| − | To mount a disk image on [[FreeBSD]]:
| + | == Definition == |
| | | | |
| − | First attach the image to unit #1:
| + | In Computer Forensics '''slack''' refers to the bytes after the logical end of a file and the end of the cluster wherein the final byte of the valid file resides. |
| − | # mdconfig -a -t vnode -f /big3/project/images/img/67.img -u 1
| + | |
| | | | |
| − | Then mount:
| + | == Slack Types == |
| − | # mount -t msdos /dev/md1s1 /mnt
| + | |
| | | | |
| − | # ls /mnt
| + | === RAM Slack === |
| − | BOOTLOG.PRV BOOTLOG.TXT COMMAND.COM IO.SYS MSDOS.SYS
| + | |
| | | | |
| − | To unmount:
| + | === File Slack === |
| | | | |
| − | # umount /mnt
| + | == External Links == |
| − | # mdconfig -d -u 1
| + | |
| − | | + | |
| − | To mount the image read-only, use:
| + | |
| − | | + | |
| − | # mdconfig -o readonly -a -t vnode -f /big3/project/images/img/67.img -u 1
| + | |
| − | # mount -o ro -t msdos /dev/md1s1 /mnt

| − | ==To mount a disk image on [[Linux]]== | + | |
| − | | + | |
| − | # mount -t vfat -o loop,ro,noexec img.dd /mnt
| + | |
| − | | + | |
| − | The '''''ro''''' is for read-only.
| + | |
| − | | + | |
| − | This will mount NSRL ISOs:
| + | |
| − | | + | |
| − | # mount /home/simsong/RDS_218_A.iso /mnt/nsrl -t iso9660 -o loop,ro,noexec
| + | |

| − | Some raw images contains multiple partitions (e.g. full HD image). In this case, it's necessary to specify a starting offset for each partition.
| + | |
| − | | + | |
| − | # mount -t vfat -o loop,offset=32256,ro,noexec img.dd /mnt/tmp_1
| + | |
| − | # mount -t vfat -o loop,offset=20974464000,ro,noexec img.dd /mnt/tmp_2

| − | | + | |
| − | Mounting raw images with multiple partitions is easy with ''kpartx''. Type ''aptitude install kpartx'' as root to install ''kpartx'' unter Debian. ''kpartx'' is creating device-mappings for each partition. If the raw image looks like this:
| + | |
| − | | + | |
| − | Device Boot Start End Blocks Id System
| + | |
| − | rawimage.dd1 1 1 8001 83 Linux
| + | |
| − | rawimage.dd2 2 2 8032+ 5 Extended
| + | |
| − | rawimage.dd5 2 2 8001 83 Linux
| + | |
| − | | + | |
| − | creates the command
| + | |
| − | | + | |
| − | # kpartx -v -a rawimage.dd
| + | |
| − | | + | |
| − | this mappings
| + | |
| − | | + | |
| − | /dev/mapper/loop0p1
| + | |
| − | /dev/mapper/loop0p2
| + | |
| − | /dev/mapper/loop0p5
| + | |
| − | | + | |
| − | The Partitions can now mount easy with
| + | |
| − | | + | |
| − | # mount /dev/mapper/loop0p1 /media/suspectHD_01/ -o ro
| + | |
| − | # mount /dev/mapper/loop0p5 /media/suspectHD_02/ -o ro
| + | |
| − | | + | |
| − | Don't forget the switch '''''-o ro''''' !
| + | |
| − | | + | |
| − | ==To unmount==
| + | |
| − | | + | |
| − | # umount /mnt
