first, login as root.
next, launch terminal and type this:
uname -r
note the kernel version of your Fedora Core 3.
next, go to:
NTFS rpms and download the appropriate rpm package for installing the ntfs kernel.
next, in terminal type this command from the folder in which the downloaded rpm is there:
rpm -ivh ****.rpm
to install the ntfs kernel.
note: replace ****.rpm with the exact name of the rpm package.
next, load the kernel by typing:
/sbin/modprobe ntfs
create a folder
ntfsdrive in /mnt
mount your ntfs partition by typing:
mount /dev/hda1 /mnt/ntfsdrive -t ntfs -r -o umask=0222
also, go to the folder /etc
edit
fstab file and add this line:
/dev/hda1 /mnt/ntfsdrive ntfs ro,umask=0222 0 0
in all this, I assume that hda1 is the partition that you want to mount.
from now on, linux will automatically mount the hda1 partition for you when it loads.
next, you haven't told whether you have internal or external modem.
for external modem:
firstly, launch Terminal and type setup. from there select the System Services option and ensure that the "kudzu" service is enabled. reboot if necessary.
you should know whether the modem is plugged into COM 1 port or COM 2 port.
next, in Gnome,
go to System Settings --> Network and there select the "Hardware" tab.
next click on Edit tab.
here, the modem device should either be /dev/ttyS0 (for COM1) or /dev/ttyS1 (for COM2)
next make the "baud rate" = 115200
and the "Flow Control" should be Hardware (CRTSCTS)
now, create an internet connection, fill-up it's phone number, username, password etc
and then try connecting to internet.
you're in hard luck if you have internal modem, you'll need to download the drivers for internal modem, as most of the internal modems are winModems and they aren't detected by linux.
for internal modems, read GNUrag's post on finding drivers for internal modems.
