I use this program to aggressively put my NAS Server to sleep when not required.

See original article for full description Force NAS Computer to Sleep when idle

IdleComputer_V2_Main
Monitoring Tab, selectable IP feature
IdleComputer_V2_Settings
Settings Tab, settings can be saved and sleep tested

New Features:

  • Select which Network Card to monitor.
  • Allow setting if Sleep or Hibernate is preferred.
  • Sleep/Hibernate test feature.

Bug Fixes:

  • Would not monitor traffic on a computer with multiple network cards or certain addresses.

Enhancements:

  • Moved program settings to own tab.
  • Save settings
  • Monitors sent/received data rather than just sent.

Requirements

Windows 10 (Should work on 7/8/8.1) and .net 4 runtime
