  19:43:00: Pings-of-death: requested
  19:43:00: Testing level: standard
  19:43:00: doing basic ICMP ping
  19:43:04: Running tcp SYN (half-open) portscan, source port 20, over 1-1024 plus 1026 common tcp service ports.
  19:48:41: Running tcp SYN (half-open) portscan, source port 20, over first 140 ports.

icmp
(help)
comment if your security logs are good, you may have logged a ping.
  advice To be totally invisible to the internet, your IP address should not even be pingable. No points are lost in this test for being pingable, as it is not a security risk.
  result Your address is pingable
udp
(help)
comment one or more UDP services can be inferred,
  since all other UDP ports are providing port unavailable packets
  result There are some udp ports open
  full udp scan can go ahead
  score Points Deducted:3
tcp
(help)
comment port filtering is sometimes done at the ISP, or more often on your DSL equipment, or in firewalls or security software
  result There is 1 or more tcp ports filtered
udpfull
(help)
comment even basic firewalls should log a UDP scan attempt here.
smtphealth
(help)
result Cannot do requested SMTP server health check because I dont see port 25 open
nmap-syn
(help)
comment TCP port results from SYN (stealth) scan:
 
Port State Protocol Commonly
1080 filtered tcp socks
109 filtered tcp pop-2
110 filtered tcp pop-3
119 filtered tcp nntp
137 filtered tcp netbios-ns
1383 filtered tcp gwha
139 filtered tcp netbios-ssn
162 filtered tcp snmptrap
194 filtered tcp irc
53 filtered tcp domain
67 filtered tcp bootps
80 filtered tcp http
81 filtered tcp hosts2-ns
88 filtered tcp kerberos-sec
99 filtered tcp metagram
nmap-synfrag
(help)
comment fragmented packet scans are network intensive, so only first 140 ports are tried since if your firewall blocks services, it would certainly be trying to block something in this range.
nmap-tcp
(help)
comment TCP port results from basic scan:
 
Port State Protocol Commonly
80 filtered tcp http
nmap-syn
(help)
comment If your security is good, you get an alert of a scan attempt but this is a stealth scan, so it is difficult to detect.
nmap-synfrag
(help)
comment No results from the FRAGMENTED PACKET scan
nmap-udp
(help)
comment UDP ports. Please verify each one listed:
 
Port State Protocol Commonly
520 open udp route
67 open udp bootps
69 open udp tftp
final
(help)
comment
Conclusion: FINAL SCORE: -3
  ** good result.
