Active wired clients?

Hello everyone.
There are several computers connected to my router by L2 switch, I want to see who is online.
I cannot just look at the LED because they will always stay on because the switch is on, and several clients may on the same interface…
DHCP server / leases helps a little but it’s not real time, a client won’t disappear after it disconnects.
I used to use wireless tables / registration for wireless that work perfect, but what can I use for wired connections?
Thank you!

See the torch.

Thank you, but that tool seems more like firewall / connections, not clients, and it need to “run” and admin access.

what is the problem? you can use the torch to see what traffic goes where…
You can also use queues by clients address.
Or you can use some NMS, like mikrotik Dude and check the running clients by ping.
You can use netwatch to check the clients by ping also.
You can shorten the lease time of dhcp server to see the more actual status of dhcp leases.

depends on you what exactly you need.

I just want a easy-to-see list similar to wireless tables / registration,but for wired.
Is it impossible? Since wired connections don’t “keep-alive” periodly like wireless?
Thank you.

I have provided many options to you. Try them.

Thank you. I’m using DHCP last seen time to see which client active at what when…
It’s not that real-time, but it’s the best I can find to run with read a only access.

I dont think that last seen is reliable value. At least not for me:

The 50thousand days is definitely not correct value…

WOW, that’s a bug for you…
My last seen time is much more reliable, but it depends on client type, windows 7 clients will renew every several minutes, but XP barely renew…

I see this on many of my dhcp servers, using ros 6.29. Not sure if it was before, but I think so.
