NETWORKING-DSL with PPPoE

From: David McKeever <firstname.lastname@example.org>
My system is a 'stand-alone' , meaning that I'm not a FTP or mail server; I surf and get my mail off the internet when I'm not playing chess online or playing around with Linux. My computer uses a 400 Celeron CPU, and I have both Windows 98 and Caldera Open Linux 2.3 (with KDE) as my operating systems. I'm assuming that the reader already has their home wird for telephone and the DSL installer provided a pots (plain old telephone service) splitter or filter; if the help you are looking for is more oriented to the hardware aspect of DSL try 'ADSL How To' at http://www.sushisoft.com/adsl/ .This SxS may not work with your system and might present a security risk.
I had problems getting connected on my Southwest Bell DSL,
the main problems being getting the right numbers in the right
places, and most of all of getting a script that would allow me
to log in to my ISP. I've heard the claim that you are
connected all the time with DSL, but that isn't always
true. There is a login protocol called PPPoE (Point to
Point Protocol over Ethernet) that logs in and authenticates
similar to a dial in ISP. I have managed to find a web
site that offers a program using PPPoE , and within 5 minutes
after of downloading it I was on the Internet. I'm not
sure after finding this program that the first 4 or 5 steps are
necessary; if someone jumps to step 6 and it works (or doesn't)
please let me know. In these steps I ommitted mentiong
saving changes, opening and closing dialogue boxes, xterm
windows and other steps that seemed obvious to me. I
should also say that the rp-PPPoE software offers and installs
a firewall (actually 2: 1 is for FTP or mail servers) and which
the program creator strongly recommends installing.
1. Make sure that your Network card is installed correctly, has been detected and identified by your Linux system, and the appropriate modules are loaded and enabled. If you just installed your card, go to COAS > Kernel and you wil be probed (not painfully!). On mine the Kingston EtherRx 10/100 PCI Fast Ethernet Adapter provided by SWBell was recognized and the 'tulip' driver was loaded and enabled at boot time.
2. I went to COAS > Network > Ethernet Interfaces and configured the dialogue box like this (from Arnie Sherman's SxS):
Network Device: eth0
PNP Configuration: Disabled
Interface address: 10.0.0.2 (it changed to 10.0.0.0 after I got it working)
Network mask: 255.255.255.0 (it changed to 255.255.0.0)
Broadcast address: 10.0.255.255
Default route: Disabled
Default gateway: Shaded out when disabled
Init at boot time: Enabled
3. I went to COAS > Network> TCP/IP > Resolver and added the two numbers that were provided by SWBell. There are so many numbers involved that it can confuse; these numbers seem to come in pairs; primary and secondary (the Domain Name Server translates name addresses into numbers and vice versa).
5. I went to Internet > Network Utilities and pinged 10.0.0.0 and somtimes it worked and somtimes it didn't (trying a lot of different numbers). The main thing was to make sure the NIC (Network Interface Card) was working, and I was sure it was because I could use the 'ifconfig eth0 up' command (as su and without quotes) and this would indicate that I had the card working (also using the 'netstat -nr' and 'ifconfig'). But still no connection, even when it was pinging something somewhere (my own machine most likely), so I used my dial up ISP which I still have running and browsed around until I found:
6. http://www.roaringpenguin.com/pppoe.html Here I downloaded the rp-ppoe-1.8.tar.gz file which I recall can be download as an RPM, and issued the following commands from a terminal window:
and an interacive dialogue up requiring some of the same information I indicate above, then
adsl-start (as su)...and I was on.
This program is well documented; someone having problems
could open the read me's and troubleshooting
guides. The info indicates that the latest ppp is
necessary, and of course the pppd (d for daemon) must be
running. More information is available from these SxS's
for links and more info on PPPoE.
