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!
