Windows Internet Privacy

Hi all, I've been away from the forums but still keep frequent with the aMSN svn.

I have a simple question I hope but slightly off topic. I'm using Yahoo Messenger and I someone has been pinging my yahoo port to see when I am connected to messenger.

I was wondering how I'm able to find the times when exactly they are pinging me either through a program or a command using Windows Vista.

Thanks.

humm.. I have no idea, and you're probably asking at the wrong place... my solution would be to write a small program that would listen on that specific port and would print to me everytime it received something...

Actually there is no such thing as a port for ping, since it works with the ICMP protocol, which does not need a port to work. But in this case we are not talking about a real ping, but about someone who tries to connect to a TCP port to see if it's open (a port scan). You could find out this by using a packet sniffer, as it would be tcpdump in *NIX world or Wireshark. You should ask the sniffer to display only TCP open requests on the Y! port.

kjir, yes, a ping is ICMP, but he said "ping my yahoo port", so I understood it was a tcp port connect :p and yes, wireshark (for windows/linux/whatever) would do the job, but if he doesn't tell it to only sniff the appropriate port, then he would get a huge memory hog, until the process dies...

Thanks for the replies. I'm not too familiar with this stuff so maybe I used the wrong term when explaining but I hope I was understood.

I've downloaded Wireshark and am currently trying to figure out how to configure it now.
