NET SEND command

**cracked** · March 26th, 2003, 09:09 PM

hey yall. when i was in 10th grade i took a computer programming class and all of us used to message each other over the network using dos and the NET SEND command.

for the unfamiliar, it goes like this:

net send [ip address] [message, anything u want]

and it would pop up a little message box with the message in it on the pc with that ip address. well what i want to do is be able to do this on my home network. it consists of 2 pc's both running xp pro and connected using a linksys 4port router. for some reason, when i try this on my home network, it says the message was successfully sent but it never comes up on the other computer. how can i fix this to where the message actually comes up?

thanks

instead of ip address, put in the computer name

**sixf00t4** · March 26th, 2003, 09:14 PM

and i also usually put the message in <> dont think it matters though

it is also possible that the service is turned off on the other pc. check in services to make sure the messenger service is turned on

a question. if the computers are not behind firewalls and such, can this be sent to a computer over the internet if the ip address is known? or is it only a local network thing?

depends on whether your ip addresses are routable. if they are something like 10.whatever, or 192. whatever they can not be sent to them..... well i guess they could if you have host names, but really no.

if the computer is directly accessible via a public, routable IP, and is not protected by a firewall, then yes. infact spammers have recently developed tools to take advantage of this and spam the computer with advertisements.

We have been getting a lot of those at school. It's weird when suddenly in the middle of a physics lab there's an almost-simultaneous ding from all the computers in the lab

There's also a switch for domain, which could be useful if you needed to tell everyone using your home network that the router's about to be power cycled, server's going down, etc.

What's the message you get in physics lab?? Sometimes the Messenger service is used by spammers to send spam ... nasty trick. If it's spam, disable the service.
I accidently broadcast across the entire network once when my UPS decided to shut down my PC. Learned how to play with the config to prevent future occurrences.

The message was a spam one about enlarging a certain body part.

I hate it how APC doesn't have a "don't notify me" option in Power Chute. They want to either net send a domain, page you, or email you (at least in the versions I've used).

I did a domain-wide net send at work once.. I was really embarrased, especially when people started net sending me back.

net send 64.81.99.255 "Haha" (for example)

That would send everyone from 64.81.99.2 - 64.81.99.254 that message. A good firewall easily stops them from the internet.

A GUI for this can be found here: http://tomsprograms.toms-world.org/NetSend.shtml .

I use net send at work to tell people I'm rebooting the server (net send /users "Please close all work. The server is rebooting NOW.") Everyone connected to the server will see that message.

Does anyone know where the app for this is, if there is one? (its my only hope at getting it to work on 98, all i want to do is be able to send them from there.)

**implexant** · April 4th, 2003, 08:11 PM

start --> run --> command

type in the commands from there

um... not exactly what i was looking for. You know when you type xcopy into a command prompt? well the app behind it is in C:\Windows\System32\xcopy.exe
and if i write a perl script, and i want to execute it, i type 'perl filename.pl' the path to perl.exe is added to my ENV path. What i want to know is, is there an exe file for netsend?

**Nighthawk** · April 5th, 2003, 04:37 AM

It's the net.exe executable, with parameter send. So you could do net.exe send <person> <message>

I've seen netsend bring down networks... We had a really dodgy server at school and it just got netsend dos'd by like 5 other computers on the network. the network just died....

Does NET SEND work with computers running Win ME as well? I'm running XP upstairs in my room, but I would love to be able to send message downstairs instead of running down (or yelling). If this doesn't work, does anyone know of any good freeware apps that could do the job?

**GroundZero3** · May 31st, 2003, 06:13 PM

used sub only working NT machines running messanger

>If this doesn't work, does anyone know of any good freeware apps that could do the job

here are two...

oh...btw, win98 (& probably ME) does have something similar called winpopup which is part of the 'system tools'.
