FreeBSD
To mount a disk image on FreeBSD:
First attach the image to unit #1:
# mdconfig -a -t vnode -f /big3/project/images/img/67.img -u 1
Then mount:
# mount -t msdos /dev/md1s1 /mnt
# ls /mnt BOOTLOG.PRV BOOTLOG.TXT COMMAND.COM IO.SYS MSDOS.SYS
To unmount:
# umount /mnt # 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
Linux
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
kpartx
Mounting raw images with multiple partitions is easy with kpartx. Type aptitude install kpartx as root to install kpartx under 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
The command
# kpartx -v -a rawimage.dd
creates these mappings
/dev/mapper/loop0p1 /dev/mapper/loop0p2 /dev/mapper/loop0p5
The partitions can be mounted with these commands:
# 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
