OT: squid a nefunkcnost internetbankingu

[Jozef Drahovsky]

Riesil som ten isty problem,
po dlhych perepatich a nevysvetlitelnych chybach som sa dozvedel,
ze bankovy software na servere v banke ma nastavene prisne timeouty.
Ak klient komunikoval na linke sam, tak vsetko bolo ok, ak 
linka/proxyserver
bol zatazeny v case rovnomerne (napr. vela ftp prenosov) tak vsetko
bolo vsetko tiez ok, ale ak zataz bola dynamicka a vyrazne sa menila 
doba odozvy,
tak to bankova strana zhodila.

V prvej faze sa zaviedlo pridelovenie pasma cez dummynet a poprosila banka
o spolupracu. V druhej faze sa navysila rychlost linky a bezi to bez 
problemov doteraz.

S pozdravom

Jozef Drahovsky
