% scp -pr /home alrac@filestore:rescuedfiles/-p preserves modification times, access times, and modes. This only makes sense on Linux file systems. -r means recursive, or copy all the contents of a directory.
If all you want to do is copy files from an NTFS partition, go ahead and mount the partition read-only:
% mkdir /mnt/ntfs % mount -t ntfs /dev/sda2 /mnt/ntfs -o roUsing your own device name, of course, which you can find with fdisk -l. ls /mnt/ntfs then displays your Windows files. Then you can copy the files to an existing Samba share. If you need to find your Samba shares, use smbtree:
% smbtree -N GROUP1 \\XENA anonymous file server \\XENA\HP_LaserJet_3050 HP_LaserJet_3050 \\XENA\IPC$ IPC Service (anonymous file server) \\XENA\common_share anonymous share for all users-N means don't ask for a password. If you need a password don't use -N. This example shows a single Samba server with a single file share, common_share, in the workgroup GROUP1, on host Xena. Next, mount this share on your SystemRescueCD computer, and mind your slashes:
% mkdir /mnt/commonshare % mount.cifs //xena/common_share /mnt/commonshare % cd /mnt/commonshareNow you can copy files back and forth with the cp command. If you have enough disk space on your Samba server you can grab the entire Documents and Settings folder, which holds the data files of all the local Windows users:
% cp -r /mnt/ntfs/Documents and Settings/ .The trailing dot is a shortcut for "current working directory". The easy way is to use tab-completion, so after typing "Doc" hit the tab key and it will auto-complete the file name. It will also enter backslashes, so it looks like this:
/mnt/ntfs/Documents\ and\ Settings/
If you want to edit some Windows files, then you need to use the NTFS-3G driver:
% ntfs-3g /dev/sda2 /mnt/ntfsThen you have several text editors to choose from: vim, Joe, nano, qemacs, and zile for the console, and Leafpad and Gvim for WindowMaker. It also includes a hex editor, hexedit.
First zero out the MBR, and preserve the partition table:
% dd if=/dev/zero of=/dev/hda bs=446 count=1The MBR is 512 bytes, and the first 446 contain the boot records. The remaining 66 bytes contain your partition table, so you don't want to erase that. (If you're thinking wow, this seems rather quaint and archaic, you are correct. The x86 architecture still thinks it's running MS-DOS. And that is why modern operating systems contain so many kludges just to boot successfully.)
It's usually not necessary to do this when Linux controls the MBR, but it doesn't hurt anything and it's good to know how to do it. If you want Windows to control the MBR, then you do need to zero it out before installing Windows, or before running any Windows boot fixit tools.
OK then, enough of that dull Windows stuff. Let's get back to nice sane Linux and open the GRUB command console:
% grub Probing devices to guess BIOS drives. This may take a long time. [snip boring stuff]Now find GRUB's stage1 loader:
grub> find /boot/grub/stage1 (hd0,3)If there is more than one, which there often is on a multiboot system, you need to know which one you want to use. (If you pick the wrong one, just boot SystemRescueCD and do it over.) Now enter the root partition:
grub> root (hd0,3) Filesystem type is ext2fs, partition type 0x83Then run GRUB's setup command:
grub> setup (hd0) Checking if "/boot/grub/stage1" exists...yes Checking if "/boot/grub/stage2" exists...yes Checking if "/boot/grub/e2fs_stage1_5" exists...yes Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 15 sectors are embedded. succeeded Running "install /boot/grub/stage1 (hd0) (hd0)1+15 p (hd0,3)/boot/grub/stage2 /boot/grub/menu.lst"...succeeded Done. grub> quitWhen you reboot you'll be welcomed by your familiar GRUB menu.
