Data directory needs more secure permissions
When installing istatserver, the permissions on /usr/local/etc/istatserver are 0755. Since /usr/local/etc/istatserver/istatserver.conf is also 0755, this means anyone with shell access to the server can read the conf file and pair iStat 3 to that server. This does not seem desirable.
Since the istatserver directory is already owned by istat:istat, it would be best to make sure the installer changes the permissions on /usr/local/etc/istatserver to 0750.
In fact, shell access isn't even necessary. Since the daemon installs in a standard location, one could upload a script to a web server which is running istatserver and retrieve the pairing PIN by reading or even outputting the contents of the config file, if the web server isn't configured to jail web access to specific directories (which is often the case).
