时，我可以成功连接。

我需要从同一主机运行 gerrit 和 jenkins。感谢有关调试此问题的帮助。

ssh jenkins gerrit

    服务器不接受您的任何密钥。检查您是否已授权服务器上的一个或多个 ssh 密钥。

    此外，您不能使用 DSA 密钥id_dsa，因为服务器不接受这种密钥类型。它必须是其他密钥类型之一。
