我需要在服务器 A 上安装一个存储，以便从服务器 B 可以通过 scp 将文件从 B 发送到 A。
在服务器 A 上，我尝试将存储安装为：
# mount.cifs //u999999.your-storagebox.de/backup /storage/driveNumber -v -o user=u999999,pass=typeUrPasswordHere
挂载结果为：
# ls -la /storage
total 8
drwxr-xr-x 3 root root 4096 Feb 2 17:17 .
drwxr-xr-x 23 root root 4096 Feb 2 17:16 ..
drwxrwxrwx 2 999999 999999 0 Feb 3 17:26 bx20_133060
但是，当我尝试从服务器 B（现在是我的盒子）发送文件时，我得到以下信息：
$ scp -v -p -P 45789 mysql-incremental.tar.gz [email protected]:/storage/bx20_133060

我做错了什么以及如何做对？
答案1
对于只是使用，scp 我首先会直接在服务器 A 和服务器 B 之间验证它，然后将您storagebox排除在外。
从每个服务器尝试类似的事情 scp somefile.txt otherserver:/home/gtludwig/
ssh如果这不起作用，那么问题就更简单了，并且scp与每个服务器之间的安全性有关。
但我怀疑问题在于用户、文件和目录权限在storagebox您要安装的服务器之间没有同步。如果storageboxcifs 是某种存储设备，则尤其如此验证与一些 Windows 域服务器...从技术上讲，这将是服务器 C。还知道 的管理员storagebox可以简单地限制可以安装的设备，storagebox无论用户名和密码是否正确storagebox。这相当于将 linux NFS 导出限制到给定主机，如 中指定的那样/etc/exports。
但从您提供的信息看来，发生的情况是您已经storagebox安装了server_A，并且 mount.cifs 是在用户下定向的u999999 ，但是在使用时，scp您在用户下通过 SSH 连接到 Server_A，slammer因此权限被拒绝。
从 Server_A 首先确保storagebox已成功安装，然后作为用户，u999999您可以成功地将文件上传到storagebox.然后尝试scp输入 server_A as u999999，或者确保您使用的用户名/用户 IDscp与用于挂载 cifs 共享的用户名/用户 ID 相同。
