Kali/Persistent USB

Start with your Kali USB drive. See Kali/Live USB for details.

Instructions

Following the instructions here: http://docs.kali.org/downloading/kali-linux-live-usb-persistence

In this example, we’ll create a new partition to store our persistent data into, starting right above the second Kali Live partition and ending at 7GB, put an ext3 file system onto it, and create a persistence.conf file on the new partition.

fdisk -l

Look for the USB drive. Should be at /dev/sdb.

Create Persistent Partition

Now we will create a partition on the USB drive, which will store persistent data.

Before

Here is what the disks look like before:

root@kali:~# fdisk -l

Disk /dev/sda: 232.9 GiB, 250059350016 bytes, 488397168 sectors
Units: sectors of 1 * 512 = 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Create Partition

Now we create the partition:

root@kali:~# end=7gb
root@kali:~# read start _ < <(du -bcm /root/mac/Users/charles/Downloads/torrent/kali-linux-2.0-amd64/kali-linux-2.0-amd64.iso | tail -1); echo $start; parted /dev/sdb mkpart primary $start $end
3167
Warning: You requested a partition from 3167MB to 7000MB (sectors
6185546..13671875).
The closest location we can manage is 3321MB to 7000MB (sectors
6485376..13671875).
Is this still acceptable to you?
Yes/No? y

Warning: The resulting partition is not properly aligned for best
performance.
Ignore/Cancel? Ignore

Information: You may need to update /etc/fstab.

After

Here is what the disks look like after. There is a new /dev/sdb3 partition:

root@kali:~# fdisk -l

Disk /dev/sda: 232.9 GiB, 250059350016 bytes, 488397168 sectors

Disk /dev/sdb: 14.5 GiB, 15512174592 bytes, 30297216 sectors
Units: sectors of 1 * 512 = 512 bytes

/dev/sdb3       6485376 13671875 7186500  3.4G 83 Linux

Disk /dev/loop0: 2.8 GiB, 2969686016 bytes, 5800168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

Make Filesystem

Now make a filesystem, and label it what you will (here, persistence):

mkfs.ext3 -L persistence /dev/sdb3
e2label /dev/sdb3 persistence

Mount Point

Last step is to create a mount point for the persistent partition. Then mount the partition, create a persistence config file in the partition, and unmount it.

root@kali:~# mkdir -p /mnt/usbdrive
root@kali:~# mount /dev/sdb3 /mnt/usbdrive
root@kali:~# echo "/ union" > /mnt/usbdrive/persistence.conf
root@kali:~# unmount /dev/sdb3
