Description of problem: Suggestion for documentation improvement in: The Official Red Hat Linux System Administration Primer - Printers and Printing - Printer Sharing and Access Control It is said that RedHat printing systems listens on port 631. For a remote linux printer, the "lpd" (LPRng) listens on port 515. It would be useful to say that by adding in the file /etc/sysconfig/ipchains the line: -A input -s 0/0 -d 0/0 515 -p tcp -y -j ACCEPT port 515 is unblocked throught the firewall (if installed). I mention this because RedHat 7.3 and lower don't have the application redhat-config-securitylevel, and gnome-lokkit does not allow to open extra ports, which adds a stupid burden on setting up a remote printer. Thank you for the documentation. In general it is very usefull for intermediate users as myself.

Thank you for your feedback. The next version of the System Administration Primer will be taking a different approach to documenting print-related issues in preparation for a more in-depth treatment in a later edition. Because of this change, the issue you raise is not directly relevent for the upcoming edition. Therefore, I am closing your report with a "deferred" status, to reflect the necessity to keep the issue you raise in mind when work on this chapter continues.
