Diky, diky! Mam to pripojeny pres ethernet kabel. Sitovani moc nerozumim, ale to nastaveni, ktery davam Ubuntu je nasledujici:

IP adresa: 10.102.39.147 (semtam to testuju s .39.148, to je verejna)
Maska podsite: 255.255.255.248
Vychozi brana: 10.102.39.145
DNS: 10.102.0.252

Takze tam NAT asi neni. Problem je, ze se to chova dost nahodne. Casto ten ping projde bez problemu, ale nekdy se zasekne. Stejne jako cokoliv (nacitani stranky, stahovani updatu, ...) Kazdopadne zrovna ted jsem napingoval tohle na google.com:

Na tom routeru bezi Linux, muzu se na nej telnetnout, kdyby to bylo potreba. Nevypada to, ze by se pri techhle problemech neco novyho (tykajiciho se sitovky) objevovalo v dmesg. Jeste vypis lspci:

Ahoj,

pripojeni v Ubuntu ke Klfree mi jede mizerne (co to znamena viz nize). Vsechny jiny kombinace:

- Klfree ve Windows
- ne-Klfree ve Windows
- ne-Klfree v Ubuntu

jedou naprosto bez problemu. Cili Ubuntu si nerozumi s necim specifickym pro Klfree. Chova se to tak, ze pripojeni jakztakz jede a nekdy se "zasekne" a stranku uz nenacte. Kdyz se odpojim a zase pripojim, tak to zas trochu jede. Nasledujici vypis pingu je naprosto typicky:

Mam router Asus wl500g.

ze to je jen demo...

http://totalburnout.50webs.com/ (nejak se tam ale jeste nepricitaji body)

//www.meebo.com, protoze je to webova aplikace a funguje ve vsem (kde je Firefox ci neco podobne ohnivého).

no, take zalezi na rozliseni dpi te fotky.

DPI by do toho vstupovalo jen, kdyby jsme se bavili o fyzicke velikosti te fotky (treba v cm), jakmile se velikost uvede v pixelech, tak uz z hlediska pameti tomu skriptu na DPI nesejde. Ale ani velikost v px jednoznacne neurcuje, kolik pameti bude gd potrebovat na zmenseni.

Zkus velikost pameti pro PHP zvetsit na zacatku skriptu nasledovne:

<?php

ini_set('memory_limit','48M');

?>

Nemusi to byt ale nutne povolene na serveru.

32 MB by ale melo stacit i na pomerne velky fotky (1024x768), takze bych si taky rozmyslel, co tam uploadovat. Bohuzel gd knihovne nezalezi jen na rozmerech, ale i na vlastnostech konkretni fotky, takze se neda najit jeden konkretni rozmer, pod ktery by to fungovalo vzdy. A jako bonus se myslim neda tohle selhani resamplovaci funkce osetrit v PHP takze to vzdycky sejme fatal error.
