[Cerowrt-devel] sqm-scripts for debian/ubuntu

[William Katsak]

Hello all,

Before I take the time to set something up, does anyone already have a 
nice wrapper for sqm-scripts on debian/ubuntu (or really any non-openwrt 
distro)? I've already gotten them to work, but want to do something 
"nice" so they run automagically.

Thanks,
Bill

My plan, such as it was, was to have a /etc/sqm dir with each device named there
explicitly (e.g.) eth0.conf, br0.conf, etc.

and in there have the configuration variables currently set by run.sh
in /usr/lib/sqm (or in the
openwrt sqm config file) in shell syntax.

then have a sqm script in /etc/network/if-pre-up.d and if-post-down.d
source those, then run the right qos script from that.

I have never got around to it. And I'm not sure if that is the right
thing for NetworkManager.

Well, I wouldn't mind a world where classification was preserved e2e,
but that is
generally not the case.

I can imagine a few use cases for trying to not squash ingress,
notably where you
would be rate limiting a device inside the home behind, say, a homeplug.

another item that is wrong is that the INSMOD variable should be
mapped to modprobe in
debian systems, and there may be other modules that need to be probed.
(ifb?). I've not come up with a way to reliably detect if you are on
openwrt however....

Aside from that I pretty regularly use sqm thusly on ubuntu...

UPLINK=10000 DOWNLINK=40000 QDISC=fq_codel /usr/lib/sqm/simple.qos

but, yea, it would be nice to have a version that abstracted out to
debian mo better. A concern was whether we could interface with common
firewall scripts in that world (ufw, shorewall)....

Well, push your patches somewhere... having a .deb and/or .rpm
installable package
would be good in the end.

debloat is not needed on a modern debian/ubuntu. Of course, everyone
should be putting something like this, also, at this point, in
/etc/sysctl.conf or in a file in /etc/sysctl.d/ with:

net.ipv4.tcp_ecn=1
net.core.default_qdisc=fq_codel
