How can i send a message to my friends computer

Hey thanks alot for your help. And I totally understand the concerns some of you have about the whole social engineering thing so, sorry if any post sounded like I was being an ass. ;)

Basic 'net send' probably doesn't work because a lot of ISP's now block ports 135, 137-139, and occasionally 445. There is however another way around. For Windows 2000 and later, net send attempts to make it's connection on port 135 by default. If however, the ISP is blocking that port, there is another way. The messenger also listens on an ephemeral port (1024 or higher). Why Microsoft chose to do it that way, I'll never know. But if you can figure which port messenger is listening on (usually 1024-1028 or in that general area) and send the message to that port, it gets through just fine and messenger pops up just as if port 135 were wide open. The scum who use messenger to send spam started figuring this out, as I occasioanlly see messenger traffic to these ports on my cable modem connection. So the answer is, yes, it can be done, but since I'm not a big fan of the service, I'll leave it to you to figure out how. :)

Alright thanks alot for the hhelp

By the way here is how you can do it but both you and him would open up the messenger service on your computers that would also put you out there to get spam messages from other people and a lot of them. Go to Control Panel, Administrative Tools, Services, make sure both computers have the messenger serive turned on. Now if either of you are on a router you can open ports in your router or put your ip on the DMZ host. Which basically defeats the NAT. Instead of your router being the outside world ip it passes everything to your box. Then you know what ip he has and send him the messages. You would have to know his ip though. Here is something you can run if you like more of a GUI for it. http://www.hotscripts.com/Detailed/20290.html Just to let you know I would advise against this. You will open up to a whole lot of message spamming.

:confused: He has a computer and a high speed DSL link, but "doesn't have a phone"......that strikes me as very odd...surely he has a mobile?...in which case send him an SMS message on it.

I am inclined to agree with gamernewbie in that the spam and security compromise is not worth the effort of trying to go the PC route.

If he hasn't got a mobile he should get one. OK I don't know anything about them Stateside, but over here you can get "pay as you go" ones that don't cost a lot. Just about every schoolkid over here has one glued to their hand as if it were a surgical implant :D

Anyway, how do you normally contact him to arrange a meeting or whatever???? Even if you do send him a pop-up or the like, how do you know you will still be on line when he reads it. For that matter how do you know he will still be on line when you get a message from him? you could spend weeks just missing eachother on the net. :(

Just going on my experiences with videoconferencing and netmeetings: we always set them up by telephone first.

we usually stay on gamespy or yahoo. and the bellsouth pple said they would arrange to setup a dsl line so we figured "dsl" never thought of trying a phone.

Here's what you tell him to do. Plug in a splitter and filter the line going to his phone voila phone service. That is the last piece of info for this post. It is beating a dead horse. Either you just want to post or don't get it. There has been enough info on this topic given to you already I would think. There should be phone service there.

After reading this thread and going over the concerns various people have raised over the misuse of the net SEND command (ie; spam), can you please tell us *why* you want to hide your computers name?
I cant see any reason, other than to spam/annoy others. And please dont give us the "i want to freak out my friend because he said i couldnt" spiel, it gets old.

Your friend doesnt run any kind of messenger service? Looks like you need to start hiking it over there.
