Dear Team
How I can restrict Mac address in the denied list ,cannot use ip address.

Hi,
If you want to filter DHCP client by MAC address in order to prevent some device from obtaining IP address. You may enable Deny Filters on DHCP console first, and then New Filter by MAC address. Detailed steps you may reference the link below:
http://technet.microsoft.com/en-us/library/dd759190.aspx
Windows Server 2008 R2 or above system version has this function. Reference:
http://blogs.technet.com/b/teamdhcp/archive/2009/02/26/new-features-in-dhcp-for-windows-server-2008-r2-windows-7.aspx
If there is any misunderstanding about your question, please correct.

Mac User Cannot Use Form Created in Windows Acrobat 9.0 Pro

I have created a form and emailed it to a Mac user. He does not know what version of Acrobat he has or even if he is using a full version of Acrobat or Acrobat Reader (I tried to walk him through to check his version, but he could not find it).
He is using a laptop that is about 5 years old.
Anyway....I created this form in Acrobat 9.0 Pro. It works great for me...when I type in the fields, the text falls perfectly on the lines; the autocalculate works perfectly, and the RESET button works perfectly. When he opens the file, the text shows all below the lines, the autocalculate does not work at all, and neither does the RESET button. He sent it to another person, and they too could not use the form.
I have enabled the PDF so it can be filled out by Reader users and it is not in PDF/A mode, but it still is not working for him. I went to the library where they have a Mac and I was able to open it through Acrobat Reader 9 and again, I was able to fill the form out and it worked perfectly for me.
Would anyone be available (with a Mac) through email so I could send you the file to see if any Acrobat pros might be able to tell me what is wrong with it? I am absolutely frustrated to the points of tears over this. If you do not want to place your email here, I will give you mine so you can email me first ([email protected]); just let me know here that you are emailing me so I know to check email rather than check here.
Thank you!
Laura

He's probably not using either Acrobat or Reader. The Mac comes with a built-in PDF viewer named Preview and it has limited support for PDF forms. It even corrupts them when it saves. It should definitely be avoided. Fortunately Reader is freely available, you just have to get him to install it.

Will it be safe for my Mac if I use bootcamp

A year ago, I bought my very first Mac Mini Intel. I downloaded Parallels Desktop just to experience other versions of Windows right on my Mac. I downloaded Windows 7 on it and such, I also went into fullscreen mode to explore. Then ever since I used Parallels Desktop, bad things started happening to my Mac. I kept getting Kernal Panics every while I start my Mac and my whole Mac would just freeze, so I had to restart it. And it was just horrible. Because of this, I had to take my Mac back to the Apple Store. They did a check of my hard drive via disk partition and said it was bad. So they had to get me a replacement Mac Mini which I'm using right now. Ever since I started using the new Mac, everything was working fine. I didn't install Parallels desktop this time because I knew it would give me that Kernal Panic and cause freezes. So now, I'm thinking about using Boot Camp to install Windows Xp, which I want to use for recording gameplay with Fraps. This is a huge risk for me. If my Mac starts getting Kernal Panics again, then i'm doomed. I only have a month of my warranty left before I have no more support. Even though this may sound like a obvious question, I really want to know if this will be safe and cause any issues for my Mac?

There shouldn't be any problems unless you try to write to your OS X volume from Windows instead of to the Windows volume.
Kernel panics in Parallels means a problem with Parallels, not with a Boot Camp made volume nor even with OS X. Of course you should be using the most recent version of Parallels if you are running Snow Leopard.
Oh, and the link I provided includes some other links including information on which Mac models cannot use XP via Boot Camp.

Cannot determine MAC address of connected Access Point using Access Connections version 5

I recently installed the newst version of Access Connections (version 5) and discovered I am unable to determine the MAC address of the connected access point. The 'Graphical' screen shows the SSID, IP address of client etc - but does not show the MAC address of the access point. The 'Details' screen shows the MAC address of the access points - but the radial button on the left does not indicate the cfurrently associated access point.

Is it the switch where the node is directly connected ?
Is the NIC at node side, working fine ?
Another fact to consider is, a mac will wipe itself out after the MAC-age timeout.

How can i get the time capsule to use my mac's mac address

on some wireless routers you can get the router to use the mac address of a client connected to it instead of it's own.
Can i do that on the time capsule?

Sorry, but no. You cannot change (spoof) the MAC address on any of the AirPort/Time Capsule routers.

