How to find mac address of a client computer in specified time and port in WIFI WCS Control system

how to find mac address of a client computer in specified time and port in WIFI WCS Control system

WCS record-keeping is very crude.
You'll get the time/date when the client authenticated. You'll get the local inside address but you'll need the router to translate the outside IP address and the port.
You will need a proxy server to determine what sites did a wireless client goes.

How to find MAC Address in Java, Windows Environment

Dear All,
How to find the MAC address of a machine, provided the IPAddress of the machine.
Thnx in advance..

Generally you can't. MAC addresses do not travel through routers.
For computers on your local subnet: connect to the computer somehow so that your computer knows the MAC, then run the command "arp -a" with Runtime.exec() and parse the output.
Or write a program/servlet that runs on the remote computer and returns that computer's MAC (or some of the MACs for computers with several network cards.)

How to find MAC address for WAN port for Airport Express 2nd Gen.

The New Airport Express has a LAN and a WAN ethernet ports. How can I find the MAC address for the WAN ethernet port as my Service Provider needs it for provisioning....I can fid MAC address for Ethernet and for two wireless 2.4 & 5GHz but not for WAN ethernet port using Airport Utility 6.1

Many thanks for the swift response. However, there is no WAN MAC address on the box or on the device anywhere. I even used magnifying glass to find one .
The airport utility shows only three mac addresses. One for 2.4GHz, one for 5GHz and one fo the ethernet (LAN port) whereas there is another ethernet port in the device mentioned as WAN port and I am still not able to find the MAC address for the WAN ehternet port for Airport Express (2nd Generation).
Will appreciate a response to make th device work wiht my service provider as providing them the WAN mac address is a must. Had there been an option for cloning mac address, the issue would have not been there.
Many thanks again - in advance.

How to find mac address with 10.7.2 on macbook air

my dorm doesnt have wifi we r required to sumit our mac address in order to connect to use internet with internet cable

Use the System Information. To get to this, go to the Apple menu, select About this Mac, and click the System Report button.
In the left column go to Network and select Wifi. Under interfaces select en1 and look for the MAC address.
Alternatively you can use System Preferences > Network > Wi-Fi > Advanced button > Hardware tab > MAC address.
Best of luck.

How to find MAC-Address of a device using ADF mobile?

Hi,
I am developing an mobile application using ADF Mobile. The application necessitates the use of MAC Address for further development.
Android SDK provides an easy way to find the MAC Address as:
WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo wInfo = wifiManager.getConnectionInfo();
String macAddress = wInfo.getMacAddress();
Is there a similar way in ADF mobile to retrieve the MAC Address of the device?
Regards,

This cant be done.

How to find Machine Id of a Client Machine.

hi
Is there any way to find MAC ID of a Client Side Machine. because IP_ADDRESS is not Satisfying all the Security requirements.
Please Provide me the Solution or if this type of Thead is already exists in the Forum then Pls Provide me the Link.

As Faust said - this is not possible in Oracle PL/SQL (not supported). The only alternative is to write a custom function to obtain the Mac address.
Such a function will need to be in Java or created as an external procedure (a DLL in Windows or Shared Object lib on Unix).
However - even if you code such a function how can it obtain the Mac address? The external process or Java procedure cannot obtain or access the TCP socket handle that Oracle uses for that client session.
If I'm not mistaken, when dealing with a shared server process, it will not even know what the handle is - as the communication part with the client session is handled by the dispatcher processes. Which means (if I'm correct with this assumption) that the shared server session has no TCP socket handle at all to reference.
Let's assume I'm wrong and in both cases the socket handle exists in the Oracle server - how do you get Oracle to pass that to a Java proc or an external proc? There is no variable available in PL/SQL or SQL that allows you access to that session's client socket handle.
I do not see a feasible solution for what you want to do. The best would be to record this at two levels. At firewall level record Mac address, IP address and time - in Oracle record IP address and time - combine these two logs for marrying the one with the other.

