Estoy trabajando en una máquina Ubuntu 12.04 y me vendría bien un poco de ayuda para establecer una conexión ppp con mi ISP a través de un módulo mPCIe Telit HE910.
configuración de 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).

Lo extraño es que... la semana pasada, esto funcionó bien. Cero cortes del módem... Cualquier ayuda será muy apreciada. Gracias.
Respuesta1
Esto terminó siendo un problema de aprovisionamiento con mi MVNO y se resolvió. Las configuraciones anteriores de pppd y chatscript funcionan bien.

No estoy 100% familiarizado con PPP, así que no estoy seguro de la solución, pero su línea clave es:
Jul 1 18:05:03 ubuntu-host pppd[783]: Protocol-Reject for 'Compression Control Protocol' (0x80fd) received
Parece que el ISP está rechazando la solicitud de compresión. Quizás si desactivas la compresión funcionará.
