RHBA-2010:0034 - Bug Fix Advisory

Topic

Updated avahi packages that address two bugs are now available.

Description

Avahi is an implementation of the DNS Service Discovery and Multicast DNS
specifications for Zeroconf Networking. It facilitates service discovery on
a local network. Avahi and Avahi-aware applications allow you to plug your
computer into a network and, with no configuration, view other people to
chat with, see printers to print to, and find shared files on other
computers.

This update fixes the following two bugs:

• previously, avahi published a static SSH-SFTP service by default,

regardless of the machine and regardless of whether an ssh server was
running or not. As a result, all Red Hat Enterprise Linux instances also
running Avahi appeared in the LAN listings of file browsers and file
managers (eg "Places > Network" in Nautilus or "Go > Network Folders" in
Konquerer) even if they were not acting as file servers. This update still
includes a static SSH-SFTP service but it now ships as a deactivated
example service (ie, is not published by default). The static SSH-FTP
service can be activated manually, but systems running Avahi no longer
appear in file manager LAN listings by default. (BZ#219143)

• previously, running the Avahi init scripts with a "status" argument

resulted in a return code of 0, regardless of whether the daemons are
running or not. This update corrects that: a missing avahi daemon now
results in a failure return code (1) as expected. (BZ#232161)

All avahi users should install these updated packages, which address these
issues.
