When law enforcement sends search warrants to an ISP, it can take weeks or months for the ISP to find time to dig through their logs and find the exact customer.
First time I had to do something like this I learned how to do it. Second time I was paying attention to what might change. Third time I wrote a script. Subsequent times were just running and maintaining said script. I may or may not have let management know I had a script.
That said, the labels can pound sand.
Kind of ironic in a country that makes the darn things.
Wonder what it's like in a Chinese Wal-Mart? "Hey! I made that yesterday!"
"The Computer made me do it."
