之前使用 ssh 时,在将目录(不包含 .ssh)运行 rsync 到远程计算机的主文件夹后,会出现“权限被拒绝”的情况

我使用以下rsync命令将目录的内容放入移除机器的主文件夹中:

rsync -az directory/ user@IPADDRESS:~/

文件已顺利移至所有 4 台机器。移动文件后,当我尝试通过 ssh 进入机器时,出现以下错误:Permission denied (publickey).

directory/没有包含名为 的文件夹.ssh,因此我确信该authorized_keys文件没有被 覆盖rsync

执行后,可能是什么原因导致密钥被拒绝rsync

以下是详细的 ssh 输出(机器设置为接受 id_ed25519 密钥 - 无密码或其他密钥类型):

您发现,更改主目录的所有权(远离进行身份验证的用户)或模式(允许组或其他写入)将阻止 ssh 遵守 的内容~/.ssh。修复所有权和模式(改为 755 或更严格)将解决问题。
