Shaping script wondershaper seems FUBAR

I downloaded wondershaper from the Devuan repos to see if I could shape the bandwidth on my Devuan Linux box since our ISP connection is rather anemic. When I ran it I got some unexpected output:

[ROOT@devuan-nuc ~] # wondershaper eth0 20000 5000

I attempted to contact the author using the e-mail provided in the /usr/share/doc/wondershaper/README.Debian.gz file. Sadly that bounced as

550 Unrouteable address

Is anyone here able to assist with debugging this sh script and making it work? I am not familiar enough with tc to do it myself yet.

Re: Shaping script wondershaper seems FUBAR

Did you install it? It does depend on iproute2 (or iproute)

And then if this is ceres rather than daedalus anything (else) is possible

Re: Shaping script wondershaper seems FUBAR

Yes, wondershaper was installed with apt install at the CLI.  Also, iproute2 is installed.

[ROOT@devuan-nuc ~] # apt search iproute
Sorting... Done
Full Text Search... Done
...
iproute2/oldstable,now 5.10.0-4 amd64 [installed]
  networking and traffic control tools
...

I am running:

[ROOT@devuan-nuc ~] # grep -i pretty /etc/os-release 
PRETTY_NAME="Devuan GNU/Linux 4 (chimaera)"

Re: Shaping script wondershaper seems FUBAR

ok
peculiar; the script worked fine for me on daedalus; it's the same package version and script.
Which kernel version? And what do you get from:

# tc qdisc show

Re: Shaping script wondershaper seems FUBAR

Running shellcheck against wondershaper would be a reasonable start if it's a shell script.

Then try adding set -x as the second line and see if that tells you what it's trying to do when it fails.

But I'm only guessing because I don't have wondershaper installed.

Re: Shaping script wondershaper seems FUBAR

Current kernel version:

[ROOT@devuan-nuc ~] # uname -v
#1 SMP Debian 5.10.216-1 (2024-05-03)

Yeah, I'll work on debugging the script with shellcheck and set -x. I was hoping to get in touch with the script author and was also hoping he is on here and would respond. Silly of me, I know.

Re: Shaping script wondershaper seems FUBAR

Have you made sure the kernel modules are available (like sch_cbq, sch_sfq and sch_ingress)? Or maybe it's a udev issue, and the modules need to be loaded manually?

Re: Shaping script wondershaper seems FUBAR

I see sch_ingress, but not the other two. Odd.

[ROOT@devuan-nuc ~] # lsmod|grep sch
sch_ingress            16384  0

At this point I am considering just trying to learn about and grok tc. I am going to look for a tutorial on it. Suggestions for a written tutorial are welcome. I will look at videos, but I don't really learn from them.

Re: Shaping script wondershaper seems FUBAR

The traffic shaping uses cbp and sfq (which are the queue types used) so you'll need the modules.
