A Linux netstat man page at

	http://linux.die.net/man/8/netstat

indicates that there's a "--process" flag that shows the process ID and process name (probably the first N characters of the last component of the executable name, or something such as that) of the process that owns the socket; you have to be super-user to get that for processes not your own.

lsof might also be able to get some information of that sort on some UN*Xes.

Thanks Guy for the info. On windows the format is "Netstat -b". I do not see any associated program that started the connection. I suspect that programs that monitor the IP processes like WhatsRunning and System internals, under windows, are just issuing Netstat commands and then capturing the output and display their own display window. At least that is what I have done in the pass when writing that type of interface using Java.

Again, thanks to you all of your guidance in this thread. This could be a mute issue since I am building a new computer and plan to use a different and newer windows OS. That is, WinXP SP Pro 64bit which may open another can of worms so to speaks


Well after looking around and looking at SmitfraudFix output I see something that is not correct.

Not sure why these IP address are defined as a DhcpNameServer in the windows registry (Not Comcast): 207.68.160.190 194.25.2.129 208.67.222.222 ,207.68.160.190 194.25.2.129 208.67.222.222

Not sure how to get rid of them either. Instructions I see about these setting is to avoid changing them. Which does not make sense since I do not think they should be there in the first place. Not realy sure if this is apart of any problems I am having but does not look right. Guess I need to know the implications of having them defined to DhcpNameServer.

Just wanted to close this thread with a happy ending. I finally resolved it yesterday. Long story short it did turn out to be Trojans. Its just that the four virus programs, I run all of the time, never pick them up. Once I had the 4 Trojan names I still could only find a few references aka Google Search. So I guess they are fairly new ones. Oh the program that caught them is a free one and is called 'AVG Free Advisor', http://free.grisoft.com. I happen to find it mentioned in the forums and newsgroups I visited trying to determine what type of software problem I had.

You all where right about the ARP traffic. That is, ARP broadcasts were taking very little bandwidth. and that was normal volume. Well not being a network person I just had a hard time reconciling the light on my cable modem being lit on all of the time and I was not downloading\uploading anything. It was not the ARP traffic but the other "Call HOME" traffic.

When I use Wireshark now to look at my network card I see the same ARP traffic load but the modem light goes only only sparingly. I think that is just the handshaking with the DHCP server.
