I already posted this request of help to the debian-laptop mailing list,
but couldn't get help. Maybe someone on this forum?

I'm trying to connect to internet with a gprs cellular phone, a Motorola c350,
connected to my laptop Hyundai 255KI 15 with a mini usb cable.
Debian Sarge 3.1 is installed.
I've been following the howto at:

http://www.debianitalia.org/modules/...1&articleid=96

. First I made sure the acm driver was there, with:

# dmesg |fgrep acm

. Then I did:

# mknod /dev/usb/ttyACM0 c 166 0

. Then I created a file /etc/pppd/peers/provider and filled it with:


# Speed
115200
# Use hardware flow control (i.e. RTS/CTS) to control the flow
# of data on the serial port.
crtscts
# Use the modem control lines.
modem
# Specifies that pppd should create a UUCP-style lock file for
# the serial device to ensure exclusive access to the device.
lock
# Disable Van Jacobson style TCP/IP header compression in both
# the transmit and the receive direction.
novj
# Disables the default behaviour when no local IP address is
# specified, which is to determine (if possible) the local IP
# address from the hostname.
noipdefault
# This option causes pppd to create such a default route when
# IPCP comes up, and delete it when the link is terminated.
defaultroute
disconnect '/usr/sbin/chat -e -f /etc/chatscripts/disconnect -v'
connect '/usr/sbin/chat -e -f /etc/chatscripts/provider -v'
/dev/usb/ttyACM0
user anything
password anything
#With this option, pppd will accept all control characters from the peer, including those marked in the receive asyncmap
receive-all
logfile "/var/log/pppd.log"
nobsdcomp
nodeflate



. Then I created a file /etc/chatscripts/provider and filled it with:


'' AT
TIMEOUT 240
OK 'AT+CGDCONT=1,"IP","web.omnitel.it"'
OK ATDT*99#
TIMEOUT 22
CONNECT ""

. Then I put "noauth" in place of "auth" in the file /etc/ppp/options.
Then I tried to connect with '# pon', but it couldn't be established.
I put the line 'debug' at the end of the file /etc/ppp/peers/provider
and this is /var/log/pppd.log:

AT+CGDCONT=1,"IP","web.omnitel.it"

. Does anybody have any idea about what the problem should
be and how to work it out?
Thanks indeed,

First, if you really want expert information, go there:
comp.protocols.ppp
James Carlson is helping thousands of people and he knows a lot about ppp. This problem is not at all related to debian.

Do you do a ctrl c or killall -15 pppd there or is this your problem?
If it is you, then try to stay at least 1 or 2 minutes to see if the server send you Authentification Failure messages.

I don't see any problem in your pppd.log and you should not be far from connecting.

What is the result of this:
*from the machine where the ppp client is*, not from your lan!

This is exactly my problem: the line 'Terminating on signal 15'.
The connect time 0.3 minutes is because I close the connection since
I cannot navigate.

# ping 192.168.100.101
connect: Network is unreachable

Thanks indeed,

Oki

try to connect

*WAIT 1mn* Depending on the timing with gprs/ authentication of gprs which violates the ppp standard, it can be slow

And then post the output of

and of

I'm not here for several days , so either you have the chance to be helped by someone here or you explain clearly your problem on the mailing list I provided before (you have a lot of chance to solve the pb there)

ciao

Here are the outputs of '# route -n'

. Bye,

Your route seem ok.

My idea to ping 192.168.100.101 was not good I think because this adress is a non routable adress and your ppp server can't contact it.

What gives this:
(ip adress of www.google.com)

Then you have to get ppp to send you your dns servers, there is no line
ms-dns in your ppp transaction so maybe your /etc/resolv.conf was not updated and you can't use host names.
Try adding this line in the pppd option file:
and then

manually feed in the gateway address of your ISP

also try

#nslookup <isp nameserver IP address>

#dig yahoo.com

I did so, and seeems that the problem is solved now:
I wrote a complete report at:

http://lists.debian.org/debian-user/.../msg00017.html

Very nice of you to do a Howto. I may have to read it one day.

Cheers
