1. Introduction
The main goal of this document is to get your system running with your
cable modem, and cable internet provider. Unfortunately, many ISPs
that provide cable modem services, give you Windows and Macintosh
software only.
This document attempts to explain how to setup some cable modems and
internet providers in Linux, the tricks to get them working correctly,
and the traps not to fall down. It is hoped that this document will
assist you, however we make no claims for the validity of the
information contained within.

2. Setting up your Ethernet Card
All of the setups below use ethernet cards (network cards) to connect
you somehow to the Internet. That is why first we need to check if
your ethernet card is working and most importantly can be used (read
is supported) in Linux. There is a comprehensive Ethernet HOWTO at
if you would like to read it otherwise try this.
Boot into Linux, During boot up a message like this should appear...
eth0: 3c509 at 0x300 tag 1, 10baseT port, address 00 20 af ee 01 23,
IRQ 10.
3c509.c:1.07 6/15/95 becker@cesdis.gsfc.nasa.gov
If you missed it type dmesg.
If you see a message like that you are set and you can go to the next
section. If you can't see a message like this there are two possible
explanations, your ethernet card is PNP (plug-n-play) and you need to
use tools such as isapnptools to get it recognized (I am not quite
sure on this because I don't have a single PNP card so correct me if I
am wrong). The other explanation is that you need to set up your card.
Most cards today come with DOS programs that are used to setup your
card. For example to get my 3COM 3c509 to work all I needed to do is
boot into DOS and use a utility to configure my card. There is usually
a Auto Configure option. If that does not solve your problem try
changing the IRQ for the card using the same utility. I find that
usually IRQs 10,11 and 12 work well. If none of this solves your
problem please read the Ethernet HOWTO referenced above or post to a
newsgroup such as comp.os.linux.setup or comp.os.linux.networking.
3. Regular Cable Modem ISPs
If you think you have the card recognized you have to now look at the
entry for your ISP. I have sorted the information according to a
provider because setups are mostly ISP specific.
3.1. MediaOne Express
MediaOne Express is a Internet cable service provided by MediaOne. The
hardware setup consists of a cable modem produced by LanCity or
General Instruments which plugs into an ethernet card using a 10BaseT
(UTP-45) cable. Assignment of IP addresses and other networking
information is done using DHCP which stands for Dynamic Host
Configuration Protocol. The only thing you need to do is read the DHCP
mini-HOWTO and configure your system appropriately. There is no other
necessary configuration. DHCP mini-HOWTO can be found at
http://metalab.unc.edu/LDP/HOWTO/mini/DHCP.html
Information about MediaOne Service can be found at
http://www.mediaone.com.
3.2. @Home
@Home uses a similar setup to ``MediaOne''. However, there are a few
fundamental differences, outlined by contributors. Since @Home spans
different geographic locations you might get assigned different kind
of equipment and have slightly different kind of setups.
Before you try anything, go to control panel, network, and properties
for your network card. Write down all of the information. You will
need it later.
TCI, the company that runs @Home issues a Etherlink III 3c509b NIC for
all of their customers. What TCI does not tell you is that when they
install your ethernet card, it is in PnP mode. Now in Slakware, if you
uncomment the proper line for this card, everything will appear to be
working fine. There will be no system problems, but the 'PC' light on
your CyberSURFR modem will never turn on. If you are using Slakware,
and are having this problem, reboot in DOS and skip the next
paragraph.
In RedHat 5, your system will have some trouble autodetecting the
card. If you try to pass the paramaters manually, the system will
hang. This should be obvious that your card is not setup properly.
Before wasting anymore time, reboot in DOS (This is a must because as
of 12/25/97, there is no utility written for Linux to turn off PnP and
turn on ISA.)
TCI does not give out a utility disk for your ethernet card, so you
must download the utility from one of 3Com's sites. Here is a link to
3COM's page for driver download.
http://support.3com.com/infodeli/tools/nic/index.htm
Once you have downloaded your driver files you will need to run them
and disable the PNP mode of your network card.
