I am using worldnet.  When I joined, there was an entry on the wurd
site (don't remember the link right now) that provided a perl script
written by an ATT employee.

Yes, I would appreciate it  very much if you would Email the perl
script to me.  I think it is exactly what I need.  Thanks.

Bill, etal
Here is a copy of my ppp script (/usr/sbin/ppp-on - it has also been
called ppp-worldnet!!). I have also attached the html page that all of
this came from - courtesy of ATT. - some good notes.
Special thanks to Stephen A. Wood - I tried to contact him at ATT a
while ago, but no such luck!! As far as I'm concerned, he deserves a
big thank you.

$ENV{'PATH'} = ''; # Make $ENV{'PATH'} untainted
system($command);

The lines 8-12, and 17-26 are  commented out on my SuSE machine and the
necesary data put in resolv.conf permanently - documentation recommended
against frequent updates because of the way SuSE sets things up.

If its not clear what I've done here, email me and I'll try to explain.
 The html doc has a good explanation though.
 Have a good day, everyone.

            <p align="left">AT&T's Worldnet Service uses
            standard PPP (Point-to-Point Protocol) with CHAP
            (Challange Handshake Authentication Protocol). While
            Windows 3.1x or Windows 95 is required to register a
            new account, other operating systems that support PPP
            with CHAP can be used once an account is registered. </p>
            <p align="left">Unless you have already configured
            your Linux system to use PPP to another Internet
            Service Provider, connecting to Worldnet from Linux
            will take a little bit of work (recompilling the
            Linux kernel). Here are a few <a href="whylinux.html">here

            notes</font></a></h2>
            <p align="left"><font size="3">If you are already
            using PPP to other ISP's there are essentially just
            two possibly new things that need to be done. First,
            since Worldnet uses CHAP, you must put your username
            and password (as found in REG.INI) into the file <tt>/etc/ppp/chap-secrets</tt>
            like so: <code>999999999@worldnet.att.net *
            "password" * </code></font></p>
            <p align="left"><font size="3">Secondly, the chat
            script should only go as far as getting the phone
            dialed in. CHAP will take care of passing username
            and password. For example: </font></p>
            <div align="left">
            <pre><font size="4"><code>usr/sbin/pppd name "999999999@worldnet.att.net" -d connect 
'/usr/sbin/chat -t 45 -v ABORT BUSY "" ATDTthephonenumber CONNECT ""' \
/dev/modem 57600 noipdefault debug modem defaultroute crtscts 
</code></font></pre>
            </div>
            <h2 align="left"><font size="4">Additional Notes</font></h2>
            <p align="left"><font size="3">Some people connecting
            to Worldnet with Linux report that it is necessary to
            add the flag <code>+chap</code> to the pppd command
            line. However, in most cases, things will not work at
            all if this flag is used</font></p>
