Falha ao adicionar nova conexão: (2) Uma configuração 'sem fio' com um SSID válido é necessária se nenhum caminho de AP for fornecido

Question

Atualmente estou tentando compartilhar uma rede sem fio do arch-linux. Há um botão nas configurações de rede que deve permitir que eu faça isso:

Apertei o botão "Ligar", pois é exatamente isso que estou procurando!

Mas no terminal com o seguinte comando:

$ sudo journalctl -xef

Há alguns documentos aqui e ali que ainda estou lendo, mas não encontrei nada relacionado a esse erro além da mensagem de erro exata em algum código-fonte aqui:

https://github.com/lcp/NetworkManager/blob/master/src/nm-device-wifi.c#L1211

Um amigo testou no Fedora e funcionou imediatamente, ele encontrou uma ESSIDconfiguração que corresponde ao seu wifi criado aqui:

/etc/sysconfig/network-scripts/ifcfg-Hotspot

Mas não tenho esse caminho no Arch Linux.

háesta página wiki Software_access_point no archque pode conter algumas informações sobre como criar um hotspot. Seguirei isso mais tarde, mas se alguém tiver alguma informação sobre o erro, seria ótimo :)

Minha placa de rede deve ser compatível:

$ iw list

    Supported interface modes:
             * IBSS
             * managed
             * AP

             * P2P-client
             * P2P-GO

Realmente parece que suporta AP.

primeira tentativa

Eu tentei usar ponto de acesso

Criei um virtualenv python2.7 e instalei hotspotd==0.1.4, depois instaleihostapde dnsmasq.

$ sudo pacman -S hostapd
$ mkvirtualenv -p $(which python27) hotspot
$ workon hotspot
$ pip install hotspotd==0.1.4
$ sudo hotspotd -h

A small daemon to create a wifi hotspot on linux

positional arguments:
  {start,stop,configure}

optional arguments:
  -h, --help            show this help message and exit
  -v, --verbose


$ sudo hotspotd configure

Não sei por que isso wlan0está sendo usado, então tentei editar /home/gableroux/.virtualenvs/hotspot/lib/python2.7/site-packages/hotspotd/run.confe substituí wlan0pelo meu detectado wlp61s0:

Ainda não há ponto de acesso. procurei esse erro

nl80211: Não foi possível configurar o modo do driver

EUencontrei esta pergunta relacionada

Eu tentei o comando recomendado:

$ sudo iwconfig wlp61s0 mode master

Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlp61s0 ; Invalid argument.

Bem, parece que pode ser minha placa de rede, afinal.

Isso é definitivamente muito mais fácil no MacOS:/

Editar: Não consigo mais reproduzir esse problema desde que mudei para o Fedora e as coisas estão funcionando normalmente agora. Obrigado pela ajuda :)

Answer 1

Provavelmente o problema está no seu nome de host. Dê algum nome com um ponto final. por exemplo: "localhost.mine" ou simplesmente "localhost"

Você pode definir o nome do host via GNOME Control Center -> Detalhes -> Visão geral -> Definir nome do dispositivo.

Depois de definir um bom nome de host, crie o hotspot novamente.

Answer 2

eu useicreate_ap.

pacman -S create_ap
sudo create_ap -m bridge wifi_interface ethernet_interface test_arch vinod123

Nota: Você não poderá navegar na Internet no host. Talvez devêssemos usar NATem vez de bridge. Ainda não tentei confirmar nada em relação ao NAT.

Answer 3

Resolvi esse bug nm-connection-editorcriando manualmente uma conexão de ponto de acesso Wi-Fi. Depois disso, o botão "Usar como ponto de acesso" funciona conforme o esperado.
