The majority are like below only with different versions such as 2.6.2,3 4 5 etc.

/phpMyAdmin-2.6.4-rc1/main.php

I got about 80 of these in the last 4 hours. Is someone trying to hack my website?

Yep, it's a script kiddie cracking attempt

Thanks
I fugured that was a logical assumption. I don't have my own server so they will probably have to be good at what they do to get in. I saw some chinese and taiwan IPs on the log too so I figure that's where they are.

sorry jsut for the hell of it so i can pick up another bit of soemthing,

What are they trying to do, and hows it work
