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 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 get MAC address using java code
hi friends
please write me, How can I get MAC Address of local machine using java code.I don't want to use JNI.
Please reply me. Its urgent for me
Thanks in advance
USYou have several ways under *nix
ifconfig -a | grep HWwill output something like
eth0 Lien encap:Ethernet HWaddr 00:11:FF:74:FF:B4combined with Runtime.getRuntime().exec("")and Process.getInputStream()you should be able to read it easilly.
Under Windows (and Linux of course) try jpcap (http://sourceforge.net/projects/jpcap)
You can also use jnative as a generic tool (http://sourceforge.net/projects/jnative)

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 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,
JosephThis cant be done.

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,
Udayfirst 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.

We have a client who is still using Oracle 8.0.6 on NT 4.0
I have a laptop with oracle client 10g.
I want to connect to the NT database to check it.
How do I know what port does the listener used ? what is the command to run at the c:\ command prompt?
I tried> c:\ lsnrctl stat but the command is not recognized
I tried to find the lsnrctl and bin but there is not.

How to find the listener port on windows?The Internet Protocol stack comes with a number of utilities - one of these, called netstat, is very useful to determine which processes are doing what to which IP ports on that platform. Unfortunately, different flavours are implemented. So the Windows one does not support the parameters and output than the Unix/Linux one.
You can use the following on Windows (run it via a command console) to see what processes are listening on what address and port number:
c:\> netstat -n -a -p tcp
-n = display IP addresses and ports in numeric format
-a = list all ports (including ones used for listening
-p tcp = only display protocol entries for TCP An Oracle listener entry should look something as follows:
Proto Local Address Foreign Address State
TCP 0.0.0.0:1521 0.0.0.0:0 LISTENINGSeeing IP +0.0.0.0+ means that the Listener is accepting connections on all your network interfaces - which is standard. The port number is typically 1521. The foreign address is meaningless for a port in listening state.
PS. Why not simply check the listener.ora configuration file? Because what is actually happening may not be what you thought you configured to happen.. -

How to block mac address in 2800 router
sir
how to block mac addresses in cisco 2800 routerHi,
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,
KiranHello 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.
Thank you,
