I live in a shared flat. And all 20 rooms are connected to this switch I believe. Is there any method to prevent the landlord/tech guy monitoring our internet activity (e.g. bandwidith activity, websites we looked at, etc.

View 1 Replies View RelatedMy wife is moving into an apartment complex for school and she has a Brother HL-2270DW printer. Since she only has a laptop and moves around the apartment, I would like to use the wireless on the printer. Unfortunately, the internet for the building is just through wireless APs. I have the printer installed on the network, but my concern is that anyone can just search for network printers and install it. While printing on it won't be useful for them, it could be a good way to waste her paper/toner. Is there a way to prevent users from installing it without being able to change the router settings? I did not see any option in the web configuration.
View 3 Replies View RelatedMy IPTV connection works fine so far but as soon as I start watching TV I can't use my WiFi connection anymore. My router is an "Alice Modem 1121" (SIEMENS S1621-Z220-A) with 4 LAN ports and a WiFi interface (4th LAN port provides the IPTV). It is directly connected by wire to my PC's ethernet card for the IPTV and the internet is provided via the WiFi. When I activate the LAN connection the WiFi and internet connction stays up and requests can be sent but nothing returns anymore. Another device (iPod) has no problems with accessing the internet while IPTV is in use. I also have a Netgear WNR1000v3 router which I tried to use as AP instead but it's exactly the same problem. Unlucky the Netgear router is not supported to use dd-wrt firmware yet (I've found a step by step guide to prevent multicast floods with dd-wrt/ebtables). But maybe the Alice Modem can handle this problem on its own. I read some stuff about VLANs and splitting them but I have no clue how that would look like.
The "nas_0_1_34" is for the IPTV.
i just need to know is is there any way to prevent network from MACflap.The best way will be when switch will disable the interface where the macflap was detected.I need to set this security feature on 2960s.

View 3 Replies View RelatedAnu network monitoring software that would monitors constant network connectivity? I am working with a company who uses an Access database that checks members in and out of a gym. 6-8 people work in the database at any given time. Several times a day the users will get a network error and they have to force the database to close. Sometimes this happens to all of the users and sometimes to just certain ones. I believe the problem lies with the database (due to poor programming) but I want to monitor the network connectivity to see if and when the network connection is dropped and determine if that corresponds with when users begin seeing network errors in the database.

View 3 Replies View RelatedI have a questions about protecting my network. My parent's have rented out my room, since I'm going to college, and I was wondering if there was a way to monitor the traffic that is going on in my network. Once the guy moved in, the wireless connection speed drastically decreased. I was barely able to sure the internet on my laptop. I currently have about 8 devices connected to my network. I am running a wired connection for my desktop so I don't feel any lag, but everything else runs on wifi.
View 1 Replies View RelatedI was wondering if there is a way to monitor the total bandwidth available at any given time? My ISP claims and is charging me for a certain amount of bandwidth but I suspect that during the day I am getting much less.
I would like to track available bandwidth continuously (or every 5, 10, 15 minutes) and log that data so I can show them the results. I'm on a Mac 10.7 but can use Windows XP also.
My ISP provide me with Thomson TG799vn (Gateway). The modem can be used with LAN cable and wifi function on it too.
The only computer that's directly connected to it is mine and I am currently using Ubuntu Oneiric and Windows 7. Is there anyway that I could monitor user (disconnect / ban any unwanted connection) connected to my modem.
From the gateway page I can see the below info but do not know how to use it :

View 4 Replies View RelatedI need to track and record all functionality, connectivity speeds and applications of a remote laptop. Here's the basic set up of my problem:We have 40 medical facilities in five Western States, each with up to 30+ pieces of hardware including thin clients, PCs, laptop computers and wall mounted touch screen kiosks operating on a variety of OS including primarily XP pro, then Linux and transitioning into Win 7.We have installed Aruba wireless network in each building on which our mobile medical cart laptops connect. Each facility has a different mix of primary and backup/failover ISP from DSL, Cable, T1 to Bonded T. All are at or exceed 22MB down, 5MB up save the T1s at their dedicated 1.5 and we monitor speeds and network stats trhough our gateway device. PfSense.All employees connect through an RDP (Remote Connection) to our hosting company in Atlanta, GA where the farm of about 28 servers reside hosting our medical, email and office applications.We regularly are contacted by nursing and clinical office staff complaining that "the network is slow". We review connection speeds, loads, ping times and confirm that there are no ISP Speed issues that are causing the "Slowness". However when we review exactly what the nurses mean by "slow" it invariably turns to how long it takes to log in to the RDP sessions and access then run their medical applications in the RDP. They often sit and wait for the RDP to load for five minutes or more and complain of waiting for their typing to catch up in the applications they work in.
We believe the slowness occurs once they are connected in the RDP and that their problems are occurring at the hosting company's facility, getting through their firewall, through profile management and server hardware/software but we can not prove this is the case because the hosting company always claims they see perfectly acceptable speeds and access on their side and we are locked out from access to monitor tehir environment. Changing hosting companies is probelmatic because they are specialised in our industry and leaving would be diffcult. I need some software that I can install on a few machines in a select few of our facilities that will track and record the actual user experience so that we can watch and review exactly what is happening, what the network stats look like and precisely where the user is experiencing "slowness".
Is there any way to hide my activity on the network? My network administrator monitors our network activity, specifically chat.

