Zdravim,
kvuli projektu pro jeden vyzkumny ustav jsem se ted snazil rozchodit AP mod na bezdratove karte na pandaboardu. Bezi na nem Debian jessie. Postuoval jsem podle instrukci, ktere jsem nasel
tady a uspesne. Nyni se muzu pripojit na Pandaboard pomoci Wifi z libovolneho pocitace bez nutnosti pouzivat router.
Problem je, ze prestalo fungovat pripojeni na internet, ktere fungovalo prez dratovou sit. Pandaboard stale dostane pridelenou IP adresu kdyz pripojim LAN kabel a muzu se na nej pripojit pomoci ssh, ping na nejakou webovou stranku uz ale neprojde. Predpokladam, ze se to deje kvuli zmenam ktere jsem provadel pri nastavovani toho AP modu. Take bych rad, aby zarizeni, pripojena prez Wifi k tomu pandaboardu mohla sdilet pripojeni k internetu.
Konfigurace by mela byt nastavena tak, ze dratova sit na zarizeni
eth0 dostava adresy prez DHCP a bezdratova sitova karta
wlan0 je v AP modu a s pomoci
dnsmasq prideluje adresy v rozsahu 192.168.4.10 ... 50. Abych se priznal ne zcela chapu nastaveni v /etc/network/interfaces. Puvodne stacilo strcit LAN kabel do sitovky na Pandaboardu a baliky jsem tahal normalne prez apt-get bez dalsiho nutneho nastavovani.
Moc bych poprosil, kdyby se nekdo zkuseny mohl podivat na ty konfiguraky a rict mi,kde je co spatne.
