View 3 Replies View RelatedI was examining my router's logs the other day and I noticed a recurring entry stating that my PC's IP address was sending packets to the IP 172.16.30.115 on port 80, and that the router was dropping them.Except for the fact that my home LAN uses the 192.168.1.0/24 network EXCLUSIVELY. That is all it has ever used since this router was set up, and the only other networks we have EVER used are 192.168.0.0/24 and 192.168.2.0/24. So why, I wondered, is my PC repeatedly sending (presumably) HTTP traffic to a private IP that is not and never has been on my network?I wasn't worried about what these connections might be doing, since I figured they couldn't do anything, but I was kind of concerned about what was generating this traffic in the first place. So I downloaded Wireshark and ran a capture for 30 minutes. Upon completion, I filtered results to show only packets that contained the IP 172.16.30.115, as either the source or destination IP.Based on the router logs, I expected to see three packets with my PC's source IP address and a random source port sent to 172.16.30.115, port 80 every 10 minutes.And I did see that. These are TCP packets, and they appear to be completely empty. The only thing I noticed about them is that the SYN flag is set. I don't know what the significance of that is, if any, but that's what I noticed.
What I DIDN'T expect to see were the packets that had a source IP of 172.16.30.115. These packets (also TCP) had the ACK and RST flags set, and they contained the text "Go away, we're not home." So not only are there packets being sent to an IP that cannot possibly exist within my network, but there are also packets coming FROM the impossible IP telling me to go away.All of that is scary enough on its own. But then I hopped on Google and did a search for the phrase "go away, we're not home," and almost every result was related to the decline of the Storm worm. After reading about Storm, I was more confused, not less. In its heyday, Storm used UDP traffic to communicate between peers, and my mystery traffic was TCP. Storm usually did not use well-known port numbers, such as 80, which I read was part of what made it so resilient. Not to mention that the most recent posts I could find regarding the Storm worm were dated 2010 and were about the possibility of a second Storm, and I didn't get this PC until May 2011. Plus, even if we ignore all of this and operate under the assumption that I have the Storm worm on my PC, that still doesn't explain the fact that the traffic from my computer is heading to a private IP that is NOT, I repeat, NOT being used on my network, my router says it's dropping this traffic, but my PC is still somehow receiving a response from an IP address that 1) isn't on the network and 2) can't be having any packets forwarded to it, since the router says it's dropping the traffic.So, operating under the worst-case scenario assumption, I used two different virus scanners (not simultaneously, of course) to do the deepest scans they are capable of doing. They both turned up completely clean. In fact, I've had AVG Free installed on my computer since I got it, and even if you look at my virus history you only see a few tracking cookies, a corrupted EXE from the Skype setup folder, and a Trojan dropper that I never even ran because I thought the file properties seemed fishy so I scanned it and promptly deleted it. So I now have to go back to operating under the assumption that I do NOT have the Storm worm, and I am back to the drawing board.
During the last month or so my internet connection keeps stalling and will not work until I repair the connection, however I am still connected to the network, I just can't send or receive packets. In particular when I am downloading things, it will stop after 2MB is downloaded or 300MB, it just random. After sending/receiving 7,000 packets or 700,00. This only happens to my computer with the wifi adapter. Prior to this I didn't have any issues for over two years. My phone and laptop still connect via wifi to the internet. And the xbox and blu ray player are connected via ethernet and have not had any problems. The log for my router states "deauthenticate reason 3", which I have found to mean "The access point went offline, deauthenticating the client". So, I figured that the issue could be the wifi adapter which I installed on the laptop and that too never had an issue. I used inSSIDer 2.0 to see the close by networks and changed channels to get away from the strongest ones. I tried switching to wireless n only instead of g and n, the problem still persists.
Then I figured the issue must be my computer and no malware, spyware, adware nor any virus was found. The same thing happened while in safe mode. I also tried the winsock fix to no avail, reinstalled the wifi adapter and made sure all firmware for the router and adapter were up to date as well as XP. I also tried with my firewall shutdown but I still loose the connection. So I then reluctantly did a clean install and even with the bare essentials it still stopped working. I also bought a 15ft USB extension to get a better signal but still, even though I have a good or excellent signal I still have problems. My latest thought was this was the only machine running firefox 4 so I went back to 3 and that didn't either. I checked my usage with my ISP and I am no where near the 250GB a month.
I keep getting disconnected and blocked from using even LAN on my computer. This happens whenever I visit certain websites. For instance, I registered on a website that has me "kept signed in", and whenever I click to view that website, it partially loads and then for precisely 1 minute any network activity I try (like visiting my router configuration page, or clicking refresh or home to load google) will not go through. Only after that one minute is over with, I can resume browsing that website; however, if I leave it for too long, and then return, the same thing happens.
I've also noticed that if I sign out of that website and then visit it, that disconnect issue won't happen.But that isn't the case with other websites, as they require no accounts and are just pages with news and other stuff.I tried uninstalling and reinstalling my ethernet drivers, tried flushing dns, renewing ip, releasing and some other /cmd stuff that I found online.This also doesn't happen on any of the computers connected to my router (although, they are all using wireless - I am using cable to router).I'm on windows 7 x64, using a realtek ethernet card, Nod32 security suite (think it may be the settings on this thing? I set everything to super safe settings so I don't get any dumb viruses). Windows is updated (well, at least 3-4 months ago it was updated). I have no idea what is causing this, and why the precise 60 second interval until I regain access to the internet.I'm using Firefox, but this also happens on IE8 or 9 or whatever I have installed, so I don't think it's a browser issue.Things like facebook, youtube, pennyarcade and other junk work, but as soon as I go to google looking for, say, apartment rentals and open some pages, one of the links in the search results is bound to make my connection freeze.