Use TCP, UDP, or other to communicate with UUT using MAC address instead of IP address

I want to verify that the Ethernet port on my UUT works.
My plan was to ping the UUT and verify that I got a response. However, the UUTs will come to test with an IP that I cannot use on the network. [Please don't ask me to explain why -- the IT group has their rules, and rules are rules after all . . . ]
I can query the UUT (via the serial port) for it's MAC address. But I cannot find any LabView VIs, or DOS executables which use the MAC address as a parameter to invoke a response from the device.
Does anybody have an idea of how I can verify the UUT Ethernet port without having to divorce myself from the company network and set up my own private network? [Oh and by the way, before somebody suggests it, the IT group won't let me put a 2nd network card in my PC -- rules are rules after all . . . .]

I wouldn't worry too much about the address shown in the Remote Management tab. The ARDAgent process, which is what is listening on his computer for connections from Remote Desktop, binds to all active network interfaces and ultimately that's all that matters. Of out curiosity though, to what IP address does the "unknown-b8-8d-##-##-##-##.home" dns name resolve? Is it the WAN address? I can't imagine it resolves to a private address like a 192.168.
In any event, let's focus back on the network structure. Does the BT router have both a hard wired LAN ethernet port as well as a WiFi radio for LAN connections? My guess is yes. I am also assuming that he does *not* have another router attached to the BT LAN ethernet port like an Airport basestation that is serving the WiFi connections. Typically, the LAN ethernet port is given, via DHCP, a real Internet accessible address but the addresses served via DHCP for wireless clients are private network addresses only. It's seems unlikely to me that the router is automatically forwarding incoming connections to a private network address on the WiFi network. But if he plugs his Mac in to the ethenert LAN port on the BT router then you should be able to connect directly to the address given to it via DHCP because it *should* be a real Internet accessible address.

E4200 v2 - Uses multiple MAC addresses for the same device

This unit seems pretty good at first but on looking at the Web interface I noticed that it was using multiple mac addresses for the same device and showing devices on the lan on the Wireless side and other odd things.
After a week of running it the home server network started to get erratic, it would seem to all point to dns and dhcp issues in the router.
Seems the V1 had the same issues that they did not fix on this.
The Cisco connect software shows 5 devices the Web based utility shows 3??.
Its pretty bad that they charge nearly $200 and cannot be bothered to finish the unit or address the issues that were in V1.

I am afraid I didn't get the clear picture of the issue mentioned in the post. Could you please elaborate a little bit? If you connect a device/computer wired and then later you connect it wirelessly. It is obvious that you would get to see two different MAC addresses for the same device, one for the LAN adaptor and other one for WLAN adaptor. If that is what you are referring to?
Secondly, may I know, what issues did you face with DNS and DHCP in the router? Is it not able to resolve the DNS or something else or DHCP is not sending IP address to the clients?

Using NAR to restrict access by MAC address

Hello All,
We have a solution where home users connect via ATM onto our network. Currenty their radius requests are passed onto Cisco ACS 3.3 and they are authenticated using RSA SecurID Fobs to an ACE server.
I am trying to look at an alternative to using a SecurID fob and restrict the end user's access based on MAC address.
I found this on the online documentation for ACS 3.3
"About Non-IP-based NAR Filters
A non-IP-based NAR filter (that is, a DNIS/CLI-based NAR filter) is a list of permitted or denied "calling"/"point of access" locations that you can use in restricting a AAA client. However, by entering an IP address in place of the CLI you can use the non-IP-based filter even when the AAA client does not use a Cisco IOS release that supports CLI or DNIS. In another exception to entering a CLI, you can enter a MAC address to permit or deny; for example, when you are using a Cisco Aironet AAA client. The format of what you specify in the CLI boxCLI, IP address, or MAC addressmust match the format of what you receive from your AAA client. You can determine this format from your RADIUS Accounting Log."
If I specify a clients MAC in any of the non IP NAR options (CLI, Port, DNIS)access is refused. I am using radius IETF and the only time I can see the MAC in the radius accounting logs is when I turn on the option to log cisco-av-pair. Nothing is being logged under CLI or DNIS, so I don't think I can restrict access based on MAC using a non IP NAR. Has anyone implemented what is referred to in the documentation above? Is it just applicable to cisco Aironet? Any ideas?
Thanks.

A NAR is a definition, which you make in Cisco Secure ACS, of additional conditions that must be met before a user can access the network. Cisco Secure ACS applies these conditions using information from attributes sent by your AAA clients. So it is not device specific.

WLC - How to block a single client MAC address?

