I do not know how to close Port 23, all tests show Open Port 23
« on: January 05, 2007, 10:14:14 PM »
 (:AGY) I am connected to the Internet with a USB D-Link WAU 1340, and connected to a WiFi (Wireless) connection, this connection is at a RV Park that offers this connection thru TengoInternet is the ISP, I took tests Shields up the Port probe, and at PC Plank and both say my Port 23 is open all others are stealth, I do not have Telnet which is who I thought used this port and from reports read this is not a good port to have open, why does it have to be so difficult why can't you just close this port by clicking close port #--? I am so exhausted reading all these configurations that I do not even understand at all the site of Steve's I read for 4 1/2 hours and got no where and more confused now than ever, so please help me, I had Sygate but could not figure that out either so this firewall is new to me seems pretty good, but do need help on figuring this one out.

Hope you can help me.

Please don't get me wrong, I am not upset with Comodo, just myself and the whole port problem.

Hi Pistal and welcome to the forum.
You really don't have a problem, These port scans are scanning the router ip that you are connected to at the rv park.Have a look at cpf logs to see if it shows any details of blocking these port scans, I believe you'll see that your computer hasn't been probed. Hope this helps.

No, I think you are right, I don't show anything bad not blocked, its just when you see this port 23 warning on these scans it scares you (you know CC# theft, trojans, etc.)  Even though I have no Telnet installed it just tells me port 23 is not stelth, it is just open even tough no program is using it? still scares you when you read all these things, I think I am safe, this Steve's site can confuse the heck out of you if you are not a computer geek, me I just would like programs to just take care of these problems by their selves, I just panic'd when Steve's site and PCPflank said my port 23 was open and find out why and how to close it, even though I have nothing on my computer that shows that any program uses this port, Thank you I guess I will just assume that it is ok.

I am NOT an EXPERT - But have had a similar experience.

Hi Pistal

I also had concerns with my tests on GRC in which I failed the "True Stealth Test", because my machine responded to the "ping" test. A simple statement [at the test point] to remove the dread that although the test has in some way penetrated your system that you should now check ................ [whatever]. Resorting to several searches and digesting many suggested answers I accepted that the ping was a normal response to a probe directed at the routers address rather than my system address.

However I am not convinced that any Port should be detectable as open, please step in any knowledgeable contributors and put me to rights if necessary.

Not exactly a lover of large corporations I approach what they offer with caution, but at present Google is my friend when it come to internet searches. I ran a search on:

Close Port 23

The first result can be seen at:

http://pcpitstop.invisionzone.com/lofiversion/index.php/t103590.html

This item suggests stopping the Telnet Service and if this is what you have done already you might like to review more of the links. [(:SAD) about 31,200,000 for close port 23. which took all of 0.11 seconds (or so Google says) (:TNG)]. Seriously there is plenty [far too much?] to look at for those of us trying to get to grips with setting up realistic security.

Please reply and let us know how you get on, your experience may help others with similar concerns.

HTH.

I never turned off Telnet Service, because I don't have it and never did? In my list of Services I do not have Telnet listed, I have Task Scheduler, TCP/IP (not running), Telephony (not running) Terminal Services, and Themes in the T's is it listed under a different name?

I also do use Google and did read arount 4 1/2 hours of that and Steves site and nothing exactely tells you how to close that port except the Telnet service (which I do not have and never did) I guess I will assume the no log file being correct.

As far as I know, If you use XP Home, Telnet won't be listed.  This component is part of
XP Pro and not XP Home.

Quickest way to check your open ports status is to start a Command Prompt, and type in:
Netstat -an
This will list out which ports are open and which your computer is listening to (look at the Local Address column). Verify that the Telnet Service is disabled. This will keep TCP port 23 closed and prevent it from being accessed.
The fact that it's detected as open on the router/modem is a bigger concern, but not necessarily yours as it turns out :)

Hope you can help me.

The sites you are on to test your PC shows you what IP you have.
Is it the same IP as you get if you go to start/run type "cmd" click enter.
Type ipconfig andd look what IP you have. Do they match?
If not, you are doing a portscan on your router.

Typing in the Netstat -an shows my ip address correct, when doing the port scan at Steves site does show a different numberit shows a sd.sd.cox.net number starting with WSOP-70-166 number mine is a 192- number so even with no firewall it shows the same numbers so I am safe even without a firewall? wierd, but I will keep my firewall,  I thought the number that showed up on the port scans was a hidden number (R), thank you now I feel safer, was worried about giving my CC over the internet. Thanks a whole lot.

Yes you should keep Comodo firewall, since the router firewall only protects from inbound connections. You want to have a software firewall to protect you from something that tries to send out from your PC.
192.168.X.XXX is a internal network IP.

Hi,

the port 23 is open on your "box" (routeur/DSL box). It's really strange. If you can manage your box, it would be good to close this port.

You should ask a friend to try a telnet with on the IP adress you saw during your last test (external IP, not 192.X.X.X like). If your friend get a login, it is a security problem.
