Connecting to the Internet on ubuntu
Hi everyone, I am a new user of ubuntu with a little knowledge of netwrking and modems. I have encountered some problems trying to set up a (56kb) dial up connection and I am getting into trouble. I would appreciate if anyone can help me online and step by step to set it up! Thanks in advance for your help!

(a) get your access data (user, password, number to dial)
(b) install pppconfig (that's the name in Debian, should be the same in ubuntu)
(c) run pppconfig and answer the questions correctly.
That should do the trick.

I had installed it but it just doesn't run! I reinstalled it but it didn't help!What can I do now?
What do you mean by "doesn't run"? What's the console output?
PS
Ubuntu isn't Windows, you know. Neither re-installing, nor rebooting, nor format c: is required to make things work...

Sorry! I just had trouble running it because I wasn't root! It may seem a bit unusual but now that I have finished the configuration, what should I do?

Try
> pppd call your-isp-here
and, if there is no error:
> ping 66.249.93.104
If you get a reply, you are online. If not, you
(a) didn't set up the dial-in data right
(b) your modem doesn't work in linux (winmodem)
(c) your modem would work, but isn't configured properly
(d) your ISP is having trouble

when I wanted to ping, I got this error:
connect: Network is unreachable.
c) I haven't configured the modem, how should I do it?
a) Maybe it is because of the ppp configuration, I had some questions about it
1) what is the difference between choosing static for configuring nameservers or dynamic?
2) What is the difference between PAP, chat and CHAP in authentication method?
3) Can the port speed you choose cause such a problem?
I know my questions may seem a bit unusual but I have had no previous experience of doing such a thing!

Oh, I somehow assumed you modem would be working already. Google for your modem's name and 'linux', and perhaps 'howto'. You might also have a look at
http://linmodems.org/
to figure out if it can be used with linux at all and, if yes, how. (If it is a built-in Laptop modem, use
> lspci
to figure out the modems name/chipset.
1) what is the difference between choosing static for configuring nameservers or dynamic?
- If you know a nameserver that will accept name resolution requests from any client, you can use that. Otherwise, you have to use the 'dynamic' config. You ISP then submits (automatically) the servers it uses.
2) What is the difference between PAP, chat and CHAP in authentication method?
- PAP is the "Password Authentication Protocol", CHAP the "Challange Handshake Authentication Protocol". With PAP, the client basically sends the password (either plain or encryted), while with CHAP the server sends a challange which is signed by the host. The signature is then verified by the server (the Server->Client->Server route of the challange-packet(s) is called "Handshake"). So CHAP is more secure, however, not supported by any ISP I've ever dealt with...
3) Can the port speed you choose cause such a problem?
- Yes, you have to choose the right speed, which is most likely the highest you can choose (I'm not sure if any auto-detection in cause of failure is implemented there).

I used the scanModem and the chipset found was the following:
silicon labratories Intel 537[winmodem]
I found that it works on linux on the site below:
http://rzr.online.fr/docs/comp/modem.htm
It had some other information but I didn't understand many parts of it! I haven't found anything else yet and I am still in trouble! Anyway, thanks a lot for your explanation! It really helped me since I was confused about these parts in pppconfig!
