How to find IP address of local machine

I need to find the IP address of the local machine. I used the following code:
import java.net.*;
class test7
public static void main(String args[])throws Exception
InetAddress add=InetAddress.getLocalHost();
System.out.println(add);
}The output is:
home/117.254.104.194
But i need only the IP address without the name of my local machine. How to acheive it? I also need to convert IP address into either String, Byte, Double, Float or Int. Thanks in advance.

If only there were something in the API docs in this direction!
public byte[] getAddress()
Returns the raw IP address of this InetAddress object.
The result is in network byte order: the highest order byte of the address is in getAddress()[0].

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 do you get values of local machine running applet on remote server?

Hi,
I have an applet that runs great running the html file on my local machine from a root directory. I've placed my code(java, class, and html files) on the web server and loaded the applet onto a page. The results are merely:
"Computer Name: localhost"
"IP Address : 127.0.0.1"
Instead of:
"Computer Name: ACTUALNAME"
"IP Address : 189.40.20.211"
etc...
The code is as follows:
import java.applet.*;
import java.awt.*;
import java.net.InetAddress;
public class IPFinder extends Applet {
public void paint(Graphics g) {
super.paint(g);
try {
InetAddress localaddr = InetAddress.getLocalHost () ;
g.drawString("Computer Name: " + localaddr.getHostName (), 2, 13);
g.drawString("IP Address : "+localaddr.getHostAddress (), 3, 25);
g.drawString("", 3, 45);
String str = localaddr.getHostName();
InetAddress[] localaddrs = InetAddress.getAllByName ( str ) ;
for ( int i=0 ; i<localaddrs.length ; i++ )
if ( ! localaddrs[ i ].equals( localaddr ) )
// g.drawString("Local hostname : " + localaddrs[ i].getHostName () , 3, (i+0)+50);
g.drawString("Local IP Address("+i+"): " + localaddrs[ i].getHostAddress () , 3, (12*i)+((i+10)+45));
}} } catch (Exception e) {
g.drawString("Can't detect localhost : " + e +". Check Network settings.", 3, 60);
public static void main(String[] args) { new IPFinder(); }
I'm trying to get Real IP Addresses (as the code was setup to do) from a browser running on the web server. I have read some of the threads in this forum and some mention to use NetworkInterface while others recommended using Sockets (not an option since we do not use them), and another to use a signature as a workaround. Anyone know the best direction to get the results expected?
Thanks in advance,
Geoff-

I have an applet that runs great running the html file
on my local machine from a root directory. I've
placed my code(java, class, and html files) on the web
server and loaded the applet onto a page. The results
are merely:
"Computer Name: localhost"
"IP Address : 127.0.0.1"This indicates that your applet when run over a web
server has not the rights to query the local name and
address. Look [url
http://java.sun.com/j2se/1.4.2/docs/api/java/net/InetAd
ress.html#getLocalHost()]here. The so-called
loopback address is 127.0.0.1
Check your documentation for "signed jar" (or search
the forum or the sun website) if you want to give your
applet more rights, but I don't think that this is
worth the effort in this case.
gdsimz, since you already started two new threads based on my suggestion, how about at least saying "thank you" or "sorry, didn't help"?

How to get MAC address from client machine ?

Hi dear,
We are implementing security measures for a banking system, so it is required that we track the MAC address of the registered clients along with other parameters. How do we get the MAC address from client machine using ADF or running scripts in client side?
thanks all

Hi,
Welcome to OTN.
Your question has nothing to do with ADF as such. Googling would give you plenty of such topics.

How to find out when was local administrators group changed

Hi
Is there any way how to find out when was user added to local administrators group on server(2003 to 2012) ?

Hi,
If you have auditing enabled for "Audit account management" and your security logs are not overwritten then you can look for a 4732 or 636 (Windows 2003) event ids.

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).

JavaMail Question: How to find IP address of email sender?

Hi,
I currently have a program that fetches email from a pop3 server and processes the email text.
I want to filter out emails to process based on IP address of the sender.
Can you please tell me whether it is possible to obtain the IP address of the sender using JavaMail?
If yes, how? If not, what else can I use?
Thanks,
nitrousFiz

I have checked the RECEIVED headers closely. It seems that the last IP is of my mail server, not my machine from which the email was sent. Excellent. You have done the experiment. Now you know what IP addresses you can get.
Is there a way to get the sender's machine IP or do I have to settle for the email server IP?So you did the experiment. You have the results. They already told you the answer to that.
Here's what you need: an understanding of e-mail's architecture. As you already know, it's the servers that send the messages around the Internet. The servers have their own ways of deciding whether to trust an e-mail client. They may use authentication or lists of approved relayers or something else, or they may blindly trust everyone, but it's up to the initial server to decide whether to trust a client.
It is NOT up to the receiving server to decide whether to trust a client of another server. That's not its business. The receiving server only has the option of deciding whether to trust other servers. In particular your desire to process e-mails from specific locations only is in conflict with the basic architecture of e-mail.
So, I don't know where that requirement came from but if it's really aimed at the client who is sending the e-mail then you can't do that. It would be best to go back and find out why you have that requirement and how that can be implemented within the existing e-mail architecture.

How to synch edited files on local machine to mobile me?

Hi,
I am trying to edit html on an iweb site and I have figured out (by reading here) how to edit the files by publishing the site to a local folder in my machine however, I don't know how to upload those changes to the mobile me. When I change the publish location on Iweb, it just reverts back to the one without my changes. Not sure if this is clear enough but if somebody has modified their html and was able to synch it to mobile me, please help me out. Thanks.

Why publish to a folder on the Desktop when you can open (rather slow) the same files on iDisk.
Mount iDisk (Command-Shift-I) and navigate to :
iDisk > Web > Sites > Sitenamefolder.
And you can use [Cyberduck|http://cyberduck.ch> the same way (It's faster). Connect to MobileMe and open the folder with the file you want to edit.
Right-click the name and choose *Open with*.
I use Smultron for that purpose. It's the easiest app to use for editing HTML :
http://smultron.sourceforge.net/
And if you still want to sync, Cyberduck does it for you.
http://trac.cyberduck.ch/wiki/help/en/howto/sync
Practice with files and folder you can spare.

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.
