[LARTC] tc save restore QoS options

[LARTC] tc save restore QoS options

[Tester]

Hi there.

I got another problem now.
I got a linux router with 4 network interfaces on whose i do traffic shaping 
with tc tool.
I'm constantly changing classes, filters and such. The need to constantly 
change them will remain even after i finish testing all posibilities.
All works fine until the router doesn't get rebooted when i loose all my tc 
settings. After it comes back i have to make all the changes again and it's 
REALLY annoying to do so. (You try to reconstruct 50 or more lines of 
commands in the specific order ;-) )

A simular problem i encontered with iptables, but I solved it with crontab and 
iptables-save/restore.
Is there a simular solution for tc?
How do you cope with this problem?

One option would be to have a script and constantly change what i do with tc 
in it to so after a reboot it would come back. But his way i would constantly 
have to worry about sychronizing the script with the actual changes i make 
and double my efforts.

Please help me.

Have a nice day.
-Tester

No.

Scripting.

I don't have a real solution.  I have a perl script that can discover a htb 
setup.  That can be used to recontruct the commands.
But why don't you create a script that you each adapt and execute?  So you can 
rerun it if your box reboots.

This might help. 
ftp://k12linux/pub/tc/tc_gen.tar.gz
Put it in it's own directory to untar.
 
A script generator based on htb with easy to tweak config files.

I use it on dual redundant bridges that use spanning tree to block one
box. 
You can also use it to generate a rule set for iptables, which I will be
doing this summer.

URL is broken, hostname is broken. Looks like you have an internal hostname 
there.