What you've now done will make your ethernet card 'broken' in Windows
95. You'll need to go to Control Panel, Network, and remove the
network card and the adapter. Reboot your computer, and again go back
to control panel. Go to add/remove new hardware, and have it
autodetect. It will automatically setup the correct i/o address for
you. You will most likely need to reboot again. Now you should be in
Windows 95, with the 'PC' light on your cable modem on. You will also
notice that none of your internet applications seem to work, you can't
ping, and you can't resolve DNS. You now must go back to control
panels, network, and click on properties for your network card (not
the adapter). Re-enter all the data you wrote down, and reboot.
With a little luck, your ethernet card should be working in Windows
95, and ready to rock in Linux.
If you live Hampton Roads, VA or Phoenix, AZ you should read a little
note from Mark Solomon
With the @home service in Hampton Roads, VA, it is absolutly
neccessary to run dhcpcd-0.70 (or higher) that supports the "-h"
option to specify the hostname of your computer. Without this switch
the @home dhcpcd server will not assign addresses.
More information on setting up dhcpcd-0.70 and @Home service with
Intel Ether Express cards can be found at
http://www.monmouth.com/~jay/Linux/
Notes for Baltimore, MD and Colleyville,TX:
In Baltimore subscribers are issued Intel Ether Express Pro 10 nics
and a static IP number.
Notes for Milpitas, CA, USA (Joe Byrne byrne@well.com):
@Home service assignes 3Com 509b cards. IP addresses assigned
statically.
Information about @Home Service can be found at http://www.home.com.
3.3. RoadRunner
RoadRunner is an Internet cable service provided by Excalibur Group
(Time Warner). The hardware setup consists of a cable modem produced
by Motorola and Toshiba which plugs into an ethernet card using a
10BaseT (UTP-45) cable. From what I can gather RR uses DHCP for IP
assignment. In order to set up Linux to use DHCP you need to read the
DHCP mini-HOWTO and configure your system appropriately. DHCP mini-
HOWTO can be found at http://metalab.unc.edu/LDP/HOWTO/mini/DHCP.html
If this doesn't work out for you you should check out
http://www.math.uakron.edu/RoadRunner/ for Akron, Ohio and
http://people.qualcomm.com/karn/rr/index.html for San Diego,
California. It might help solve your problem.
Another good site is http://www.vortech.net/rrlinux/.
Information about RoadRunner Service can be found at
http://www.rr.com.
3.4. Rogers Wave
The hardware setup consists of a cable modem produced by LanCity which
plugs into an ethernet card using a 10BaseT (UTP-45) cable.
When the cable modem is installed by Rogers Wave technicians you are
assigned a static IP address. They should also provide you with
information on your subnet mask, router (gateway) numbers and DNS
numbers.
Other information about Rogers Wave Service can be found at
http://www.rogerswave.ca.
3.5. Sunflower Cablevision
This information is provided by Andrew Novick:
"I recently saw your cable modem howto and I have an addition.
Sunflower Cable is a company stricly in Lawrence KS, however we have a
rather large Linux community because of the University of Kansas. On
our local LUG mailing list, we are starting to get more and more
questions on how to configure their linux machine for the cable modem.
It is just regular static addressing, and the modem is made by
Zenith."
To configure your Linux box make sure you get all the pertinent
information from the Cablevision tech support or use these.
╖ IP address: Assigned by SunFlower Cablevision
╖ Subnet mask: 255.255.255.0
╖ Gateway (router) address: 24.124.11.254
╖ Hostname: Assigned by SunFlower Cablevision
╖ Domain name: lawrence.ks.us
╖ Primary DNS server (nameserver): 24.124.0.1
╖ Secondary DNS server (nameserver): 24.124.0.6
Have all those numbers written down before you proceed. To register,
visit
http://www.sunflower.com
To register in the lawrence.ks.us domain contact Stephen Spencer at
gladiatr@artorius.sunflower.com
Under RedHat use Control Panel and Network Configuration to put in
these numbers. Just say Add Interface, Device type=Ethernet, Device
name=eth0 (this is zero not O in eth0) then fill out all the fields.
Then click activate.
In Slackware type netconfig. When you are finished reboot and you
should be up and running.
If this doesn't work make sure you do network card troubleshooting
from the beginning of this document.
3.6. Jones Intercable
This information is provided by Bob Kimble:
Jones Internet Cable supplies a Hybrid cable modem that connects to
your machine / network via 10BaseT ethernet. They provide you with a
static IP address for your machine, and another static IP address for
the modem. The modem acts as a gateway to their network. Your IP
address and the modem IP address are on the same network and have the
same network mask (in my case 255.255.255.0 -- 24 bits). They also
provide two DNS IP addresses which you enter into your configuration.
