Thank you! (and a critique request)
Just wanted to send out a quick thank you to all the PF developers. I've just completed a "simple" altq setup on a 3.2 -stable box to cap a user's outgoing bandwidth. Tested with the limited IP, and with an IP in the default class, works great. I'm looking forward to upgrading these boxes later on to 3.3 -release with the new pf-merged altq code. :) I'd like to offer up my altq.conf file for two purposes: 1) so that future users searching the archive might find an easy sample to start from, and 2) for the list folk to critique it for accuracy. With this config, I wanted to limit an individual IP to a portion (15%) of the bandwidth during heavy usage. Everyone else should fall into the default class. ## interface dc1 bandwidth 1M cbq class cbq dc1 root NULL pbandwidth 100 # meta classes class cbq dc1 ctl_class root pbandwidth 4 control class cbq dc1 def_class root borrow pbandwidth 95 default # Allocate bandwidth class cbq dc1 foo_class def_class borrow pbandwidth 15 filter dc1 foo_class 0 0 192.168.0.42 netmask 0x 0 0 filter dc1 foo_class 192.168.0.42 netmask 0x 0 0 0 0 ## Thanks again! -J.

Cranking HZ would help here, but this doesn't seem to work on i386 at least. -d

foo0? damn, my secret diff must have leaked.

well 6k is just a little _too_ low for a 100Mb interface (I presume it is
one). the resolution isn't that high I think.
tho, 10k worked somewhat good for me on a 100Mb card - don't expect a too
close match on such absurd low values, as said, the time resoltion is limited.

we don't have support for the more obscure options in... we're pretty sure
nobody uses them.
which, exactly, do you miss and why? perhaps we really missed something.

ALTQ: resizing buffer sizes of queues?
Hi!
I'm running a box for testing and like to limit outgoing traffic on my
DSL line.
My setup looks like this:
altq on foo0 cbq bandwidth 10Mb queue { std, test}
queue std bandwidth 100% cbq (default borrow)
queue test bandwidth 6Kb cbq (red)
pass out quick on foo0 proto tcp from any to 1.2.3.4 \
keep state queue test
When transfering data to 1.2.3.4 I see burst of around 140kB in tcpdump
and then no traffic for some time.
Overall when transfering the speed won't go below ~35kbyte/s.
I've played around with qlimit and cbrsize but it didn't help.
Is there any way to limit the speed to 6kB/s?
Is there a way to define custom queue sizes with altq/pf just like altq
itself allows?
And last but not least: Is there a altqstat like program?
Thanks, Hendrik
