TCU supports Linux connectivity to the internet for QuickNet
The support for Linux at QuickNet will be a growing as Linux become more
and more popular. Currently, RedHat is supported.
We plan to support other Linux versions (like CalderaLite, Slackware, SUSE)
in the future.
Currently, you may contact The Computer Underground at 485-0506. If
staff are not available at the current time, please contact QuickNet. Mark
Nielsen, the president of TCU, will be available at late nights and on
weekends if other staff from TCU are not available. Mark may also be reached
at email@example.com and he answers his e-mail daily.
In extreme situations where these instructions don't work, you may bring
your computer into TCU and we will setup your computer for free to get
it connected to QuickNet's services. NOTE: You must be using RedHat 5.0
or higher and you must have an internal ISA non Plug-And-Pray modem or
an external non WinTel modem. Please setup an appointment with Mark if
you need assistance.
Setting up ppp for RedHat Linux
Only ISA non Plug-And-Pray modems are supported with Linux. A 56k non-WinTel
modem will work. If you have questions about which type of modem you should
buy, please contact The Computer UnderGround
and we will provide you with an internal 56k modem for around $60 or an
external modem for around $100.
After you have started your Linux computer as "root", start xwindows
by logging into the console and then by entering "startx" at the prompt.
A control panel should appear on your left hand side. If your control panel
does not appear, then your xwindows session may not be working right, you
haven't logged in as "root", or someone changed your xwindows settings.
Choosing your modem
The first option to choose in the control-panel is "Modem Configuration".
There is a button that looks like a modem and if you leave your mouse over
the button, it should display the title of the button. Next, click on the
button to bring up the "Modem Configuration" menu. Choose the com port
your modem is conencted to and then press "Ok". If you wanted to do it
manually, you could do this -- FOR EXPERTS ONLY:
# For com1
ln -s /dev/cua0 /dev/modem
# For com2
ln -s /dev/cua1 /dev/modem
Setting up PPP using the ppp0 device in your control-panel
Here are the steps I did to get ppp setup. I did this as root and
I will later explain how to use ppp as a normal user.
To activate and deactivate the modem as root, again, in the control-panel,
choose "Network Configurations", then choose "Interfaces", select "ppp0",
then click on "Activate" or "Deactivate" or turn the modem off and on.
The control panel should be there, choose network configuration.
In this program, choose "Interfaces".
Click on "Add".
Enter in the phone number, username, and password.
Click on "Use pap authentication".
Click on "done".
Click on "save".
- Now we need to set your DNS up correctly. Click on "Names" in the top
menu of the Network Configurator. You should see "Nameservers" there.
- Enter "127.0.0.1" as one of the entries unless you have the number
which should have been given to you by your ISP. 127.0.0.1 is a bad choice
and should only be used as a last resource. Also, if you enter 127.0.0.1,
you must have your DNS server installed locally and running in order for
it to work. For QuickNet users, enter "10.10.10.10" and also
"10.10.10.11". These two numbers only work for people who dial in.
- For QuickNet users, also enter "qn.net" in the "Domain" entry.
- Click on "Save".
- Click on "Interfaces" in the top menu.
Now click on "Activate" for the ppp option you just made.
Letting non-root users use the modem
Now if you want to let users activate and deactivate it,
Now a normal user can activate and deactivate network devices with usernetctl
or usernet. I recommend usernetctl. For the device ppp0, here are the commands
assuming you used the steps above...
In your contro-panel, choose "Network Configurations", then choose "Interfaces",
and highlight your ppp entry which is usuallly named "ppp0".
Click on edit.
Click on "Allow any user ..."
Click on done, click on save, click on save again.
There is also a product called Diald which will connect your computer to
the internet if someone tries to get to the internet. This product is beyond
the free support for Linux for QuickNet. If you wish for TCU to setup your
computer using Diald, you may bring it in, we will charge $25. Please contact
the president of TCU for further
information. You may want to also try to figure out diald yourself by looking
at this DIALD
usernetctl ppp0 up
usernetctl ppp0 down
My experiences with PPP in RedHat has been very good. Anytime there
is no connection, it redials. This includes busy signals and when it gets
disconnected. You have to wait about 10 seconds before it redials.
Other sources for ppp, slip, and roadrunner
I plan to have more info about how to setup stuff for ppp later.

ppp, slip, and others including an up and down script.
