Regular monitoring of devices connected to the router:

[bibikalka]

Does anybody care to monitor which devices are connecting to their router?

Ideally, I'd like to do something like "arp -a" every few minutes via cron, dump that into a file. Then every day it'd get merged, and the number of identical ethernet entries would be counted. So as the daily output I'd get a list of ethernet addresses, and the number of times "arp -a" saw them.

Are there any existing addons that can be quickly transformed into such a monitoring tool?

If you haven't seen the existing addon's see the following list if something fits what you are looking for:

PS: And it may help if you include the router and firmware you are seeking to get a script working on. Certain addon scripts do not work on the 3006.102.x firmware.

I am not aware of any existing addon. I ended up writing my own script using various network commands like arp and brctl. The script is looking both for clients I expect to be online and for new unexpected clients online.

Could you share your latest script then? It could be a helpful starting point.

Suggest you start a thread on the add-ons area and I'll add it there and/or send directly.

I do have such functionality on my Gateway, it keeps data for a month back of what was connected, when, what traffic passed through it, etc... but honestly on a home network we don't really have random clients we don't know about. What is the purpose of this monitoring and why you need it done every few minutes?

I am gonna mess with parental controls via DNS to keep an eye on what kids are doing, thus if they are getting clever and randomizing ethernet addresses I need to be able to see that easily.

OK! I put a thread up, please contribute!

In development - addon to monitor connected devices:

Following the discussion in this link, @rung agreed to share his existing scripts that do this.
