Semi-spoiler: the protagonist used to sleep next to
his terminal (leaving
his girlfriend alone) until the perp tried to log in, upon which alarms went
off and he was finally able to trace the call.
Or am I confusing it with "The Cuckoo's Egg" by Clifford Stoll?
You might be. At least, what you describe definitely bears a close
resemblance to events recounted in Stoll's book. Of course, that by
itself doesn't mean something similar can't have been done by or
happened to others. When all you've got is a hammer...
