There is no random host or domain on your computer. After install, in Slackware, your hostname will be "darkstar" unless you changed it to something else during the network configuration.
My box's hostname is "rick" my domain name is miles.home. On our home network I am
rick@miles.home. My daughters box's hostname is "leila" her address on the network is
leila@miles.home.
In netconfig you should not create a domain name that ends in things like .com, .net, .org, .com.au, etc.
Forget about your ISP's linux setup instructions for now.
I don't really understand what you have or have not done so let's start from scratch and work this through methodically.
If you don't have a home network (I do), all you want netconfig for is to set up loopback. By memory I think you can leave everything else blank.
Next try doing everything else using kppp. It's the easiest way to set up a dialup connection if your modem is set up and you can talk to it, but kppp must be set upfor each user. If you set it up for testing in root, you will still have to set it up for yourself as a user.
Follow through what I've written below and come back after you have and you can tel us something worked or you can provide some usefull info why it didn't and/or error messages.
(1) start kppp
(2) click "Setup.."
(3) When KPPP Configuration opens up first click "Modem" tab.
(4) Next click the "Query Modem" button and if you see "Modem Ready" you know
you have a modem interface.
(5) If you don't have a modem interface Click the "Device" tab and check and see
if you have the correct device selected. I Use a winmodem which is set up a bit
differently to an external modem. My modem device is /dev/modem which points to
/dev/ttyLT0. Here's the output of ls -l /dev/modem on my box
lrwxrwxrwx 1 root root 11 Oct 12 15:25 /dev/modem ->
/dev/ttyLT0
Other settings are Hardware: [CRTSCTS], Line Termination: CR, and Connection
speed: 230400.
(6) Next click the accounts tab.
(7) If you are set up correctly you should see your ISP's domain in the box, My
ISP is "optusnet.com.au" the (www is omitted). If You don't see your ISP
correctly entered, omit what there and proceed by pressing the "New" button. If
it is there and correct press the "Edit" button.
(8) OK, first in Edi Account window is "Dial" I have Connection name: optusnet
(name yours what you like this is for your use), my ISP's dialup telephone
number is in the center box, My Authentication is PAP/CHAP. You must have these
correct for your ISP.
(9) Click the "IP" tab. I have my Dynamic IP address ticked. That was default I
did not change this because my IP adddress is assigned by my ISP when I
connect.
(10) Click the "Gateway" tab. I have "Default Gateway" and "Assign the default
route to......" ticked.
(11) Click the "DNS" tab. I only have my ISP's domain name "optusnet.com.au"
enteredhere and the "Automatic" radio button ticked. Again remember that you
don'tpreceed your ISP's domain name withh www ( or
http://).
(12) That's all you need click "OK"
(13) Don't worry about "Graph" or "Misc.) when you return to KPPP Configuration.
Just click "OK" and return to the kppp dialup interface.
(14) Enter your Login ID, Password and make sure that "Show log window" is
ticked.
(15) Try to dial out. The log window should open up and tell you what is
happening. Note this down it may be usefull. If you fail to connect you will get
a popup window telling you why and you will have an option to write the error
message to a file in your "username" directory. Do it.
