FTP server to do...

[l_bratch]

I need an FTP server to do the following (which I used to be able to do on my Windows server!):

Have one public username and password, that anyone can log into if they have the password, and they can upload any file they like into the home directory.

However, they mustn't be allowed to delete any of the files in there, even if they uploaded them.

Back on the Windows server, the permissions were:
Files: Read, Create, List, NOT delete
Directories: Read, Create, List, Delete

This meant that:
a) They could add files to the public directory, but not delete them
and
b) They could delete empty directories, but if they had files in them, they couldn't delete the files or the directories.

So what I want to know is what FTP server on Linux will allow me to do this - a) is required, b) would just be nice.

Also, it must be one username only being used, as it is a public username.

Thanks if you can help! Without this I will need to rebuild the server with Windows to get this functionality!

Just exclude DELE from allowed_commands=

read the man page.

Thanks, but can this exclusion of DELE be applied to just my public user, because I definatly don't want a system-wide exclusion of DELE, as normal accounts still need it.

No problem
Just use
user_config_dir=/etc/vsftpd/users
and in that directory (/etc/vsftpd/users)
put a file with the same name as the username and put user spesific options there.
like

/etc/vsftpd/users/public:
allowed_commands=PORT,PASV,RETR,RMD

BTW, You don't need to even use allowed_commands

just set this to no:

Thanks a lot zeroclip, I'll give that a try when I can get to the server.

BTW, I'm not using virtual users, as all the man page tells me is to use PAM, and I never could work out what that was!

Linux-PAM - Pluggable Authentication Modules for Linux (Check out man pam)

Anyway. Making virtual users is pretty easy. Check out some of the great example configurations here:

You've just sorted all my Linux FTP problems, thanks a lot!
