Public bug reported:
Binary package hint: bash-completion
The latest version of bash-completion, synced into lucid, calls the
following from /etc/bash-completion in _known_hosts_real():
avahi-browse -cpr _workstation._tcp
which is probably great on a small home network with 2 machines.
However, there are typically over 100 Avahi/Bonjour devices on the same
broadcast network as my laptop, and because they are generally laptops
they are appearing and disappearing on the network very frequently,
which means avahi will often hit its internal timeouts when trying to
resolve things that are going away. This adds up to the above avahi-
browse command always taking at least 5 seconds, which is really quite a
lot of time to add to a tab completion.
Secondly, something is wrong with the way it is being called, as the
first thing it always prints, to stderr, is:
WARNING: Unhandled message:
interface=org.freedesktop.DBus.Introspectable, path=/, member=Introspect
(stderr is not redirected away by the bash-completion script). Depending
on how many hosts have timed out, I will then get for each one, an error
like:
Failed to resolve service 'bob-laptop [00:11:22:33:44:55]' of type
'_workstation._tcp' in domain 'local': Timeout reached
All in all this makes for a very unpleasant experience if you are a
sysadmin who uses ssh constantly!
avahi is a great feature, but please make this silent and optional for
those of us whom it hurts!
