I Contents

This archive contains several scripts useful to avoid Wanadoo's ADSL disconnections every 24 hours
They consist of :

ChangeLog       - well let's give a real history to araw ;-)    
README          - a strange file, I don't know its use or even how it got
                there...
araw-down       - a custom script to perform operations after pppd has been
                killed
araw-up         - a custom script to perform operations before pppd is run
install.sh      - the installation script, you'll have to edit this to fit your
                system
ip-up           - an ip-up script (man 8 pppd for info) which starts the
                connection-is-up checking script.
ip-check        - THE connection-is-up checking script which will automatically
                reconnect if it can't get to ping it's gateway at Wanadoo's.
ppp-at          - a little line launched using the at daemon to make sure the
                pppd is correctly launched.
ppp-go          - a verification script which checks wether pppd has started
                correctly (and hasn't killed itself). 
ppp-kill-at     - the "core" of the IP keeping feature
rc.adsl         - a startup script which configures Alcatel's Speedtouch USB
                with Benoit Papillault's driver
                (http://speedtouch.sourceforge.net) and launches the ppp daemon.
routing-down    - a custom script to perform operations like heavy iptables'ing
                before pppd is killed
routing-up      - a custom script to perform operations after pppd has be
                started

II Installation

To install this collection of scripts, just unbunzip2tar this archive wherever you want. Next you have to edit the install.sh script for the paths to match those on your system (pppdir, startupdir, rclocal, mrunpath, mgmt). Finally just launch instal.sh as root.

The install.sh now has back-up functions, if one file FILENAME previously existed, it is renamed to FILENAME.old.DATE, where DATE is the output of "date +%Y%m%d%H%M%S" at the time ths install.sh is run

III Compatibility

I have personnaly successfully used this script to connect to Wanadoo (France). It was originally written for Slackware 7.1/8.0 systems and hasn't been tested elsewhere.

It has also been reported to work with:

• Club Internet's ADSL
• Wanadoo and Debian 3.0r0

IV IP keeping

This feature (disabled by default, check the ip-up file) tries to keep the same IP for your box even after a dis/reconnection cycle. In fact it will kill -HUP the ppp daemon. Make sure you have specified "persist" in your options file (probably /etc/ppp/options or /etc/ppp/peers/adsl). When sent a SIGHUP, pppd will close the connection and, provided the persist option has been given, it will reinitiate one, asking the Wanadoo's DHCP for a new IP. The trick is that Wanadoo's DHCP seems to have 24 hours leases. This way, killing the pppd every 12 hours will make it reinitiate the connection and request a new IP, which will be the same as 12 hours ago... Of course, don't hope to get the same IP back after having had your box shut down for some time.

This feature is directly copied on an idea of Nicolas Pouillon, which proved to work.

As of version 0.4, it's the first implementation of this function into araw so don't be too demanding, it may not work.

V Other notes I don't know where to put them

Remember the driver of your modem should be correctly installed before trying to install ARAW, the install.sh file doesn't handle this (harrasing) part and probably never will...

The provided files are not directly usable... You must use the install.sh script which will edit and addapt the files to your system (using the information YOU provided).

This set of scripts relies on quite an old version of the Speedtouch's driver, but I didn't have the occasion to work on a newer version. This occasion will probably happen during June/July 2002.

If you have any comments on or modifications to add to this script, well, my mailbox is not /dev/null yet :-).

VI Thanks

I would like to thank :

• Nicolas Pouillon for his explanation on his ip-keeping feature
• Mathieu Ruellan for his advice which lead to ARAW v0.5
• Nicolas Deves for his remarks about bugs in the install.sh script
