Java v prohlížeči nefunguje

[Ota Trkola]

Všiml jsem si že mi na Squeeze nejede java v prohlížeči. Nevěděli byste někdo proč?

Vyvojari to zduvodnuji tim, ze vsechny "moderni" OS preferuji IPv6 a tak to nastavili jako default a konfigurace Javy to ma nastavene taky jako default a ve vysledku to zpusobi, ze se proste nemuze Java pripojit k siti a nemuze tak stahnout prislusny modul a proto to spadne. Proste genialni. Pokusim se pohledat, jak jsem to vyresil.

Koukni se do /etc/sysctl.d/bindv6only.conf

Ja tam mam net.ipv6.bindv6only = 0

Co tam mas ty?

Ahoj, děkuji moc za radu. Pomohlo to! Já tam měl:

net.ipv6.bindv6only = 1

Změnil jsem to na = 0  a šlape to!
