lol there are many ways. for example make on ur pc nc listen on port 1333. then on the remote pc type start telnet [ur ip] 1333. then it will connect to ur nc and u will see incoming connection from bla. (bla = external ip ;) )

A somewhat "ghetto" method (although it is quite effective) is to use wget or a similar tool to download http://www.whatismyip.com's index html file which will contain the current IP of the box. Then use BLAT (to email it to you) or a parser of some sort to send the information to you.

telnetting yourself is good but I have some better ideas;

First if you in there you can see remote IP in your netstat check it out;

netstat -an

Also you can telnet a website in commandline;


c:/telnet 67.15.74.5 80


and paste

GET /simple/ HTTP/1.0

Don't forget double enter at the end

setthesun me = new setthesun();

If victim is behind a router you can just get internal IP, MxMx asking this for this reason

setthesun me = new setthesun();

Netstat should work fine but why the "GET /simple/ HTTP/1.0"?

As I said it's just another method "/simple/" is directory name.

Also I attached a small tool before for determining external IP, you can use it for your or a remote computer.

Hey. I know this is an old subject, but if anybody is running unix:

#!/bin/sh
#
# Script for getting an external WAN IP
#

URLS[0]="http://checkip.dyndns.org"
URLS[1]="http://whatismyip.com" 
URLS[2]="http://www.whatismyipaddress.com"
URLS[3]="http://ipid.shat.net"
URLS[4]="http://www.edpsciences.com/htbin/ipaddress"
URLS[5]="http://www.showmyip.com"

for URL in ${URLS[@]}
do
        THIS=${URL}
        IP=`curl -s "${THIS}" | tr -cs '[0-9\.]' '\012' \
                | awk -F'.' 'NF==4 && $1>0 && $1<256 && $2<256 && $3<256 && $4<256 && !/\.\./' | uniq`
        if [ $? == 0 ]; then
                IP=`echo $IP | awk '{print $1}'`
                echo "Your WAN IP Address is: $IP"
                exit
        fi
done

ok here's small program to retrieve the ip from http://checkip.dyndns.org/ and the source coded in c


wanip.c
#include <wininet.h>
#include <stdio.h> 

#define AUTHOR "da_cash"
CHAR buffer[100];
int i=75;

int main()
{

printf("+-----------------------+\n");
printf("+ WAN IP by %s/2k5 +\n",AUTHOR);
printf("+-----------------------+\n\n");

HINTERNET hINet, hFile;
CHAR buffer[100];


hINet = InternetOpen(AUTHOR, INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0 );

if ( !hINet )
{

	printf("Error getting WAN IP");
return;
}


hFile = InternetOpenUrl( hINet,"http://checkip.dyndns.org/" , NULL, 0, 0, 0 );


if ( hFile )
{

DWORD dwRead;
InternetReadFile( hFile, buffer, 100, &dwRead );
} 
InternetCloseHandle( hFile );

InternetCloseHandle( hINet );
printf("WAN IP:");


	while ((buffer[i] != 0x3C) && (i < sizeof(buffer)))
	{
  printf("%c",buffer[i]);
  i++;
	}

printf("\n");

return;
}


include wininet.lib


code may be unproffessional but it works..i'm still learning. binary version attached.

Why are all of u thinking so difficult ? Just set a nc listner "nc -vvlp urport" and telnet to urself, and that way u see what IP is connecting. And even if that is too much work u can als just type netstat -a what connections u all have.
