[Script] Detect machines on LAN & adjust Deluge limits
Posted: Tue Jan 10, 2012 8:44 pm
Since I share my internet connection with other people I started using Deluge's bandwidth scheduler plugin to avoid hogging the connections (and avoid conflicts)
I set Deluge max to 60KBps, and on the evening hours it goes down to 40KBps.
But during the day, even this seemed wasteful if no one was home. Increasing the max (or setting it to unlimited) would make the connection useless for anyone working from home (and yes, sometimes that includes me)
So I made a small script to be run via cron say, every 5 minutes. It uses smbtree to count the number of Windows machines on the network, excluding the current host. When no other machine is found, deluge is set for a higher max download limit, and when other machines are detected, it reverts deluge to more modest settings.
Here is the code, which is also hosted at: https://github.com/acarroz/autobw
The script will only detect Windows (or Samba) hosts, but for my particular situation, I can live with that.
