3g ppp - PC-BSD Forums

mettw · #1 05-10-2012, 02:13 AM

I have a 3G modem (Maxxon bp3) for telstra in Australia and I am completely lost as to how I am supposed to start a connection with it. I installed PCBSD from the CD.

In Network Configuration I set everything up as it should be, and judging by Linux it should be on the device cua0.1. So how do I actually start a connection? There is nowhere to enter a phone number, no ppp utility that I can see, and nothing in the manual about it.

What am I supposed to do to get PPP started?

You'll need to edit /etc/ppp/ppp.conf by hand most likely. At the moment
we don't have any developers who are using PPP over 3G to test / fix
this functionality in the GUI.

OK, Thanks. I just assumed there would be some Ubuntu like utility.

One more question, on my Debian system authentication is done through an AT command of:

AT$QCPDPP=1,1,"password","username"

On BSD is this sent to the modem automatically by the

set authname foo
set authkey bar

lines?

Do you know how I would go about setting the CID and auth type that are also set by this command? I presume PAP must be set somehow, and I can set the CID=1 by dialling *99#, but I was just wondering if FreeBSD used the same method or not. I am no expert on PPP and modems.

Thanks.

During my time with 3G on FreeBSD, I had to interactively send commands to ppp to start a successful connection. These where my steps taken.

Start PPP in interactive mode:

Code:

ppp

Specify the device:

Code:

set device /dev/cuaU0.0

Enable DNS

Code:

enable dns

Specify it to request a remote

Code:

ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0

Code:

add default HISADDR

I normally disable ipv6 stuff:

Code:

disable ipv6cp

Specify timeout to be 0 other wise it disconnects on idle:

Code:

set timeout 0

Now enter a terminal prompt to send commands to the device:

Code:

term

For finding out what commands to send to the modem, I used wvdialconf to probe the modem under Linux and wrote down the commands which were the following:

send the commands to the device:

Code:

ATZ
ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
AT+CGDCONT=,1"IP","three.co.uk"
ATDT*99\

Then type ~/ to return back to PPP. Then simply type:

Code:

dial

This got me up and running with 3G on FreeBSD. there wasn't much documentation on it, so took me awhile. hopefully you find this useful.

I got internet running through internet connection sharing with my windows laptop so I stopped messing about with this for a while. But I have finally got my 3g modem to work on PC-BSD.

There is something very weird going on with connecting to the modem with PPP. Most of my problem before was that I couldn't even get a term session in PPP to send AT commands. Even now it is unreliable. Sometimes it just can't get a term session and I have to try it a number of times or else switch the modem off and on again.

This is what I had to do to get it up and running. Some of this might be redundant - This is my first connection with it.

ppp.conf

Code:

default:
  set timeout 180
  set device /dev/cuaU0.1
  set dial

telstra.bigpond:
  enable dns
  set authname USERNAME
  set authkey PASSWORD
  set login
  set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
  add default HISADDR

Then in PPP I entered:

Code:

>set timeout 180
>set device /dev/cuaU0.1
>set dial
>term
Failed to open /dev/cuaU0.1
>term
