Title: For someone who wants to f### with IP numbers
Post by: rcjordan on January 29, 2020, 10:33:41 PM
Want to spend the better part of 2 DAYS identifying all the flora & fauna clinging to your local network?  This will help;

Resolving unknown devices (You're likely to have more than a few.)

Advanced IP Scanner. Install the program and click in the Green Play button Scan to start the network scan. This will return a list with all active network devices.  It will also show the manufacturer.  You'd think that knowing the manufacturer will always ID the device ....but NOoooo, the brand you know it by is likely missing.  For instance, instead of Samsung, you might get Murata Technology, Inc.

Sorry, I was a little off
I'm sorry, you must have mistaken me for someone who wants to f### with IP numbers, hhh.

Yeah, that's why I titled the thread as such. A hat-tip to the old me.

The smarthome stuff is really driving most of my interest in this. Not so much for the device installation ...though I did have to figure out DHCP to reserve IPs.  But failed or non-existent IOT security issues are almost flooding my news feeds. On hubitat, we use devices that were once phoning home to China but are now *supposedly* converted to local-only.  I'd like to verify that myself.

And then there's Louise's phone. With 50 apps installed. Makes me shudder.

The above PRTG ain't what I'm looking for, btw.

Oh yeah, and I'm hanging around with guys who post this kind of stuff daily

"OK, I see that port 8080 is a duplicate of port 80 and that port 8081 shows the Hubitat Diagnostic Tool but what is the purpose of having ports 443 (normally https) and 8443 open when they only return a few bytes ?"

I don't like being the stupidest guy in the room.

>>the old me.

That's what keeps me from getting further into home automation. It's like back when you had to get in and muck with serial port settings to get a printer to run or something. Of course, after initial success getting my printer to work on the network, it then stopped doing so and now has to be cabled in directly to print. At least that works without complication. Usually.

I kind of like doing things for myself.  I like driving my car, I like manual transmissions. My wife got rid of her bread machine and now cooks bread in the oven like grandma use to.  I could see diving into it and starting a "home automation" service for seniors though -- bridging the knowledge gap for profit.  Seniors are the most likely to benefit from automation and the least likely to take advantage of it.

We use prtg to monitor servers. Great at that job if you need to monitor anything. Maybe once you identify what you want to watch (or block), point a sensor at it?

When I say "home automation," I really mean "remote control home." So it's not that I want it to turn the lights on to a specific setting when I walking into the home, it's more like I want to be able to control the heat, turn on a few lights, detect water leaks and shut down the water and things like that when I am not there.

My Netgear R7800 is on the "needs replacing" list as it doesn't quite cover the far reaches of the house.  I want to go mesh.

In a Hubitat thread about routers, the Synology RT2600ac / MR2200ac combo was recommended ...mostly for its software.  In the screenshot, the UI showed a "Threat Prevention" panel with tracking of "malicious events."  So I went down the rabbit-hole and found this old review.

Synology RT2600ac Wi-Fi router review: for when too much nudity is never enough
https://www.afr.com/technology/synology-rt2600ac-wifi-router-review-for-when-too-much-nudity-is-never-enough-20170113-gtqqr6

In the review, the router flags a device on the network that apparently phones home.

For a mesh, the price is on the low end of average.

Killer feature. I really like Synology equipment.
