| no fleg, co sa uz da rozpravat o tom, ze si pridas do jadra modul za pomoci ktoreho si omarkujes p2p pakety a potom ich bud dropujes, alebo hodis na nejaku trapnu linku. |

| Hladaj layer7-filtering na sf.net pre linux-i, lepsie povedane L7-filtering. Toto ti umozni filtrovat a radit do tried p2p spojenia. Ale myslim si ze by s p2p nemal byt problem, pokial pouzivas per IP shaping. Nech si kazdy svoju linku zaplni ako chce. Ak pouzivas len priorizaciu, tak ano, toto zverstvo je problem. |

| kazdy pouziva prioritu ako pravidlo imho lebo dat userovi urcite pasmo ktore s nikym nezdiela je garantovana linka ktora stoji trosku ine peniaze ako zdielana |

to fleg: to ano, ale v takomto pripade to riesim tak, ich dam do jednej skupiny so stropom rychlosti a na triedu zakvacim esfq scheduler. V tomto pripade sa volna kapacita v danej triede deli medzi tolko ip z triedy kolko ip akurat komunikuje a to rovnomerne. A priopizaciu pouzivam, len ked ma o to poziadaju ti, ktory sa
pripajaju viacerymi pocitacmi na jednu zmluvu, t.j. ak domacnost s 3 kompmi ide cez 1 zmluvu tak "aby aj mamka mohla zaplatit seky cez i-banking, ked ma syn akurat spustenych 10 download managerov". |

| hm to je tiez riesenie...ale nezda sa mi velmi vyhovujuce. co v pripade ze jedna trieda je uz obsadena na prasknutia a ta druha je poloprazdna a ma zbytkovu kapacitu? |

| Volby bounded a isolated su len pre cbq, co napovazujem za najlepsie riesenie pre konecnych klientov, pretoze v cbq je polozka rate "speed knob" , vhodnejsie je pouzit htb s polozkami rate a ceil. Ale proti gustu.. To fleg: pre tych, ktory platia za zdielanu linku, mam nastavenu polozku rate aj ceil a je pre nich volny cely zvysok linky, ale pre kazdeho len do vysky ceil |

| ja pouzivam cbq pretoze mi zatedy postacuje ale casom budem asi musiet prejst na htb preto ma zaujima a tak ako to mas ty si to nejako predstavujem aj ja...cize triedy s ceil a rate (kde rate bude suctom ratov kleintov v triede) akurat som si nebol isty ako je to s poziciavanim ceilov;o) |

namiesto pojmov a dojmov doporucujem radsej hodit funkcny skript, kde si to kazdy moze vyskusat in real life.
teoretizovat o jednotlivych optionoch podla mna nema pre userov velky vyznam, nakolko manual k QoS cita malokto a este menej ludi ho chape.
Ad2, jedna vec je teoria a druha prax
ps: poprosim prispievajucich, ktori maju k tejto teme co povedat, nech skusia pripojit aj popar prikazov s pripadnym konfigurakom. |

#dalsie IP sa pridavaju analogicky
#koniec skriptu
script treba po napisani spustit (musi byt executable), prve spustenie po boote bude nadavat, kedze sa pokusa deletovat v danom case neexistujuce triedy, to tam ale je z dovodu vycistenia pred samotnym nahodenim obsahu, takze aj po zmene staci script len spustit a on sa uz o vsetko postara...
nezabudnite si vymysliet neake rozumne ID na triedy 
urcite sa tam vyskytuju neake chyby, v kazdom pripade mi to ale v takomto tvare realne funguje.... IPcky som tam ponechal realne, kedze na zaklade IP generujem aj ID tried (kto chce, nech sa inspiruje). Niektore hodnoty boli ziskavane experimentalne  |

Zdravim chcem sa spytat ci mi niekto moze ukazat ako bude vypadat dany script.HTB
konekt do netu 256kbit eth0
klienti v skupine zo zdielanou linkou 128 kbit down 64kbit upload
ipadresy 192.168.5.100-103
klienti s garantovanou linkou 64 kbit down 32 kbit upload
ip 192.168.5.104-105
a nastavit maximalnu priortu na port 80 aby aj pri zatazeny isli web stranky co najrichlejsie na to si stazuje vecsina ludi ze sa im dlho nacitava web.
a popis k jednotlivim nastaveniam tiez pomoze aspom do zaciatku pre
zacinajucich linuxakov. |
