I have a win 2000 server set up as a web server with several IP adresses (6
total). I am running FTP service on two of these, but when I port scan, all
of the IP's have port 21 open. Is this normal?
My other services like SMTP and WEB only shows up on the IP's they are
If I try to connect with my FTP client on one of the IP's that is not set up
to run FTP it just says: "Socket connected. Waiting for welcome message."
and then after a while I get a timeout.
Is it normal or are some nasty Trojan listening and waiting for the right

Use port knocking for a more secure method of opening ports
Every open port on a firewall or a router is a security risk.
That's why a technique called "port knocking" can be valuable.
Port knocking is a method of allowing access to firewalled
services given a preconfigured "knock." The knock consists of
a sequence of access attempts to closed ports on a system.
These attempts a...Port 25 open
Greetings! I would appreciate your advice and assistance with the problem of
my Port 25 being held open. I've run the "Internet Common Ports Probe" and
my system fails the "TruStealth Analysis." Port 25 is the only port being
held open - all others are "Stealth."
As recommended in the "Security Implications" field of the report, I
registered with Network Abuse Clearinghouse (www.abuse.net/relay.html) and
ran their "mail relay testing" utility to test my system's port 25 and see
if it can be used as an open SMTP eMail forwardin...SMTP Port open
We have an open SMTP port open on our Small Business server. We use exchange

My question is - how vulnerable are we and what if anything can be done to
Also what can we do to plug it?

SMTP is how the email gets in.

The more I learn about networking the more paranoid I end up getting.
I've got a small home network using a WiFi LAN.
My network operates behind a NAT router and I still use ZoneAlarm.
If I use a Ports redirection to enable a VNC server on one of my
machines what dangers am I exposing myself to!!!
I appreciate the need to have a good password set but what I am
wondering is, when I enable the VNC server it shows as an open port.
This obviously identifies my machine on the internet, once identified
am I vulnerable to any other attacks?

While running a test on probing my ports on the GRC site, port 25 (SMTP) is
open. I tested them a month ago and everything was stealth including that
very port. I am my wits end trying to figure out what I did to cause this.
Here a little info on the specs of my machine:
Windows XP Pro
Zone Alarm 2.6.362
Running AOL 7.0 (unfortunately)
Use MSN Messenger 4.5

Related to the other threads that are ongoing regarding a similar issue it
SEEMS as if some people might be concerned because UDP ports are being shown
as open when they are running being a Stealthing device. This does not mean
that your ports are in fact open. This problem i sbeing cause by the way in
which the UDP protocol works. Since it is a connectionless protocol there
is no set-up or tear down of connections. Packets are puched out of the
computer like a mother bird teaching her babies to fly. If they make it
they make it. typically the way a port scan would see a closed UD...Open Ports what opened them

You can use AtGuard (no longer available), Norton Internet Security /

Sheildsup indicated that I have two open ports. Port 23 (Telnet) and Port 80
(HTTP). I have an ADSL connection in which I use a Cayman NAT router. I also
have ZoneAlarm installed. Should I be concerned and is there anyway to make
these ports stealth?
