Syn attacks reach the ftpD (21) port even if the port 21 is closed and firewall running in stealth mode

netstat -s result:

 0 STREAM         ftp..21         ftp..21    23.225.152.7  SYN_RCVED
 0 STREAM         ftp..21         ftp..21   154.91.38.145  SYN_RCVED

so that the ftpD (Moylan's ftpD) becomes out of control and must be task-killed

if still an issue with 4.2.3, we might look at it again.
