NFS traffic with NFS share

[Joonas Kallunki]

I've tried to make a script for network acitivity or NFS share activity to prevent from going to automatic suspend. I still wan't suspend time to be enabled.
Using Ubuntu 12.04

Tried to reset the idle time counter with commands like:
xscreensaver-command -deactivate
qdbus org.gnome.ScreenSaver /ScreenSaver SimulateUserActivity
dbus-send --session --dest=org.gnome.ScreenSaver --type=method_call /org/gnome/ScreenSaver org.gnome.ScreenSaver.SimulateUserActivity

Not succeeding.

Any script or possible to caffeine be active while network traffic or traffic with nfs server?
