Dotaz: Hostapd nejede: Jak přejmenovat wifi0/eth2 na wlan0?

[Hrabosh]

Zdravím.

Snažím se rozjet hostapd, aby moej karta s chipsetem Prism 2.5 mohla fungovat jako APčko s WPA2. Při pokusu o start mi to píše:

DebServer:~# hostapd /etc/hostapd/hostapd-commented.conf
Configuration file: /etc/hostapd/hostapd-commented.conf
ioctl[PRISM2_IOCTL_HOSTAPD]: Invalid argument
Failed to set encryption.

VLAN: vlan_set_name_type: SET_VLAN_NAME_TYPE_CMD name_type=2 failed: Package not installed

Wifi je sice vidět, ale hlásí se jako zapezbepčená WEP a nejde se připojit. Zkoušel jsem updatnout firmware (což se podařilo) a v rámci toho jsem si všiml, že updatovací tool očekával informace o kartě v adresáři /proc/net/hostapd/wlan0.

KArta se ale v systému hlásí jednak jako eth2 a potom taky wifi0.

Jde nějak nastavit/změnit, jak se bude karta v systému hlásit? Napadlo mě, jestli ten hostapd taky neočekává info na /proc/net/hostap/$nazev_karty a protože /proc/net/hostap/eth2 ani /proc/net/hostap/wifi0 neexistuje, tak to háže chyby ....

UPDATE: Po upgradu firmwaru se WiFi už hlásí jako WPA-PSK, ale při pokusu o připojení:

Do nedávna jsem provozoval hostapd s hostap_pci zařízením a držel jsem se hostapd verze 0.6.9. Novější měli problém s inicializací, ale nechtělo se mi řešit, čím to je.

[Hrabosh]

Tak nakonec se mi podařilo editováním souborů v /etc/udev/tu kartu přejmenovat na wlan0. Nicméně to nepomohlo ani zbla. Zkoušel jsem tedy downgrade na 0.6.9. Po startu to vypad slibně:

DebServer:~# /usr/local/bin/hostapd /etc/hostapd/hostapd-commented.conf 
Configuration file: /etc/hostapd/hostapd-commented.conf
Using interface wlan0 with hwaddr 00:60:b3:6e:15:50 and ssid 'HneT'

v dmesgu je:

wifi0: enabling hostapd mode
wifi0: registered netdevice wlan0ap

Ale když se chce někdo připojit:

wlan0: STA 74:f0:6d:72:2f:b7 IEEE 802.11: authenticated
wlan0: STA 74:f0:6d:72:2f:b7 IEEE 802.11: associated (aid 1)

wlan0: STA 74:f0:6d:72:2f:b7 IEEE 802.11: deauthenticated due to local deauth request

v dmesgu:

wifi0: unknown crypto alg 'NONE'
wifi0: unknown crypto alg 'NONE'
wifi0: unknown crypto alg 'NONE'
lib80211_crypt: registered algorithm 'CCMP'

Tohle se opakuje několikrát.

Tohle je můj starý hostapd.conf, který jsem používal s hostap_pci:

Kanál a výkon jsem nastavoval v init scriptu před spuštěním hostapd.

A tohle jsem našel v syslogu:

[Tady je už klient asociovaný a pak už následuje DHCP]

A pak tam mám spoustu šifrovacích a hašovacích funkcí, ale většinu kvůli IPsecu, takže netuším, co z nich je potřeba pro hostapd.

Diky!

Uz se mi dari pripojit, ale kdyz se klient odpoji, na serveru se obevi:

wlan0: STA 00:04:23:84:b5:39 IEEE 802.11: disassociated
ioctl[PRISM2_IOCTL_HOSTAPD]: Invalid argument
Failed to set encryption.
wlan0: STA 00:04:23:84:b5:39 IEEE 802.11: deauthenticated due to inactivity

ioctl[PRISM2_IOCTL_HOSTAPD]: No such file or directory
ioctl[PRISM2_IOCTL_HOSTAPD]: No such file or directory
Could not remove station from kernel driver.

Pri snaze o opetovne pripojeni:

wlan0: STA 00:04:23:84:b5:39 IEEE 802.11: authenticated
wlan0: STA 00:04:23:84:b5:39 IEEE 802.11: associated (aid 1)

wlan0: STA 00:04:23:84:b5:39 IEEE 802.11: deauthenticated due to local deauth request

A musim to cele shodit/nahodit znova. Jinak i to pripojovani obsahuje nejake chyby, ale jede to:

DebServer:~# hostapd /etc/hostapd/hostapd-abcl.conf
