Adding read support for the NTFS file system is a rather non-trivial step on a Fedora 8 system. You basically have two choices:
Build your own custom kernel and enable NTFS file system support. This means you'll constantly need to build your entire kernel on your development system each time Fedora 8 releases a new version with security patches.
Download the appropriate RPM from http://linux-ntfs.sourceforge.net/ for your kernel and install it.
We typically use option two as it is less time consuming. If you feel particularily lucky, you can use the bin/ntfs_fetch_install script to download a good guess at the appropriate RPM for your system. At the time of this writing, this script only downloads the RPM and tells you what you need to do to actually install it (Paul was hesitant to automate the installation of any modules into the active kernel on your development system).
Once installed, your Network Security Toolkit will then be capable of mounting NTFS file systems in read only mode. This can be particularily handy in the recovery of files from Windows machines which are in trouble.
