i was wondering how to talk between computers in msdos on winxp. They teacher said he used to let students do it till it got out of hand and then he said if anyone does it now they will b kicked out of the class. I just wanted to know how to do it

"net send "

computer = IP/domain/computer name

you can also use a commando in autoexec.bat so it spamms like 1mmsg per sek or faster....

(have forgotten the code*temporarily*)

... reminds me of when I used to talk to teachers over the school network (novell). Some of them were so computer-illiterate they didn't even know anyone was trying to talk to them.

I want to test it at school, is the command "net" installed on Windows 98 ?
If so, can i actually send msgs with it ?

No, it is not installed on 98. NT/2K/XP only. But if you are on one of those OS's then you can msg people no problem. Assuming messenger (no, not msn messenger) is turned on, which it is by default, then you can pop a window up right in the middle of someone's screen. unreal and SilentRage posted how to use it above.

When I ran my site on my own box, I would look at the logs and see all these attempts for IIS exploits. So I'd look at the IP and send em a message. Good fun...

its bascially like unreal said:
net send "computer id" "your content"

I know of the command net send but I didnt know that you could send it to everyone on the network.
When I tried: net send * (message), it only sent it to my domain (mshome), is there a way I can send it to all domains. The dos program did say the correct syntax for the command but i dont think i got it right.
Any help would be appreciated.

Microsoft Windows XP [Version 5.1.2600]

C:\>net send /?
The syntax of this command is:


NET SEND
{name | * | /DOMAIN[:name] | /USERS} message

Go John, If you hadn't, I would've:D

hahaha. net send is fun. i did it at my school for the domain and sent a message to every computer in the school including the headmaster's. lol. techs should have had it blocked (now it is).

when i try net send there always come`s something like The message alias could not be found on the network.

What is the net send equivalent in *nix.
I need it badly.
