The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

NETSTAT and monitoring your ports

Tags: netstat, ports
a couple questions i need help on (overall concept should do) --

at a CMD prompt you type netstat -a -o -n....  note any TCP entries with status of ESTABLISHED and foreign address OTHER than 127.0.0.1.  

what's the deal with these sites / ports?   are they actually monitoring port 80 traffic & if so, what can they see?   do keystroke readers operate in that fashion (simply monitoring ports or something).

i'm interested in understanding more about those entries.  please explain.

from what i know about netstat -ano  it will view all the ip address that is connected to you and the port they are using to connect...


let say, you are not doing anything, but you heard your HD very busy, and you are wondering what's going on..    you have nothing open.. so you went to the command prompt and found that you are hosting a ftp server, but you have no idea about it.. and don't even remember installing it..   but the port 21 is point..  

you can now trace the ip connected to you by tracert or some software outthere.. DIG and see where they are and report them to their ISP ..  anway... im out of tract as far as your question..

what i use netstat -an  is to see and make sure i'm not running or no one is connected to me without me knowing it...

hope that help man.

this is very helpful info & resonates w/ what i thought was true; i figured they're connecting w/out my permission & are scanning.

question then:  i'm noticing ports (various from 3716 - 3900) are connected to/ being watched by an external IP.    should i simply block my router from forwarding on these ports to prevent the activity?   or would that just cripple certain functions / make browsing or internet apps slower?   i'm using WPA on a linksys router for security.

last question:  should i instead limit the connectivity to router to my MAC address (and if someone comes over for a visit throw their MAC address in the map so they can connect)... that is, would that also prevent that kind of activity described above?

Rank: Master

You might want to use "netstat -abn" instead. That will show you which program (on your PC) is using each of those connections/ports. If you find any unexplained entries don't hesitate to post them here.

There are many programs on your PC that check for updates etc. (everything from Windows to Java to Realaudio to Adobe to Quicktime to...) that make network connections. Some are more useful than others, so I would not disable anything without first checking who and why.

I am assuming you are running Win XP Sp2. Do check that the Windows Firewall is enabled, though that does not block outgoing traffic.

>You might want to use "netstat -abn" instead.

thanks for that - good trick.

by the way - I'm using something I found to be pretty good:  F-Secure.com's antiVirus /Firewall.   it's great, love it...just like ZoneAlarm in my opin. (both are worlds better, to me, than McAffee and Symantec...as F-Secure and ZoneAlarm give a lot of protection and don't ask a lot of questions.

and thanks everyone for the info.   that's exactly what i use netstat for - make sure there are no other connex w/out my permission.   however every now & then i see odd activity that's *not* related to things that i'm doing...so i was curious how others use netstat / tracert and how people interpret the results.
