Me acabo de mudar a un nuevo apartamento y con conexión a Internet a través de un enrutador y descubro que no puedo conectarme a varios sitios que usan SSL.
Por ejemplo, intentando conectarse 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
da el mismo resultado.
Para algunos sitios funciona:
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:

Este es un ISP japonés y, aunque me conecto con un cable al módem / enrutador, necesito agregar un nombre de usuario y una contraseña, pero con la conexión "cableada" de Ubuntu no pude agregarlos. Mi compañera de casa me dijo que creara una conexión OCN, pero no estoy seguro de si ese es el nombre de un tipo de red o solo de la compañía japonesa ... pero después de mirar su computadora, encontramos que era una conexión PPPoE. Después de buscar en Google, aprendí que para crear una conexión PPPoE necesitaría crear una conexión DSL y que podría agregarle una contraseña y un nombre de usuario. También cambié la conexión "cableada" para que no se conecte automáticamente.
Me sale el mismo problema si me conecto directamente al módem.
Intenté cambiar la MTU DSL a 500, 1500, 1492 y 1482, pero no hizo la diferencia.
Además, por alguna razón, Ubuntu no siempre recoge la conexión, a veces tengo que reiniciar para que se conecte.
Error 7 (net::ERR_TIMED_OUT): The operation timed out
. FireFox sigue intentando cargar, pero nunca lo hace (la página no cambia). La consola y la red no me dan nada ...
curl
o tampoco se abren con otros navegadores?
