How to list all devices on the Windows or Linux home network

How does my Android phone figure out what's on my network without logging into the home router?
I can see 8 devices on the network when I log into the admin account of the router using a web browser on a laptop.
However, I can see all those devices from my Android phone WITHOUT logging into the router, simply by using "Fing" Android freeware:

My question?
How does the phone see both wired & wireless devices (such as a wired printer & a wired Ooma) without logging into the router?
More importantly, how can I get Windows & Linux to see the same 8 or 9 devices on my network that the phone sees *without* logging into the router's admin account?

It seems that there are versions of the Fing app available for desktop operating systems too . The 'Fing for Linux' option lists
RPM 64 Bit or 32 Bit DEB 64 Bit or 32 Bit TGZ 64 Bit or 32 Bit
there may already be a 'build' of the tarball for your distro (possibly in the 'testing' or 'user-contributed' or other 'unofficial' repositories).

The web page was nicely set up in that it provided the URL: $ wget "

Well, I'm getting nowhere so, I'll ask how to use it and google some too.
How do I use fing on a typical linux computer on a home network?

Many many errors that could have been avoided but he finally learned.
So the key file is in /usr/local/lib/fing/fing.bin
What does route -n tell you? Does network 192.168.1.0/24 exist? What does ifconfig -a say?
It cannot find your network. That could mean many things. It could be incompetently written. It could be you have no network.
Note it worked for me-- wired network
It would be a lot better if it actually had source code. One could figure out what it was doing.

It works now that I have the syntax figured out!

Windows & Linux FINALLY matches what Android & iOS reported all along for *all* devices attached to the network! Thanks to Whiskers for suggesting Fing on Linux/Windows for listing out all the connected network devices.

Not a single other Linux or Windows command worked to date other than Fing. For example, neither arp-scan nor nmap worked to list *all* the devices on the network that fing on unrooted Android and iOS reported. $ nmap --script broadcast-dhcp-discover -p67 192.168.1.0/24 $ sudo arp-scan --interface=wlan0 --localnet
Yet fing worked perfectly once installed on the desktop computer!
15:30:49 > Discovery round completed in 45.527 seconds.
15:30:49 > Network 192.168.1.0/24 has 11/11 hosts up.
15:30:17 > Host is up: 192.168.1.6 HW Address: 8C:29:37:AA:21:22
Notice that Android phone (192.168.1.5 & 192.168.1.8) has two IP addresses!
Here is the fing result on the phone at the same time!

Finally computer results match unrooted iOS & Android results!

Please ignore this thread.
That final report was meant for a different set of newsgroups.

Since we are talking about fing, is it possible to have fing return a chart like the above but including the vendor (if known) and the Client ID? I've been having to do it manually and it's a pain.

Your name of interest to me as I consult part time for Lucite International. I see you are making products from their monomers and polymer. Nice looking products.

How about trying Belarc Advisor??
