This tutorial is written for anyone who wishes to use Eircom I-Stream with the SpeedTouch USB Modem from Alcatel. I got this to work on Debian 3.0 with a 2.4.18 kernel. So please note that all later 2.4.X kernels now come with bridging/pppoe support and the alcatel speedtouch usb modem driver all built in to the kernel. As such the patching of the kernel and compiling of the speedtouch module as mentioned in the tutorial are no longer a necessary step. Before we begin here are the packages you will need to get this working. For The Hardware:
The speedmgmt application from Alcatel; http://www.speedtouchdsl.comThe Open Source Kernel Module written and maintained by John Verrept; http://linux-usb.sourceforge.net/SpeedTouch The SARLib; http://sarlib.sourceforge.net A linux kernel, 2.4.2 or above.; http://ftp.kernel.org/pub/linux/kernel/v2.4 For PPPoE:
A PPPoE aware daemon; http://skyhawk.redbrick.dcu.ie/Adsl/ppp-2.4.0-pppoe4.tgzThe RFC2684 Bridging kernel patch and configuration utility http://skyhawk.redbrick.dcu.ie/Adsl/br2684-against2.4.17.diff http://skyhawk.redbrick.dcu.ie/Adsl/brctl-010226.c The versions I used of these packages are available here Firstly you must patch the kernel:
Change to the directory where you will be untarring the kernelcd /usr/src Untar the kernel source: tar zxvf linux-2.4.x.tar.gz Your source may be in .tar.bz2 format If so do this bunzip2 linux-2.4.x.tar.bz2 tar xvf linux-2.4.x.tar Now to apply the PPPoE patch: cd /usr/src/linux patch -p1 -s -E < /pathTo/br2684-against2.4.17.diff Now you must configure the kernel: choose your preferred kernel config program e.g make menuconfig, make xconfig The Following options must be set for the adsl to work:
Code Maturity Level OptionsPrompt for development and/or incomplete code/drivers [Y] Loadable Module Support Enable Loadable Module Support [Y] Processor type and features Symmetric multi-processing support [N] Networking Options Packet Socket [Y] Asynchronus Transfer Mode (ATM) (EXPERIMENTAL) [Y] RFC 1482/2684 Bridged protocols [Y] Network Device Support PPP (Point-to-Point Protocol) Support [Y] PPP Deflate Compression [Y] PPP over Ethernet (EXPERIMENTAL) USB Support Support for USB [Y] Preliminary USB Device Filesystem [Y] UHCI (Intel PIIX4, VIA,...) Support [M] OHCI (Compag, iMacs, Opti, SiS, Ali,...) support [M] NOTE:These are merely the options needed to get the adsl functioning Don't forget to select the other modules needed for your systems correct operation. Once your selections have been made save your new kernel configuration and compile your new kernel. make dep make bzImage make modules make modules_install make install If all goes to plan you should now have a new kernel. Reboot for the changes to take effect. On reboot type uname -a to verify the new kernel version. Next the Speedtouch module must be compiled: Untar and build the SARLib: tar xvzf sarlib-0.2.x.tgz ln -s sarlib-0.2.x sarlib cd sarlib make Now the SpeedTouch module: tar xvzf speedtouch-1.x.tar.gz cd SpeedTouch make make install You should now have the required kernel module. Next we need to install the Binary Management Application: tar xvzf speedmgmt-1.x.gz cd mgmt cp speedmgmt /usr/sbin DO NOT compile these files, we only need the firmware application itself. Next you need to install PPPoE support: Firstly the ATM Package: tar xvzf atm-0.78.tar.gz cd atm make make install Next compile the br2684 utility cc -o br2684ctl brctl-010226.c -latm cp br2684ctl /usr/sbin Lastly install the PPPoE daemon: tar xvzf ppp-2.4.0-pppoe4.tgz cd ppp-2.4.0.pppoe4 ./configure make make install That completes the installation of the required packages. Now all thats left is to configure the system. Configuring the usb system Add this line to /etc/fstab /dev/usb /proc/bus/usb usbdevfs defaults 0 0 This will mount your usb filesystem at boot-time Configuring PPPoE Edit your /etc/ppp/options file and replace it with: lock defaultroute noipdefault noauth passive asyncmap 0 name yourIstreamName@eircom.net user yourIstreamName@eircom.net lcp-echo-interval 2 lcp-echo-failure 7 plugin /usr/lib/pppd/plugins/pppoe.so nas0 Next edit /etc/ppp/chap-secrets and /etc/ppp/pap-secrets and add the following "yourIstreamName@eircom.net" * "yourIstreamPass" And finally testing the system: Make sure your usb modules and speedtouch modules are active type modconf go to /kernel/drivers/usb and select the speedtch module and your required usb module/s Verify the modules have taken by typing lsmod. Now the moment of truth Firstly bring up the Ethernet bridge br2684ctl -b -c 0 -a 8.35 Next bring up the nas0 interface ifconfig nas0 up Now initialise the modem with the binary application speedmgmt And lastly initialise your ppp daemon pppd IF all goes well you should see the following in /var/log/syslog pulsar pppd[245]: Plugin /usr/lib/pppd/plugins/pppoe.so loaded. pulsar pppd[245]: PPPoE Plugin Initialized pulsar pppd[246]: pppd 2.4.0 started by root, uid 0 pulsar pppd[246]: Sending PADI pulsar pppd[246]: HOST_UNIQ successful match pulsar pppd[246]: HOST_UNIQ successful match pulsar pppd[246]: Got connection: f41 pulsar pppd[246]: Connecting PPPoE socket: 00:02:3b:01:de:88 410f nas0 pulsar pppd[246]: Using interface ppp0 pulsar pppd[246]: Connect: ppp0 <--> nas0 pulsar pppd[246]: Remote message: CHAP authentication success, unit 38 pulsar pppd[246]: local IP address 159.134.96.31 pulsar pppd[246]: remote IP address 159.134.96.1 CONGRATULATIONS your adsl line is working. There are a lot of ways in which things can go wrong whilst attempting this. It took me countless recompiles and reboots to finally get it going. If you are having problems feel free to drop me a mail and hopefully it's an error that I may have come across during my ordeal in getting this working. About the author, Declan McMullen.
