Bonjour Aliases ================== A project born of the burning desire to be backwards compatible -- served with a dash of bitterness. Motivation: CUPS 1.6 started to advertise printers as "printer @ server" instead of the old "printer @ server.domain.com", thereby making existing printer entries in MacOS clients unusable. This script eases the transition period between the two standards (at least it did for me and my users for all I know). I elaborated a bit on the corresponding Debian bug report, <http://bugs.debian.org/717245>. WARNING: At the moment, all server name patterns are hard-coded, so this very much only serves my needs. If Bonjour aliases sound like a good idea to you, I suggest you simply email me and I'll be happy to make this a all-purpose, all-weather software product. WARNING 2: This script places a heavy burden on DBUS. I have seen it crashing a couple of times on a machine that serves multiple interfaces (each Bonjour record needs to be duplicated for every interface). Caveat emptor! While I'm at it...

Quick Start -------------- On Debian, install the requisites and verify that it's doing what it's supposed to:: apt-get install libavahi-compat-libdnssd1 python-pip pip install pybonjour python bonjour_aliases.py See, if, on a different machine in the same physical net, you can see the aliases:: avahi-browse -a | grep [pattern] If happy, install daemontools or runit and symlink this directory under /etc/service:: apt-get install daemontools-run update-service --add /root/bonjour_aliases/ bonjour_aliases Check status, shutdown and start service:: svstat /etc/service/bonjour_aliases svc -d /etc/service/bonjour_aliases svc -u /etc/service/bonjour_aliases After a few days start sending friendly bug reports (to me) and possibly remind your users to switch their printer entries to the new convention. Long, Winding Story -------------------------------------------------------------------- This project currently solves one and only one scenario: It creates name-aliases to Bonjour records from already published records. Say you are running a printserver and it publishes your printers like this: printer1 @ my.domain You discover that, after an innocuous update, the very same printserver, for whatever reasons, starts publishing the very same printers with records named like this: printer1 @ my Being the good sysadmin that I am, I wanted my users to not suffer the inconvenience of discovering that they'd have to remove all Bonjour printers only to add them again (thereby possibly losing their precious settings). The project conveniently includes a 'run' file that's suitable for supervisors such as daemontools or runit.
