I have used both the same computer and a different computer.
I think I've found a work around, I was able to get in today after a bit of playing with it.
As you said, even if I could get it, it should boot me if I were to do something like type help greeting or help greeting2...or for that matter if I type score, but that has never happened.
The only other thing I could come up with, was that the initial telnet packet size might be an issue...it shouldn't be, but denial of service attacks tend to have large packet sizes on odd ports, so when I clicked connect, I immediately hit Enter 3 times so that I was sending small packets at the same time as recieving...basically chunking up and interrupting the receipt of the packet. This shouldn't have worked, but I got in on my work machine and tested it on my laptop as well (both of which were unable to connect just moments before).
As I said, this certainly shouldn't have worked, but at least I now have some semblance of a work around.
