#5125 — Network devices

I have a vague recollection there's a RISC OS command line that will list
all the devices on the local network, maybe arp -something.

I really can't remember... Can anyone please refresh my ailing memory?

Thanks
Dave

arp -a will indeed do some of what you'd like, but I don't think there
is a command to list everything.

arp -a lists all those it is aware of, which really means those it has
been in connection with recently.

Try it, then ping your broadcast address, then try arp -a again, and I
think you'll see some of what I mean.

Ah yes well...

Aside from the router, I have two other LAN things (Printers) active.

In a Command window (StrongEd) if I do arp -a I get...

*arp -a
route-sysctl-estimate

Whatever that might mean.

Aha! I've just remembered something (Expletive) I must away and test...

My remembering was correct, On a Real hardware SARPC, Arp -a etc works
okay, but on a Virtual Acorn it doesn't, and IIRC never has.

Thanks for the thought and prompt.

Botheration! in buckets...

Correct it will not work on VRPC as all the networking is provided by the 
Windows side and passed through to the VRPC program side (Remember as far 
as Windows is concerned its just another application)

Try it instead on the windows side in a command window, I think it should 
work (not got my PC on to double check at moment)

On the Windows side I use a great little programme from NirSoft.

It's called Wireless Network Watcher.

The name is a bit of  misnomer because it shows anything connected via
your router; not just wireless connections but cabled ones as well.

It shows IP address, device name, MAC address, when detected etc.

https://www.nirsoft.net

Go to list on left, choose Network Tools and scroll down the list of
software.
The download link is quite a way down the page after the list of versions
and other bumf.

I've just updated to version 2.40. On Windows 11 defender flagged it up
as a low potential risk but it's perfectly safe so I allowed it. It was
recommended by Computer Active magazine.

Thanks for the info Chris,
As I wrote to the other Chris, I have no problem Win side with the arp
+flags command.

The problem is specifically a possible RISC OS one.

Win side I have a couple of Network scanners installed, the one I use
mostly is "AdvancedIPScanner."

Later I will give the NirSoft app you mention a go...

Thanks
Dave

Thanks, just what I needed but the full version with uninstall etc.
(wnetwatcher_setup.TO1tBEvp.exe.part) is blocked by AVG which says it
has a malware virus. I've never seen a .part file before.

I take it, it's the smaller package  (wnetwatcher.zip)  people are
using? I hope that's safe.

I did try that after Chris posted, but soon consigned it to the bin as I
prefer the one I'm using... :-)

"Advanced-IP-Scanner."  https://www.advanced-ip-scanner.com/

Each to their own of course. :-)

Hmmm.

The Nirsoft version handles ipv6 and allows the user to add notes
about each device. However, the Advanced -IP-Scanner reads the device
names much better IMHO.

I have a fair number of raspberry pi devices and nirsoft capitalises
the device names for some reason and if it thinks the name is too
long it doesn't display it at all.

Good tip - thanks! It shows all the ip addresses as expected and after
a delay ones I don't expect (active ones like 192.168.1.159 and 179).
Are they likely to be scam devices attempting to connect to my PC?

Are they connected via WiFi or Ethernet?
What is their Device name?
Who made their Network adapter?
When was it detected first and last?
What is detection count?
Does your router give any more clues what they are?

I doubt it, as the 192.168.x.x range is local to your network not external 
network.

Could they be other wireless devices, like Smart meter IHD (In Home 
Displays) or even Wireless enabled Alarm systems. or even other smart 
devices you have.

You could identoify the device by the mac address.

Thanks Chris. Using the wireless modem router which I haven't used for
over a year or two I managed to verify the unknown IP addresses.

You are absolutely correct: 2 of them are related to login IP
addresses for routers. The one that had me baffled is Wistron Neweb
Corp. which I searched and is a legitimate IP address for a Taiwanese
company that manufacturers wifi modules, one of which most likely
resides in my Technicolour Router.

Conclusion - nothing suspicious.

But *anything* connected to your local network will get a local IP. They're
far more likely to be things that you own than otherwise, but if they're
connected via WiFi it's certainly worth checking your security settings and
confirming that you do, indeed, own them.

Our smartphones show up when they are on. Can be any device which uses
your network.

Thanks for the thoughts Chris.

I have no problem with the arp +flags command windows side, but this
"thing" I'm trying to sort for a friend is specifically a RISC OS thing.

Yes, the friend has recently updated his Windows 10 to Windows 11 and for
some reason, though his VRPC is working okay, his Printer RISC OS side
which did work okay on Win 10, now doesn't seem to be communicating LAN
wise to the Windows attached printer.

From the RISC OS side I wanted him to Ping the Printer to see if there was
any communication at all, but unfortunately he doesn't know the ip address
of the printer, thus the 'arp' question.

ATM. We are in a holding time as he's very busy with something else, but
when his busy is done, I'll chat to him about how to finding the IP
address of the printer Win side.

TBH. As I know nothing about Win 11, I'm kind of peeing in the wind to see
what returns.  ;-)

Is the printer IP address listed on his router.

It could also be a Windows firewall issue. Also check if the printer is 
still correctly configured on the Windows 11 side.

Both my printers will tell me directly their i.p. address. 

With my Epson WF-7715:
Settings>Printer Status/Print>Network>wired lan/Wi-Fi status
Via the front LCD panel

With my Dell 2330dn:
Menu>Reports>Network setup
And it prints a page of all network parameters and details

Perhaps your friends printer will also freely divulge its details if
interrogated
