Instant Messaging from Linux to WinXP

[mohanty1942]

Mine has fedora 8 (Digit Feb 08 DVD) installed & my friend has WinXPSP2 in the other building (Both are connected by LAN (ips are 192.168.0.2 & 192.168.0.1) .
We can ping each other . Also am able to access internet (currently using) by specifying my friend's machine as proxy server.

Now what I want is to send instant messages (like net send) to my friend (WinXPsP2) without installing any additional software/(configuration change) in his machine.

Please help .Thank you.

If you have samba installed then try:
smbclient -M HOSTNAME message

or use Linpopup:
