ssh - jenkins - 无法 ssh 到远程服务器( key - 权限被拒绝)，但可以从 cli 工作

Question

我在本地计算机上运行 Jenkins，试图找出服务器上遇到的远程 ssh 问题。我收到此权限被拒绝错误，这表明 key 有问题，但从 shell 上的同一用户帐户，我绝对可以连接。

这直接在 shell 上运行:

Jasons-MacBook-Air:~ jgoodwin$ echo $HOME
/Users/jgoodwin
Jasons-MacBook-Air:~ jgoodwin$ whoami
jgoodwin
Jasons-MacBook-Air:~ jgoodwin$ ssh -i /Users/jgoodwin/.ssh/id_rsa remoteuser@server 'echo success'
success

我相当困惑 - 我过去和 hudson 一起做了很多工作，我认为我在做这种类型的工作时没有任何问题。该错误表明按键有问题，但它们显然没有问题。

Answer 1

多种原因可能导致此行为，例如使用代理/钥匙串(keychain)管理器进行 key 缓存等。

我建议使用 -v 参数来比较两个输出:

ssh -v -i /Users/jgoodwin/.ssh/id_rsa remoteuser@server

这将让您以更详细的方式比较正在发生的事情。如果您仍然无法解决，请发布您的详细输出进行比较。

注意:您最多可以添加 3 个 -v 参数以增加详细程度。

更新:

@JasonG 据我所知，失败的详细信息是:

debug1:提供RSA公钥:/Users/jgoodwin/.ssh/id_rsa debug1:服务器接受 key :pkalg ssh-rsa blen 279 debug1:key_parse_private_pem:PEM_read_PrivateKey 失败 debug1:读取 PEM 私钥完成:类型 debug1:read_passphrase:无法打开/dev/tty:设备未配置

您的 key 似乎有密码，但无法输入密码，因为我们不在交互式 shell 中。标准 shell 中的命令行可能会受益于 Keycahin，它会为您“输入密码”。

如果您可以为成功的命令生成相同的详细信息，以便我们可以比较...
