Specific mac addresses?

I have an Airport Extreme base station in an upstairs closet ( with printers, dsl, security system, fire, panel, etc) and I use a couple of Airport Express to bounce the signal around downstairs. The two expresses have solid connections to the base -24 -95 but where it gets strange is getting the laptops and imacs to connect to the closest express. They always seem to link up with the express that is farthest away from them. Is there any way to set the computers to connect to a specific repeater? I can not seem to find a way to specify that a certain radio connect to a specific repeater/ mac address...

Is there any way to set the computers to connect to a specific repeater?
Unfortunately there is not.

How I can lock my Time Capsule on specific MAC addresses?

Ok, you mean MAC filtering..
This is called timed access on the airport utility..
Set no access for all other wireless.
Then add for your own.
Setup all the computers that you want to have access and whatever the time..
You can only MAC filter wireless clients not wired.
Do a search if this is not enough for posts by Bob Timmons on Timed Access.

WRT54GL V 1.1 : how to reserve IP for specific MAC address using DHCP

My !free! made in China router have this functionality. And yet I have been banging my head with this new reasonably expensive wireless router from Linksys. Anyway I lug my notebook around. I need my home router to be able to automatically configure notebook IP address using DHCP. At the same time I need the ip given by home router through DHCP to be the same IP all the time. So "static" ip is not the solution. Alternative "static" ip is also not a solution. Anything with the word "static" in it is not a solution. I know about third party firmware (wrt or tomato) and I know WRT54GL can be flashed with this third party firware. But I'm not going to void my warranty. This will be my last option but not the solution that I seek. I would like to know how to reserve ip for specific mac address using DHCP for WRT54GL V1.1. If this version have no way to make such configuration, I would like to know if there is official firmware upgrade that address this. Thanks in advance!

Force mapping to a specific MAC address a multicast IP address in ARP cache table with netsh

Hi all,
I would like to know if there is any solution (netsh option, registry entry, whatever...) to force mapping a given MAC address to a multicast IP address (224.x.y.z) in my ARP cache table.
I am doing the following:
netsh.exe interface ip add neighbors "Ethernet" "224.224.xxx.yyy"
"00-80-EE-UU-VV-WW"
But the entry in the ARP table is substitued by the calculated multicast MAC@ corresponding to my multicast IP@ :
netsh.exe interface ip show neighbors "Ethernet"
Interface 12 : Ethernet
Internet Address
Physical Address Type
224.0.0.22
01-00-5e-XX-YY-ZZ
static
224.224.yyy.zzz
01-00-5e-UU-VV-WW
static
(For information, calculation of the Multicast MAC Address is described in RFC1112§6.4 -> The MAC@ equals 01-00-5e + the last 23 digits of the multicast MAC Address)
My problem is that I'm not using an Ethernet network but an AFDX (used on Airbus A380, Boeing 787 Dreamliner, by the NASA...). This network topology is a deterministic Ethernet. The network must know accurately where each network packet is going. Thus...
the multicast MAC@ cannot be accepted and packet destinated to that MAC@ are not going anywhere.
So, I must match accurately my multicast IP@ to my MAC@ (00-80...).
It used to work with Windows XP (which was not doing any "magical" MAC@ substitution on multicast IP@), but since Windows Vista, netsh is doing the substitution described above. Is there any way to disable this substitution or force my IP
to MAC mapping in ARP table? And of course, I'm not using XP anymore ;)... but a tablet with Windows 8.1.
Thanks for any help.
Cheers,
Olivier.

Hi,
The article you pointed me to is just an explanation of what I said in my original post : "Multicast MAC Address is described in RFC1112§6.4".
But, as I said in my original post, this is true ONLY for Ethernet network. And I am NOT on an Ethernet network.
So MAC address automatic calculation for my IP address done by Windows/netsh/arp is wrong in my case. The calculation Windows is doing is correct ONLY for Ethernet network. Since I am not on Ethernet, I don't want these calculations, and I'm looking for
a solution to disable them.
So, the underlying question is : "Is Microsoft/netsh/arp able to handle other network's type than Ethernet ?"
Thanks,
Olivier Dupré.

How do I set timed access for specific mac addresses?

