 UPDATED 28.jan.2005 Complete step-by-step HOWTO for configuring PPPoE for ADSL (ST DSL)

Before you start

Run Vigor 318 Control panel (or ask your provider) for these parameters: sample adsl configuration parameters


Applying patch to kernel

Copy and unpack kernel to some directory (example: /usr/src/linux-2.6.10-custom)
Edit Makefile in this directory 

VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 10
EXTRAVERSION = -custom
enable the following modules with "make gconfig", "make xconfig" or "make menuconfig":

Device Driver -> Networking Support -> Networking Options -> ...
<M> Asynchronous Transfer Mode (ATM)
<M> Classical IP over ATM
[*] Do NOT send ICMP if no neighbour
<M> LAN Emulation (LANE) support
<M> Multi-Protocol Over ATM (MPOA) support
<M> RFC1483/2684 Bridged protocols
[*] Per-VC IP filter kludge
   
Device Driver -> USB Support -> ...
<M> Support for USB
<M> Alcatel Speedtouch USB support (NEW)
Compile kernel: 
make
make modules
make modules_install
make install
Reboot machine with new kernel

You need to install these packages or newer (or compile from source): If you want compile ppp-2.4.2 from sources you have to install also these before If are compiling libpcap from sources you will also need byacc and flex

unzip and copy patch to ppp-2.4.2 directory and apply patch by typing 
patch -p1 < ppp-2.4.2_poa_poe_patch_20040611
and also do modification in two files:
edit ppp-2.4.2/pppd/demand.c and replace
#include <net/bpf.h> with #include <pcap-bpf.h>
the same change do for ppp-2.4.2/pppd/syslinux.c

after that compile pppd-2.4.2 as usual (make; make install)

Unpack cxacru to some directory
Download cxacru-vigor-update.tar.gz and replace these cxacru files. Then compile cxacru from source by typing 
make
make install
After that you must remove these files
/lib/modules/2.6.10-custom/kernel/drivers/usb/cxacru.ko 
/lib/modules/2.6.10-custom/kernel/drivers/usb/cxacrudbg.ko 
/etc/ppp/options
BTW: Because speedtch.ko instead of cxacru.ko and pppoe.conf instead options will be used.

Edit /etc/cxacru like this 
DRIVER_MODE=1  # 1 = normal, 2 = debug, 3 = normal+max speed (without ask adsl status), 4 = debug+max speed (without ask adsl status)

# Protocol
PROTOCOL_MODE=4  # 1 = RFC1483/2684 routed, 2 = PPP over ATM (pppoa), 3 = RFC1483/2684 bridged, 4 = PPP over Ethernet (pppoe)

# Paths
BINARY_PATH="/usr/sbin"
ATM_PATH=""

# ADSL
#  if OPEN_MODE is blank then cxload uses default mode acoording VID & PID
#  Values for OPEN_MODE are:
#    0 = auto selection, G.Handshake
#    1 = auto selection, T1.413
#    2 = G.Handshake
#    3 = ANSI T1.413
#    4 = ITU-T G.992.1 (G.DMT)
#    5 = ITU-T G.992.2 (G.LITE)
OPEN_MODE=4

# ATM
VPI=1
VCI=32

# Specific for RFC1483/2684 routed/bridged
#  if IP_ADDRESS is blank in bridged mode then it uses DHCP to get IP
IP_ADDRESS=
NETMASK=255.255.255.0
GATEWAY=

Run /usr/sbin/adsl-setup and type 
Username:  	your_login@dslbasic.stonline.sk
Interface: 	nas0
DNS: 		server
PPPoE password: your_password
Firewall:	0 or 1 or 2
Start this connection at boot time: yes or no

To start connection run cxstart.sh
Sample log file of successful connecting/disconnecting.


FAQ

Question:
I'm getting this error when run cxstart.sh 
RFC1483/2684 bridge: Interface "nas0" created sucessfully
RFC1483/2684 bridge: Communicating over ATM 0.8.35, encapsulation: LLC
RFC1483/2684 bridge: Fatal: failed to connect on socket
Answer:
Use modified script cxnet4up.sh which executes cxioctl before br2684ctl
Question:
I'm getting TIMEOUT, but ADSL line is up (orange LED is lighting)
Answer:
Run adsl-connect and wait until authentificated,
after that you can terminate script (because interface is mapped) and you are connected successfully.
