wvdial: PPP守护进程已死亡: Pty程序错误(退出代码= 9)

Question

我试图将AnyDATA but 890-WH调制解调器配置为在Linux中工作，但没有成功。我是捷克运营商O2的客户，使用Ubuntu14.04。

我曾经尝试使用Network，移动宽带选项卡进行连接，但从那以后我就没有成功。

这是我的wvdial.conf：

[Dialer Defaults]
Init2 = ATQ0 V1 E1 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
Phone = *99#
Stupid Mode = 1
ISDN = 0
Username = a
Init1 = ATZ
Password = a
Modem = /dev/ttyUSB0
Dial Command = ATDT
Baud = 9600

[Dialer CDMA]
Auto DNS = 0
Init1 = ATQ
Init2 = ATZ
Stupid Mode = 1
Phone = #777
Idle Seconds = 0
Modem = /dev/ttyUSB0
Username = 601xxxxxx@cz.o2.com
Dial Command = ATDT
Password = xxxxxx
Baud = 1500000


[Dialer three]
Init2 = ATZ
Init3 = ATQ0 V1 &D2 &C1 S0=0 +IFC=2,2
Init5 = AT+CGDCONT=1,"IP","internet"
ISDN = 0
Modem = /dev/ttyUSB0
Modem Type = Analog Modem

这是/var/log/syslog文件的重要部分：

Jul 23 20:25:07 wigos-hp-lx pppd[5524]: pppd 2.4.5 started by root, uid 0

我还找到了一些指南如何在没有wvdial的情况下设置连接--但是这些指南依赖于由pon <connection-name>启动连接，但是当使用这个命令时，我没有得到输出，什么也没有发生。

调制解调器也支持码分多址网络，但使用wvdial时的错误是相同的。

Answer 1

通过一些尝试和错误，我在我的/etc/ppp/options中找到了以下部分：

# BSD licensed ppp-2.4.2 upstream with MPPE only, kernel module ppp_mppe.o
# {{{
refuse-pap
refuse-chap
refuse-mschap
# Require the peer to authenticate itself using MS-CHAPv2 [Microsoft
# Challenge Handshake Authentication Protocol, Version 2] authentication.
require-mschap-v2
# Require MPPE 128-bit encryption
# (note that MPPE requires the use of MSCHAP-V2 during authentication)
require-mppe-128
# }}}

注释掉所有这些refuse-*和require-*选项使身份验证(和连接)成功。
