Permission problem for a user

What is happening here is that the files you upload through FTP are owned by the user you used to upload with and they probably have rwx --- --- permissions so www-data can’t do anything with them.

I assume you use VSFTPD as the FTP server. In which case you can find a setting called local_umask in vsftpd.conf which probably equal with 077. That is the permission of the uploaded files.

You could change local_umask to 022 which would make the uploaded files have rwx r-x r-x and www-data would be able to read all the files.

Don’t forget to restart the FTP server after changing it’s configuration.

sudo service vsftpd restart

In a production environment I would not recommend setting local_umask in a way that gives write permissions automatically. I would give write permissions specifically by hand to the required directories and users.

If you are developing something and not deploying to a production environment you can set local_umask to 000 to speed up the process, but only do this if you doing it on a private development environment!

By adding both users to the same group and chowning it to that group.

One possible solution is that to change the group to your user’s group. That way www-data and tokar86a will both have write permission.

sudo chown -R www-data:tokar86a /var/www
