Re: Priorytety na uslugi

13 Maj 2005

      Hejka,

co prawda chcialem to nieco pozmieniac przed upublicznieniem,
tak zeby nie przypominalo jednej wielkiej prowizorki, ale chyba
nigdy tego nie zrobie... w zalaczniku jest skrypt wykozystywany
przeze mnie do generowania wszystkiego z lms'a co mi potrzebne
(poza mackami chyba)

uwaga 1: skrypt olewa up/download z  lms'a, robi to po swojemu
uwaga 2: tworzy 3 kolejki dla roznych uslug z calkowicie osobnymi
              limitami
uwaga 3: umozliwia natowanie publicznych ip (DNAT/SNAT)
uwaga 4: jest brzydki straszliwie bo przerabialem to co bylo pod reka
              tak by tylko dzialalo
uwaga 5: kernel ktorego uzywam paczowany jest zbiorczym patchem
              z www.inet.one.pl

w razie czego moge cos wyklarowac :)
btw. konstruktywne uwagi mile widziane.
