Fail to start KPPP and network

satimis · 05-09-2005, 06:41 AM

Hi folks,

Fedora Core 3

After playing around to setup KPPP following functions failed to response

Remark:
Login as "USER" either on KDE destop OR on Gnome desktop

KStart -> Internet -> KPPP
KStart -> System Settings -> Network
both failed to start allowing me to keyin password

I must login as "root" to start
KStart -> Internet -> KPPP
KStart -> System Settings -> Network

Kindly advise where can I rectify these problems

TIA

B.R.

What is your modem?

Hi fancypiper,

Tks for your links

External modem. The modem and its cable have no problem. I tested them on a FC2 box which also has an external modem of same model. I exchanged them. Both modems worked on FC2 without problem.

I was trying to solve the problem of unable to dial ISP and came to this dead knot. Before I can start KPPP as USER on KDE desktop

KStart -> Internet -> KPPP
popup for password. After keying password, KPPP login screen started. I can query modem but failed to dail. I tried more than 3 days without a solution.

Now even
KStart -> System Settings -> Network
failed to popup request for password

There are 2 types of external, usb, which can be winmodems and require drivers, others are serial port modems.

External Modems

Serial port connect to (Windows com 1) /dev/ttyS0 and (Windows com 2) /dev/ttyS1. The symbolic link /dev/modem should point to which port it is attached to.

You should have a program called wvdial installed, I think.

su - to become root and try this command:

wvdialconf /etc/wvdial.conf

Is the modem found and configured? Examine the file /etc/wvdial.conf and put the information for your isp in that file and save. Then the command, as root,

wvdial

should connect you if your /etc/resolv.conf has the proper nameserver numbers in it.

Hi fancypiper,

Tks for your advice and URLs

This is not my first time to setup KPPP. I did it several times before but never coming to this deadknot.

The external modem is connected to Com1. This PC has another mobile HD running M$WinXP. I just tested the modem on M$WinXP. It worked without problem, dialing and connected to ISP finally.

On Fedora Core 3
KPPP started, modem initialized but failing to dial. The login screen was just hanging there without dialing and finally closed automatically.

They are IP address of broadband.

I tried stoping the broadband and comment out both of the them. But situation remained unchagned unable to dail. The lights of modem were blinking. ISP phone number, login and password rechecked and found correct.

In your /etc/wvdial.conf, remove the semicolon and put the correct username, password and telephone number needed for your ISP account

The semicolons in /etc/wvdial.conf may be your problem.

Once that is corrected and the correct dial up numbers for your ISPs nameservers are in /etc/resolv.conf, then the command wvdial as root should connect.

Make a symbolic link to point to /dev/ttyS0

ln -s /dev/ttyS0 /dev/modem

Then the redhat-config-network utility in the Gnome gui should set it up so the user can bring dialup up and down.

At least you can now connect through a root x terminal.

The networking commands may not be installed (you can pick and choose with the expert install, sometimes the default doesn't install things I expect to have) and there may have been some initial bugs in the install, so I suggest that you now:

Check the Fedora site and see if there is an erratta or change in their networking stuff (I still use core 1).

Check out the Fedora Core 3 Tips and Tricks and make sure you are fully updated and how they now do their network stuff. FC1 had an "internet connection wizard" in something called "start here" with the nautilus file manager.

1. Configure your software managers and some simple commands will update, install software with dependency resolution, etc. Personally, I like a combination of up2date and yum the best as they seem to have more stuff available and they just out performe the apt-get.

Good luck and now enjoy some new and awesome power.