View 4 Replies View RelatedWe currently have a 3/3 Etherloop. We dont have any internal IT as we are still small and while not a networking guy I can at least understand what is going on. Right now at peaks we are hitting 100% utilization.
We run a call center in house so I am trying to determine at the very least how much of this traffic is from voice data compared to everything else.Was running through our networking configuration and it just seems off to me. The following is the flow.
-Etherloop Demarcation >
-Cisco Integrated Access Device >
-D-Link DIR 655 Wireless Router >
-24port HP Procurve switch >
-24port HP Procruve switch >
Everything up to the first switch is a single line. The first switch has all ports running out except 1 which goes to the second switch. The second switch runs out to machines as well.
I am at the networking level where I understand a switch but have no idea what the IAD really does between the etherloop modem and the wireless router.
For some reason I feel like the router should not be setup in that manner and should be off of the switch. With the cisco IAD running directly to the first switch. So my 2 big questions are.
1. Does this setup even make sense.
2. Whats the easiest way to monitor traffic, at the very least it would be nice to see real time up/down and be able to log in. Then I guess using ports figure out what is being used by voice. My first guess was just putting a machine between the IAD and first switch and monitor and log the traffic.
1) How do you manage your inventory of network equipment from the time you receive a product into inventory to the time you decommission it?
2) How do you make aware the people who manage your network monitoring/reporting software that a device has been added/removed from the field?
2a) How do you notify the people who manage your network monitoring/reporting software of what is to be monitored on a new device in the field? Of a new interface that has been added/removed on an existing device?
2b) How quickly do you notify for 2/2a? i.e. minutes, hours, days, etc.
3) What types of interfaces and resources do you monitor on a network device?

View 5 Replies View RelatedWe have 9 WLCs around a corporate network. Each of the WLCs was in the same mobility group for failover purposes, and to permit APs to reconnect back to their primary WLC in the event of a failover.
However one of the sites has now been sold and pending separation of the LAN infrastructure the APs need to be isolated and prevented from associating with any WLC other than their primary (on site). From our experience once the APs know about other WLCs they retain this list in NVRAM even if the secondary WLC is removed from the configuration they will still associate with one of the known APs if possible (Cisco document this). WLC v 8.1.185.
I often have to change switch ports to different VLANs. Regardless of whether I find the ports myself or if someone tells me what the ports are, I'll always perform additional verification steps to make sure that the port I'm changing doesn't connect to a switch, a router, a server, or something else that's equally important. But mistakes happen, and I have accidentally changed the wrong port to a different VLAN, thereby disconnecting the end node.
Is there a way to configure a port so that it will not allow you to change its VLAN (or make any configuration changes to it)? I'm imaging a command that when applied to a port would not allow you to make config changes to the port until you remove that command from that port, at which point you'll be able to change its VLAN, shut it, etc. If there isn't such capability, what strategy do you use to minimize the possibility of accidentally changing trunks, routed ports, or important access ports to different VLANs (other than labeling and verify)?
I've tried a few things to get around this, some kids where I work keep changing the wallpaper, sometimes to quite disgusting things. Since groups of them all use the same login with roaming profiles, everyone gets to look and laugh at the annoying wallpaper.
I've tried enabling active desktop local policy and preventing users changing wallpaper but as far as I could tell active desktop didn't even come on, I refereshed the policy.
Does anyone know a good efficient way of simply setting a wallpaper for all users in an ad ou and preventing them changing it? I've got rid of all ways to set a desktop wallpaper apart from the right click menu on an image which has the "set as backgound" option, that's what they are using to do it.
I don't really mind how it's done, could be a registry hack to remove that option from the right click context menu when clicking on an image, I could then deploy it with group policy.
