Dotaz: Pripojeni k Wi-fi siti pod Kubuntu

[Geralt]

Ahoj,

marne se pokousim zprovoznit pod Kubuntu wi-fi pripojeni, a to presto ze jsem procetl nekolik prispevku z teto diskuze na toto tema i par clanku.

iwlist eth1 scan:

Poradte mi nekdo prosim, co je spatne, nebo co je jeste potreba udelat.

co je to za wifi kartu a co pouzivas za ovladac, jak si se pripojil k ty siti? Nastavil jsi WEP?

[Geralt]

karta je Wireless IEEE 802.11a/b/g (alespon to tady na nalepce pisou)

ovladac, ten nevim, kde zjistim

a k tomu routeru jsem se pripojit pres windows a nastavil tam WEP, ale na linuxu se mi k internetu pripojit nedari ...

[Smajchl]

No ja myslim, ze wep uz tam byl nastaven (Encryption key:on ve vypisu iwlist scan). Nazvem jsem myslel typ (a firmu), tohle je wifi standart.

Zadej do konzole lsmod a vypíše to seznam modulů, které jsou načteny - mezi nimi bude i ovladač tý wifiny a dej sem ten výpis, ale já si spíš myslim, že jsi nenastavil WEP klíč na linuxovym počítači (šifrování), nastavit by měl jít příkazem iwconfig wlan0 key 0123-4567-89 ty čísla jsou ten klíč v hexa (může to být i bez pomlček), detaily jsou v man iwconfig

Pokud ti to nepůjde, tak bych zkusil na routru vypnout WEP i WPA a zkusit se připojit jen na nezabezpečenou wifi a pak postupně zapnout WEP a WPA.

ten key jsem skutecne nenastavoval, ale bohuzel ani z man iwconfig jsem nepochopil, co to presne ten klic je; to, co mi vygeneroval wpa_passphrase je velmi dlouhe ...

[Smajchl]

Ta karta je v pohode, WEP je sifrovani, s wpa ti nepomuzu, to jsem nikdy nepouzival. To si najdi na internetu co to je WEP. Kdyz ho ale na AP vypnes nebude sice sifrovanej prenos, ale melo by ti jit se pripojit bez jeho nastavovani, za zkousku to stoji, pozor ale na to, ze je pak nezabezpecena ta sit.

[Geralt]

WEP na AP podle me nastavene neni, jen WPA-PSK a TKIP Encryption. Tedka bych to nerad rusil, radsi bych kdyby bylo mozne pripojeni nejak zprovoznit i s touto ochranou. Kdyztak sem zkopiruju vypis wpa_supplicant, pokud to pomuze, protoze se mi zda ze vypisuje same chybove hlasky, kterym bohuzel vubec nerozumim ...

[vencour]

Sám mam wpa v pohodě, musel jsem ho rozchodit jen přes zdejší rady, poradnu a tak ... změnili mi kluci profil . Takže ... musíte mít wpa_supplicant, upravíte konfigurák, projdete "man wpa_supplicant" a ... uvidíte. Já to dělam přes řádku, tedy spouštim skript, kde je na 1. řádce "wpa_supplicant -dd -c /etc/wpa_supplicant/wpa_supplicant.conf -i ath0 -D wext &" a pak ještě "dhcpcd ath0", v konfiguráku mam:

$ more /etc/wpa_supplicant/wpa_supplicant.conf
# This is a network block that connects to any unsecured access point.
# We give it a low priority so any defined blocks are preferred.

ap_scan=1

network={
       ssid="ESSID_apecka"
       key_mgmt=WPA-PSK IEEE8021X NONE

       scan_ssid=1
       pairwise=CCMP TKIP
       group=CCMP TKIP WEP104 WEP40

       psk="Fraze_nebo_heslo_jak_kdo_chce"
       eap=TTLS PEAP TLS

#       identity="user@example.com"
#       password="foobar"

}



#network={
#       key_mgmt=NONE
#       priority=-9999999
#}

K tomu, mam dojem, že musí být v kernelu přidělaná podpora pro kryptování, znam kluky, kterým tohle nestačí a právě "cryptographic API" snad by tam mělo pomoct? Když tak pomůže nějakej "debug" ... viděl jsem logy, kde to právě něco o tomhle psalo.

[Geralt]

Ja mam nyni v /etc/wpa_supplicant.conf:

network={
        ssid="Rychnovsky"
        key_mgmt=WPA-PSK
        scan_ssid=1

}

a kdyz jej spustim wpa_supplicant -ieth1 -c/etc/wpa_supplicant.conf -d, tak mi to vypise:

, ale internet bohuzel nenaskoci ...

Ok, především by mělo být výstupem správné funkčnosti wpa_supplicantu to, že vidíte linkovou vrstvu, tedy u "ip addr", že nemáte "no link detect" nebo "no-carrier". Že jsem tak smělej, co máte v tom kernelu za kryptování, algoritmy zapnuté? Budu to samé radit mému okolí ... tuto cestu zkontrolovat, jinak zatím nevím ... ať jsem konkrétní, já tam mam ... (nejsem si jistý, co je přesně potřeba)

P.S. fakt tam máte hostap? Nikdy jsem ho nemusel použít, slyšel jsem na něj spíš slova o problémech.
