Steve I know your IP address join: You're not seeing "Network Blackjack" and have been mislead by the list of registered ports. This list can only really be read in one direction: But the converse "if you're seeing that port, then it must be the certain application" is not true except for only the most well known services.
In general, for a client to talk to a server, the client must know the IP address and the port number of the service it wishes to interact with: Most of the time, the client has built-in knowledge of this port information, so for instance your web browser knows to hit tcp port 80 to fetch a web page. There is a fair list of these services that are so well known that they are known as "well known services" mouthful!
The point is that the client has to somehow know how to find the server, and most of them are done with well known ports or built in knowledge.
But there are only 64k possible ports and way more than that many possible services, so how do we share these scarce port resources? In addition to the "obvious" applications such as mail or DNS server, your computer often runs a larger list of small services that need to listen for requests from the network.
Sun machines can have dozens of these minor, administrative services that users don't see directly. NFS doesn't reserve a half dozen port numbers, so when each of the various services start up, rather than listen on fixed, predetermined ports like web, mail, DNS, etc. So the system looks around - often starting just at port and finding one that's open.
This means that is often the first one given out. As you saw when you shutdown svchost on — see all the relevant services that went down with it.
I bet if you scan each of those ports, they'll show closed or stealthed too. Rickster , Aug 1, Technodrome , Aug 1, MyNethingieMan, Technodrome, and Rickster Have you tried this program yourself?
