Alert alert alert alert......

My ZoneAlarm is alerting all the time when I'm out and surfing! Most of all alerts is incoming connections to some UDP ports. I have no damn idea what the heck is listening on these ports! Is it Windows programs or what? Do you know perhaps where I can get info on what is listening on the ports? Rickard Andersson@Suza Computing C# and C++ programmer from SWEDEN!

That's why I use Outpost, the warnings are less intrusive :) I think some script kiddies are trying to connect to your computer (connection on UDP 137 could crash a Win95/98, that's why it's often tested :~ ). Doesn't ZoneAlarm indicate the IP address of the people trying to connect?

Unlike TCP, where a virtual circuit is openned and agreed upon by the sender and receiver, UDP doesn't require anyone have registered interest in receiving UDP packets from a sender in order for that sender to send those packets. For instance, I could write a small program right now (if I had your IP) that would send data to your UDP port 12345, even though no application on your machine is "listening" to UDP port 12345. This is in contrast to TCP, where I would first have to open a connection (the virtual circuit) to your TCP port 12345 before I could send data. This, of course, would fail because you don't have any app that is listening for client connections on TCP port 12345. So, long story short, the UDP packets you are receiving might be unsolicited. -- Russell Morris "Have you gone mad Frink? Put down that science pole!"

Cool information you gave me! Thank you! This "question" perhaps sound like a programming question... eek... :~ :suss: Rickard Andersson@Suza Computing C# and C++ programmer from SWEDEN! UIN: 50302279 E-Mail: nikado@pc.nu Speciality: I love C#, ASP.NET and C++!

The "IP Look Up" utility I have tells me where the IP come from, sometimes it's from Nish (India), sometimes Thiland, Korea.... etc. etc.... :) Rickard Andersson@Suza Computing C# and C++ programmer from SWEDEN!
