Question

我在两台不同的机器上运行一个简单的命令：

ssh -vvvT git@github.com

在一台机器上，这是有效的。在另一台机器上，ssh失败并显示以下消息：

debug1: Server accepts key: pkalg ssh-rsa blen 535
debug2: input_userauth_pk_ok: fp bd:5a:d9:2b:d0:36:1c:f1:dc:f8:83:05:17:b9:04:e0
debug3: sign_and_send_pubkey: RSA bd:5a:d9:2b:d0:36:1c:f1:dc:f8:83:05:17:b9:04:e0
debug1: key_parse_private2: missing begin marker
debug1: key_parse_private_pem: PEM_read_PrivateKey failed
debug1: read PEM private key done: type <unknown>
debug1: read_passphrase: can't open /dev/tty: No such device or address
debug2: no passphrase given, try next key
debug2: we did not send a packet, disable method
debug1: No more authentication methods to try.
Permission denied (publickey).

我在两台机器上使用相同的私钥。私钥具有开始标记（即----- BEGIN RSA私钥-----）。私钥是在没有密码的情况下生成的。 .ssh目录的权限在两台机器上都是相同的（700）。两台计算机上的私钥文件的权限相同（600）。这是我的.ssh / config的内容：

Host github.com
    StrictHostKeyChecking no
    IdentityFile ~/keyfile

我完全混淆了为什么输出显示“缺少开始标记”，为什么它试图读取密码，当然为什么它根本就失败了。有什么我应该尝试帮助诊断这个问题吗？

Answer 1

密钥文件上没有标记表明它有密码短语。当ssh从文件中读取密钥时，它首先尝试在没有密码的情况下解释它们的文件内容。如果它无法理解文件的内容，它会要求输入密码并再次尝试读取该文件。你可以为ssh提供一个完整的无意义文件，它会在放弃之前要求输入密码：

换句话说，如果ssh提示您输入密码，并且您确信该文件不应该有密码，那么该文件肯定存在其他问题。例如，它可能会被截断或损坏。

ssh在一台机器上运行，但不在另一台机器上运行
