How can I track outgoing ip connections?

Question

So I want to find out the port and ip this Java program is connecting to. Does anyone have any resources?
Shoot for best answer ^_^

Hello,



I assume you are under windows.



With doc command you cand have :



1. jps (in your JDK\bin directory)

It shows all the java processe (look jps -h for options)



When you have the process number you want to check, do :

2. netstat -o

It shows all the outgoing connection (and also the listening) and with which IP it is connected.



This is very basic tools on Windows (jps is jdk part, so available with the same options on linux) and i think netstat have equivalent in linux too (and tcpdump is a good one also)



If you have the source code of your java application and can apply a proxy, you can try webscarab (open source proxy) which will trace everything you configure to use it.



A good network analyser/sniffer is wireshark, but you will sniff all your network and you will have to learn the filtering rules to prevent too much information.



Hope it helps

Just follow the steps to track IP



Step 1

Open a command prompt, as many of the steps to trace an IP will require you to have a Windows command prompt open. To access a Windows command prompt, click on Start -> Run. Enter "cmd" into the text field of the dialogue box that appears and click "OK." A black window with a flashing cursor should appear.



Step 2

Find the IP address, which is usually hidden behind a hostname. This hostname (eHow.com, for example) will "resolve" to an IP address through the DNS (Domain Name Service) system. To find the IP address, you can use the "nslookup" command. Enter "nslookup" followed by the hostname you wish to resolve and hit "Enter."

""nslookup example.com""



Step 3

See which name was actually resolved with DNS. There will be a number of lines in the output of the nslookup command. Of interest are the "Name" and "Addresses" lines. The Name line tells you which name was really resolved with DNS. This may or may not be the same as the name you entered on the command line because some names are aliases.



Step 4

In the Addresses line of the output will be one or more addresses. Be aware that a single nslookup can return more than one address and multiple calls to nslookup may return different IP addresses. This is because some DNS names take IP addresses from a random pool of addresses. Most of the time--especially with web servers-- these addresses are all computers in the same building doing the same thing, so it doesn't matter which one you choose to trace.



Step 5

Run a traceroute on the IP address. To see each and every hop a packet takes to go from your computer to the IP (or vice versa), run a traceroute with the "tracert" command. This will take some time, depending on the speed of your Internet connection and the number of hops between you and the IP address.

""tracert 12.34.56.78""



Step 6

Examine the results. You will see a number of lines appear with five columns. The first is the hop number, 1 being the first hop taken outside your computer (which is often your home broadband router) and the last being the IP address you traced. The next three are the result of three ping attempts. You will either see a time (such as 10 ms) or a "*," meaning no response was returned. The final column is the hostname or IP address of that hop.



Step 7

Look for potential problems. Any hops with abnormally long response times may be the source of a slowdown you're experiencing when connecting to the IP address. If the problem does not resolve itself with time, contact your Internet service provider--if the problem is in your network-- or the webmaster or network administrator of the IP address to which you're trying to connect if the problem originates in the other network.

The absolutely free reverse email lookup sites generally provide false information, they just want your email to send you spam. To get real information, money will have to be paid.



Also, stay away from shady reverse email lookup sites, most likely you won't get any information after you make the payment. Not to mention you won't get a report and you won't get an answer if you try to call for a refund. Stick with a reputable reverse phone lookup site like http://www.emailtracer.org that has been around since 1997.

Follow the procedure to track outgoing ip connections



1.Find the IP number you wish to check. The format of an IP address is numeric, written as four numbers separated by periods. Each number can be zero to 255.



---> To find the IP of an e-mail sent to you, investigate the message's "headers" by using your e-mail program's "details" or "properties" function. For example, in Outlook Express, select "Properties" from the "File" Menu, or just press ALT+Enter. Next, select the "Details" tab. In Yahoo, click "Full headers" on the upper right hand corner while you see the message. In Hotmail, go to "Mail Display Settings" and set "Message Headers" to "Full" or "Advanced". See this website for more information on viewing headers.



2.Go to a website that will allow you to look up IP address information. See External Links below. Type the IP number in the input box and submit.



3.Understand that in many situations you will learn a few things about the IP address:

---> Which internet service provider (ISP) the user is using. In some cases this may be the user's company (e.g. Ford.com). In other cases it may be just one of the large ISPs such as ATT or Comcast.

---> The approximate physical location of the user (e.g. Palo Alto, California.)



4.Recognize that usually you will not learn the actual name of the person doing at that IP address (e.g. Joe Smith). ISPs will typically only release such information under a court order.

reverse phone number search compiles hundreds of millions of phone book records to help locate the owner's name, location, time zone, email and other public information.



Use a reverse phone lookup to:

Get the identity of an unknown caller.

Identify an area code.

Recall the name of a person whose number you wrote down.

Identify an unfamiliar phone number that shows up on your bill.