How to get Mac Address of Remote Computer

Hi All,
I tried to find out a solution for finding Mac Address of a remote system, then first i tried with finding it with local address using the following code it works fine for me.
public class MacAddressFinder {
     public static void main(String[] args) {
          try
               InetAddress ipAddr = InetAddress.getLocalHost();
               System.out.println("Current IP address : " + ipAddr.getHostAddress());
               NetworkInterface nwIntf;
               try
                    nwIntf = NetworkInterface.getByInetAddress(ipAddr);
                    byte[] hwAddr = nwIntf.getHardwareAddress();
                    System.out.print("Current MAC address : ");
                    StringBuilder sb = new StringBuilder();
                    for (int i = 0; i < hwAddr.length; i++)
                         sb.append(String.format("%02X%s", hwAddr, (i < hwAddr.length - 1) ? "-" : ""));
                    System.out.println(sb);
               } catch (SocketException e) {
                    e.printStackTrace();
          catch (UnknownHostException e) {
               e.printStackTrace();
But when i tried this piece of code in jsp with the following code i am getting NeworkInterface object value as null and there by i am unable to get the Mac Address of a remote computer.
InetAddress ipAddr = InetAddress.getByName(request.getRemoteAddr());
NetworkInterface nwIntf = NetworkInterface.getByInetAddress(ipAddr);Can you please suggest me how to find out the Mac address of remote system?
Thanks,
Uday

first of all, NetworkInterface only exposes the NetworkInterfaces of the local computer. secondly, you cannot find the mac address of an arbitrary remote computer. that information is not available outside of the local subnet. and java doesn't expose a way to discover it even for computers on the local subnet.

How to block mac address in 2800 router

sir
how to block mac addresses in cisco 2800 router

Hi,
To block mac addresses you can simply create Mac based ACLs which ranges between
700 to 799
Example:
access-list 700 deny xxxx.xxxx.xxxx.xxxx
access-list 700 permit yyyy.yyyy.yyyy.yyyy
now you can apply it on interface:
int f0/0
access-group 700 in
exit

How to see mac address in IPS 4240 ???

Hi all,
How to see mac-address of inline-vlan-pair ? and how to see mac-address of management interface in IPS ?
Regards,
Kiran

Hello Kiran,
The inline-vlan-pair itself is tied to a particular interface. So you're really asking for the MAC address of the interface associated with the inline-vlan-pair.
The MAC address of sensing ports will be added to a "show interfaces" via CSCse84414. You can currently view the MAC address of sensing interfaces by doing an "ifconfig -a" from the service account.

How to trace MAC Address Of a Machine with PL/SQL

As MAC Address Of a Machine is Unique, for security, how to use trace the MAC Address of a machine on a WAN/LAN and record it in the database.Please note that it is important part of Audit Trail

MAC ADDRESS is unique, whereas IP Address is variable. Experienced user can very easily change (fake) MAC address.
Maybe you will be surprised it is trivial as changing of IP.
You may be able to build a component that is external to the database that can determine a MACOn linux (for example) you could use "arping" command or retrive MAC adressess from arp cache using "arp" command. arp cache stores MAC adresess of all computers which are or was connected to machine. These commands can run only privileged user (root) but you could give execute privilege for specific user (oracle) via "sudo". You can execute this commands using external procedure or call it from Java stored procedure.
It think tracking of IP will be enough beause IP must be unique on network (or in specific subnet).
So MAC tracking is waste of time (IMHO).

How to change mac address on mac

i'm sry i'm not sure if this is the right section or not but yeah.... nyways does anyone know how to change mac address on a macbook?

If you have not updated your OS you can use the following command.
sudo ifconfig enX ether xx:xx:xx:xx:xx:xx
You will need to replace the X with your network number and the xx:xx:xx:xx:xx:xx with the mac you want to have.
Then run
sudo ifconfig enX down
sudo ifconfig enX up
This change will last till your next reboot.
cheers
NOTE: This is not working in 10.5

How to change mac address on time capsule

Hi there,
How to change mac address on time capsule?

There are routers that allow you to create/clone a mac address to whatever you like. Since many companies use the mac address to 'register' a unit connected to it's system, you usually just have to let them know you've changed your router and they will reset your system to accept connections from the new device.
