I'm trying to run dbus-send in a remote system but somehow I'm not able to run it. But the same dbus-send, if I run it in the local system, is working fine.

COMMAND:

ssh remote@xx.xx.xx.xxx "dbus-send --print-reply --dest=service.name /object/path object.path.Service.method string:"XYZ""

How can I run dbus-send command from the remote system?

SYSTEM INFO

Linux 3.13.0-29-generic Ubuntu i686 GNU/Linux

  • What is the error you are getting? since you are inside an SSH session (not a desktop session) dbus-send probably cannot find which session bus to connect to - it may be enough to set the DISPLAY variable to that of the remote session e.g. "DISPLAY=:0 dbus-send ..."; otherwise you will need to extract and set the actual DBUS_SESSION_BUS_ADDRESS – steeldriver Sep 2 '14 at 10:54
  • Actually I'm extracting DBUS_SESSION_BUS_ADDRESS and the value is unix:path=/run/user/1000/bus but still i'm not able to execute dbus-send – Thushi Sep 2 '14 at 12:33
  • That looks like a location not an actual address value - did you try the source command from @chaos's answer? – steeldriver Sep 2 '14 at 12:41
  • @steeldriver: Nope,It's not working.Error: cat: /var/lib/dbus/machine-id: No such file or directory bash: ~/.dbus/session-bus/-0:Permission denied – Thushi Sep 2 '14 at 13:37

dbus-send needs some evironment variables to connect to the dbus-session. First you need to estimate them. First ssh to your machine.

The $DISPLAY variable:

DISPLAY=$(strings /proc/$(pgrep -n Xorg)/environ | awk -F== '$1 ~ "DISPLAY"{print $2}')

The dbus session variables:

source ~/.dbus/session-bus/$(cat /var/lib/dbus/machine-id)-0

Now you can place your dbus-send command.

  • I'm setting DBUS_SESSION_BUS_ADDRESS. Along with that do I need to set DISPLAY variable also? – Thushi Sep 2 '14 at 12:37
  • @Thushi Yes, if you don't X11 initialization failed would occur. – chaos Sep 2 '14 at 12:41
  • I'm using mutter window manager.Is that fine with DISPLAY variable? – Thushi Sep 2 '14 at 13:30
  • @Thushi yes, that doesn't matter – chaos Sep 2 '14 at 13:31
  • K.But If I run that command I'm getting the following error. cat: /var/lib/dbus/machine-id: No such file or directory bash: ~/.dbus/session-bus/-0:Permission denied – Thushi Sep 2 '14 at 13:34

Why are tou using a semicolon ? this make a new command on local host.

try using

ssh remote@xx.xx.xx.xxx "dbus-send --print-reply --dest=service.name /object/path object.path.Service.method string:XYZ"

Also note, that /object/path is on remote host.

next try: try addind /usr/bin (if fact, on remote host, isseu which dbus-send to know exact path).

ssh remote@xx.xx.xx.xxx "/usr/bin/dbus-send --print-reply --dest=service.name /object/path object.path.Service.method string:XYZ"

can you provide error message ?
