I am running a Debian server with PHP5, Apache 2.2.16 and PHPMyAdmin (I don't know how to check the version number), Logcheck and some other programs.
Today Logcheck begin to attach multiple lines like this, and I do not know how I can prevent them

Should I block the IP using IPTables or how?
And if I am going to use IPTables, how should I insert the lines?
