 |
|
Want to benefit of the advantages of rp-pppoe or simply want to test another way to set up your Speedtouch USB... Here is a solution.
What you must have ?
A kernel 2.4.20+ which supports :
Asynchronous Transfer Mode protocol
RFC1483/2684 Bridged protocols
PPP over ATM
Alcatel Speedtouch USB support
The bridging tool : http://home.sch.bme.hu/%7Ecell/br2684/dist/010402/brctl-010226.c
RP-PPPoE
Linux-atm
modem_run from Speedtouch usermode drivers.
The firmware.
(facultative) hotplug.
Compile the Kernel :
Here is the list of options you must activate to make things work properly with your Speedtouch USB :
Networking Options
Asynchronous Transfer Mode (ATM) (EXPERIMENTAL) [Y]
RFC1483/2684 Bridged protocols [Y]
Network device support
PPP (point-to-point protocol) support [Y]
PPP support for async serial ports [M]
PPP support for sync tty ports [M]
PPP over ATM (EXPERIMENTAL) [Y]
USB support
Preliminary USB device filesystem [Y]
UHCI (Intel PIIX4, VIA, ...) support [Y]
(This can depend of your USB on-board support. Choose UHCI, OHCI or EHCI, like you'll chose with every kernel. lspci -v can give you the USB support that you motherboard provides.)
Alcatel Speedtouch USB support [Y]
Compile the kernel but don't reboot now (You don't have the proper packages installed and don't know how to set up the connection again  ).
Now you must have the modem_run binary which comes from the speedtouch usermode drivers.
You can get the speedtouch ebuild and skip this section "compile modem_run" and continue to the firmware section.
| Code: | | emerge -v speedtouch |
Compile modem_run :
Download Benoit Papillaut's drivers and compile modem_run with :
| Code: | | ./configure && make && make modem_run |
The firmware :
Get the firmware :
alcaudsl.sys
mgmt.o
and copy it in /usr/lib/firmware.bin
| Code: | | cp alcaudsl.sys /usr/lib/firmware.bin |
(or mgmt.o)
Compile linux_atm :
Now we must get the linux-atm headers to compile the bridging tool
| Code: | | emerge -v linux-atm |
To compile it manually do :
| Code: | | ./configure --prefix=/usr --sysconfdir=/etc && make && make install |
Now compile the bridging tool :
| Code: | cc -o br2684ctl brctl-010226.c -latm
cp ./br2684ctl /usr/sbin |
Compile rp-pppoe :
You can get the ebuild :
or compile it manually :
| Code: | cd src
./configure --prefix=/usr --sysconfdir=/etc && make && make install |
| Code: | | Configure rp-pppoe : |
Type :
The interface will be nas0, not eth0.
Now you can reboot on your new kernel.
Final step :
If it boots fine, type :
| Code: | modem_run -k -f /usr/lib/firmware.bin
br2684ctl -b -c 0 -a 0.VP.VC
adsl-start |
You must replace VP and VC by correct VPI and VCI values.
You can look at this :
http://www.linux-usb.org/SpeedTouch/faq/index.html#q12
Maybe will it help you
If all worked fine, you should be connected else, be sure to have compiled the speedtch driver in built-in.
If not load it before launching the bridgle control.
If you launched the bridge control before loading the module, unplug and plug the modem again. Restart modem_run
And launch the bridge control process.
Note : That will not work with 2.6-test6 which KP when you kill modem_run. At least on my box it does.
Note2 : I didn't get hotplug working so if you a know a way that works, let me know

Many thanks for this guide! For some reason, most of the discussion of this modem on these forums has been centred around pppoa, not pppoe. In any case, I now have my speedtouch usb modem working very well.
A few notes. First, I'm using the firmware from speedtouch.sourceforge.net/files/firmware.bin, as described in the pppoa guides (e.g., this one). Possibly as a result, I have to specify boot code (included with the speedtouch package) when using modem_run:
| Code: | | /usr/sbin/modem_run -k -a /usr/share/speedtouch/boot.v123.bin -f /usr/local/lib/speedtouch/firmware.bin |
Second, I don't get a kernel panic when killing modem_run; I'm using a kernel from development-sources-2.6.7. (Haven't tried hotplug.) On the other hand, I'm using a laptop, and the modem doesn't seem to work after a sleep/wake cycle, even if I unplug and replug the modem -- I have to reboot between connections, it seems. (A minor inconvenience compared to using an analog modem.  )
Finally, all this is working on ppc. My laptop is an iBook 2.3 (G3 800 MHz). |

Well in order to use the modem after you unplug it and plug it back in, you need to kill off the bridge and remove the kernel module. I made a simple script to do this:
| Code: |
#!/bin/bash
echo "Attempting to disconnect..."; adsl-stop
echo "killing bridge..."; ps xu | grep br2684ctl | grep -v grep | awk '{ print $2 }' | xargs kill -9
sleep 2
modprobe -rf speedtch
|
Note: for this to work you need module unloading + forced module unloading enabled in the kernel.

Thanks for the tip! That works perfectly, even without forced module unloading enabled ('modprobe -r speedtch' seems to work fine). |
