 |
|
Hi everybody, i have trouble getting avahi-daemon to run, when i check rc-service avahi-daemon status it say it's running | Code: | rc-service avahi-daemon status
* status: started |
but when i try to avahi-browse -a
| Code: | avahi-browse -a
Failed to create client object: Daemon not running
|
So i try manualy: | Code: | sudo rc-service avahi-daemon start
* WARNING: avahi-daemon has already been started |
or | Code: | avahi-discover
Failed to connect to Avahi Server (Is it running?): org.freedesktop.DBus.Error.Spawn.FileInvalid: Cannot do system-bus activation with no user |
my info https://bpa.st/F2JA
I have another gentoo machine, and avahi just works fine. Just don't know where to look after hours and hours finding info in the net.
thanks.

| Can you please confirm that the `dbus` service, which provides the D-Bus system bus, is actually running? |

Okay, great. It's good that you checked that; in future, when you post questions about a problem, could you please make sure to say what checks you've already done?
Have you also checked that there's actually an `avahi-daemon` process running, e.g. by doing `pgrep -a avahi-daemon`? The service might be immediately crashing after OpenRC considers it to have been successfully started, which will leave OpenRC thinking it's still running when it's not. |

Thanks for the reply, i don't know why dbus is so important for avahi to work, i didn't say anything about dbus because it's beyond my knowledge. I also check my rc.conf but nothing that i can tell if is off or not.
| Code: | pgrep -a avahi-daemon
1874 avahi-daemon: running [Gent-msi.local]
1875 avahi-daemon: chroot helper |
This is what i already try and search over the internet, also some tweeks in nnsswitch.conf. "hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4"
| Code: | avahi-browse -a
Failed to create client object: Daemon not running |
| Code: | avahi-discover

D-Bus provides a standard interface for software to query and control various aspects of the system, e.g. hardware and services, without being tied to any particular user environment (GUI / WM / DE etc.). Prior to moving from Void to Gentoo, i wrote a quick introduction to why D-Bus exists and what it does: https://github.com/flexibeast/guides/blob/master/dbus.md
i've just done some experiments on my own system, and i too get this:
| Code: | avahi-browse -a
Failed to create client object: Daemon not running |
when there's no socket "/var/run/dbus/system_bus_socket". Does that file exist on your system? |
