[LARTC] FW: HFSC + ESFQ - class statistics
Hello,
First I want to point out that I’m not so familiar with HFSC, since there
not so much info online.
But here is my script:

The tc show

shown in the period, but the rate is not shown. For the rest of the classes
Sent bytes and packets are shown, but rate is not show here either.
This bug is
related to the kernel or iproute2 package?
Thanks

Re: [LARTC] Leaky bucket in TC
Thank you for your response, My aim is to define a bandwidth (i guess it can be done by defining equal rate and ceil values), and not to allow to pass this value "at any moment" during the connection. Is htb able to do this job, for instance in the simple example below? tc qdisc add dev ath0 root handle 1:0 htb default 15 tc class add dev ath0 parent 1:0 classid 1:1 htb rate 240kbit tc class add dev ath0 parent 1:1 classid 1:5 htb rate 72kbit ceil 72kbit tc class add dev ath0 parent 1:1 classid 1:10 htb rate 120kbit ceil 120kbit tc class add dev ath0 parent 1:1 classid 1:15 htb rate 48kbit ceil 48kbit tc qdisc add dev ath0 parent 1:5 handle 5:0 sfq perturb 10 tc qdisc add dev ath0 parent 1:10 handle 10:0 sfq perturb 10 tc qdisc add dev ath0 parent 1:15 handle 15:0 sfq perturb 10 tc filter add dev ath0 protocol ip parent 1:0 prio 1 u32 match ip dport 22 0x flowid 1:5 tc filter add dev ath0 protocol ip parent 1:0 prio 1 u32 match ip sport 22 0x flowid 1:5 tc filter add dev ath0 protocol ip parent 1:0 prio 1 u32 match ip dport 80 0x flowid 1:10 ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Re: [LARTC] pppoe gateway under linux
You can use rp-pppoe's pppoe-server combined with the kernel pppoe module. You need to compile rp-pppoe and pppd with pppoe kernel support (not the pppoe binary).

Re: [LARTC] htb: HowTo identify squid cache hits

--- CUT ---
If squid HIT then TOS is 0, if miss then 1.
Here is the place where you can download this:
http://sed.pl/~mrk/qos/squid_hit_miss_mark.patch
Throw in to queue of LAN only traffic coming from Squid.
Upload traffic from Squid always queue in users classes.
