Hi,

while I was trying to do a pppd dial-up through a 3G modem, the following messages

keep poping up on my console.

and ifconfig did not show any ppp0 interface (think the dial-up fail but I don't know how to check).

[   67.203918] slhc: exports duplicate symbol slhc_toss (owned by kernel)
[   67.230133] ppp_generic: exports duplicate symbol ppp_unregister_compressor (owned by kernel)
[   67.278167] slhc: exports duplicate symbol slhc_toss (owned by kernel)

[   70.404815] slhc: exports duplicate symbol slhc_toss (owned by kernel)
...

can anyone help ?

I am using kernel 2.6.29 with Angstrom distribution.

Thanks!

In fact, that is another issue I face.

In my ubuntu pc, I can use plog to see the pppd progress, or look at the log at /var/log/syslog.

In beagleboard however, there's no plog, and I could not find the syslog as well.

Any idea how to enable one of those ?

p/s: I was using OE to build this Angstrom distribution.

No idea how to enable those. I also did this under Angstrom. What I did
was to use the command line to tell pppd where I wanted it to put its log
then view the log with cat ppplog.txt |more

Just wanted to clarify that the log was called ppplog.txt because that is
what I told pppd to name it. Not sure what it is by default.

Do you know what is causing the "LCP terminated by peer (M-O^J)" ?

I used the same scripts "tr900-m1" in PC and it was working fine. but why not in beagleboard ?

A Google search for "LCP terminated by peer" turned up some stuff that may
or may not help you. You might have to wait until someone that knows more
about the kernel modules can tell you if that is the problem.

You can try lsmod to see if the ppp_generic and slhc modules are there.
You can also try to look in /proc/config.gz to see if they were compiled
into the kernel, but I don't think they would be by default.

That's about all I know.

David.

Try turning on debug via the command line i.e.
pppd debug logfile /tmp/pppd.trace nodetach call FOOBAR

Take a look at /tmp/pppd.trace afterwards and see what it is unhappy about.

You could also take a peek at the slides I did for a quick talk on PPP
debugging. They are in my downloads section of my webpage.

That is one possibly. Remove the "usepeerdns" and see if it helps.

Based on your trace, the other possibilities are -

Your init string is wrong and you've connected to a service you are not
authorized for. Check your chat script and compare it to a working setup.

The username/password you have use may not be setup for IP traffic. Or you
have manage to confuse the other end with your choice of to refuse CHAP.

Unfortunately, there are no standards for these things; each carrier is
different. Even within a carrier there are differences depending on your
billing details and/or history. (i.e. for Tmobile US, there are different
settings depending on what plan you are on; for ATT US, it can vary depending
on if you were an orange or a blue customer originally, etc.)

Hi,

thanks guys! the pppd finally works on my beagleboard with usb connection to a Huawei E220 modem.

It was indeed some misconfiguration in my chat connect script that cause the remote server to refuse the connection.

I may send my chat config files to you if anyone of you are interested.

And the kernel messages reported earlier does not seem to cause any harm... at least for now :)

[ 67.230133] ppp_generic: exports duplicate symbol ppp_unregister_compressor (owned by kernel)

Thanks alot Tomas,
Today I'm just able to communicate over UART with 3g SIMCOM SIM5218E

Below is the output, however no response to any keypress/data from the

This is not a Beagle board problem.

Your SIM has a "PIN lock".

You should add a command like AT+CPIN=2311 before continuing with ATD
command (change 2311 to your PIN).

I encountered this issue previously when the modem was not hang up properly from previous connection.

Same thing may have happened in your case:

You may want to make sure the modem was neatly hangup before attempting to dial up again.

Good luck !

I recenly able to connect to internet with my leopardboard.
There was 2 problems, first was I somehow disabled RF transmission on
the modem, and the second was OK AT+CGDCONT=1,"IP","mgd" was wrong. I
changed it to "mgd" then everything worked like a charm.

Thanks a lot thomas for the ppp config scripts.

Hi Thomas,

I am also trying to connect 3g usb modem to Beagle Board -Xm Angstrom distribution running on it. With help of your script it worked fine. After working few day it was not connecting through pppd connection. Same USB 3G modem working fine on the other BB-Xm with same setting on the SD Card.

it was loading ppp drivers fine...
