If this has to be public ftp, make sure to keep your system updated, use selinux, and you may consider limiting NEW connection types via iptables, which should slow down junk like this. If it's ftp just for you and some friends, restrict it to known ip addresses or use sftp/scp instead. -- During times of universal deceit, telling the truth becomes a revolutionary act. George Orwell
