Running Firefox remotely over ssh

Oct 11, 2011 in Howto, Remote administration

I’m connected to a remote machine over ssh (‘ssh -X remotemachine’).

I try to launch Firefox
user@linux-iek6:~> firefox

It launches, yes, but locally! Quite surprising to me.
OK, so I stop it and do some google searching…

Then, to make it run on the remote machine I command:

user@linux-iek6:~> firefox -no-remote
GConf-WARNING **: Client failed to connect to the D-BUS daemon:
Using X11 for dbus-daemon autolaunch was disabled at compile time, set your DBUS_SESSION_BUS_ADDRESS instead
GConf Error: No D-BUS daemon running

OK, it runs remotely now, but I stop it again and do some google search again.
Then, to get rid of that problem I first command: export $(dbus-launch)

user@linux-iek6:~> export $(dbus-launch)

and then:

user@linux-iek6:~>firefox -no-remote
*** nss-shared-helper: Shared database disabled (set NSS_USE_SHARED_DB to enable).

Some google again…
To get rid of also that I command:
user@linux-iek6:~>export NSS_USE_SHARED_DB=ENABLED

and then:
user@linux-iek6:~>firefox -no-remote

and now it runs on the remote machine without errors!

So I put all those in a script:

export $(dbus-launch)
firefox -no-remote &

That tiny thing does all the above nicely.
If you like to see what it’s doing add -x to the first line:

#!/bin/bash -x

openSUSE: Installing FreeNX

FreeNX: Full screen graphical sessions over network

FreeNX provides you with remote access to your graphical desktop from anywhere.
With the aid of FreeNX full screen graphical sessions can be accessed with even very low end cross platform clients.
This can be achieved also over poor network connections, even a GPRS modem connection works acceptably, over a 3G network the session feels like a local one a few years back.
You can suspend the sessions and resume them later. A session lost due to a network problem can usually be resumed, too.
SUSE includes FreeNX, so implementing it is easy. The FreeNX server package is installed normally on the server side and after that you run the setup script.