I just entered the numbers when I installed Red Hat Linux 5 and it
worked like a champ from the beginning. Since then I have configured
my Linux machine to enable IP masquerading and domain name services,
and it now acts as a router for my entire private network. My other
machines are connected via a private network using the addresses
192.168.0.x. They are running Windows 95, Windows NT (Intel and Alpha)
and OS/2. My Linux machine has two IP addresses -- the one from the
cable company and one from the 192.168.0.x private network. Everything
works like a champ. All six machines can browse the web
simultaneously. My kids are even able to connect to their favorite
game site, "The Realm" from Sierra.
3.7. GTE Worldwind
This information is provided by Mike Hughes:
The information you provided for Rogers Wave works for GTE WorldWind
cable modem services also. However, GTE's service is EXTREMELY slow,
barely faster than ISDN. more information at
http://www.psilord.com
3.8. SpeedChoice, Phoenix, Arizona
According to Micah peenchee@asu.edu:
Just thought I'd let you know that in my area (Phoenix, AZ, usa) there
is a company called speedchoice that provides cable modem service.
The service uses a hybrid cable modem and the set up is almost
identical to that of Jones intercable described in the howto. See
``Jones Cable''. For any other issues mail Micah.
3.9. Cedar Falls Cybernet, Iowa
This information is provided thanks to Joe Breu breu@cfu.net
We are an ISP in Cedar Falls, Iowa that uses the Zenith HomeWorks
Universal over our own Hybrid Fiber/Coax system. Our system uses no
proprietary connection software and is straight TCP/IP connections.
We do use DHCP, but will offer static IP addresses to customers
requesting them because they cannot use DHCP.
3.10. Telstra Bigpond Cable, Australia
This information is provided by Geoff Conway
gconway@vic.bigpond.net.au
Disclaimer:
The information contained herein is in no way the responsibility of
Big Pond Cable, Telstra Multimedia, Telstra, IBM Global Services
Australia or any related company. Any loss or consequential damage
associated with the attempted installation of the Big Pond Cable Linux
software is the PERSONAL responsibility of whomsoever follows these
instructions.
Big Pond Cable does not currently support Linux - so do not report
faults to them regarding any aspect of the Linux installation and/or
operation.
Big Pond Cable Linux Installation Notes. V 1.1 (12/03/98)
Change Note 1.1 12/3/98 - Corrected spelling of dhcpcd & rrdhcpcd
Linux is not officially supported by Big Pond Cable. However, the TMM
cable infrastructure does allow Linux to be used - with the
appropriate login client. The following installation notes should
allow you to install the Linux software without too many difficulties.
The full client distribution of rrclientd was obtained from:
ftp://ftp.vortech.net/pub/rrlinux/rrclientd-1.3.tar.gz
I am running RedHat version 5 of Linux - but the documentation
indicates that it will work with other releases.
Note that there is also more information in the rrclientd release than
is documented here.
Procedure:
╖ Copy the distribution file rrclientd-1.3.tar.gz to your Linux PC.
╖ Login as root for all of the following :-
╖ Expand the distribution (with gunzip) & then untar it.
╖ In directory rrclientd-1.3/bin you will find all the executables
that you need: fetchmail (not used) kdestroy kinit rdate rrclientd
rrdhcpcd rrpasswd
╖ Rename /sbin/dhcpcd to /sbin/dhcpcd.orig. Copy & rename rrdhcpcd
to /sbin/dhcpcd
╖ Copy kdestroy,kinit,rdate,rrclientd,rrdhcpd,rrpasswd to
/usr/local/bin
╖ Set up your ethernet card to use dhcp & restart the system. If the
dhcp configuration is ok - an IP address will be assigned - with
the details being places in /etc/dhcpc/hostinfo-eth0 &
/etc/dhcpc/resolv.conf
You may see a startup warning about not finding dhcp.conf - this
doesn't seem to matter.
** At this point you should be able to ping proxy-server
successfully.
