Ubuntu8网络配置nm-ifupdown-connection.c.82只读的解决方法


在网络配置时出现的错误：






step1：修改如下文件，将其中的“deny”改为“allow”
文件：/etc/dbus-1/system.d/NetworkManager.conf

<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd"> <busconfig> <policy user="root"> <allow own="org.freedesktop.NetworkManager"/> <allow send_destination="org.freedesktop.NetworkManager"/> <allow send_interface="org.freedesktop.NetworkManager"/> <allow own="org.freedesktop.NetworkManager.PPP"/> <allow send_destination="org.freedesktop.NetworkManager.PPP"/> <allow send_interface="org.freedesktop.NetworkManager.PPP"/> </policy> <policy user="haldaemon"> <allow send_destination="org.freedesktop.NetworkManager"/> <allow send_interface="org.freedesktop.NetworkManager"/> </policy> <policy at_console="true"> <allow send_destination="org.freedesktop.NetworkManager"/> <allow send_interface="org.freedesktop.NetworkManager"/> </policy> <policy context="default"> <allow own="org.freedesktop.NetworkManager"/> <allow send_destination="org.freedesktop.NetworkManager"/> <allow send_interface="org.freedesktop.NetworkManager"/> <allow own="org.freedesktop.NetworkManager.PPP"/> <allow send_destination="org.freedesktop.NetworkManager.PPP"/> <allow send_interface="org.freedesktop.NetworkManager.PPP"/> </policy> <limit name="max_replies_per_connection">512</limit> </busconfig>
