Network Packets
-
Hmm, just thought I would share something boring with everyone at CP. A certain computer on our network has been on for 5hours 30 mins. In that time, 86 000 000 000 packets have been sent (I rounded the figure, as it was just over). Thats about 260 000 000 every minute. The reason I am not worried about this, is that the network has no clogged up. However, this computer has no virus, so I think there is a definate bug somewhere. I found this in the Local Area Connection Status. Has anybody else received very unreliable results for something that was supposed to work?

I saw this behavior you described on machines with Virtual PC installed (not running, simply installed). Since I've started using Windows, I've seen the most strangest things happening. Some days ago, I crossed what seems to be a kernel bug on Windows XP: I was using this cmd.exe console application, and, after some work, typed 'exit'. Great. It hung. Ok, Ctrl-Shift-Esc, let's kill it. Wait. Where is it? Ok, switch to the Processes tab. Where is it? Ok, check the "Show processes from all users" (I'm administrator). Where is it? Nowhere. Ok, list all processes with other tools. Nowhere. But the windows is there, on my screen. I can move it, I can select text, I can call the system menu. But not kill it. Let's restart the machine. Great. It can't, the hung application do not allow it. Let's press the "Power" button. Great. It can't, the hung application do not allow it. Press reset.

[sarcasm] Geez, that's really strange. I've never doubted the accuracy of any software. I wonder how that happens. :confused: :confused: [/sarcasm] I'm still waiting for the day that I log onto my bank's website and discover that I have a balance of over $1,000,000,000.00. :cool: Chris Meech If you spin a Chinese person around, do they become dis-oriented?

That's quite odd, unless this is a very busy PC. One failure mode for a NIC is streaming - lots of bits sent for no apparent purpose. Have you looked into what type of packets are being sent? Are they meaningful, or just random bits? "Some people are like Slinkies... not really good for anything,

We just found a computer on our network that was sending 20MB of data a day to port 80 on an external website... The virus checker didn't pick up anything. The only way we caught it is because we wondered why our ISP was logging a non-zero data rate overnight and at weekends. We still don't know what is on the computer but its off the network awaiting a format now... Hope yours isn't the same thing. James. James.

T, Is your workstation in questions running DHCP requesting a lease at a specified interval? If so, it could be that the IP Address passed down by the DHCP Server is not being acknowledged by the PC,or non acknowledge from the DHCP Server. At the command prompt type in ipconfig /release this will release the exisitng IP given through DHCP, then type ipconfig /renew and check the log in the event viewer to see if the IP is being accepted. All of the above apply on if using DHCP. If you are using a static IP this could be a problem with the machine searching for the master browser, then you would want to type nbtstat -RR, the RR is for release and renew. HTH Tony

I blocked ICMP in my firewall, and now the stats show ~90% of traffic is blocked. System still works fine, surfing, mail, etc. "It's been swell.. but the swelling's gone down." - TankGERL

The reason I am not to worried about it, is these packets seem to go nowhere. The network itself does not seemed to be clogged (as I am sure it would have been with that many packets going off every minute). So I definatly think it is a problem with the OS or something. But when I source the problem, I will let everyone know, in case anyone ever crosses something like this.

You have the Welchia virus. My ISP cut me off because I was sending out huge amounts of packets also. Go to symantec's website and download the fixWelchia program (free). MS's update didn't seem to catch this one... Another solution is to shut down all RPC services... Ryan
