[LARTC] htb statistics
Hi, how long is the period over that the htb rate of a class will be estimated? on a site i read 10 sec but the update rate is 10 sec. i think the average rate determination is nearly 120 seconds? What is the exact meaning of requeues? If one packet must be 5 times requeued this statistics value is 5? When will be a packet requeued because in my case this value is always 0... Is overlimits a summary of dropped, requeued and delayed packets, because all dropped or requeued packets were previously marked as overlimit? I have a htb root qdisc,three htb classes, and two leaf-sfq-qdiscs. The root class will shaping the traffic to 512kbit. So i meant that the overlimits value of this class will be increased if someone would send the data faster. but the overlimits will be counted only in the root htb qdisc. is there a reason for this behauvior?

[LARTC] download/upload restriction.
Hi all I have following script in my server. Now I want to restrict ip 192.168.3.2 to 128kbps (downlink). But in this case client can download upto 500kbps and upload cannot exceed more than 20kbps. Now what should I do to restrict client 192.168.3.2 within 128kbps downlink and 64kbps uplink. tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1:0 htb tc class add dev eth0 parent 1:0 classid 1:1 htb rate 300kbit tc class add dev eth0 parent 1:0 classid 1:11 htb rate 128kbit ceil 300kbit tc class add dev eth0 parent 1:0 classid 1:12 htb rate 128kbit ceil 300kbit tc class add dev eth0 parent 1:0 classid 1:13 htb rate 50kbit ceil 300kbit tc qdisc add dev eth0 parent 1:11 handle 210: pfifo limit 10 tc qdisc add dev eth0 parent 1:12 handle 220: pfifo limit 10 tc qdisc add dev eth0 parent 1:13 handle 230: pfifo limit 10 tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip dst 192.168.3.1 match ip sport 20 0xfff flowid 1:11 tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip dst 192.168.3.1 match ip sport 21 0xfff flowid 1:11 tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip dst 192.168.3.2 flowid 1:12 tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip dst 192.168.3.3 flowid 1:13 Regards, Umesh ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
PHP script to get MySQL data and make TC speed limit Re: [LARTC] (no subject)
Dear Anirudh,
You will probably get better help if you write your setup, what you have
tried, how it does not work, and write a subject.
Here is a PHP script which looks IP numbers and limits up in a database
and generates a simple TC HTB limit rule per host.
You may be able to modify it to be useful for you.
Notes:
- This script is run from the console, not a web server. You will need
command line PHP installed. Or you can rewrite it in a language of your
choice.
- We only have two limit options: limit everything to 255 Kbit/s, or
limit only packets that have been marked as "6" by some firewall rules
to 255 Kbit/s. You will want to rewrite this bit to get the speed value
from the database, but you can simplify the "marked as 6" bit away.
- Warning: we only limit download speed. You will probably want to limit
upload speed as well! You will probably want to do this by matching on
IP number on the way OUT of you INTERNET interface.
#!/usr/bin/php
$sql_query = "SELECT mac, last_seen_ip, `limit` FROM mac_info WHERE
`limit` > 0 AND expiry_date > NOW()";
$result = mysql_query($sql_query)
or die(mysql_error());
$i = 1;
while ($current_row = mysql_fetch_assoc($result)) {
$ip = $current_row['last_seen_ip'];
$limit = $current_row['limit'];
$mac = $current_row['mac'];
if (check_internal_ip($ip)) {
$out .= sprintf($cmd1,$i,$mac,$i);
if ($limit == 1)
$out .= sprintf($cmd2dkstream,$ip,$i);
elseif ($limit == 2)
$out .= sprintf($cmd2all,$ip,$i);
$i++;
}
unset($ip); unset($limit); unset($mac);
}
if($debug)
print $out;
else
logfile($out);
`$out`; // run everything in 'out'
?>
---
The output looks like this:
# delete all existing queue disciplines
tc qdisc del dev eth2 root
# attach queue discipline HTB to interface eth2 and give it handle 1:0
tc qdisc add dev eth2 root handle 1:0 htb
# host 1 mac x
tc class add dev eth2 parent 1:0 classid 1:1 htb rate 255kbit burst 255kbit
tc filter add dev eth2 protocol ip parent 1:0 prio 1 u32 \
match ip dst 172.16.xxx.xxx \
flowid 1:1
# host 2 mac
tc class add dev eth2 parent 1:0 classid 1:2 htb rate 255kbit burst 255kbit
tc filter add dev eth2 protocol ip parent 1:0 prio 1 u32 \
match mark 0x0006 0x \
match ip dst 172.16.xxx.xxx \
flowid 1:2

[LARTC] Problem with Julian Anastasov's routing patches
Hello, I wanted to try some multipath setup with Julian's patches, and when rebooting on the newly patched kernel, without any multipath routes (only one interface up and one default gateway), my SSH connections to the server freeze after a few seconds. I tried with and without bridges (I sometimes have a bridge between a tap device and my eth0) with the same results. When I close and try to reconnect, sometimes it works, sometimes it doesn't, but when it does the client (on my laptop) always stops receiving data from the server after a random time, between 1 and 60 seconds approximately. Also HTTP connections to the server's apache daemon seem to suffer from this problem, and I usually have to "reload" the page from my browser several times in order to have a complete page (it usually stops in the middle of the page loading). Tracing with tcpdump on the laptop, the connections seem still up (the server sends ACK packets, and when closing the console on the laptop, I can see the FIN stuff closing TCP connection successfully), but the ssh console is frozen on the laptop (no real replies from server apart from ACK). I tested several times with and without the patches, and it strongly appears to be related to Julian's patches. - Is it a known issue for these kernels (2.6.21)? - Is there a way to repair that in order to be able to use these patches? I'm using a vanilla kernel 2.6.21.7 with the following patches: - IMQ - Layer 7 - Julian's route patches (version for kernel 2.6.21) relevant parts of .config: CONFIG_IP_ROUTE_MULTIPATH=y # CONFIG_IP_ROUTE_MULTIPATH_CACHED is not set ... # CONFIG_BRIDGE_NETFILTER is not set # CONFIG_BRIDGE_NF_EBTABLES is not set CONFIG_BRIDGE=m Thanks for any help, François. ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