(If you can't then you won't be able to login later)
╖ Copy the krb5.ini file (from your Win95 \netmanag directory) to
/etc/krb5.conf
You will need to make the following changes (adding 2 new sections)
The example shown is for the Melbourne krb5.ini file - Sydney users
will need to substitute appropriately.
This is also documented in the distribution's examples/ sub-
directories.

╖ Save your existing services file /etc/services to

Copy the services file from examples/Nassau/services to
/etc/services
╖ Create a new file /etc/rrpasswd - with the contents being your
current BPC password
╖ Change the PATH environment variable as follows
PATH=$PATH:/usr/local/bin ; export PATH (This is most likely not
necessary)
╖ Login to BPC as follows
rrclientd -u <username> /etc/rrpasswd dce-server
so if you're username jsmith
rrclientd -u jsmith /etc/rrpasswd dce-server
If this is successful you'll see a message in /var/log/messages
indicating it was ok.
tail /var/log/messages will display the end of the file.
╖ Logout of BPC by entering rrclientd -k
╖ To make this automatic - you'll need to set the PATH & invoke
rrclientd each time the system boots.
╖ The rrpasswd command has NOT been tried.
╖ That's it - setup your Linux Netscape proxies & go for it !!
╖ According to the documentation the client will logout & then login
automatically at 3am. This has not been checked.
Problems
If you don't setup the PATH properly - then the login will fail with
GSS_API complaints about non-supported checksum type.
If you don't make the needed changes to krb5.conf you'll also get a
similar error.
If you are using your PC to dual/triple boot between W95/NT/Linux -
the PC's CMOS clock will be altered by Linux - giving continual
Kerberos errors if you try & login using NT. You need to login using
Win95 first (which will fix the CMOS clock settings), then you can get
in via NT.
Make sure you setup you PC time/timezone correctly in Linux. Note also
that the /var/log/messages timestamps are a bit strange :) (possibly
referenced to GMT)
3.11. Fibertel, Buenos Aires, Argentina
This information is provided by Pablo Godel
My name is Pablo Godel and want report that I'm using the cable
service of Fibertel in Buenos Aires, Argentina and it works perfectly
with Linux.
They gave me a static IP. The brand of the cablemodem is COM21 and the
model is ComPort.
I connect it to the nic properly, configured in Linux and it worked
perfectly.
More information about Fibertel can be found at
http://www.fibertel.com.ar
3.12. Videotron (Videon), Canada
I don't have much information about Videotron except the fact that
they use DHCP for the assignment of IP addresses and other networking
information. Just read the DHCP mini-HOWTO
(http://metalab.unc.edu/LDP/HOWTO/mini/DHCP.html) and configure your
system appropriately. There is no other necessary configuration. Also
important thing to note is that the Ethernet card that Videotron
distributes is a NE2000 compatible PCI card for which you need to use
ne2k-pci driver
Additional information from Philip Gwyn (gwynp@artware.qc.ca):
They use Motorola CyberSURFR (sic) modems. This will give you an
ethernet NIC when you sign up. They gave me a TMC NE2000 PCI clone,
which Linux recognises as a "RealTek RTL-8029". It couldn't configure
it propperly however, until I downloaded the manufacturer's driver
disk and changed the media type to "auto-config".
While they can't guarantee to get it working with Linux, they will do
a bit of hand holding so it works. Many of the tech-support have
Linux-clues, as it were, even asking questions like "what kernel are
you running?" "do you have the latest version of dhcpcd?". When
their DHCP server broke, they even suggested I delete the cache files
in /etc/dhcpcd to start over from zero, as it were. This worked.
Additional information from Mihai Petre (mihaip@videotron.ca):
Yes they are using DHCP for the tcp settings. They have also included
dhcpcd on their ftp server at (ftp://ftp.videotron.ca/pub/linux/). You
can also try posting your problems on news.powersurfr.com newsgroup
videon.linux.
Their only limitation regarding making a server is a 1 Gig upload
limit and a 6 Gig download limit.
Information about Videotron can be found at http://www.videotron.ca
3.13. Telekabel (Teleweb), Austria
According to Andreas Kostyrka:
╖ You may want to mention, that the Austrian Telekabel (Teleweb) ISP
works with Linux. It seems quite similiar like MediaOne Express
(3c509+dhcp, etc.)
