Limit vsftpd Writes

Question

I have a vsftpd installation running on Ubuntu 11.04. I have two users, an external user and an internal user. I only want the internal user to have write/upload permissions, but I want both to have read/download permissions. How do I accomplish this? I have already set write_enable=YES in the config, but that allows all users to write.

Haver a look at the user_config_dir directive.

This powerful option allows the override of any config option specified in the manual page, on a per-user basis. Usage is simple, and is best illustrated with an example. If you set user_config_dir to be /etc/vsftpd_user_conf and then log on as the user "chris", then vsftpd will apply the settings in the file /etc/vsftpd_user_conf/chris for the duration of the session. The format of this file is as detailed in this manual page

e.g.

user_config_dir=/etc/vsftpd/user_config

You should be able to create a file for the external user and specify

write_enable=NO

in it to stop their ability to write.
