Very useful permission control statements For vsftpd
Maybe some permissions may be unsatisfactory when using FTP. The hope I can provide is useful to you!
Let's take a look at the following examples:
1. Upload only. Cannot be downloaded, deleted, or renamed.
Cmds_allowed = feat, rest, CWD, list, MDTM, MKD, NLST, pass, PASV, port, PWD, quit, RMD, size, STOR, type, user, ACCT, APPE, cdup, help, mode, Noop, rein, stat, STOU, stru, syst
2. Download only. You cannot upload, delete, or rename a file. Write_enable = No
3. You can only upload, delete, or rename a file. Cannot be downloaded. Download_enable = No
4. You can only download, delete, or rename a file. Cannot upload.
Cmds_allowed = feat, rest, CWD, list, MDTM, MKD, NLST, pass, PASV, port, PWD, quit, RMD, RNFR, RNTO, RETR, DELE, size, type, user, ACCT, APPE, cdup, help, mode, Noop, rein, stat, STOU, stru, syst
The above two points are well controlled, but 1 and 4 are not so well controlled!

I have provided methods 1 and 4. Of course, you can also talk about how you implement the control of 1 and 4. We can communicate with each other!
Next I will talk about some specific parameters!

CWD-change working directory change Directory
List-list remote files column directory
MKD-make a remote directory to create a folder
NLST-Name List of remote directory
PWD-print working directory displays the current working directory
Retr-retrieve a remote file download file
Stor-store a file on the remote host

 

Dele-delete a remote file: delete an object
RMD-remove a remote directory Delete directory
Rename RNFR-Rename from
Rename RNTO-Rename

The above are common parameters. Let's take a look! The following are all the parameters in the column for your reference!