My daughter tends to stay up late on social media long after we've asked her to go to bed, so I'd like to use the AirPort Utility to just shut off her internet access during set hours. It looks fairly straightforward to set up, however, I don't know how to find her MAC address for her iPod. Can anyone enlighten me?

iPods, IPhones, and iPads do not have a MAC Address.
On the iPod home screen, tap Settings
Scroll down and tap General
Tap About
Scroll down to locate the Wi-Fi Address
Use the WiFi Address of an iPod, iPhone, or iPad in place of the MAC Address when you are setting up rules in Timed Access.

ISE 1.2 disable endpoints with certain mac address

Hi All,
We have an AD to authenticate for wireless users. In AD, we have specified to block the user if the password is entered wrongly for more than 3 times. The problem is some of them are using other user ID and locking the accounts. I have gotten the MAC address of the user. Can anyone please advise how to block the request from this MAC from even reaching the AD.
Thanks

You have two options from ISE and one option from the WLC:
The first option which is not very scalable is to modify your authentication policy to deny access to an specific MAC address(Radius:Calling station ID). But this is not very scalable as you can only specify one MAC address.
Your second option is to enable the anomalous client suppression(under systems->settings->protocols->RADIUS). This will be your best option but it would require a bit of testing to identify what are the best values for your environment.
From the controller you can enable the excessive 802.1x authentication failures. By default it won't even send the fourth authentication to ISE for a failing endpoint:

Same SSID different MAC address

Ok... This is the best place for me to post this I think...
I am sharing an internet connection and am relatively close to the router (linksys) but because of the materials my building is constructed with I get a **** poor connection. So, there is a closer range extender that I can connect to, the range extender is also a linksys range extender, and I have no problems when I connect to it. The only problem is actually getting connected to it in the first place. My computer will automatically connect to the router rather than the base station. They both have the same SSID, and obviously different MAC addresses. Is there a way to force my computer to only connect to the range extender and ignore the signal from the router?

I have no problems with the range extender itself. It works great. The problem is that my airport card cannot tell the difference between the range extender and the router. Sometimes it will connect to the router, and sometimes to the range extender. I want to force it to connect to a specific MAC address rather than using only the SSID. Is there a way to do this?

SG200-8 Static mac address problem

Hi!
My second problem with sg200-08 (firmware: SG200-08x_FW_1.0.6.2.stk) is when I try to add specific MAC address as secure:
MAC Address Tables - Static Addresses - Add; insert vlan id, port, mac address and select "Secure":
I get error message: "Error: Failed to Add 'Static Address' entry.
Again, thanks for reply!
Best regards,
Boris Bahes.

Strange as it may sound, try playing with compatibility mode in Internet Explorer. I have found that these switches interface respond well only in IE.

Why does my AE gen 2 crash when I put my iPhone MAC address in?

AE gen 2 with Time Capsule.
I use MAC address for security (I think that is OK). I have a number of items that need WIFI and their specific MAC addresses are put into the box. All OK so far! Recently my wife and I have purchased iPhone which I also want to have access to WIFI from AE. In goes WIFI address for both phones and it will not restart after 'UPDATE' command given.
Push the reset button while it is plugged in and it comes back minus the MAC addresses specific to the iPhone!!!!!
Any ideas? Could it need replacing?
I tried going to WPA2 Personal but my wifes laptop kept coming back with "Connection Timed Out".
Have done HARD reset (Reset button with power cord out then insert while keeping reset button pushed) and no difference.
Any help would be very much appreciated.
Thx
David

Both our laptops are MacBook Pros.
Then they both really shouldn't have any issues connecting to a wireless network configured to use WPA2 Personal which uses the AES/CCMP encryption protocol. Currently the strongest security type available for consumer wireless networking.
I was under the impression MAC addresses were pretty secure.
Although MAC addresses are unique, as I have mentioned they can be spoofed. So a wireless client, using a spoofed MAC address, can easily bypass any security method that relies on these addresses. The other security failacy is closing or disabling the broadcast of the wireless network name. This may thwart the most casual network leech, but like MAC addresses, the network name (or SSID) can still be found using utilities easily obtained from the Internet.

