Hi,
I have dual OP Windows XP and Fedora Core 5. I have Dial up internet in Windows and I want to use that internet while I'm using FC 5. I can mount the Windows Partition (hda1), but then how can I access to dial up internet? Can somebody help me?

It has nothing to do with mounting partitions, at least

You'll want to know how ppp (point-to-point protocol) works, or at least how the ppp client apps work: like kppp (for KDE), or some of it's quivalents on Gnome etc., or wvdial if you like using console or scripts.

With wvdial you'll run wvdialconf, a "program" that asks you your usernames etc., saves them in a file, maybe asks you to alter it if needed and then works by issuing wvdial on the console. Kppp, and similar apps are graphical and resemble the Windows' dialup window very closely: you have a settings button where you can add your information, and a connect button to start the connection. You most probably have some ppp app already installed if you're using Fedora. Check out kppp or read from Google..they're very easy/intuitive to use, but if you need help, just visit the web site of the app - but if you end up using a graphical application, I'll bet you know what to do if you've managed to get Windows on the net

Also make sure that you've an external modem since Linux support for winmodems is very thin

I know about winmodem, so I can takes care of that. Also, I know Kppp (for KDE), but when I use that I have to put my region phone number, it only asks for countries such as Bulgaria, Rome, Poland, etc. It does not have USA, so how can I put my dial up phone number. And I don't want to get charge for long distance. If anybody can help, please do so and I'll appreciate it.

In "kppp" the application asks what country to choose? YOU are correct. Using YOUR mouse keep clicking and YOU'll be able to establish a new account. Answer all the questions, please. YOU might need to scroll down and answer more questions. Depending on YOUR Display Settings. Keep scrolling and keep answering. As mentioned previously, use External Serial Modem. Reasons: A) Linux Kernels are configuring the Serial Port interface. B) The chip in the modem does the work, NOT YOUR Processor on the Motherboard. C) It takes time to configure PCI Internal Modems using Linux. It sometimes works. D) The Serial Port Connection is most reliable and has software to check current status in "text mode" or "GUI". Back within "Kppp", the application has two areas of special concern. A) Choose the correct Serial Port Connection. Try <ttyS0> , works for me most often. B) Check the modem status. This step is important,...the connection between YOUR system and the ISP utilizing this modem,..watching it perform is a pressure valve. It helps YOU focus on the items of interest that have a higher priority in YOUR scheme of things. If "NOT recognized", or "modem busy", choose another Serial Port Connection. They are listed in groups. The first four are the PCI locations. Towards the bottom are the laptop ports. Suggestion: If YOUR ISP gave YOU "mydogspot@rst.net" as YOUR "username", use the whole name. NOT "mydogspot" as "username". On the last tab of set up, choose the box and "x" it. The lock file notifies the software loop to continue. A big time-saver. For the time question, choose "60 seconds". Or if different, choose the maximum. That way YOU will connect more often, during peak hours of operation. Note: The Linux Kernel has the Serial Port Drivers in most Distro's. Before installing the Distro of YOUR choice, connect the Serial Cable. Make sure the power supply is installed, and the modem is turned on. Then install from CD-ROM. Change the BIOS to "First Boot Device" to be CD-ROM. Suggestion: While inside the BIOS, align the settings for YOUR software and hardware. NOT the bundle of settings that maximizes everything. YOUR system will run smoother.
