Я работаю на машине с Ubuntu 12.04 и могу использовать некоторую помощь для установления ppp-соединения с моим провайдером через модуль Telit HE910 mPCIe.

Конфигурация ppp:

# pppd launch configuration used by pon(1) and poff(1).
# See the manual page pppd(8) for information on all the options.

# There should be a matching entry with the password in /etc/ppp/pap-secrets
# and/or /etc/ppp/chap-secrets.
#user "myusername@realm"
connect "/usr/sbin/chat -v -f /etc/chatscripts/telit-usbmodem"

# Serial device to which the modem is connected.
/dev/ttyACM0

# Speed of the serial line.
115200

# Assumes that your IP address is allocated dynamically by the ISP.
noipdefault
# Try to get the name server addresses from the ISP.
usepeerdns
# Use this connection as the default route.
defaultroute

# Makes pppd "dial again" when the connection is lost.
persist
holdoff 30
maxfail 0

# Do not ask the remote to authenticate.
noauth

debug

chatscript:

# You can use this script unmodified to connect to cellular networks.
# The APN is specified in the peers file as the argument of the -T command
# line option of chat(8).

# For details about the AT commands involved please consult the relevant
# standard: 3GPP TS 27.007 - AT command set for User Equipment (UE).

Странная вещь ... на прошлой неделе это работало просто отлично. Ноль модем зависает ... Любая помощь будет высоко ценится. Спасибо.

Это закончилось тем, что проблема с моим MVNO была подготовлена и была решена. Вышеуказанные конфигурации pppd и chatscript работают просто отлично.

Я не на 100% знаком с PPP, поэтому я не уверен в исправлении, но ваша ключевая линия:

Jul 1 18:05:03 ubuntu-host pppd[783]: Protocol-Reject for 'Compression Control Protocol' (0x80fd) received

Похоже, что провайдер отклоняет запрос на сжатие. Возможно, если вы отключите сжатие, оно будет работать.