WRT610N: Cannot enter MAC address in MAC address filter list

My WRT610N cannot accept a very specific MAC address in any position of the MAC address filter list. It is a valid address and it was working fine in the filter list of my WRT54G but the 610N will just not take that specific address! What is this all about?
Solved!

There is nothing like a "non-critial setup". It's enough to drive by with a car and within a few minutes your network is hacked. Or it's the bored teenager next door...
I recommend to replace the WEP only device instead of taking the risk of a hacked network.
And just forget about the wireless mac address filter. Anyone, who wants to crack your WEP network will collect enough accepted MAC addresses during the cracking process. It's just not worth the trouble to set up the filter and keep the list current...
Thanks for the diligent follow-up gv but I can't replace the WEP-only device for now. (I need to go through a conversion process for that device to accept WAP and that will take a fair amount of time) I understand your point about getting accepted MAC addresses but, at least, it requires a bit more effort... Maybe I will return the WRT610 and stick with my old WRT54 until the 610 gets fixed...

Specifying MAC addresses in a wireless network

In order to keep the neighborhood riffraff from sniping my wireless internet access, I'm setting my wireless router (Linksys WRT54G) to allow only the specific MAC/Ethernet IDs of the wireless computers/iPhones/etc. in my household.
I use Airport Express to extend my wireless network, but I already have it set to the specific MAC address for my router. Do I need to add the Airport's WAN ID to the list as well?

Thanks for the reply! Actually, I already use the 128 Hex WEP password method, yet it still seems like my signal regularly experiences slowdowns at non-peak times. I have to unplug the power from the Linksys router and the cable modem every few days for about a minute or so. Is it possible for someone to snipe the wireless internet access even with the 128 hex WEP? does the router make a distinction between wireless network access (that is, access between all the Macs in my house) and wireless internet access?
You may be right- I may be making things too difficult. Honestly though, I seldom have anyone bring their computers into our house to connect to my wireless network.

Mac Address/IP address

Hello friends.....
this may not be exactly a java question but I know this is the best place to shoot it..........
In our hostel we are not provided by a static ip address which results in changing of ip addresses very frequently now in that case my server's ip changes and I cannot rely on IP addresses alone
I have also heard of MAC addresses which are hardware specifications.....and are specific for each computer on network...now I want such a functionality that even if my ip address changes I may be able to use the specific mac addresses to find out my server , extract its ip and connect to it..
now the simple!!!! part is How to do it <img class="emoticon" src="images/emoticons/mischief.gif" border="0" alt="" /><img class="emoticon" src="images/emoticons/laugh.gif" border="0" alt="" />
any other suggestion is also welcomed.......
Thanks and regard
ad

thanks for the link......
i will find out something.........but i will appreciate it if you can explicit explain the solution....and will wonder if you help me how to implement it via java.....

MAC address blocking

Hi, need help on blocking a specific MAC address on an interface. On that interface it is cascaded to a hub.
Config# mac-address-table permanent aaab.000f.ffef e0/2
- is this the right command and can i list all the MAC address that is allowed to run? or there is a command to just block one MAC address and the rest is ok?
OR
Config# mac-address-table restricted static aaab.000f.ffef e0/2 e0/3
-almost the same as above but more restrictive

Which switch is this ?? What model number and the IOS version.
What I can think of is using 2 ways :
1 Configuring the MAC Acl and applying it to the same port but this block only non-ip traffic.
2. Configure port security and secure you addresses as static and give the number of max-counts the same the as number of amc you want to allow which are connected to hub.

Mac address filter

Is it possible to identify the visitors mac address using PHP
if yes is there anything to prevent you from limiting access to specific mac addresses (say by using an IF statement to redirect other users to a different site)

You can identify the IP address, but that doesn't take you down to the level of the individual machine.

WRT310N - Access restriction not functioning by MAC address

I am trying to block internet access on my kids computer so they can do homework weekday nights.
I have it set to Deny on a specific MAC address (yes, I double checked the MAC ID), for specific hours during the week.
Yet the internet access still exists during these times.

Try with IP address, but most of the times the Access restrictions on the Linksys router doesn't function correctly. Go for some third party software, which can serve your purpose.
