Good day, (please excuse the long post)

I need to get a GPRS connection to a public APN on a cell phone
network going. ( Later on to a private APN )

1.) I am running Slackware 10.2 on an embedded system and use a PC104
based GPRS modem with a Wavecom module.

2.) The modem is set up as follow

AT+CGDCONT=1,"IP","internet"
AT+CGATT shows that the modem is attached and AT+CGREG show that
the modem is registered

3.) I have set up my /etc/ppp/options file as follow:

nodetach
noauth
debug
kdebug 7
crtscts
name "internet"
connect "chat -vs ECHO OFF\r '' AT\r OK ATE0v1\r OK ATDT*99***1#
CONNECT"
novj
nomagic
asyncmap 0
defaultroute
usepeerdns

4.) When I run the file I get the following result:

root@DeathStar:/etc/ppp# pppd ttyS1 115200 file /etc/ppp/options
send (AT^M^M)
expect (OK)
AT^M^M
OK
-- got it

send (ATE0v1^M^M)
expect (OK)
^M
ATE0v1^M^M
OK
-- got it

send (ATDT*99***1#^M)
expect (CONNECT)
^M
^M
CONNECT
-- got it

Serial connection established.

Modem hangup

It appears that the modem is connecting, but I have authorization
issues here?
Does anybody have any pointers?

Thanks in advance any help will be appreciated.

NB: by using the 'noauth' option, you only disable /your/ checking of /
your providers/ credentials. This does not control whether or not your
provider will want your credentials.

The other end wants you to authenticate (log on) using PAP

Your PPP refuses to authenticate with the other end using PAP

The other end falls back and asks you to authenticate (log on) using
CHAP

> No auth is possible

Your PPP refuses to authenticate with the other end using CHAP

And again, they want you to log on using PAP, but you refuse

At this point, they give up. Since your PPP doesn't want to
authenticate, and your provider won't let you on until you do, they
(your provider) simply declines to continue the conversation.

After struggling with my options file I got it semi-working. (at last)

It appears that I am connecting but I can not ping any machine.

The output when running my script is:

Serial connection established.

Tx packets: 2 errors: 0 dropped 0 overuns: 0 frame: 0
colllisions: 0 txquelen: 3
Rxbytes 32 (32.0b) Txbytes 32.0b)

when running route -n i get:

Destination Gateway Genmask Flags Metric Use ID Ref
85.102.119.136 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0

0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 pp0

This lead me to believe that my pppd is up and running. (but I am
concerned that I do not have a default entry in the route table, that
is a requirement according to the PPP-Howto.?)

Any pointers as to what I can check? Any help will be appreciated.

TIA

In your /etc/ppp/pppoe.conf file, make sure that
DEFAULTROUTE=yes
is set.

Thank you, to everybody that responded it is working!
