Packet Monitoring
    #4047228 - 04/12/05 08:12 PM (11 years, 7 months ago)

Here's one for you wizards. A week or two ago I noticed the activity light on my cable modem flashing when I wasn't using the internet. This was new, or I had missed it (but I doubt it). I installed AnalogX packet monitor and sat back and watched. Ist up was my ISP. A call to tech support got a claim of it's normal for this to happen. I asked what data was being transmitted and got the answer "It's a data transmission". So helpful. So I used my Norton firewall to block the DNS that was showing. There were a few other DNS's which showed from a company across the country. Blocked it as well. So for a few days no flashing. Then it started again. Tried to fire up the packet monitor but got this message, "Unable to open raw socket". It took an uninstall and a reg edit to get it going again. During this time I've had to reinstall Soulseek a few times as well. The .exe file vanished each time after a day or two. KazaaLite stopped working. So today I had to do yet another uninstall and regedit for the packet monitor. During regular net use the monitor works as it should. During periods of inactivity it shows no packets yet the local area connection status window shows packets dribbling in very slowly

And thoughts? How can packets slip in without the monitor detecting them? What is happening to affect only internet programs?

Oh, and I've run Adaware, Spybot and Microsoft Spyware several times with the latest updates.... as well as several virus scans.

Thanks.

Having to reinstall certain applications shouldn't have too much to do with any windows network related problems? I'd say you have some bug or quirk in windows, it has a tendency to age and degrade like an old man. The packets slipping through could be pings or replies. I wouldn't worry about that too much, just check on background programs in taskmanager that could be checking for updates, thats all I can think of.

The Windows install is only 2 months old. I mentioned the problem programs out of curiosity that both are p2p programs, found that odd.

I did check for auto-updates but I have all those turned off. All the most recent packets are incoming and it takes several minutes to receive 1.

Thanks for the response.

check your firewall logs. Like TinMan said most internet programs deal with pings and pongs frequently to let the server know your alive. Check the task list for wierd unidentified processes. I've seen all of those virus scanners you meantioned miss viruses. The only safe way is just to disable all automation in your browser, etc. There are a lot of registry cleaning utilities out there a dime a dozen these days for cleaning things up but the best way is to look for yourself. If a virus has injected clever code into a process you'll never know. I just had to delete windows because of a really nasty virus that nothing detected. Windows has turned into a huge mess lately, which is why I try to stick with open source software

Reboot you PC, open a msdos prompt and type "netstat -an" without the quotes and hit enter.
You should be getting something like this, probably less lines. The important thing is to identify any "alien" address.
Code:

Active Connections

Proto Local Address Foreign Address State
TCP 0.0.0.0:1025 0.0.0.0:0 LISTENING
TCP 127.0.0.1:1037 0.0.0.0:0 LISTENING
TCP 192.168.0.174:1026 0.0.0.0:0 LISTENING
TCP 192.168.0.174:1026 192.168.0.139:139 ESTABLISHED
TCP 192.168.0.174:1027 0.0.0.0:0 LISTENING
TCP 192.168.0.174:1027 192.168.0.11:139 ESTABLISHED
TCP 192.168.0.174:137 0.0.0.0:0 LISTENING
TCP 192.168.0.174:138 0.0.0.0:0 LISTENING
TCP 192.168.0.174:139 0.0.0.0:0 LISTENING
UDP 0.0.0.0:1025 *:*
UDP 127.0.0.1:1037 *:*
UDP 192.168.0.174:137 *:*
UDP 192.168.0.174:138 *:*



All 0.0.0.0 and 127.0.0.1 are ok. 192.168.0.174 is ok too, it's my ip address, you can see yours by typing "ipconfig" at the msdos prompt, you'll probably need to insert this command if your internet connection is made through DHCP and you have a dynamic ip. Mine is not, but the thing is, you have to do this after rebooting so all connection tables are clean, if you get an endless list then there's something wrong.
Also, you have to be careful about some programs which enable auto-update or auto-connect services - like java or some firewalls or anti-virus also do this. Those programs are usually found running in the system tray, near the date&time. Try turning off, disabling or closing those programs, then try again.
Hope it helps :wink:

Cable modem's have lots of data that comes in even if not all of it is for you. So the light will blink a little bit but the packets that get to your side are destined for you. So this explains why you are having the light blink even when you have your computer turned off. If you don't have a cable modem keep reading for more information

Now to address the stuff thats hitting you computer(the stuff you see at the packet monitor) is most likely traffic that your windows os and other using the isp are generating. Netbios and other things are notoriously noisy stuff. They sends lots of packet and they love sending to the broadcast address, which means that everyone near by gets them. I run a VERY tight firewall that caputres every packet that is not going to a port that I allow(which is quite a lot since I don't run windows. I have 45781 dropped packets in less than a couple days. Thats all traffic sent to me that is not useful. Serioulsy there is a ton of stuff that windows and others generate that if you are running any decent firewall is totally harmless. Don't get too worried.

I hope this helped If you have specific questions, then I recomend you read up on some of the free Open Source packet capturing stuff and then I can try to help you.

Yeap, i completely agree with you nife. Try something like Ethereal for windows, it's an excellent sniffer.
Meanwhile, there are some programs that improve your internet security level besides firewalls, i've tried harden-it. It's a run once software that hardens your IP stack. Get it here http://www.soft32.com/download_77888.html .
