Start a service in docker container failed,with error: Failed to get D-Bus connection: No connection to service manager

不羁岁月 提交于 2019-12-03 00:12:44
I installed docker image and built a image successfully. When I ssh to the container and run the command service xxx start , an error popped: service nginfra start Redirecting to /bin/systemctl start nginfra.service /sbin/service: line 79: /bin/systemctl: No such file or directory Actually, fakesystemd is installed in the container instead of systemd . So I removed fakesystemd and installed systemd with the command: yum swap -- remove fakesystemd -- install systemd systemd-libs But I still can't start the service: service nginfra start Redirecting to /bin/systemctl start nginfra.service Failed

MPRIS + Python (dbus): reading and writing properties

一笑奈何 提交于 2019-12-02 23:21:39
I have already checked this link: How to handle properties of a dbus interface with python . However, that only lists an API... but I don't know where that API comes from. I just started working with dbus (pretty excited about this, to be honest ^__^ just not too happy with the documentation I've found) on python and I was wondering if I could just get some sample code. I'm using MPRIS specifically for Rhythmbox, although it 'should' be the same for all. I know I can access and have fun witht he methods by doing the following: import dbus bus = dbus.SessionBus() proxy = bus.get_object('org

D-Bus equivalent for Windows

Anyone know of a Linux/D-Bus sort of mechanism for Windows? Thanks Choose your poison: http://msdn.microsoft.com/en-us/library/aa365574%28VS.85%29.aspx The following IPC mechanisms are supported by Windows: Clipboard COM Data Copy DDE File Mapping Mailslots Pipes RPC Windows Sockets The closest to DBus is COM. Ioan The reference D-Bus implementation natively supports Windows. Previously, the WinDBus project could be used. There is no need for equivalents if you want to use D-Bus. user3587151 windbus is now part of the official DBus releases, see: https://www.freedesktop.org/wiki/Software/dbus/

How to use the existing services in DBus?

扶醉桌前 提交于 2019-12-02 09:31:37
I am able to use the dbus commands like dbus-send and etc. But i am not getting how to use the api's of dbus efficiently to write sample applications. Can any one please tell me how to receive the data from the dbus. I am not getting how to use the existing services in dbus like org.freedesktop.NetworkManager Please tell me the proper way to access and use the services of dbus. Please post some sample examples and also suggest me what are the rules we have to follow while using a service. i am looking for 1)How to add our own service to the system / session Bus.At the same time,how to receive

How could run python dbus on windows?

I'm new to dbus concept and I programming with python 3.5.1 on windows, i read many documents and can't figure out is dbus can work on windows? if so which module I've tried pydubs, pymodbus,... please help me should I go to Linux or there is a solution? As far as I know, there is no standard Python Dbus library for Windows. You can use this link: the only link I found that makes it possible but there aren't any Stack Overflow threads/questions about Python Dbus code on Windows. http://poquitopicante.blogspot.in/2012/07/building-dbus-python-on-windows-with.html Using it for anything other than

QtService application cannot connect to system bus when running as a service

柔情痞子 提交于 2019-12-01 17:54:25
I have recompiled Qt with integrated dbus for windows. Further, I have implemented a QtService application which registers a service and an object at the system bus as follows: QDBusConnection::systemBus().registerService("com.mycompany.Configuration"); QDBusConnection::systemBus().registerObject("/com/mycompany/Configuration/MySetting", myObject); Now when I am running the service application with the -e parameter (running as regular application) it works fine and both dbus-monitor and qdbus --system show me the registered service and object. However, when I am running the application as a

How to Pass a structure as a parameter in a dbus signal?

北慕城南 提交于 2019-12-01 14:26:42
How to pass a structure as a parameter to a dbus signal through command line? Dbus-send --system --type=signal / com.example.signal_name string:"hello" In the place of string, I want to pass structure foo. typedef enum {MODE1, MODE2, MODE3} MODE; typedef enum {TYPE1, TYPE2} TYPE; struct foo { MODE mode; TYPE type; }; Firstly, you need to work out how to represent that structure as a D-Bus value . Its most likely representation would be as a value of type (uu) where the first u is the mode (using some well-defined and stable mapping of C enum values to integers ) and the second u is the type .

selective D-BUS signal emitting from ObServer (unicast signal)

微笑、不失礼 提交于 2019-12-01 11:28:52
I have a situation where I have a single ObServer object and a set of Clients. ObServer and clients connected through D-BUS (IPC). ObServer has generic interface for all clients. But, time to time ObServer needs to notify clients about some events. Clients listen for a ObServer Generic interface signal OnNotify(). Question: How to emit D-BUS signal (OnNotify()) from ObServer to specified client (instead of broadcast to all) ? p.s Qt D-BUS used for wrapping but any approach are welcome. You can't. Signals are received by all clients that have registered for that signal on a DBus interface. You

Why does GObject method still get called even if callback arguments don't match those in XML?

Suppose I have a method like this <interface name="org.Test.ChildTest"> <!-- set_age(guint32 new_age): sets new age --> <method name="set_age"> <arg type="u" name="new_age" direction="in"/> </method> In my table of methods I have: { (GCallback) child_test_set_age, dbus_glib_marshal_child_test_BOOLEAN__UINT_POINTER, 0 } and the right GObject method signature is: gboolean child_test_set_age (ChildTest *childTest, guint ageIn, GError** error) Why does my method, child_test_set_age() , still get called on DBus even if the callback arguments don't match the one specified in my XML? For example if I
