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
-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.

Steps to Reproduce:
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.
