Hi... I''m working with HTB, and have a question... what happen if I create a class of "8kbit" ?? I get a log : "HTB: quantum of class .... is small. Consider r2q change" but, my r2q=1 I can''t reduce that variable... how must I procced ? Thank you! mac _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lar...

Hi, I''m getting this warning/error in /var/log/messages: May 26 18:21:05 mail kernel: HTB: quantum of class 10010 is small. Consider r2q change. Its a big deal? What should I do? Many thanks Oliver -- Oliver Schulze L. <oliver@samera.com.py>

Dear all, I''m new to traffic shapping although i have gone through marking and HTB queueing but i felt trouble in tc filter . I wonder if any one give me the hints about quantum or r2q. i guess quantum is used when two class has same prio and rate and want to give first priority between them and control the borrowing traffic. It should be set more than MTU too. But my question is that how can we set quantum exactly , i mean is there any calculation need to set this qua...

Hello again, I need to change the R2Q for my script, as setting the quantum manually for each class is painful. Can you tell me exactly where to set R2Q = x? I get syntax errors all the time. Should it be specified for each class? I do not know where to place this setting... Thanks in advance, Vlad Mihai _______________________________________________ LARTC mailing l...

Hi, I have a Debian based NAT router. How can I manage upstream egress bandwidth based on the LAN ipadress in the network below? My goal is that host1 get a minumum of 10Mbit up/down and host2 gets a minimum of 90Mbit up/down, both max 100Mbit up/down? targethost 172.16.255.254 | | 172.16.0.1 natrouter

Hello all, I have a question about the quantum parameter of a HTB class: Is there a formula to calculate the quantum parameter of a class, having the rate and ceil as parameters?

Have people given thought to the private key encryption methods in light of potential quantum attacks? While the recent paper about breaking 50bit RSA doesn't pose a threat I've been thinking about future harvest now, decrypt later attacks against CC20 and AES. Are there post quantum ciphers that can effectively replace these available or in development? Is the threat still too far...
