Lesser: The answer ist the "InterNIC"-Server.
F4LL0UT: I've always been wondering. At some point I came to the conclusion that the Uplink Test Server is the best answer since they won't bust you for hacking this particular server (after all, getting caught by this server is even part of the tutorial and doesn't cause any consequences). So isn't erasing the logs of this machine just as good as InterNIC? I was surprised to see that most people use InterNIC although some players use the Test Server. Is there any particular reason why InterNIC is better than the Test Server?
Btw: "Ist". Haha, you Germans crack me up (just kidding, German is my first language too and I make the same typo all the time :B).
If you make the InterNIC the first bounce then it becomes the last place a trace looks for anything suspicious. If you use the best log deleter and you have a fast gateway, then just delete every single log in the InterNIC...or if you are feeling mischievious, leave the logs but modify the proper ones to point towards someone else entirely. :D
