Yes - you probably also want chmod 770 /usr/local/proftpd/etc if it doesn't have those modes already. Also, you need to check that this does not prevent the proftpd program from reading its own config file. I don't know if it runs as root at that point or not. If it runs with non-root permissions as it starts, you'll have to be sure it has permission. If there is no sensitive information there you could just allow 'other' read access. -- Les Mikesell lesmikesell@xxxxxxxxx
