hello there first of all - yes, I''ve read LARTC Howto; - yes, I''ve google''d a bit secondly - if i miss smth. please give me a pointer to some source of info, instead of shouting at me clue: from LARTC Howto [...] The frame is actually the unit on which traffic control is performed. [...] so when i''m shaping with htb ( and fe. sfq ), the kernel is ''slowing'' rate of frames in Layer 2, so setting htb rate to 2mbit means ''set the speed of frames ( not packets ) to 2mbit''; on the other hand, filters are using at least Layer 3 infos ( adresses, port numbers, etc.; or MARKs which have been set via iptables, but based on at least L3 info ); 1st question - are these top statements right? 2nd question - how is this connected in kernel ( shaping frames, but using higher layers infos) 3rd question - probably ntg, but perhaps someone knows smth: iptables -L -vnx shows amount of bytes including ethernet header and trailer, or only size of IP packets ( incl. payload, of course )? thanks in advance przemek.krol -- ------- chaos, panic and disorder ... looks like my work is done here ------- _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
