How to cross check your ISP charges your Internet usage fairly


I personally use NetWorx. Witch is a free and simple, yet powerful tool that helps you objectively evaluate your bandwidth situation. You can use it to collect bandwidth usage data and measure the speed of your Internet or any other network connection. NetWorx can help you identify possible sources of network problems, ensure that you do not exceed the bandwidth limits specified by your ISP, or track down suspicious network activity characteristic of Trojan horses and hacker attacks.
The program allows you to monitor all your network connections or a specific network connection (such as Ethernet or PPP) only. The software also features a system of highly customizable visual and sound alerts. You can set it up to alert you when the network connection is down or when some suspicious activity, such as unusually heavy data flow, occurs. It can also automatically disconnect all dial-up connections and shut down the system.
The incoming and outgoing traffic is represented on a line chart and logged to a file, so that you can always view statistics about your daily, weekly and monthly bandwidth usage and dial-up duration. The reports can be exported to a variety of formats, such as HTML, MS Word and Excel, for further analysis.
With NetWorx you can
• Find out and monitor how fast your Internet connection is.
• Find out and monitor how much Internet traffic you consume.
• Verify whether your ISP charges your Internet usage fairly.
• Detect a suspicious network activity on your computer.
• Perform simple network tests such as ping and trace route.
• Be notified about excessive Internet usage

You can download it from here.

Hi, I am unable to generate a ping test with windows 7. I have followed the answer already posted


Network administration is a serious job. This is especially true for companies that rely on computers to input, process and share data. The more computers or nodes in the network, the harder it gets to manage them. Fortunately, there are several tools can greatly simplify your job. They are called network monitoring tools. Many of them are open-source programs, and they are ready for download and installation.

Don't mistake these programs as simple tools for just monitoring if a device is turned on or off. They are full-pledged remote access programs that allow an administrator to view all devices that are connected to the network (routers, modems, servers, printers etc.) and all the processes being run in each node. If you are a network administrator, you'll need specific programs for different jobs.

Network Monitoring Utilities

Network Ping and Softperfect Network Scanner are the tools for the job. Network Ping gives you a visual overview of all the computers connected to your network. It checks the network status by sending each device a ping. If the device is down an email alert can be sent to an administrator.

Softperfect Network Scanner or NetScan is popular lightweight software that detects all devices attached to your router or access point. It pings all possible IP addresses to determine which computers are currently being used. It is also integrated into the Windows Explorer, allowing you to view all shared files and folders through the NetScan interface.

Intrusion Prevention System (IPS)

The most popular IPS worldwide is Snort. In real time, it analyzes packet capturing and network traffic on IP networks. With its analysis of protocols, Snort can identify network attacks and attempts to perform unauthorized actions such as fingerprinting, buffer overflows and port scanning. With this software running, you are guaranteed that your office network is safe from intrusions. Snort can record packets and generate human-readable reports.

Remote PC and Server Management

Putty and the "Dude" are network monitoring programs for the Windows platform. They track all devices in your network and they can generate a network map or inventory depending on the nodes currently online. Putty, in particular, is very light at 450 kb because of its UNIX-based interface. It allows you to set administrator privileges in remotely controlling computers. Putty can also manage bandwidth allocation or block IPs from using DSL internet.

Having the right network monitoring tools for the job helps network administrators automate many of the day to day operations that take up time and resources to complete.

Can i use the dv port on my monitor to display a movie on a led tv? i bought a dvi to hdmi adapter and plugged into my monitor dv port and the hdmi cable into my hdmi port on my tv and i'm getting nothing...


Ports on the monitor are for receiving the signals from the sources, not for sending signals out to another devices.
Your TV HDMI should be connected directly to the video source output, not through the monitor.

The Cisco 7940 Phone...if you work from home and use this phone can your Corp office be able to monitor your calls?


It is possible for them to monitor voip calls, if your call passes through their network, or they do remote monitoring on network traffic. The voip traffic is only data that needs to be 'reassembled' to hear the voice stream. However, this is more difficult if the traffic is encrypted between the phone and the call manager or whatever they are using.

I am no legal person, but I am sure that you would have to have agreed to have your calls monitored for them to be able to do this.

I can not log onto my dell powerconnect 2708. I'm connecting the dell powerconnect 2708 into a hughes net modem and routing to three different locations. I would like to monitor/contol usage...


The problem you have is unlikely to be related to your server but to the modem and any ISP restrictions placed on your service i.e. it may block remote access or any port 80 traffic not originating from within your LAN. I don’t know much about your situation but it may be worth contacting your ISP to see if the functions you require are available with your hardware and contract type. Attached is a link that may help.

Program that is like ultra surf or hotspot shield?


Spend a couple of bucks and get something that works. See the link below.

In addition, the free stuff monitors your traffic for marketing and who knows what other purposes. Isn't the whole reason you want a VPN in the first place to keep people from looking at your traffic? Source(s): http://www.personalvpn.org