╖ Second there are 3COM configuration utilities for Linux (But don't
fool around with them on a busy system, 3c509 may lock the bus if
touched the wrong way :( ):
ftp://ftp.redhat.com/pub/contrib/hurricane/SRPMS/3c5x9utils-1.0-3.src.rpm
ftp://ftp.redhat.com/pub/contrib/readmes/3c5x9utils-1.0-1.README
Information about Telekabel can be found at http://www.telekabel.at/
3.14. Tebecai, Netherlands
According to Frodo Looijaard:
Tebecai is yet another provider which uses a LANcity cable modem
connected to a 10BaseT ethernet card. DHCP is used for configuration
(see the DHCP mini-HOWTO at
http://metalab.unc.edu/LDP/HOWTO/mini/DHCP.html). A step-by-step
guide to install the cable modem under Linux can be found at
http://huizen.dds.nl/~frodol/
(in dutch), but it is really very straightforward. You must only
remember that your IP-address is not visible from the Internet (it is
on the private 10.x.y.z subnet), so you can not setup a publicly
available server.
Information about Tebecai can be found at http://www.tebenet.nl (in
dutch only).
3.15. A2000, Netherlands
This information is provided by Johan List J.A.List@speed.A2000.nl:
Basically the way to go is the same as with Tebecai. A2000 provides
cable internet access by means of a LANCity cable modem, connected to
an 10BaseT ethernet card. This also works well for the
"Vortex/Boomerang" cards by 3COM (I've got a 3COM Boomerang Fast
Etherlink XL 10/100Mb TX Ethernet Adapter), providing you compile the
Vortex/Boomerang drivers. (See the Linux Ethernet-HOWTO)
Setting up access can be done with DHCP (See the DHCP-Mini-HOWTO). A
Dutch guide to setting up Internet access for A2000 is available at
http://agvk.a2000.nl/LINUX/index.html.
Contrary to Tebecai, your IP-number *is* visible from the Internet, so
take your precautions regarding security and safety when setting up a
Linux machine using A2000 Internet access!!
3.16. Shaw Cable, Canada
According to Peng F. Mok pmok@shaw.wave.ca:
I recently signed up for a cable modem service from Shaw Cable here in
Canada, which they have christened `Shaw Wave'. They also appear to
have another service called `Shaw@Home' which they are using in some
locations. Shaw has been upgrading their cable network for about a
year and a half now, and now offer cable-modem service to a number of
locations across Canada. Information about the `Shaw Wave' service
can be found at http://www.shaw.wave.ca while information about the
`Shaw@Home' service can be found at http://shaw.home.com General
information about Shaw Cable can be found at http://www.shaw.ca
I thought I'd just drop you a line to inform you that your DHCP mini-
HOWTO, (http://metalab.unc.edu/LDP/HOWTO/mini/DHCP.html) was very
useful in helping me set up Linux to work with my cable-modem service,
and that you might want to add `Shaw Wave' (and perhaps `Shaw@Home')
to your Cable-Modem mini-HOWTO as another entry explaining how to set
up Linux with the service. I don't have specific information on the
`Shaw@Home' service yet, but from conversations I've had with Shaw
technical support it seems that `Shaw@Home' is a partnership with
```@Home''' and involves the same features and setup procedure as that
already described for ```@Home''' in the Cable-Modem mini-HOWTO
document.
In both services Shaw Cable techs will come over and bring you two
pieces of hardware -- a Motorola CyberSURFR cable-modem and either a
3Com EtherLink III 16-Bit ISA 3C509B-TPO NIC or an EtherLink XL PCI
3C900-TPO NIC. You have your choice of either an ISA or a PCI card
depending on your needs, and these models only have the RJ-45 (UTP)
connectors. The ISA cards come with PnP-mode enabled by default, so
it may be necessary to boot into DOS, disable PnP operation, and
configure the card to some base I/O address and IRQ setting which are
available. Once this is done Linux should have no problems detecting
the NIC at boot-time. I'm not sure about what needs to be done in the
case of a PCI card since I don't currently have a PC which supports
either PCI or PnP.
Note from another user:
Shaw now also issues SMC PCI ethernet cards. They give these out
without boxes or manuals. I found out that these are the SMC
EtherPower PCI RJ45 card (model 8432T). They use the DEC 21041 chip
so the tulip ethernet driver is needed for it.