Hi Sir,
On a WLC (software version 4.1.185.0), how to block a single client MAC address?
I thought of using the SECURITY -> Disabled Clients. Is it right?
There are currently 250 users connected to the WLC. MAC Filtering is not a scalable solution because as I understand it, we have to specify all the legitimate MAC addresses in the local database.
Thank you.
B.Rgds,
Lim TS

Hi Lim,
As you have discovered, the Mac filtering on the WLC is an Allow (based on Mac address) rather than what you need which is a Deny (based on Mac address). I have not tried this feature but I think you are on the right track in using the Exclusion List (Blacklist) feature. Have a look;
Use SECURITY > AAA > Disabled Client then click New or MONITOR > Clients then click Disable to navigate to this page.
This page allows you to manually Exclusion List (blacklist) a client by MAC address.
Add the MAC Address and an optional Client Description for the client to be disabled.
Note When you enter a client MAC address to be disabled, the Operating System checks that the MAC address is not one of the known Local Net clients ( Local Net Users), Authorized clients ( MAC Filtering), or Local Management users ( Local Management Users) MAC addresses. If the entered MAC address is on one of these three lists, the Operating System does not allow the MAC address to be manually disabled.
Hope this helps! Let us know.

How can i use my ipod mac address to find it?

simply put, i left my ipod at work. they missplaced it, now i need to locate it... p.s. its only a 3rd gen 32 gig so its not ios 7 campatible ,icloud only works if you have the device and download cloud on to it(and icloud is turned on).....not looking for opinions just looking for options such as: how can i use my ipod mac address to find it? i do have the mac address

You cannot.
If you did not set up find my pod on the iPod itself, then it cannot be tracked.
Sorry

I just got my Mac and I used my family Apple ID. It had all of my parent's information, I added my e-mail.I wanted to make my own Apple ID, but I couldn't use the same e-mail address again! How do I delete this information so I can make my own Apple ID?

It is not clear how or where you "added" your email, but you cannot create an Apple ID using an email address that is already associated with another Apple ID.
If that is what you did, delete that email address from your family's Apple ID. You should be free to create a new one.
Do all that by starting here: https://appleid.apple.com/
Select "Manage your Apple ID". Log in with your family's Apple ID and then delete your own email address wherever it appears.
Save Changes, log out, and create the new one using the same website. This time select "Create an Apple ID".
Please don't forget your security questions, and be sure to specify a "rescue email address" that is separate from all other Apple IDs. You will avoid so many problems that way...

Router cannot see Hyper-V Guest MAC address

Greeting,
I have been trying to build a server on Hyper-V, on a host running Windows Server 2012 R2, and a wireless adapter is used.
A virtual switch was created as external, connected to the host's wireless adapter.
The guest OS is Debian 7, and the problem is it's unable to use DHCP to connect to the internet.
I have to manually specific an IP address and the subnet mask in order to access the internet in the Guest OS, say 192.168.0.50. And I set port forward to this IP for external connection to the guest, but then sometimes I cannot connect; without doing anything
it restores the connection after a while. At the same time I am keeping the MSRDP connection to tthe host so the host has not lost connecting to the internet.
When the server on Guest is not accessible from the web, I can still connect to the server within the host machine by typing the lan IP of the guest: 192.168.0.50
On checking the router, I found that two IP address 192.168.0.50 (Guest OS) and 192.168.0.15 (Host) are sharing the same MAC address (of the wireless card). It means the MAC address of the Guest OS is not seen by the router, and I suppose this is the root
for the instability.
Would you have any ideas about the situation, and suggested solution?
Thank you.

An update to my issue:
Just realized the possible cause: the (freaking) router is dropping inactive machine.
Basically the DHCP issue is not solved, but it doesn't seem to be a cause after all, as long as I manually assign the IP it works, even having the 2 IPs with the same MAC on the ARP table on router. (Host connection drop has to be further investigated).
As I found that the loss of connection actually happens after a while I don't touch the web server on VM, the longer I leave it idle the more likely I cannot connect to it again. The situation is like a prolonged loading when trying to access a website,
where sometimes you can connect after a while, or you never.
What's weird is, if I somehow manage to connect to the idle VM server by multiple attempts, and that after I have restored the connection, I can reconnect to the server from another computer very quickly without any significant loading time.
On some quick searches, I found someone using Linksys router is suffering from a similar situation as I do:
http://serverfault.com/questions/522448/application-request-routing-on-a-hyper-v-guest-intermittently-stops
So what I can try are basically 3 ways
-Change the router, not viable as I don't own it.
-Insert a wireless bridge in between
-Do something with Debian, making it periodically generate network request to the internet to keep the connection alive
Any ideas about my observation, and maybe possible solutions?
Thank you for reading.

The first problem windows 7-8.1 got IP adress and connect he public HotSpot but cannot load login page or any other page. It does not work with it.
The second problem Wifi canrd/configure/Advandes (No network adress change function).Tested with the default windows driver and the ralink rt 3070 driver the same problem.On windows XP the same function the same driver works perfectly.
multiple users to have expressed interest in the problem But Microsoft not corrected the problem window7-8.1 10?

