Help with my LIDS

Hi,

I consider old dude here. I am having problem with LIDS indicating
portscan. Its normal but why this messages:
-
-
LIDS: killall5 (dev 3:1 inode 23497) pid 14278 ppid 14274 uid/gid (0/0)
on (null tty) : Port scan detected: 66.230.239.174 scanned 31 closed
ports including 0 ports < 1024)
-
-

why killall5 making a with portscaning from another hosts.. as far as i
knew all ports are block in my firewall rule tables.

any experience over this, please help me out! I am hosting public shell,
i confident its is hacked then attempted.. am i ?


thanks,

jsuthan
