Slackware, PPPD and GPRS

Hey

i'm struggling my butt off to get my cell phone's GPRS working with
pppd. all is well until after the chat script where the ppp0 should
attach to /dev/modem(dev/sttyS0) then it just sits there.
On the cellphone the GPRS logo shows it's connected but that's about
it. Nothing happens after the chat script. I'm sitting on a windoze box
at the moment so i cant post the chat script and connection
settings,etc. but i'll appreciate any suggestions. oh by the the way
it's a noauth connection, ie. it doesn't need a password/username.

help wld be appreaciated.
thanx

constant meiring

There is no /dev/sttyS0 AFAIK.

To even get started we need the chat and pppd scripts and the chat -v
and pppd debug logs. Add debug to the pppd options and the line
daemon.*;local2.* /var/log/ppp.log
to /etc/syslog.conf, and do "killall -HUP syslogd" to make syslogd
reread syslog.conf. Then try to connect and post exact copies of
the scripts and log for the attempt.

(It's likely to be harder than you expect to get things working since
cell-phone PPP implementations are generally not well-written and
different cell-phones require different chat and pppd configurations.)

I wen't through this same problem with Slackware and a AT&T
Wireless phone some time ago. I didn't get very far as they wanted to
use a MULTICAST address (aRGH!) But I can give the OP some clues
1. Most Cell ISPs don't want your username/password in their
authentication sessions. They know who you are based on your SIM card
info. In the case of AT&T your PAP password and username entries
would be set to a NULL entry (I believe use you use an '*' in both
fields of pap-secrets.
If you CAN authenticate and it tries to give you a multicast
addresss. UGH! you would need to read up on the multicasting howto
and possibly modify pppd and the kernal to allow for it.
I got Alltel now for my cellular service and I haven't begun
to figure out how to access this CDMA service yet. Did dial ATD#777
from minicom (as Alltel customer suport said to do). got NO ppp type
login session clues. just a connect message. Suposedly they use BREW
(what on earth is that? An alcholic beverage? one that the coder
drinks during debugging? )

lol!

anyway, thanx for the help. I'm using Vodacom GPRS (vodacom is closely
iffiliated with Vodafone. It's just the south-african version. I knew
about the usr/pwd. The dialup is *99**1*1#. On the fone the GPRS icon
appears, but it doesn't actually connect. Donno why.
