The Wonder Shaper 1.4.1 ============== Copyright ------------- Copyright (c) 2002-2020 Bert Hubert , Jacco Geul , Simon Séhier , See the ChangeLog for information on the individual contributions of the authors. About -------------- Wonder Shaper is a script that allows the user to limit the bandwidth of one or more network adapters. It does so by using iproute's tc command, but greatly simplifies its operation. Wonder Shaper was first released by Bert Hubert in 2002, but the original version lacked a command-line interface, from on version 1.2 this feature was added. From version 1.3, the HTB queuing is used instead of CBQ, allowing better bandwidth management on high speed (above ten megabits) links. In version 1.4 an improved ingress shaping method was implemented and the ability to limit either down or up (both is still possible too). The original README is a rather lengthy document and is saved under README.bhubert, for those who'd like some more background information. Except any notes on operation this document is considered up-to-date. Installation -------------- ### Obtaining wondershaper It is recommended to clone the GitHub repository of wondershaper such that you can pull in new updates at any time (if available). Open a new terminal and clone the repository using git clone https://github.com/magnific0/wondershaper.git This will clone wondershaper in your current folder in a new folder named wondershaper. Now enter the folder using cd wondershaper ### Using wondershaper You can run wondershaper (as any user with sufficient permissions) without installation and stop following the instructions at this point. Show the wondershaper usage instructions by typing ./wondershaper -h The program details all available options on how to use wondershaper. Next is to pick an interface that you want to shape. You can see all available interfaces by typing ip addr show Note that on older systems this command might not be available. In this case you should run ```ifconfig``` instead. Identify the network interface that you want to shape. The names [differ per system](https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/). In the following example a wireless interface is limited to an [upload of 4Mbps and download of 8Mbps](http://whatsabyte.com/). ./wondershaper -a wlp4s0 -u 4096 -d 8192 If you get messages telling you that ```RTNETLINK answers: Operation not permitted``` your user account does not have sufficient privileges. In that case try: sudo ./wondershaper -a wlp4s0 -u 4096 -d 8192 ### System installation (optional) A makefile file provided for easy installation. The default location for wondershaper is in ```/usr/bin```. If you want to install to your system you can run: sudo make install You can verify that wondershaper was installed correctly by entering: which wondershaper This should return ```/usr/bin/wondershaper```. You can follow the same instructions as explained in the "Using wondershaper" section, but instead of running the local version of the program you now run the system version by removing the ```./``` from the beginning of each command. For example to show the help instructions again run: wondershaper -h ### Persistent usage of wondershaper (optional) Instead of using the commandline options to set the rates and interface as previously shown, it is necessary to set these parameters in the ```wondershaper.conf``` configuration file. You can edit this file using your favourite text editor (vim in the example below) as such: sudo vim /etc/systemd/wondershaper.conf To make sure wondershaper is reactivated on reboot a systemd service file is provided. First enable wondershaper as a systemd service using: sudo systemctl enable --now wondershaper.service This way wondershaper is activated with your setting upon reboot. Usage -------------- wondershaper [-hcs] [-a ] [-d ] [-u ] The following command line options are allowed: - `-h` Display help - `-a ` Set the adapter - `-d ` Set maximum download rate (in Kbps) and/or - `-u ` Set maximum upload rate (in Kbps) - `-p` Use the presets in /etc/systemd/wondershaper.conf - `-f ` Use alternative preset file - `-c` Clear the limits from adapter - `-s` Show the current status of adapter The different modes are: wondershaper -a -d -u wondershaper -c -a wondershaper -s -a Some examples: wondershaper -a eth0 -d 1024 -u 512 wondershaper -a eth1 -d 94000 -u 94000 # could be used on a 100Mbps link wondershaper -a eth1 -u 94000 # only limit upload wondershaper -c -a eth0 wondershaper -p -f foo.conf
