I'm pointed to as culprit
I have a friend (of a friend) who administering a dedicated RH server we contracted from an ISP. In the beginning I was given a user ID and password, but I never used it, I went through the administrator always.
A month or two later the administrator seems to have suffered an intrusion, and feels that it is me, principally because the intrusion comes from the same range of IP addresses I typically use (my ISP gives me a dynamic IP address) and that I have a password.
This is all I know. Is it reasonable to link my knowledge of the password and the IP together and accuse of intrusion? Does he have a point?
I've seen no fishy business on my own machines, so it's all highly odd. But what can I say in my defence? Can the IP evidence be called coincidence?
