`Just do it,' Pad said. `No time to worry.'

Phoenix whispered the Internet IP address of the NASA machine to
Gandalf.

`OK, m8, I'll anon FTP it to NASA. I'll come back here and tell you the new filename. Then you go in and decrypt it and uncompress the file. W8 for me here.'

Ten minutes later, Gandalf returned. `Mission accomplished. The file is there!'

`Now, go go Pheeny!' Electron said.

`Gand, whisper the filename to me,' Phoenix said.

`The file's called "d" and it's in the pub directory,' Gandalf whispered.

`OK, folks. Here we go!' Phoenix said as he logged off.

Phoenix dashed to the NASA computer, logged in and looked for the file named `d'. He couldn't find it. He couldn't even find the pub directory. He began hunting around the rest of the file system. Where was the damn thing?

Uh oh. Phoenix noticed the system administrator, Sharon Beskenis, was still logged in. She was connected from Phoebe, another NASA machine. There was only one other user besides himself logged into the CSAB machine, someone called Carrie. As if that wasn't bad enough, Phoenix realised his username stood out a like a sore thumb. If the admin looked at who was on-line she would see herself, Carrie and a user called `friend', an account he had created for himself. How many legitimate accounts on NASA computers had that name?
