Dotaz: wpa_supplicant - síť funguje jen pár sekund

[marekv]

Ahoj,

v /etc/wpa_supplicant.conf mám:

ctrl_interface_group=wheel
ap_scan=1
network={
    ssid="moje"
    proto=WPA
    key_mgmt=WPA-PSK
    psk="zzz"
    password="zzz"
}

Spustím internet:

> wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant.conf

Ale, jak je vidět z výstupu, pár sekund funguje, pár sekund zase ne a takhle pořád dokola. Co s tím?

Podobne veci sa stavaju ak je na pozadi pustena dalsia instancia programu wpa_supplicant (napr. Network Manager si pusta vlastnu instanciu, ktora sa podobne bije s rucne pustenym wpa_supplicantom), pripadne dhclient alebo dhcpcd. Takze postupne overit ps -A|grep wpa_supplicant (dhclient a dhcpcd) a zistit, ci nahodou nebezi viac instancii a vypnut sluzbu, ktora dany proces spustila.

Perfektní, děkuji! Běžely dva wpa_supplicanty, tak jsem jeden killnul a už to funguje.
