I'd be interested to see others thoughts on this too. I've not done much with wireless sniffing lately. My thoughts are the most straight forward way would be to use the pi as the access point. Likely there's a AP package that might do all this already but you could write some scripts to do it for you using hostapd as the AP software. Reading the hostapd log and emailing based on keyword criteria. Clunky but could work. At least for sending email alerts. SMS last I looked required signing up to a paid service. Far as I can tell off hand, any other way using a wifi adapter is going to require scanning and not really passively. Regards Chris Turner On 06/12/19 11:51, David Mehler wrote:

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. _______________________________________________ Blind-sysadmins mailing list -- blind-sysadmins@lists.hodgsonfamily.org To unsubscribe send an email to blind-sysadmins-leave@lists.hodgsonfamily.org
