Two networking questions...

[Guest]

Hey guys, I have two questions to ask.
Is it possible to detect the IP address of a computer that is connected to
yours on a LAN? Here's the situation, when I log onto our school network on
campus I share songs via iTunes. And I was sitting there wondering today if
there is any way to find out which IP addresses are streaming music from my
computer. I imagine that there must be 3rd party programs that can do this,
but really don't know where to look (and I kind of hope that there is some
way of doing it included in Windows).

Also, is there a way to send a message to other computers on a LAN based on
their IP address? An engineering friend of mine did it once in our
engineering lab from the command prompt; I can't remember how he did it, or
even if it is just made possible by a program installed by our network
administrators. It just made a little message window pop up on the
destination computer with the sent message and an "ok" button. Any ideas?
Thanks.

at command prompt type ipconfig /all that will give you all your network ip
address's attached, second point you can do this, but unfortunately I can't
remember myself either.

Ben,

For identifying computers connected to yours, the simplest solution is netstat,
as in "netstat -an". Netstat is built in to Windows, and is very simple to use.
For a GUI version of netstat, get TCPView (free) from
<http://www.sysinternals.com/ntw2k/source/tcpview.shtml>.

Neither Netstat nor TCPView will actually show you which computers are actually
using bandwidth. For a really good list of bandwidth users, get Port Explorer
(also free) from <http://www.diamondcs.com.au/portexplorer/index.php?page=home>.

Ben,
The service you refer to is Windows Messenger. It is commonly disabled
because messages are often sent from the internet and appear as popups. At a
Command Prompt, type net send <destination computer> <message> [enter]. The
destination can be IP address or NetBios name. This works for me. I am
behind a NAT so I don't get the popups that others report. Also, as I
understand it, the service cannot be disabled in Win9x versions, so if you
are using those, you should be able to do this.
