Typo on line #430, 168/128

Anonymous — Sun, 27 Aug 2006 15:55:12 -0000

Line 430 says:
# RULE=192.128.1.0/24
This would work, as it is a valid block, except a few
lines down it refers to this rule, "The configuration
says ... the traffic going to network 192.168.1.0 will
be ..."

RTNETLINK answers: No such file or directory

kempston — Wed, 06 Apr 2005 22:46:09 -0000

When i do
debian:~# /etc/init.d/shaper restart

i get
Stopping CBQ traffic shaping: shaper.
Starting CBQ traffic shaping: RTNETLINK answers: No
such file or directory
shaper.

After 2 days of digging i figured that it's normal, and that
/var/cache/shaper/cbq.init
should have
2>/dev/null
after
/sbin/tc qdisc del dev eth0 root
but for some reason it didn't

I checked /etc/init.d/shaper and found out, that it does
have
2>/dev/null
after
tc qdisc del dev $1 root

then i realized that it works only when it code get's
executed it and does not work when code get's printed to
cache, couse 2>/dev/null goes to echo of code not to the
code itself.

It starts working if you change 2>/dev/null to '2>/dev/null'
but for the same time it will put erros when code is
executed so basicly i suggest following patching

--------------------
### EXEC Remove root class from device $1
cbq_device_off () {
tc qdisc del dev $1 root 2>/dev/null
} # cbq_device_off

### Remove CBQ from all devices
cbq_off () {
for dev in `cbq_device_list`; do
cbq_device_off $dev
done
} # cbq_off
--------------------
SHOULD BE REPLACED WITH
--------------------
### Remove root class from device $1
cbq_device_off () {
tc qdisc del dev $1 root '2>/dev/null'
} # cbq_device_off

### EXEC Remove root class from device $1
exec_cbq_device_off () {
tc qdisc del dev $1 root 2>/dev/null
} # cbq_device_off

### Remove CBQ from all devices
cbq_off () {
for dev in `cbq_device_list`; do
exec_cbq_device_off $dev
done
} # cbq_off

speed

Anonymous — Wed, 02 Mar 2005 18:03:57 -0000

Please explain me this:
I have an ordinary config file, but there are about 4000
lines with RULE=
it looks like
DEVICE=eth0,100Mbit,10Mbit
RATE=128Kbit
WEIGHT=12Kbit
PRIO=5

RULE=62.175.80.0/20,192.168.0.70
RULE=62.198.128.0/20,192.168.0.70
........
And there are a lot of RULE=.... :)
So, when the shaper is up, i have only about 1.8
megabytes/sec.
When i turn off cbqinit, speed gets up to 9-9.5 meg/sec.
What should i fix, to have a full speed without lost???
P.S. Sorry for my bad Enlish :)

[UNKNOWN] in kernel 2.6.X

Anonymous — Wed, 28 Jul 2004 17:57:17 -0000

Hi...

I cant make CBQ to work on kernel 2.6.7 and some
previous... When I run "cbq stats" I'm getting the
following:

class tbf 2022:1 parent 2022: [UNKNOWN]
class tbf 2021:1 parent 2021: [UNKNOWN]
class tbf 2020:1 parent 2020: [UNKNOWN]
class tbf 2019:1 parent 2019: [UNKNOWN]
class tbf 2018:1 parent 2018: [UNKNOWN]
class tbf 2017:1 parent 2017: [UNKNOWN]

Any tips?

Doesn't accept "long" masks for IPs in RULE

JCCyC — Tue, 20 Apr 2004 01:25:36 -0000

Won't accept something like

RULE=10.0.1.128/255.255.255.240

Instead it has to be

RULE=10.0.1.128/28

Could the RULE parser be enhanced to accept the "long"
form too, so every form of netmasks in existence could
be auto-fed into class files?

2.4.25 - VLAN + CBQ Broken ?

Anonymous — Tue, 23 Mar 2004 00:07:19 -0000

gf.dellicarri@itgate.it

Seems that Kernel 2.4.25 + VLAN + CBQ doesn't work.
Just after:
/sbin/tc qdisc del dev eth1.10 root
/sbin/tc qdisc add dev eth1.10 root handle 1 cbq
bandwidth 100Mbit avpkt 1000 cell 8
/sbin/tc class change dev eth1.10 root cbq weight
10Mbit allot 1514
no more traffic can pass on eth1.10 VALN if.
Else if you load CBQ modules (sch_tbf, sch_cbq, etc)
then start zebra/quagga daemons (ospfd, bgpd) they'll
burn all your CPU time.
You must unload the modules to work.

Any ideas ?

timecheck not run in ASPLinux 9.x

Anonymous — Thu, 18 Mar 2004 00:35:45 -0000

"service cbq timecheck" do nothing in ASPLinux 9.x (checked 9.0 and
9.2)
ASPLinux 7.x (7.1, 7.2, 7.3) - OK.

Probably it because of that command "tc class show dev eth0" show
nothing in ASP 9.x
In ASP 7.x this command works correctly

Because of what it can be? How to force to work??