On windows XP or linux have a MAC adress Change function allow 00 mac adress and another normal mac adress range.On windows 8.1 all Mac changer program dont work.This 2,6,A,E on second adress are not vaild Mac adress. You simply can not use normal MAC
addresses on windows 8.1.When i connect the usb the Pc windows 8.1 recognizes the adapter but the default driver and the downloaded ralink driver the same problem.On windows xp the current driver works perfectly have (Local Mac Network Adress) funktion
and works with the 802.11b hot spot.I got the internet my PC and laptop too public HotSpots and another wifi HotSpots if wont work correctly i can not use neither the windows 7,8,8.1 or 10. Many users have expressed interest in the problem more forums.
The 3. problem im tested in virtualbox the windows 7 and 8.1 on 8.1 (on the blue wifi platform) not show correctly the signal strengh. On windows 7 show this correctly.The windows 7-8.1 Configure/advanced the advanced options on Ralink 3070 the default (windows
driver) somehow downgraded function is less than for Xp. Configure/advanced the advanced options (needs to be upgraded in the future) because it does not advance but rather regressed.
Today it is very common these wi-fi technology increasingly used (hotels,Public Hots Spots,Internet coffe,) growing free bublic wifi projects. The wifi funktions on windows need debugging and modernize.The quality of Wi-Fi is now the operating system
is now a thing order which is not good then the operating system is unusable.

Hi,
For changing the MAC address for Windows 7 is designed with some limitation, we cannot get over it. Thanks for your understanding.
Under Windows 7, the possible range of spoofed addresses for wireless adapters that can be set is limited. To be used by Windows 7, a spoofed MAC address should have 0 as a least significant bit (unicast) and 1 as a second least significant
bit (locally administered) in the second nibble. Thus possible values for the second nibble are limited to 2, 6, A and E.
In other words
MAC address: “XY-XX-XX-XX-XX-XX” “X” can be anything hexadecimal. The hexadecimal “Y”, written in binary format, is Y: “kmnp”, where “p” is the least significant bit;
p=0 --> unicast;
p=1 --> multicast;
n=0 --> globally assigned MAC;
n=1 --> locally administered;
So, actually MAC can be changed to any combination in which p=0 and n=1;
“Y” can be 2, 6, A or E.
So the possible MAC addresses in Windows 7 for wireless adapters:
X2-XX-XX-XX-XX-XX
X6-XX-XX-XX-XX-XX
XA-XX-XX-XX-XX-XX
XE-XX-XX-XX-XX-XX
For the wifi hotspot issue, please check this blog to see if it can be helpful.

Many warnings : prevented from using mac address because it is pinned to port

Hi
I am seeing my system log flooded (several per second) with event 28 warnings such as :
Port 'SWITCHPORT-SM-DB9DCFC7-E98D-438C-8998-CC0D9C14ED2B-1-1' was prevented from using MAC address '00-15-5D-00-B2-05' because it is pinned to port 'A0724966-695B-4552-B'.
Source : VMSMP
The environment is 2 X hyper-v 2008 r2 hosts. both have 4 NICs, 3 nics are connected to virtual switches and management OS is not allowed to share the network adapter, and then 1 NIC is obviously used by the host/mgmt OS and no virtual switch connected to
it. I am seeing the warnings on both hosts.
No load balancing or NIC teaming.
All VM's have their MAC addresses assigned dynamically and I cannot see any conflicting MAC addresses.
The warnings are logged for all or most of the MAC addresses and alternate between different "SWITCHPORT-SM-etc,etc" names.
Performance doesn't seem to be degraded, I've run continuous pings for more than an hour with no packet loss, just a single packet spike every now and then. Network access seems fine, Backup Exec 2012 jobs are succeeding, albeit somewhat slower than what
it was.
I don't know when it started, since these warnings have flooded out all else.
At first I thought it had something to do with a VM that I moved from one host to the other, where I copied the VHD accross and then created a new VM and assigned the original IP address to the new virtual NIC in the new VM. I then uninstalled the old hidden
NIC and restarted the VM in question, but that didn't stop the warnings.
Any ideas what could be causing this, or any tips on where I should start looking to isolate the cause ?

Got it fixed by creating new virtual switches, moving all VMs over to them, and afterwards deleting all the old virtual switches.
Still no idea what the cause could have been. How bizarre...

MAC address of DB or Client machine

Dear,
Can U please tell me how to get MAC address of Database or Client Machine via PL/SQL or routine used in PL/SQL envoirment.
Thanks
FAHAD AZIZ KHAN

To get the MAC the simplest way would be to issue a HOST or CLIENT_HOST command to run ipconfig /all, redirecting the result of that to a file and then use the relevant TEXT_IO to read the output and pull out the Physical Address line.
You'll just have to be careful on machines with multiple adaptors or virtual adaptors (such as VPN drivers) to pick the right one.
