"net send <computer> <message>"

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 ?
Posted By: Infinite Re: messaging in dos - 11/30/02 07:11 AM
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

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).

I need it badly.

is there a diff between command prompt and dos?
I was wondering how you use dos to hack
Posted By: Gremelin Re: messaging in dos - 11/09/04 12:58 PM
Dos is an operating system, early versions of Windows where a program which ran on top of Dos (1.x - 98); Dos is now integrated into Windows (ME+).

You cannot use an operating system to hack; you can use programs to use to aid in "hacking".

For note, command prompt is the same as the command line, and no you cannot use dos to hack.

I was wondering if it is possilbe to send a net message to people that are not on your tcp/ip network but over the internet using net send, providing you know their ip address? I can get net send to work on my own comptuer, but when i tried replacing the name of my computer with my ip address it says the message alias cannot be found on the network. Any help ywould be appriciated.

try

c:\>net send 127.0.0.1

or

c:\>net send localhost

and yes it can work over the internet. Just get your friend to do a

c:\>ipconfig

He will get something like this

Code
Ethernet Adapter Local Area Connection:

     Connection-specific DNS Suffix . .:your.isp.con
     IP Address . . . . . . . . .: 199.99.9.999
     Subnet Mask . . . . . . . . : 255.255.255.0
     Default Gateway . . . . . . : 199.99.9.3
c:\>
Tell him to give you the IP address. Now this will only work if they are on XP, 2000 or NT4

It must be an NTFS system or you have to install "Net Send".

I set up something to log connection attempts on my home computer and would attempt to connect from friends houses really quickly, that way when I went home I would netsend them messages and they would get freaked out or pissed off because it will knock you out of a video game since the net sent message goes to the front window...

I was messing around on my wireless network at home and could not get the net send command to work.

"the message alias could not be found on network"

but i do it all the time at school... there are also no firewalls running on any machines, just the router.
Posted By: Moffesto II Re: messaging in dos - 06/30/05 02:39 PM
never mind actually, found the answer to my problem... enabling the messaging service in admin tools.
