Port Authority Edition - Internet Vulnerability Profiling
by Steve Gibson, Gibson Research Corporation.

Checking the Most Common and
Troublesome Internet Ports

This Internet Common Ports Probe attempts to establish standard TCP
Internet connections with a collection of standard, well-known, and
often vulnerable or troublesome Internet ports on YOUR computer. Since
this is being done from our server, successful connections demonstrate
which of your ports are "open" or visible and soliciting connections
from passing Internet port scanners.

Your computer at IP:

212.194.20.1

Is being profiled. Please stand by. . .

Total elapsed testing time: 0.563 seconds

Solicited TCP Packets: RECEIVED (FAILED) - As detailed in the port
report below, one or more of your system's ports actively responded
to our deliberate attempts to establish a connection. It is
generally possible to increase your system's security by hiding it
from the probes of potentially hostile hackers. Please see the
details presented by the specific port links below, as well as the
various resources on this site, and in our extremely helpful and
active user community.

Unsolicited Packets: PASSED - No Internet packets of any sort were
received from your system as a side-effect of our attempts to elicit
some response from any of the ports listed above. Some questionable
personal security systems expose their users by attempting to
"counter-probe the prober", thus revealing themselves. But your system
remained wisely silent. (Except for the fact that not all of its ports
are completely stealthed as shown below.)

Ping Reply: RECEIVED (FAILED) - Your system REPLIED to our Ping (ICMP
Echo) requests, making it visible on the Internet. Most personal
firewalls can be configured to block, drop, and ignore such ping
requests in order to better hide systems from hackers. This is highly
recommended since "Ping" is among the oldest and most common methods
used to locate systems prior to further exploitation.

Status Security Implications

<nil>
Closed Your computer has responded that this port exists but is
currently closed to connections.

21
FTP
OPEN! FTP servers have many known security vulnerabilities and the
payoff from exploiting an insecure FTP server can be
significant. This system's open FTP port is inviting intruders to
examine your system more closely.

22
SSH
OPEN! Secure Shell provides a secure-connection version of the
Telnet remote console service with additional
features. Unfortunately, the SSH services and their security add-on
packages have a long history of many widely exploited buffer
overflow vulnerabilities. If your system has this port exposed to
the outside world you should be vigilant in keeping your SSH service
updated.

23
Telnet
OPEN! Telnet provides a remote command prompt window which allows
remote systems to be configured and controlled. Any system that
appears to be offering a Telnet connection - like yours is right now
- is offering the potential for total command-level access. Since a
surprising number of Telnet servers are known to have no password,
this open Telnet port will be attracting a LOT of the wrong kind of
attention. If your network contains a residential NAT or DSL router,
it may be that its "WAN-side" management interface is open and
accepting connections. No matter what the cause, you should
immediately attend to this open Telnet port.

25
SMTP
Closed Your computer has responded that this port exists but is
currently closed to connections.

79
Finger
Closed Your computer has responded that this port exists but is
currently closed to connections.

80
HTTP
OPEN! The web is so insecure these days that new security
"exploits" are being discovered almost daily. There are many known
problems with Microsoft's Personal Web Server (PWS) and its
Frontpage Extensions that many people run on their personal
machines. So having port 80 "open" as it is here causes intruders to
wonder how much information you might be willing to give away.

Closed Your computer has responded that this port exists but is
currently closed to connections.

cette adresse ip est assez impressionnante et il me plairait d'être
informé et de prendre connaissance de l'adresse ip fixe d'un autre
abonné de club-internet.

Bonjour

J'ai quelques connaissances réseau et tout ce qui se dit la me laisse pantois.

- Dyndns ne peut pas changer votre adresse IP, dynamique ou non. Seul le FAI le peut sinon vous ne pourriez plus vous connecter étant donné qu'il ne vous connait que par cette adresse.

- Dyndns associe simplement votre IP courante avec un nom de domaine DNS fixe ce qui permet de faire fonctionner les applications (exemple FTP) qui font des échanges par rapport a un nom de domaine (sans s'occuper des adresse IP)

J'ai remarque que même certains sites spécialisés n'ont pas compris cela.
