This is from my error log and what I get in 0.5 secs and its all from the same ip.
I'm not so familiar with iptables and stuff.
Please help me

 

[pm7b]

hmm, what verision of XAAMP are you using?

 

[Ricczor]

I'm using the latest LAMP. But what has that to do about this?

 

[pm7b]

I see, i can't help you, since I am not that good with the latest version of LAMP. I'll ask my friend if he knows how to solve your problem...

First of all remove the ip, you're not allowed to post that here.

Secondly download peer guardian and it has some settings to prevent ip's from connecting to you.
