The sqm-scripts traffic shaper
This repository contains the sqm-scripts traffic shaper from the CeroWrt project. See: http://www.bufferbloat.net/projects/cerowrt/wiki/Smart_Queue_Management
sudo make install should install things on a regular Linux box. For
OpenWrt, there are packages available in the ceropackages repository:
https://github.com/dtaht/ceropackages-3.10 and in openwrt nightly
"Installing" the current development version from git
Run the steps below on your own computer (not on the router) to retrieve the newest script version from this repository, create the scripts, then copy those new scripts to your router.
Make a local clone of the git repository (if you have not already):
git clone https://github.com/tohojo/sqm-scripts
Change into the new directory:
Make sure the source is updated:
Create the scripts for your platform (PLATFORM is either linux or openwrt) and output them to a local
make install PLATFORM=openwrt DESTDIR=./current_sqm_base
Optional for OpenWrt: The final step will overwrite your router's current sqm configuration file (at
/etc/config/sqm). If you want to preserve the current configuration, delete the newly created config file from the local
rm -r etc/config
Now, use scp to copy the new scripts to the router. Change
$YOUR.SQM.HOSTNAMEto the address/DNS name for your computer - probably
192.168.1.1or on cerowrt
gw.hom.lan. If your account on the router is not "root", change "root" to your account:
scp -r ./* root@$YOUR.SQM.HOSTNAME:/
Note this method relies on the presence of the required qdiscs on the router/destination host. On openwrt, you should first install the "normal" sqm-scripts package to take care of all the dependencies, then use this procedure to update to the newest sqm-scripts.
SQM_VERBOSITY_MAX controls the verbosity of sqm's output to the shell and syslog (0: no logging; 8: full debug output).
SQM_DEBUG controls whether sqm will log all binary invocations, their output and its shell output into a log file in
The log files are named
Log only the binary invocations and their output:
/etc/init.d/sqm stop ; SQM_DEBUG=1 SQM_VERBOSITY_MAX=0 /etc/init.d/sqm start
Log verbose debug output and all the binary invocations and their output:
/etc/init.d/sqm stop ; SQM_DEBUG=1 SQM_VERBOSITY_MAX=8 /etc/init.d/sqm start
Log both start and stop:
SQM_DEBUG=1 SQM_VERBOSITY_MAX=8 /etc/init.d/sqm stop ; SQM_DEBUG=1 SQM_VERBOSITY_MAX=8 /etc/init.d/sqm start
Note: This always appends to the log file(s). If you just run a one-off command with debugging enabled from the command line this is fine, but if you enable debugging in the web interface, the files can grow too large and cause problems. So if you do enable debugging in the web interface, remember to turn it back off again.