Here is my scenario : 5 users on a network with their own workstations, IT Technicians, Sales and Marketing, Admin, HR and Manager...All these users need to access different files on the network so here is what I want, I need for the IT guy to log on into his PC and only see files that he needs on his account and the same thing should apply for other users on their accounts..They should only see files and folders that are relevant to them.
Which program can I get to ensure I achieve this?
recommendations on a hardware/software inventory tool that comes with an agent.I manage a windows network of about 150 machines and would like to be able to install the agent on each machine and then get an overview of all the machines on the network with list all their installed hardware and software. Also we have laptops that leave the network. I would like them to "phone home" once in a while to check in.The reason I'm looking for an agent vs agent-less is I don't want to have to poke hole in the local firewalls or have to configure remote access per machine. Just looking to deploy the agent. Spiceworks almost does all this but doesn't have a stable agent yet as far as I know.

View 2 Replies View RelatedI own a Dell XPS M1330 laptop (Windows 7 Home Premium 32 bit, service pack 1) that is about three and a half years old. I realize this Dell model has been discontinued. Work with me here. I STRONGLY believe after 6+ hours of personal troubleshooting that the laptop model is NOT the problem. I have lived at the same apartment complex the entire time I have owned this laptop. Up until a month ago when a new management company (the third one I’ve had) took over, I was able to use the free WiFi they offer at the office and the laundry room without one single speck of a problem weekly for YEARS. Suddenly I am getting: Unidentified Network: No Internet Connection with a public park bench (which it is a public network, I suppose) and a “!” over my perfect five bar signal. Therefore, we can rule out signal strength as the problem. I have a Dell Wireless 1395 WLAN Mino-Card, the card that came pre-installed with the laptop when I bought it brand new. Also, I know the Dell Wireless Card WLAN Utility is installed on this computer but I’ve always used Windows Network and Sharing Center to control the WiFi network I am connected to. I saw something somewhere about this maybe being the problem but since I’ve never used it I don’t think it has anything to do with my problem…
Talk about the router will be brief as it is my apartment complex they will not allow me access to the router so I know virtually nothing other than it is a Cisco wireless router, there are three office computers connected to it that run the internet just fine, and DCHP is enabled on both my laptop and the router (I may or may not have snuck in against their wishes to figure this one out…).
Also noteworthy are two things. One: I can connect to about a dozen other public WiFi networks around the city malls, coffee shops, bookstores, the college campuses, ECT. So connecting to WiFi is not the problem, this WiFi network specifically is (AKA. My NIC is NOT dead). I can also connect to my boyfriend’s private network at his house. The second thing worth noting is that once, I got the manager to cave and re-set the router for me. It connected! I re-started my computer and it still connected! I took my laptop back to my apartment, brought it back re-booted an hour late and it still connected! The next morning; back to the same old annoying problem. I asked him if they did ANYTHING with the computers at night and he said no.
As I stated, I have 6+ hours of troubleshooting pre-done on this problem. I have tried what I am able to with no access to the router (okay, maybe I snuck in and did a couple more things…) including:
Re-start laptop.
Re-start router.
Disable all firewalls/virus protection programs/ect.
Connect to the internet in Safe Mode.
Disable Bonjour.
Uninstall wireless card/re-install wireless card/un-install drivers/re-install drivers/update drivers.
Reset the TCP/IP stack.

my customer has FreeRadius, and I'm trying to get the server to assign a network admin role to a 5K running 5.0.3 code.This is based on the example given in this document: url...The server authenticates the user name, but will only put the user into the network operator role. This is confirmed by checking the output of show user-account and debug security user-db.The Radius test using the same credentials passes the authentication test. I'm sure the problem is that the N5K dosent understand the VSA format of the attribute, and that this is a simple syntax problem.
