To be perfectly honest, I'm not the most technically mionded of people
and I don't know if this is the right group for this so apologies to start with. OK - question tie : On Windows XP (not sure about other O/S's) there is a nice little service called Net Send. This is OK for networks. Is it possible to have something similar over the internet using an IP address instead of a machine ID or username? richardmgreen wrote:

Normally if you want to chat or send messages to people outside your local area network, you use an instant messaging client such as Trillian, AIM, MSN, or Yahoo. Post back with a better description of what you'd like to do - your end goal - to get more focused suggestions. Malke Basically, I want something similar to MSN but without having to sign
up to anything or have to log in every 15-20 minutes. What I want to do is increase that by sending to an IP address rather than a specific user/lan ID, without the necessity of downloading/using external software. I have tried using an IP address on a LAN and it appears to work, but I don't have an IP address available to confirm with a friend working for another company on a different LAN. Any thoughts would be appreciated. richardmgreen wrote:

He will have a private IP address (non-routable and invisible from the Internet) and unless port forwarding has been set up with the appropriate ports opened in the corporate firewall and he has a static private IP, you won't be able to get to him. This is basic and good corporate security. The reason that Net Send works on a LAN is that all the machines are on the same subnet. Since you and your friend work for different companies and are not on a company network connecting various branch offices (WAN - Wide Area Network), you will need to contact him with an instant messaging client. As for logging in "every 15-20 minutes", you have something set up incorrectly. You didn't say how you connect to the Internet, but here are some things to check: 1. If you are using dialup, look at the dialup settings and make sure the connection is set to stay up after a period of inactivity. 2. If you are using broadband and an ethernet adapter and are losing Internet access, make sure the power management on your NIC is disabled. 3. If neither #1 or #2 is applicable, look at whatever instant messaging client you are using for "keep alive" and logon options. Malke TIP: I use Skype and I'm happy with it.
Let me completely discourage you from doing this. There are so many spammers on the internet, that in the very moment you open a way for windows messenger packets to arrive on one computer you will start receiving SPAM messages every minute. Messenger will listen on a port in this range: (UDP: 1026-1032) usually 1026, because my firewall blocks most packets on this port. HISTORY: Recently I wanted to see what traffic my firewall was blocking and why are there most packets arriving on these ports. So I set up a sniffer and waited a few hours. All packets were Messenger messages. And all looked like this sample: [SYSTEM ALERT] STOP! WINDOWS REQUIRES IMMEDIATE ATTENTION. Windows has found CRITICAL SYSTEM ERRORS. To fix the errors please do the following: 1. Download Registry Cleaner from: [http://] address from where you can download a fake program - most likely spyware[.com] 2. Install Registry Cleaner 3. Run Registry Cleaner 4. Reboot your computer FAILURE TO ACT NOW MAY LEAD TO DATA LOSS AND CORRUPTION!

Reboot your computer >FAILURE TO ACT NOW MAY LEAD TO DATA LOSS AND CORRUPTION! I've looked at the Windows Messenger hack traffic a couple times myself. What's interesting is that it's coming from a botnet - computers owned (legally) by other peoples who fell victim to the same sh*te (and now 0wn3d by the bad guys). <http://nitecruzrnews.blogspot.com/2006/08/bots-and-you.html> http://nitecruzrnews.blogspot.com/2006/08/bots-and-you.html -- Cheers, Chuck, MS-MVP [Windows - Networking] http://nitecruzr.blogspot.com/ Paranoia is not a problem, when it's a normal response from experience.

This means that computer-1 does not need to establish a connection to computer-2. No need for valid backward path. So computer-1 may fake it's IP address. And even if the bad guy uses his/her own machine to send malicious UDP messages, this is almost impossible to trace back if the IP address is fake, because the fake source IP means wrong backward path.
