[LARTC] Racoon/ipsec/setkey questions/bugs

I have two x86 laptops one with ipsec-utils 0.7 and one with 0.7.1. It seems that the filtering rules in setkey don't work as the man page describes. Below I have listed some combinations of what has worked and what has failed as a bi-directional pair. A to b and then b to a. For example. F

RE: [LARTC] how hierarchical is HTB?

Few quick comments: HTB parent rate should never be less than the sum of its children. This is referring to the rate parameter not the ceil. Class 1:20 needs to equal 1:200+1:201. You will get strange results if you try and test with any configuration where the the sum of all childeren rates

RE: [LARTC] PRIO and TBF is much better than HTB??

Just to comment. Yes you will get better latency with prio and tbf. However there creation purposes were for different end goals. HTB has the ability to create a class structure that can break your link bandwidth up into different classes. The prio setting in HTB is to determine which class

RE: [LARTC] Data rate with HTB

You probably want to change your default class to 12. This will send your all traffic not matched by the filter to your BE class. Right now your sending it to 1:1 by default. Also your filters don't look correct. I would just filter based on the tos bit. Example EF Tc filter add dev $DEV par

RE: [LARTC] Modifying traffic shaping rates according to the amount ofactive users

Based on your requirements I would use HTB. Ceil (the maximum borrowed rate) HTTP traffic to 80% of your bandwidth in one class. In the other class ceil rate to 20%. If HTTP needs more bandwidth or SMTP they can borrow between each other. Example: 40% SMTP 60% HTTP - H

RE: [LARTC] prio not seeming to work

Two questions 1.) When you type tc class ls dev ethx - Do you see that both ftp streams are flowing into their proper class; 1:1, 1:3? 2.) Are you sending enough traffic to reach the point of congestion on you link? - If your not then it will service all the traffic at the same

How the guide say I expect to see on router (with command tc -s qdisc ls dev eth0) that unclassified traffic, like ssh, get rounded to 20: but it doesn't happen. - Traffic just doesn't get rounded to a class. If you want traffic going to a class you need to specify a filter. Did you by chance
