# HTPC suspend script #
# author: Hans van Schoot #
###########################
# TODO list: build in a check for ftp server activity
# turn the script into nice program with modules
# The purpose of this script is to suspend the machine if it's idle.
# the script checks:
# - if a lockfile is present (this way the script can be bypassed when needed)
# - if XBMC is running, and if it's playing
# - if there is keyboard or mouse activity
# - if transmission download speed is too low to keep the system awake for
# - if there are samba shares in use (READ ON FOR THIS!)
# To function properly this script needs a couple things:
# - from apt-get: xprintidle
# - from apt-get: transmissioncli
# - the gnome-power-control script (installed in /usr/bin) from AgenT: http://ubuntuforums.org/showpost.php?p=8309702&postcount=16
# - xbmc web server enabled without a password (can be found in xmbc settings under network)
# (if you don't need xbmc, you can comment out the xbmc section or put the xbmcDelay on 0)
# - to be able to use "sudo smbstatus" (so rootaccess, or if you run the script on userlevel this can be fixed by adding
# "your_username ALL=(ALL) NOPASSWD: /usr/bin/smbstatus" visudo (run "sudo visudo" in terminal))
# the same goes for sudo /usr/sbin/pm-suspend !!!!! the suspend command!

# 1. connect to the share with another computer
# 2. use "sudo smbstatus" in console
