Não há proxy para acessar a Internet.

    

Answer 1

Na sua linha de comando, veja se você pode fazer o seguinte:

$ echo "GET / HTTP/1.1
> 
> " | nc repo.mongodb.org 80

note preste atenção nas aspas, existem dois retornos na string pipped para o netcat (pode ser chamado nc no seu sistema). Você deve obter uma resposta como abaixo. Se o netcat não estiver instalado, você também poderá usar o telnet se ele estiver instalado.

Se você não obtiver isso, sua conexão HTTP será interceptada por um proxy de algum tipo, possivelmente um proxy TCP ou proxy transparente - e você precisaria conversar com seu provedor de rede para obter mais informações.
