我爲服務器A1和我的筆記本電腦L設置了無密碼身份驗證。ssh無密碼登錄失敗,權限ok

我想爲另一臺服務器A2設置相同的值。

所以我複製A1的文件~/.ssh/authorized_keys中打印的公鑰,並且我在A2的文件~/.ssh/authorized_keys中打印了相同的公鑰。

權限沒問題,但筆記本電腦L和服務器A2之間的身份驗證不起作用。

以下是輸出ssh

您是否找到解決方案? – Robert

是的,我不記得了,但我認爲這是一個許可問題。他們看起來不錯,但我摒棄了所有的程序,以正確的方式設置權限,然後它就起作用了。 –

問題: 的Ubuntu的sshd不支持ECDSA-SHA2-nistp256 KexAlgorithms

如果你有機會到主機正在運行的sshd檢查生成的密鑰您認證日誌文件,我想你會有這樣的事情: userauth_pubkey:不支持的公鑰算法:ecdsa-sha2-nistp256

解決方案: 使用最近的OpenSSH版本
