upload files

[peterchu]

I want to let the users to upload .txt files from their pc to unix server , they use the ftp , it work fine but it is too danger as they can access the shell to read and even download files from the unix server , could suggest what other application is the most secure for user to upload files ? thx.

THere is no reason why your users need shell access to use "ftp". Just change the shell field in /etc/passwd to /usr/bin/false and add /usr/bin/false to /etc/shells.

They will still be able to ftp but not be able to log in.

If you want to stop them getting files from "ftp", have a look at /etc/ftpd/ftpaccess. In here you can limit which ftp commands the users can use. You can stop them using "get" if you want.

Hi,
Check the man pages of ftpaccess and the example file /usr/newconfig/etc/ftpd/examples/ftpaccess.

You might even want to try samba:

That way, the users just "map" a drive to your Unix server.
