[MASOCH-L] Forçar autenticação PAP

[Hamilton Vera]

Caros, boa tarde.

Estou utilizando o modem Huawei EM 770W para utilizar os serviços de "VPN"
da vivo "zapvpn.vivo.com.br" . Pelo que percebi esse serviço utiliza a
autenticação PAP.

Infelizmente o modem EM 770W por algum motivo desconhecido só tenta
negociar MS-CHAP. Já tentei várias opções no PPPD do linux para forçar
negociação PAP:


ttyUSB0
921600
lock
crtscts
modem
passive
novj
defaultroute
noipdefault
noauth
#hide-password
persist
holdoff 10
maxfail 0
debug
kdebug 4
-chap
refuse-chap
refuse-mschap
refuse-mschap-v2

porém o modem persiste no chap:

Connect: ppp0 <--> /dev/ttyUSB0

Alguém já passou por esse problema?



Obrigado.