If you need to set up your POP3 mailboxes you can do that at following
URL:

and you can login and setup the POP3 mailboxes that way.
Oh, and for the record, Shaw's technical support is horrendous. The
best place to go for information is the athome.users-unix newsgroup
(which is not even mentioned by any of the documentation) or please

3.17. Cogeco Cable, Canada
This information is provided thanks to Terry O'Grady
togrady@cgocable.net
I have a Cable Modem through a company called Cogeco Cable located in
various parts of Canada. They are part of the "Wave" system which
includes Rogers Cable and Shaw Cable. The technical setup is different
for each provider though. They supplied me with a D-Link ethernet card
(the version of that has changed since then but I believe are still
using D-Link) and a Zenith modem. The Ip setup is easy since they use
DHCP so all I did was install the dhcp daemon
(http://metalab.unc.edu/LDP/HOWTO/mini/DHCP.html) and that was that.
If you like you can list my e-mail address togrady@cgocable.net for
anyone with questions.

Optimum Online uses DHCP, and rrclientd in Linux, by John Clark.
Check out http://www.netaxis.com/~wharris/optimum/index.html for
instructions on how to set up your service with Linux.
Tell people who had private ips who have public ips now to change
their /etc/resolv.conf to look like this... domain nassau.cv.net (or
optonline.net depenind on the users mood) nameserver 167.206.112.3
nameserver 167.206.112.4 Other Than that its the same setup procedure
note: the rrclientd software will work if you tell it dce-server and
you specify the domain as optonline.net
3.19. Singapore Cable Vision, Singapore
This information is provided by Jieyao (jieyao@letterbox.com):
SCV provides Motorola Cybersurfer modem connected to the network card
via UTP cable. The IP setup is easy since they use DHCP so all you
need to do is install the dhcp daemon
(http://metalab.unc.edu/LDP/HOWTO/mini/DHCP.html). If you can't make
access the first time, turn the modem off then on again.
3.20. Cable Wanadoo, France
This information is provided by Jerome SAUTRET
(Jerome.Sautret@wanadoo.fr):
I just read your Cable Modem HOWTO. I live in France, and I use Cable
Wanadoo, the cable service of France Telecom, which is the main
telecom operator in France. It is available in a few cities in France
at the moment, like Angers and Metz. This service provides a dynamic
IP address via DHCP. It uses a COM 21 modem plugged in a 10BaseT
Ethernet card. The IP setup is easy just read the DHCP mini HOWTO
(http://metalab.unc.edu/LDP/HOWTO/mini/DHCP.html).
3.21. Prime Cable Expressnet, Las Vegas, NV
This information is provided by jedi jedi@penguin.lcvm.com:
They use the Com21 which can either be connected directly to your
10baseT input or inserted into the downlink input on your router.
Static IPs are available for $10 per month and the usual address
assignment is through DHCP (
http://metalab.unc.edu/LDP/HOWTO/mini/DHCP.html )

every 10 min, 1 user only (theorically ... ), no problem with
firewall, the web server on my computer is even reachable from
outside..., full speed FROM internet, small speed TO internet.
╖ No so cheap : for small office use, same as 1) but not limited to 1
user and more speed TO internet.
╖ Expensive : for WWW servers & ... , Static IP addresses and
reserved bandwidth TO internet following price.
Speed :
>From TVD's mirror site : up to 250Kbytes/sec, very nice ( and YES,
they have some Linux mirrors like redhat ... :-) ) >From internet :
variable but rather good if the remote server isn't overloaded.

3.23. Telenet Vlaanderen, Belgium
This information provided by Karel Goderis (karel.goderis@pandora.be):
Operator: Telenet Vlaanderen - Operational in flemish speaking
(northern) part of Belgium
Hardware: Motorola CyberSURFR Wave Cable Modem using an RJ-45
Ethernet crosscable to a PC
Software: Standard config is Windoze + Modified Netscape for newbie
installations, although Linux i386 support is there under the form of
mirrored redhat.com software on the internal ftp servers
IP Setup: DHCP address assignment
(http://metalab.unc.edu/LDP/HOWTO/mini/DHCP.html) , single address
only. Outgoing : all ports accepted, except mandatory use of Netscape
Proxy on port 8080, and thus port 80 blocked. Incoming : ports 0-1024
blocked, but re-allocation of ports on Linux works fine.
