Hello, I'm wanting to set up a wireless passive network monitor and i'd prefer to use a Raspberry Pi to do it. Here's my situation, I've got a wireless network and I'm needing to monitor it and to be alerted if certain devices log on to it. I'd prefer those alerts to come via either texts, emails, or both. I have a list of Mac addresses for safe devices that should be considered safe and no action should be taken should they be detected, but anything else should trigger an alert. Currently I have to check my cable-provider's router (I do not like it), to get this information, an RPI, one that is hooked up to the network would make this much easier. This is exclusively for my network, I'm not interested in addresses associated with other nearby networks, and i'd prefer to monitor both the 2.4 and 5GHz ranges. Does anyone have a Pi doing this? Thanks. Dave.
