https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D238406 Bug ID: 238406 Summary: Minor clarification for Section 9.1 of the Handbook Product: Documentation Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Documentation Assignee: doc@FreeBSD.org Reporter: rfg-freebsd@tristatelogic.com Section 9.1 of the Handbook gives nice examples of /etc/printcap files that= can be used for printing. The one for a networked printer says to include the D= NS FQDN of the printer. This isn't always either possible or desirable. Printers should generally = not be connected to the public routed Internet except in some very special cases because of the potential for security issues. Furthermore, in those cases where the IP address of a networked printer is one that is not publicly routable, that address should not appear in DNS records, according to publi= shed IETF guidance: https://tools.ietf.org/id/draft-ietf-dnsop-dontpublish-unreachable-01.txt Fortunately, it appears that at the point in the example /etc/printcap file where the user it told to substitute in the DNS name of the networked print= er, if the user instead substitutes in a traditional dotted quad representation= of the networked printer's IPv4 address, this seems to work just as well as if there had been a DNS fully qualified domain name for the networked printer substituted at that point in the /etc/printcap file instead. Readers of the Handbook should be advised of this alternative possible way = of designating a networked printer. Readers of the Handbook should perhaps also be advised that a networked pri= nter that can operate either in DHCP mode or in static address mode may possibly= be easier to deal with (for printing from FreeBSD) if the printer is assigned a static IP address. --=20 You are receiving this mail because: You are the assignee for the bug.=
