bandwidth test

bandwidth project is an artificial benchmark for measuring memory bandwidth, useful for identifying a computers weak areas.

It tests several types of memory:

· Main memory read accesses
· Main memory write accesses
· Level 2 cache read accesses
· Level 2 cache write accesses
· Framebuffer read accesses
· Framebuffer write accesses
· String library routines

Whats New in This Release:

· 64-bit support has been added.

A tool for monitoring and warning you of sudden excess bandwidth usage. We built this after a couple of heart attacks, false alarms and big bills incurred by our customers at short notice.

Its main feature is to warn you immediately when a sudden bandwidth spike is detected, by email and SMS. It will also take a sample of the traffic with tcpdump for analysis if the spike stops before you can get to the machine to examine whats going on.

The program is designed to be simple, independent of the host system, and reliable at warning you as insurance against more complicated bandwidth monitoring systems failing-- in the case where a lapse in concentration can cost you thousands of pounds, you may want to consider having more than one bandwidth monitoring scheme in place :-)

Configuring & usage:

You should invoke the program something like this:

/usr/local/bin/bwalarm 2>&1 | logger -t bwalarm

which will send the programs diagnostic output to your system logs in case you dont see the email or SMS. You do look at your logs regularly dont you? :-)

The script is intended to be a stand-alone program which runs forever on a UNIX system. To change its settings you should edit the top of the file which is reasonable well-documented: essentially you point it at sendmail, tcpdump and set the parameters for issuing an alarm.

So thats the maximum number of packets/bytes per minutes/hour/day, and you can set up as many conditions as you want. Finally which email addresses or phone numbers to notify, and your account details at Clickatell, and youre away.

For SMS notification you should sign up with South-African SMS provider Clickatell who are cheap at around £0.03 per message.

While the program is running it logs alerts to stderr but can show you every reading it takes if you invoke it with the --verbose flag. If you use the --test flag, SMS and email sending will be disabled. You can also tell the program to dump its current list of byte,packet counter pairs to stderr by sending it SIGALRM.

Bandwidth Meter and Diagnostics is a Firefox extension that will automatically check whether Internet connection is working or not when a website can not be loaded, and a list of tools for network troubleshooting. Try to type a random domain name(e.g., qwqwqwq121212.com) to see what this means ...

This extension adds "Bandwidth Meter" to the Tools Menu. It performs the following tasks:

· Display your public IP address
· Display your public domain name
· Test download speed/bandwidth
· Test upload speed/bandwidth

This extension runs under any OS. If you use Windows, you could try our other Windows specific extension "Broadband Speed test and Diagnostics" that has extra features and can only run under Windows. We are creating this because we get many requests from non-windows users.

Looking to monitor your bandwidth usage? Bandwidth Vista is modern, informative and intuitive to use. Whether you are looking for network problems or simply want to check the speed of your internet connection Bandwidth Vista is for you. Bandwidth Vista monitors all your connected interfaces at once and holds a history of transfers which can be viewed down to the minute. This dynamic application also indicates the countries of remote computers connected to your machine and maps them for you - quite an eye opener! Also included is a Bandwidth Stop Watch, Email Alerts, an icon for each connected program on your system - with Spyware Squatter!.

Works with Windows XP Home and XP Pro. Requires the .NET Framework 2 installed (available at download page)

Linux Bandwidth Monitor (bwmon) is yet another utility that measures bandwidth utiliazation per interface basis. It is coded in C and takes advantage of POSIX thread and curses library. It runs only on Linux systems since the utility reads /proc/net/dev and /proc/uptime.

The utility reads /proc/net/dev and /proc/uptime files in order to print out bandwidth usage at user selected intervals, maximum bandwidth usage since initialization of the utility and average bandwidth usage since the last reboot. This is done based on network interface.

Tested on Linux 2.2.x, 2.4.x and 2.5.x, SuSE and RedHat distributions.
To compile, simply say
$ make
To install, say (optional)
# make install
Or copy bwmon binary where ever you want.

Bandwidth Meter and Diagnostics description
Bandwidth Meter and Diagnostics is a Firefox add-on that will measure your internet speed Bandwidth Meter and Diagnostics will perform bandwidth and speed measurement for Internet connections so that you always know how fast you really are.

When Firefox fails to load a webpage, the extension will automatically check whether Internet conenction is working or not. You can also use network troubleshooting tools to check the websites. Try to type a non-existent domain name(e.g., qwqwqwq121212.com) to see what this means ...

Here are some key features of "Bandwidth Meter and Diagnostics":

· Display your public IP address
· Display your public domain name
· Test download speed/bandwidth
· Test upload speed/bandwidth


Requirements:

· Firefox: 1.5 2.0.0
