Strange address Shown in the dhcp leases

tim.mcmanus

If you have a *NIX box on your network you can run nmap to do some network discovery and determine what is where. I think there's also an nmap package for pfSense that would also scan your network and determine what is running where. Very handy and powerful utility.

what is "NIX box" ??

Know the package which is installed
It does not show anything

Well without 3 different AP and wireless and wired on the same lan without a smart switch.. Yeah going to have a hard time tracking it down.

So your sure its showing up on your lan interface? Or your just seeing it hit your dhcp server? Why don't you sniff for the bootp packets.. This might give you some better clue to what the device in the details of the packet.

And you don't need a nix (unix/linux) box to run nmap, runs on windows just fine. Not sure that would help - the OS identification isn't very good if you ask me.

So can not ping, but it arps?? So when you try and ping that IP, and you look in your arp table you see it?

Destination host unreach normally means it didn't arp..

So no real AP, or smart switch - tracking down something like this can be tricky.. If you had a smart switch and real AP you could see where the mac is listed on physical port and what macs are trying to associate to your AP..

So is your wireless open, or secured.. Change your psk, if can not assoicate with your wireless its not possible for it to get a lease from your dhcp server. If still happens could be one of your routers acting as AP.. Turn 1 off at a time until you don't get it showing up any more.

Do you run any sort of visualization.. How did you check for the mac exactly on all your devices?

i see it on the DHCP leases not in the dhcp server

Why don't you sniff for the bootp packets.. This might give you some better clue to what the device in the details of the packet.

how do i do that ?

no cant see it in the arp

there are all the options

the cisco is real access point

So is your wireless open, or secured

my wireless is secured

If still happens could be one of your routers acting as AP..

my routers are acting as AP as i said

Do you run any sort of visualization.. How did you check for the mac exactly on all your devices?

i went to every computer and tv and printer and lap top
and check (i go to setting Depending on the device And saw the mac address)

diag, packet capture will allow you to sniff.. Pick your lan interface, UDP and either port 67 or 68 since these are the ports bootp/dhcp will be on.

Let it run until you see the lease show up with that weird mac in it, if you have a lot of dhcp on your network then you might need to change the 100 packet limit to 0 or something greater to catch the packets.

Then download it and check it wireshark.

example see attached - you can validate the discover is from the odd ball mac, and then look into the details of the packet and you might get some info that helps you identify what is actually asking for ip.

If you can not see it in arp, your not going to be able to nmap scan it. Turn off your other AP, do you still get it - then look in the AP for associated clients.. If you change your psk, would seem unlikely the device could associate with your wireless and get an IP.. So either its an actual AP device asking for it, or something wired.

So are any of your machines running any visualization software?

What?? No diagnostics on your pfsense menu, packet capture.. You don't need to install any package to do sniffs.

i try it with 67 and 68 port
and the IP of the Weird mac address

and i got Nothing

johnpoz

no I would not put in an IP.. If you delete the lease and it asks for a new one doesn't mean it gets one.. Don't put in an IP..

And how long did you let it run?? Thought you said it could take 16 hour for it to show up?? Did a new lease show up? After you deleted the current one?

firefox

so i need to delete the IP from the DHCP leases

in the packet capture screen i should leave Host Address Empty
in the port Enroll 67

and let it run

Then again, with the number 68 ?

johnpoz

Make sure you put in UDP and either port 67 or 68 would work.. see attached

Yes I would delete the lease, so you know for sure if it shows up again or not, etc.

Depending on how many dhcp clients and how long your default leases are, etc.. You might get some noise.. Which is why should prob set to 0 for how long to capture.. You can check it every few hours stop and download and start it again if you don't see anything in the leases table showing the odd mac…

You have an issue with 192.168.0.3 for sure.. What is the lease time on it? Your seeing dhcp traffic every couple of minutes on him??

firefox

i installed wireshark

but do i use it
how do i take the Result And passes it to wireshark

johnpoz

the download button, then open it in wireshark.. But from what you posted I don't see any dhcp traffic at the time of the lease.

Do you have any D-Link hardware on your network? A Google search of that MAC address shows up regularly in forums discussing exactly the issue you are experiencing. In many cases, there is a D-Link piece of hardware on the network where 0000:00:00:00 shows up.

Wireless access points have two NICs in them (minimum) the wired network and the wireless network. If you do have a D-link device, see if you can determine what the MAC address of each interface is.

also just to cover all the bases on the pfsense via console or ssh to it do a ifconfig –- this will show you all the macs of all the inerfacers on the pfsense box.

i do have a d link router that i use as AP
but it is Connected and working for a year now
And this address appeared week and a half maybe two weeks ago
Also checked the mac address of this router
It is different

Currently the router is disconnected from the network Because of Different reason (Room renovation)

So you have a bridge with your wifi and lan (fxp1) – redo the sniff test but listen on the wifi interface this time.

So if the device was connected to one of you AP on your lan network you should of seen it in the capture. But guess it could of come in with your wlan on pfsense that you have bridged to your lan and not seen it in the capture..

What devices are connected to your pfsense wifi interface?

Totally OT:

Some months ago I had a really bad dream that all the WLAN routers and devices could be connected to one big, global network by a bad, bad 3-letter agency in totalitarian country somewhere in the world…

Just a dream :-)
