SSH密钥问题：不是RSA1密钥文件的未知密钥类型'----- BEGIN'

8

backuppc服务器能够以root用户身份登录到远程计算机并进行备份，但是如果我以backuppc用户身份登录并尝试使用同一密钥ssh进入这些计算机，则该密钥将被以下调试输出拒绝：

我知道~/.ssh在登录的计算机上检查权限是一个好主意，但是我的问题是我无法访问它。在我尝试登录的远程计算机上，这里.ssh是设置为的目录中的权限600。

drwxr-x--- 9 backuppc root      125 May 12 19:23 ..

/etc/hosts.allow并且/etc/hosts.deny没有被改变。

密钥自创建以来就不应该更改，并且不会以不正确的格式存储，因为本机已经使用了多年而不出问题。到目前为止，我已经重新启动了系统，希望能够对它进行修复，但是由于这些机器距离很远，因此生成其他密钥并不是真正的选择，因为生成新密钥并不是真正的选择。有谁知道我该怎么办？

任何建议将不胜感激。提前致谢。

您说您的密钥在〜/ .ssh。错误消息抱怨/var/lib/BackupPC/.ssh/id_rsa。您的主文件夹位于/ var / lib / BackupPC吗？
— 萨法多
是的。这是backuppc的工作方式。因此，以backuppc用户身份登录时，〜/ .ssh与/var/lib/BackupPC/.ssh相同。
— HAL9000 2014年
好，问一下。我从未见过一个帐户在/ var / lib中拥有其主文件夹。
— 萨法多
FWIW，“未知密钥类型'----- BEGIN'”消息及其后的消息不是错误消息。ssh只是在检查密钥文件是否为特定格式，并且它是冗长的，因为您要求它是冗长的。

抱歉，事实证明，backuppc配置中的其他位置正在使用其他名称登录到远程服务器。我所做的就是使用正确的用户名，并且能够登录。
