find smc bridge IP with its MAC address???

hey i need some help. The only way u can reset this SMC2482w wireless bridge is with a web-utility that has difficulty understandin the latest firmware that i have. anyways...i've sniffed the wireless packets with ethereal and i've used netstumbler...all to come up with the bridge's MAC address...i cannot however find the IP which i need to connect through the web-utility to re-configure it. any suggestions? I've already tried sniffin the packets and goin through them to look for the IP. I thought it would be in the ARP packet for sure but no luck...only the MAC address. I know there has to be SOME way to find the IP with its MAC address...i didnt think it'd be this hard...and it shouldnt. Someone help please.

Are you using any managed switches? Checking out the ARP table on a switch should yield the results you need......

What type of equipment are you using in your network?

Angry IP Scanner can be used for this.

Select MAC address as one of the output fields and then scan the network segment that you know it's on (or your entire range if you are unsure). You can even dump the output to a file and you can write a 3 second perl script to find the matching record.

Hope this helps!

nope...tried the IP scanner...and the equipment i'm using is the smc2482w wireless bridge...and my dell inspiron 8500 laptop with wireless card...and a ethernet hub 10mpbs...i tried the ARP table in the cmd prompt and it just came up with my own IP computer...here is a screenshot.

actually i dunno 'bout the perl script...sure it will work? i'm also runnin xp too...as u can prolly see in the screenshot

this is pretty bogus on SMC's part...u should be able to reset it physically and it goes to a default IP. They have it set up to where u can reset it physically but its only for temporary connectivity problems....i'm thinkin like wep encryption and the filters and stuff. The only way u can reset it to factory default is through the web utility which i cannot use.

Without managed switches, it makes it a little diificult.

It may be a possibility.

nope...didnt work. We have several aironet bridges laying around but i wanna get this working...crap like this bothers me. There's gotta be someway to beat SMC's ignorance.

There is a reset switch on the back of the unit, which will reset the IP to factory deafult 192.168.2.55

alright maestro...dunno if u didnt read the post good enough or what...but as i said earlier thats not the FACTORY reset...that is a reset to correct any TEMPORARY connectivity problems...the factory reset u have to do with a web based utility. Cmon...someone has to know. Anyone smart enough to figure a way to do it? It shouldnt be that hard...anyone know how to figure out an IP with a bridge's MAC address????

cmon...anyone know? i know there r smart enough people to figure this out...if not does anyone even know of a program that finds the IP address of a MAC address???

I'm not familiar with bridges, so I'm going to ask a question first: does the bridge handle the DHCP? If so, then the ip is probably 2.2.2.3 (after looking at the screenshot)

The router comes with a utility which is NOT web based for configuring the AP. http://www.smc.com/drivers_downloads...82W_FWv130.zip

I'd like to point out that I have an SMC router and the switch on the back is indeed for resetting to factory settings, but if you only hit it for a second then it will reboot and forget recent changes, to reset it completely you have to hold the switch for 5+ seconds... just a thought...
They are smart enough to realise that it may not always be possible to log in with an IP hence giving you the ability to restore factory defaults that way. Unless of course there is a console port on it somewhere... is this a home or corporate bridge?

Edit:
So I just read the users manual for your switch, amazingly there's a console port on it so if you can't use the windows utility, which was also mentioned in there, to find the ip via scanning for it then you can plug in directly and just set everything up...

You'll find the troubleshooting section on page 47 of the document

ahh...guys...its a wireless bridge...not a switch or router...its a bridge. its got a ethernet port and antennas...and a reset button. no console adapter (or else i wouldnt be here). thanx for ur help though...i wish ur answer would work...i was lookin for a console port too. :-/

deftones12 :
i'd like to clarify my mind:
- u have a WAP (you own it, right)
- that bridge does not have any consol port (that's wierd, r u sure its 802 compliant)
- u'd like to find out the management IP of the WAP

here come some solutions:
- Brut force: Scan IP addresses range with NMAP. u could start with 192.0.0.0/8 or 10.0.0.0/8
- To find out an arp entry related to the bridge, that's require the WAP to generate an ARP request somewhere.
So the question is when does a bridge generate streams.
BPDUs are layer frames only there is no ARP generation (GARP, GVRP, EAPOL, SPT,...)

To me there is only 2 ways to intercept the IP:
1- there is 802.1x process implemented. When a challenge occur the Radius stream is like a tunnel between the authenticator(WAP) and the authentication Server(RADIUS server). Sniff that and u'll get an WAP IP (be aware that's IP may be filtered to forbid any mgt requests.)

2- A snmp manager had been configured into the WAP, on event it will trap some stuff to the manager. Sniff the network or keep a close eye to the CAM table after event will give u the management IP add.
With that method u assume that a snamp manager had been configured!
The good question is: What kinda event are trapped? Commonly duplicates IP are trapped by bridges. So connect 2 laptops with same IPs and watch.
It didn't work: Try duplicate MAC addresses, to do that u'll need amac address spoofer like dsniff.
If their is no 802.1x running or any SNMP manager keep trying the brut force method!

Does that answer to ur question?

If there is no console port then are you sure it's even that model? And I wasn't claiming it was a router I was just saying that since it's the same company that there's a possibility that reset buttons would act the same.

even though i didnt follow all ur ideas networker it sounds like a good idea lol. So plug 2 laptops into the switch and then plug the bridge into the switch also and configure the 2 laptops to have the same IP? Earlier i tried somethign with the same IP's but the laptops wont let me put same IP's...thats the windows utility though. Should i use a IP spoofer? I'll search for dsniff and try the MAC idea also...thanx for all ur help!!!

deftones12:
an IP spoofer won't work because the switch don't care about IPs, it cares only about layer 2 mac addresses and ARP. So u need to generate 2 ARP with 2 mac addresses but one IP.

To do that u can configure 2 laptops (I don't undertstand how windows can forbid that IP configuration) or use an ARP spoofer like dsniff http://naughty.monkey.org/~dugsong/dsniff/
dsniff works on linux (don't know for M$) and I don't know if its compatible with Wireless interface.

For the 2 laptop matter maybe windows have an alogorythm based on the internal ARP table seeing when an MAC/IP association exist => forbid the IP config.
U can try to disconnect the PC from the network, then flush the arp entry
(for M$ arp -d <IPaddy>) and then configure the duplicate IP(it worth a try).
