为什么这个 ssh 密钥文件在 Windows/Filezilla 上工作，而不在 linux/命令行上工作？

Question

我使用名为 mykey.ppk 的密钥成功连接到 Windows 上的 FileZilla，

我正在尝试使用该密钥在 Linux 上的 Jenkins 管道中上传文件。

我根本无法让该文件在 ubuntu 中工作 20:04

我使用 PuttyGen 将文件转换为名为 mykey_open.ppk 的 open-ssh 格式文件，如 https://serverfault.com/questions/1004774/load-key-privkey-ppk-invalid- format （加载 > 转换菜单 > 导出 OpenSSH 文件）

我将文件的权限设置为 600，所有者为 jenkins:jenkins

我输入了以下命令在 putty 上，

ssh -Tv [电子邮件受保护] -i ./mykey_open.ppk

结果：

debug1: Trying private key: ./mykey_open.ppk
Load key "./mykey_open.ppk": Permission denied
debug2: we did not send a packet, disable method
debug1: No more authentication methods to try.
[email protected] : Permission denied (publickey).

以及 Jenkins 管道中：

sh 'ssh -Tv [email protected] -i ./mykey_open.ppk'

给出：

Transferred: sent 2520, received 2244 bytes, in 0.4 seconds
Bytes per second: sent 7154.6, received 6371.0
debug1: Exit status 1
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
ERROR: script returned exit code 1
Finished: FAILURE

我还尝试使用 pipeline 命令

def remote = [:]
remote.name = "myremote"
remote.host = "myremote.site.io"
remote.allowAnyHosts = true
    withCredentials([sshUserPrivateKey(keyFileVariable: 'identity', passphraseVariable: '', usernameVariable: 'myuser')]) {
        remote.user = userName
        remote.identityFile = "mykey_open.ppk"
        stage("SSH Steps Rocks!") {
            sshPut remote: remote, from: 'myfile.zip', into: '/myremote.site.io/path/to/folder'
        }

给出

找到解决方案：使用sftp命令而不是ssh。

但 sftp 通常依赖于交互式命令：您输入 sftp，然后您会收到 sftp> 提示，输入诸如 put、之类的命令get 等。

在编程上下文中使用该命令有一个解决方法：

echo put localfile.txt path/to/local/remotefile.txt | sftp -i keyfile.ppk [email protected]

在 Jenkins 管道的特定情况下，这将变为：

sh 'echo put localfile.txt path/to/local/remotefile.txt | sftp -i keyfile.ppk [email protected]'
