Free speed limit software for linux

Speed is a simple program to add a transfer meter to any console or terminal based copy program.
Speed allows you to easily report Kilobytes or Megabytes per second when using programs that do not report file transfer speeds (such as cp or ftp).
Usage:
./speed [ -u interval ] -f filename
./speed [ -u interval ] -- < copy_program > [args] /path/to/file /destination/file
< copy_program > is the program we should use to copy the file
[args] options arguments to < copy_program >
Enhancements:
- A progress bar has been added.
- The last argument to cp can be either a file or directory.

cpulimit is a simple program that attempts to limit the cpu usage of a process (expressed in percentage, not in cpu time). This is useful to control batch jobs, when you dont want they eat too much cpu.

cpulimit project does not act on the nice value or other scheduling priority stuff, but on the real cpu usage. Also, it is able to adapt itself to the overall system load, dynamically and quickly.

keyspeedapplet project is a panel applet to show the speed you are typing.

This is an Applet, similar to the applets, showing the cpu-speed, which shows the speed you are currently typing.

It shows the average speed of the last 15 seconds and the average speed of the last minute.

In addition it shows how many errors you made and features a highscore list which is stored human readable in ~/.keyspeedrc.yaml

Azureus Speed Control is a project that enables automatic configuration of your upload limit. This addresses the problem of implicit additional upload when Azureus downloads with high speed, which can lead to connection choking. This is a problem specially for users with low upload bandwidth like German ADSL users.

If your download rate increases, the upload limit will be reduced by a value that can be customized. If the download rate decreases, the upload limit will increase again.

mod_limitipconn is an Apache module which allows web server administrators to limit the number of simultaneous downloads permitted from a single IP address.

I have ported the original mod_limitipconn module to Apache 2.0. The Apache 2.0 port includes all the features of the Apache 1.3 version, including proxy tracking and MIME type inclusion/exclusion.

PipeBandwidth is a program that measures the speed at which data goes through a pipe and prints statistics to stderr.

Basically, it just reads from stdin, writes data back to stdout, and measures the speed. PipeBandwidth can be useful to measure transfer rates while sending data through netcat or compressing with gzip or bzip2.

The SFSU Penaltybox is a solution for high network traffic in residence halls. It implements a bandwidth quota, penalizing the users who cause most of the network congestion.

When users go over their bandwidth quota in a time period their traffic is limited using a Packeteer PacketShaper for a certain period of time before they are let out from the penalty box.

The users will be blocked immediatly when they exceed their limit, and they will be blocked from that point on for how ever long you set your time period. (eg we have a 10 gb/week limit, so if they go over on day 3, they will be limited to 64kbps until day 10, they will be blocked for an entire week after they have exceed their limit).

CPEXIF project utility copies EXIF data from a NEF (Nikon RAW file) or a JPEG file to a JPEG file.
The CPEXIF program is free software released under the terms of the GNU General Public License. There is no warranty, use it at your own risk.
CPEXIF is a command line utility.
Usage:
NEF to JPEG copy mode
The usage is:
cpexif [options] source.nef destination.jpg
available options are:
--nomakernote
--noisofix
In this mode CPEXIF copies the EXIF data from the source NEF file (Nikon RAW file) to the destination JPEG file. Thumbnails are not copied.
The --nomakernote option instructs the program to strip the MakerNote field from the EXIF data. This reduces the EXIF data size, in many cases substantially. It is intended to overcome the 64kB limit. Some information about the equipment and the picture will be lost when you use this option.
Many Nikon cameras store the ISO Speed value in a non-standard way. By default, CPEXIF fixes it by adding the missing ISO field. It creates one using the information from the MakerNote field. Most people want this, but if you dont, use the --noisofix option.
JPEG to JPEG copy mode
The syntax is straightforward:
cpexif source.jpg destination.jpg
CPEXIF copies the whole file segment containing the EXIF data without examining it. That explains why data modification cannot be performed (no ISO fix for Nikon users, sorry) and no options are available in this mode. This approach prevents any compatibility problems, so JPEGs from any digital camera can be processed this way.
Enhancements:
- This release fixes JPEG file corruption with EXIF data larger than 64K.
- A new JPEG to JPEG copy mode has been added.
- An automatic fix for the missing standard ISO Speed field has been added in the NEF to JPEG copy mode.
