dbus_bus_request_name（）：不允许连接拥有该服务
我在arm上构建了一个根文件系统。它应该运行dbus-daemon和avahi-daemon，但是当我尝试运行
avahi-daemon
$ dbus-daemon --system
$ avahi-daemon
Found user 'avahi' (UID 4) and group 'avahi' (GID 4).
Successfully dropped root privileges.
avahi-daemon 0.6.28 starting up.
WARNING: No NSS support for mDNS detected, consider installing nss-mdns!
dbus_bus_request_name(): Connection ":1.0" is not allowed to own the service "org.freedesktop.Avahi" due to security policies in the configuration file
WARNING: Failed to contact D-Bus daemon.

。在标准安装中，此文件包含其他配置文件，尤其是目录中的所有配置文件，其中存储了特定于服务的配置。这样DBus通常配置为Avahi： 我工作站的示例：$ cat /etc/dbus-1/system.d/avahi-dbus.conf <!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd"> <busconfig> <!-- Only root or user avahi can own the Avahi service --> <policy user="avahi"> <allow own="org.freedesktop.Avahi"/> </policy> <policy user="root"> <allow own="org.freedesktop.Avahi"/> </policy> <!-- Allow anyone to invoke methods on Avahi server, except SetHostName --> <policy context="default"> <allow send_destination="org.freedesktop.Avahi"/> <allow receive_sender="org.freedesktop.Avahi"/> <deny send_destination="org.freedesktop.Avahi" send_interface="org.freedesktop.Avahi.Server" send_member="SetHostName"/> </policy> <!-- Allow everything, including access to SetHostName to users of the group "adm" --> <policy group="adm"> <allow send_destination="org.freedesktop.Avahi"/> <allow receive_sender="org.freedesktop.Avahi"/> </policy> <policy user="root"> <allow send_destination="org.freedesktop.Avahi"/> <allow receive_sender="org.freedesktop.Avahi"/> </policy> </busconfig>
