Mi sono appena trasferito in un nuovo appartamento e con la connessione a Internet tramite un router e sto scoprendo che non riesco a collegarmi a parecchi siti che utilizzano SSL.
Ad esempio, cercando di connettersi a PayPal:
curl -v https://paypal.com
* About to connect() to paypal.com port 443 (#0)
* Trying 66.211.169.3... connected
* successfully set certificate verify locations:
* CAfile: none
CApath: /etc/ssl/certs
* SSLv3, TLS handshake, Client hello (1):
* Unknown SSL protocol error in connection to paypal.com:443
* Closing connection #0
curl: (35) Unknown SSL protocol error in connection to paypal.com:443
curl -v -ssl https://paypal.com
dà lo stesso risultato.
Per alcuni siti funziona:
curl -v https://www.google.com
* About to connect() to www.google.com port 443 (#0)
* Trying 74.125.235.112... connected
* successfully set certificate verify locations:

Questo è un ISP giapponese e anche se mi sto collegando con un cavo al modem / router, devo aggiungere un nome utente e una password, ma con la connessione "Wired" di Ubuntu non sono riuscito ad aggiungerli. La mia coinquilina mi ha detto di creare una connessione OCN ma non sono sicuro che sia un nome di un tipo di rete o solo la compagnia giapponese ... ma dopo aver visto il suo computer abbiamo scoperto che era una connessione PPPoE. Dopo aver cercato su Google ho imparato che per creare una connessione PPPoE avrei dovuto creare una connessione DSL e che avrei potuto aggiungere una password e un nome utente. Ho anche cambiato la connessione "Wired" per non connettermi automaticamente.
Ottengo lo stesso problema se collego direttamente al modem.
Ho provato a cambiare DSL MTU in 500, 1500, 1492 e 1482 ma non ha fatto differenza.
Inoltre, per qualche motivo Ubuntu non rileva sempre la connessione, a volte devo riavviare per collegarla.
Error 7 (net::ERR_TIMED_OUT): The operation timed out
. FireFox continua a provare a caricare ma non lo fa mai (la pagina non cambia). Console e Network non mi danno nulla ...
curl
o non si aprono anche con altri browser?
