Hi all,

I have network with few win 95/xp machines and suse 9.3 prof server. On
every win client is installed RealPopup (RealPopup homepage: 

I can send popup message from my xp computer to win 95, and I can get reply 
on new message addressed from win 95 computer, so looks like popup 
communication works well.

If I use:

server:~ # echo "test" | smbclient -M bane
added interface ip= bcast= nmask=
added interface ip= bcast= nmask=
Got a positive name query response from ( )
error connecting to (Connection refused)
Connected. Type your message, ending it with a Control-D
sent 29 bytes
server:~ #

Computer "bane" receives message. Again everything works well.

If I commit:

server:~ # nmap -sU zoran

Message can't get through. On my xp computer I am using Norton Antivirus. I 
think it uses some kind of firewall.
Why my xp machine can't get winpopup message?
