How to identify Network Devices

Setup, Configuration and Use Beginners
1

Hi,
Just getting going re openHAB2,got it loaded and following the tutorials.

Network Binding - Search has found as series of network devices, but I do not know what they are relating to. Also, I do not recognise the range of IP addresses.

What do I need to do to identify these?

Any help would be appreciated.

Regards
Kevin

if you use some linux, you could identify the hostnames via nslookup.

if you are running openhabian, you could install dnsutils

sudo apt-get install dnsutils

and then

nslookup 10.211.55.02

Hi Joachim,
I am on Windows, so I tried nslookup via the command window.

 C:\>nslookup 10.211.55.2
 Server:  UnKnown
 Address:  fe80::21c:42ff:fe00:18

*** UnKnown can't find 10.211.55.2: Non-existent domain

Many Thanks, but not helping so far.

Do you own this LAN? You really should know all devices bound to your LAN, shouldn’t you? :wink:

As all these addresses are private, the most common way would be to lookup the dhcp table on your router, which should provide informations about the clients.

I find the Android app Fing to be very useful. I don’t know if there is an iPhone version. It will do an nap scan of your lan and tell you what most of the devices are hardware and OS wise. It will tell you their hostname if available.

For the few that it can’t ID, a search on the MAC can at heart tell you the manufacturer of the Network device which can be informative.

When all of that fails, you just need to go through the process of elimination. Hopefully you are only looking at a couple unknown devices by that point.

But I completely agree with Using. You should know what devices are on your network. Once you do figure it what they all are, update Fing and periodically scan to look for rogue devices.

Indeed can’t recommend Fing highly enough.I use it on my home, work and parents networks. I have it installed on various Android devices and an ipad at work (the ios version is still good, but not as good).

I also joined the crowd funded Fingbox they developed (recently arrived ) which add some nice features.

Hi Rich, benhelps, udo,
I always worry when I don’t know what an IP address is for - udo

I am running macOS Sierra 10.12.6 with Parallels 11 and Windows 10.

Installed Fing for Windows and it has identified the local network 10.211.55.xx, as the local domain for ‘Parallels’ on my Macbook Air. See below.

I will ‘ignore’ these network devices as far as openHAB2 is concerned.

Now trying to set up RFXcom - previously had it running successfully on Domoticz.

Thanks for the pointers.

Regards

Kevin.

Ah :slight_smile: yes, vm with it’s own network segment can be very confusing…

Too bad has taken the route of now charging for premium subscription for devices they have already sold. I have a new OH project that I completed yesterday that provides notification services when new device joins the network. I recall Fing wants $59/yr for basic services going forward.

You can still use it for free. I had some issues, though befory getting rid of the nag screen. I can’t remember, what I did, but I did not subscribe to anything and I am able to use the app.