Pricing: one-off installation : BF 10000 (+-$ 250) + BF 3000 ($75)
deposit for the cable modem (+$25 for Ethernet NIC if not present in
pc) monthly rental : BF 1500 ($40)
Services: redhat.com netscape.com mirrors, quake I and II servers,
proxy, mail relay and pop account (4 aliases) and the other usual
stuff you need to survive on the net.
Caveats: Telenet states that you can download 300Mbytes/month, but
this rule is not enforced unless there is a obvious abuse (i.e. you
download 300Mbytes/*day* ;-) )

3.24. Total-Web, United States
This information is provided by iota (iota@inaxx.net):
I work for Convergence.com, a cable internet company who provides the
network monitoring, technical support, and advice to cable providers
(who, in turn, provide the internet service to their customers). Most
of our markets are through Cablevision, one of the more popular cable
providers in the eastern US. The service name that they operate their
cable internet service under is "Total-Web". Customers are provided
with a static IP; simply set this up like you would any other ethernet
device under Linux. The modems we use are LanCity LCP's and COM21
ComPort's, but these devices should be transparent to your computer.
Total-Web is available in limited areas, including: Miami Beach, FL;
Gwinnett County and Roswell, GA; Cookeville, Lebanon, and Columbia,
TN; and many other test markets.
3.25. CyberCable, Paris, France
This information is provided by David Monniaux:
CyberCable gives you an ethernet card if you need one. It is a cheap
NE2000 clone, ISA-Pnp or PCI I think. They only know how to set up the
stuff for Windows, but reports from other people say that they let you
use their access with other systems, provided you do the software
setup yourself.
They use DHCP (http://metalab.unc.edu/LDP/HOWTO/mini/DHCP.html).
DHCPcd in RedHat worked immediately. In RedHat's netcfg, this means
selecting "DHCP configuration". There are still some problems
sometimes: DHCP outputs some error messages, but things still work
afterwards generally (?). This seems related to rebooting; it looks
like the cable system doesn't reallocate the line for one minute after
reboot.
CyberCable's web site is at http://www.cybercable.fr.
3.26. StjΣrnTV, Stockholm Sweden
This information is provided by Fredrik Staxaeng (
fstx@algorithmica.se ) :
StjΣrnTV sells a Bay Networks Versalar Cable Modem 100, and they
include a NetGear ethernet card in the initial fee. Just set your
interface to DHCP (http://metalab.unc.edu/LDP/HOWTO/mini/DHCP.html).
Info about their service is available at http://www.starport.se
4. Hybrid Cable modem ISPs
If you think you have the card recognized you have to now look at the
entry for your ISP. I have sorted the information according to a
provider because setups are mostly ISP specific.
This section is for people who are using so-called "hybrid" cable
modems. Hybrid modems are modems that need two hookups (connections),
one to the (TV) cable and one to the phone line. TV cable is used for
downloading while phone line is used for uploading.

4.2. LinkExpress, Brasil
This information is provided by Rodrigo Severo (rodrigo@who.net):
First of all, let me tell you that here we have the MMD Cable Modem
from General Instrument. We use SurfBoard 1000 ISA board for download
and a regular telephone modem for upload. I would prefer to use an
external board like the SurfBoard 1200 which is available only to
corporate users, i.e., willing to pay US$ 200,00 instead of the
regular US$ 30,00 so I found out this driver for the internal ISA
board. For home users, Linkexpress (my ISP) just installs and
supports the internal ISA board - Surfboard 1000. If you want to use
it, you have to install Windows 95/98 on your computer and let the guy
from Linkexpress install the equipment. After that, make your Linux
installation as you like.
I started from the files I downloaded from
http://home.adelphia.net/~siglercm/.
Here is the relevant data:
______________________________________________________________________
ISP: LinkExpress <http://www.linkexpress.com.br>
DNS: 200.252.88.20
Frequency: 351 MHz
Phone number: 321 3300
City: Brasilia
Province: Distrito Federal
Upload speed: regular 33.6K (just the download goes through the
cable modem)
______________________________________________________________________
During a download from a local tucows mirror I got 70KB 300KB per
second. From distant sites I managed to get 30KB/s a few times.

