A script is most likely attempting to gain entry to your server to hack your system.

I run a script that checks the logs every minute for failed registrations then adds the IP to iptable reject list.

Intrusion detection is what you're looking for.

thank you so much callcrazy
im a newbie.
I'll try to read IPtable reject... is that the one that black the IP of the intruder
right?
