včera 13:11 | Nová verze

Po téměř dvou letech byla vydána nová verze 4.0 linuxové distribuce Audiophile Linux (též AP-Linux-V4). Tato distribuce vychází z Arch Linuxu, používá systemd, správce oken Fluxbox a vlastní real-time jádro pro nižší latence. Z novinek můžeme jmenovat podporu nových procesorů Intel Skylake a Kaby Lake nebo možnost instalace vedle jiných OS na stejný disk. Pokud se zajímáte o přehrávání hudby v Linuxu, doporučuji návštěvu webu této

Byla vydána nová stabilní verze 1.9 (1.9.818.44) webového prohlížeče Vivaldi (Wikipedie). Z novinek vývojáři zdůrazňují podporu nového vyhledávače Ecosia. Ten z příjmů z reklam podporuje výsadbu stromů po celém světě (YouTube). Nově lze přeskupovat ikonky rozšíření nebo řadit poznámky. Nejnovější Vivaldi je postaveno na Chromiu 58.0.3029.82.

    Zdravim mam problem s
    02:0a.0 Ethernet controller: Atheros Communications Inc. Atheros AR5001X+ Wireless Network Adapter (rev 01)
    
    , kdyz vytvorim ap bez klice , vse funguje jak ma , ale jakmile mu vnutim klic . Tak zadny klient se nepripoji . Pouzivam ovladac ath_pci , s adhocd a ath5k kartu v modu ap vubec nenastavim . Ve starsim jadre vse fungovalo.

    mám
    00:0e.0 Ethernet controller: Atheros Communications Inc. AR2413 802.11bg NIC (rev 01).
    Tuto wifi kartu provozuju v AP módu následujícím způsobem:
    wlanconfig ath0 destroy
    wlanconfig ath0 create wlandev wifi0 wlanmode ap
    iwconfig ath0 channel 9
    ifconfig ath0 0.0.0.0

    režim AP a včetně šifrování zajišťuje hostapd. Konfigurák pro hostapd jsem našel na internetu.
