如何确认SFTP档案传送? [英] How to confirm SFTP file delivery?

问题描述

我正在使用SFTP和非root用户的公共密钥发送文件，看起来像文件已发送，但是由于许可，我在目标文件夹上找不到它.

I am sending a file using SFTP and public key for non-root user, looks like the file is sent, but I cant find it on the target folder, maybe due to permission.

sftp> ls
sftp> put /tmp/testx
Uploading /tmp/testx to /folder1/target_folder
/tmp/testx                                 100%    5     0.0KB/s   00:01
sftp> get testx
Couldn't stat remote file: No such file or directory
File "/folder1/target_folder/testx" not found.
sftp> ls
sftp>

这是-vvv:

debug3: SSH_FXP_REALPATH . -> /folder1
debug3: Looking up /tmp/file_to_send
debug3: Sent message sender_host 4 T:17 I:2
debug3: Wrote 80 bytes for a total of 2653

目标目录

 drw-rw-rw-    1  0   0       target_directory

如何确保文件已交付，而没有服务器访问权限?

How can I make sure the file is delivered, without server access ?

推荐答案

您所能做的就是在上载文件时检查是否没有错误.以上就是SFTP服务器为您提供的所有信息.

All you can do is to check that there are no errors, when uploading the file. That's all information the SFTP server gives you.

使用命令行OpenSSH sftp客户端，可以检查其退出代码.

With command-line OpenSSH sftp client, you can check its exit code.

echo "put file.txt" | sftp -b - user@host
if [ $? -eq 0 ]
then
    echo "File uploaded"
else
    echo "File NOT uploaded"
fi

SFTP服务器很可能不允许您下载刚刚上传的文件.

It's perfectly possible that the SFTP server does not allow you to download a file that you have just uploaded.

这种行为有两个常见原因:

There are two common reasons for such behavior:

• 公共上载"目录.这是为了防止您下载其他用户的文件.
• 有一些过程可以立即选择上载的文件进行处理.
