The latest version of smeserver-qos is available in the SME repository, click on the version number(s) for more information.



smeserver-qos is a tool based on the script wondershaper to give quality of service (Q.O.S) on your network.


You need the firewall-service repo to install this contribs and your server must to be set in a "server and gateway" mode with two network cards.

Installation 8.x and 9.x

This contrib is currently held in the fws repository, so the following commands will install on your smeserver.

yum install --enablerepo=fws smeserver-qos

You will then need to activate the database changes etc. The 'official' way is to perform

signal-event post-upgrade;  signal-event reboot

Then you can go to the server-manager panel "quality of service" and perform settings.


yum remove smeserver-qos
signal-event post-upgrade;  signal-event reboot
