I have some questions about Linux, related to an older question I posted
I knew that the only way to have read/write access to NTFS partitions from a Linux OS is to manually install some NTFS drivers and I was told that this is not suggested, because such drivers are not very stable. It has been a while since the last time I used Linux. I installed the new version of Ubuntu yesterday and I found out that I could read and write data to an NTFS partition as soon as I installed the OS, without making any other configuration!!!
The fact that this functionality is supported by default... does it mean that it was properly testet, and I don't have to worry about damaging the data on my windows partition when I write on it from Linux ? How can I found out what drivers are actually used in Linux to access the NTFS filesystems ?
I also want a good application for making image files of disk partitions (for backup). I want to be able to create an image file of the OS partition, store that image on another partition, and then being able to boot from a cd (in case the partition is destroyed and cannot load the OS) to restore the partition from the image file. In windows I'm using Norton Ghost and I was told that I can use Ghost for Linux Partitions too. Is there a different version of Ghost for Linux ? I tried to make an image of the Linux Partition from Windows but it seems this is not possible.
Finally, Is there any built-in firewall in Ubuntu ? If yes, how can I configure it ? Or is there any good third-party firewall which I can use in Linux ?