4.3. ExpressNet, Maryland
I recently accuired an expressnet cable modem for the maryland area.
it is a com21 one way modem and I had a hell a time making it work so
id like to share my knowledge in your faq maybe? well heres what I
learned inorder for the PPP connection to authenticate the user must
be running PAP which consists of editing the /etc/ppp/pap-secrets file
accordingly
______________________________________________________________________
#/etc/ppp/pap-secrets
#this is the PAP secrets file for PPP
#the quotes are required on both
"username" * "password"
______________________________________________________________________
after that they must create a PPP-on script what ever name it must
execute this command
______________________________________________________________________
exec /usr/sbin/pppd debug persist /dev/ttyS1 38400 0.0.0.0:0.0.0.0 connect "chat -v TIMEOUT 3 ABORT 'BUSY' ABORT 'NOANSWER' '' ATH TIMEOUT 30 'OK' ATDTTELEPHONE CONNECT ''"
______________________________________________________________________
this must be done with no carrage returns either
next step is to modify the /etc/ppp/ip-up.local file if it does not
exist it should be created it should read the following
______________________________________________________________________
#!/bin/bash
#/etc/ppp/ip-up.local
#this will set up the route to the ppp device as default everytime the modem
#authenticates dont include it if you do not want this option
route add default ppp0
______________________________________________________________________
then the user must configure their ethernet card on box I have a 3c905
I configured it the following way
______________________________________________________________________
ifconfig eth0 up
ifconfig eth0 10.0.0.1 broadcast 10.0.0.15 netmask 255.255.255.240
______________________________________________________________________
then I added some more routes to the kernel routing table as follows
______________________________________________________________________
route add -host 10.0.0.1 eth0
route add -net 10.0.0.0 eth0
______________________________________________________________________
all of these commands can be added into a script file as follows
______________________________________________________________________
#!/bin/bash
#This is a script file for establishing the cable modem IF device properties as
#well as the route properties
ifconfig eth0 up
ifconfig eth0 10.0.0.1 broadcast 10.0.0.15 netmask 255.255.255.240
route add -host 10.0.0.1 eth0
route add -net 10.0.0.0 eth0
______________________________________________________________________
thats all and the cable modem connection is setup fast as hell I might
add.

4.4. Charter Pipeline, Riverside, CA
This information is provided by Gabriel Peters (gpx1@earthlink.net):
(I have Charter Pipeline, Powered by Earthlink, Riverside, CA) The
modem is a Com21 ComPORT 2000.. connected to the computer via 10 BaseT
ethernet cable to a Linksys 10/100 ethernet card (Cable modem,
ethernet cabling, and ethernet card supplied) The ethernet card driver
that I had to compile into the kernel was for the DEC Tulip. auto-
detected the card and set it up nicely.
This is the information I needed:
______________________________________________________________________
eth0 IP address - 10.0.0.1
DNS Servers - 207.217.126.81, 207.217.120.83
Subnet Mask - 255.255.255.240
Gateway: None
Your hostname should be CBL-(your username).hs.earthlink.net
______________________________________________________________________
Then you need to configure PPP to dial up your access number as
normal.. What I had to do to get it to work was this: I typed
'ifconfig eth0 down' to shutdown the ethernet, ppp-go to dial in, once
it reported my IP addresses, i typed 'ifconfig eth0 up' and voila, it
worked perfectly.
Editor's comment:
Each time PPP link is brought up or down pppd executes scripts
/etc/ppp/ip-up (link up) and /etc/ppp/ip-down (link down) so in order
to have Ethernet network go up and down with PPP link simply add
ifconfig eth0 up
before 'exit 0' statement in /etc/ppp/ip-up and ifconfig eth0 down in
ip-down.
4.5. Chambers Cable, Chico, CA / Fundy Cable, New Brunswick
This information is provided by Brian Moore (bem@cmc.net):
For those using Chambers Cable in Chico, CA, the product is the
Scientific Atlanta data Xcellerator(tm) modem. Mike Cumings of Cal
State University wrote a nifty driver for it, available at
http://www.ecst.csuchico.edu/~mcumings/cablemodem/. This should also
work for others using the same modem, such as Fundy Cable of New
Brunswick.
