hello, I am setting up a wireless Ad-Hoc network manually in linux using iwconfig and ifconfig. I have gotten everything working, and I think I understand it all except access point. The part that confused me is this: If I have essid='some_id', channel=11, Mode=Ad-Hoc and appropriate routing/ip on both laptops, why do I need to make s...
Hi everyone! I just wanted to know if any of you had any problems using java default HttpURLConnection class. Some kind of bug that made you switch to apache commons. Or is it just the (ugly) interface that class exposes that justifies the birth of 3rd party http lib? Disclosure: I heard some arguments against java.net having some ser...

Although I might pretend very well that I know a thing about networks or security and it might help me pass an interview or fix a bug, I don't really feel I'm fooling anyone. I'm looking for laymen explanation of current network security concepts and solutions. The information is scattered around and I didn't find a resource for "dummies...
Hi All, Is there an elegant way to make a program detect a new computer that is connected to the network? I would like my program to "auto-sense" a new computer being connected on the network (they're on the same network). Like a USB device being connected to the computer.
