Resize Disk in for VM images (Kali Linux as a Guest OS)

1. In VMware settings, change the disk size

2. Boot the VM image with the installation Disk ISO. You can choose the startup device in the VMware settings. 

3. Open the GParted application. 

4. Since the added space is at the end, you need to delete the swap Linux patitaion first, then you can expand your /dev/sda1. 

Details see: http://askubuntu.com/questions/51272/how-do-i-repartition-with-gparted

1. In the machine's settings point the CD Drive to the .iso file with your Ubuntu LiveCD. You may also need to make sure the "Connect at power on" check box is checked.
2. Power the virtual machine on and hit F2 with the focus inside the machine.
3. Once inside the BIOS move to the Boot tab and select CD-Rom as primary boot device.
4. Run gParted - I think it's always there.
5. Destroy the swap partition: swapoff, delete the extended and linux-swap partitions.
6. Resize your primary partition to desired size.
7. Allocate your swap back again to whatever you like - create an extended partition and then allocate as linux swap. Remember about swapon :)

And that's it. You now have a big primary partition!

In my case you'd need to have Jedi reflexes to get into BIOS by pressing F2 on the splash screen - the boot delay is just too short. What you can do to slow it down is go to your vm's .vmx file and type in something reasonable like:

Setup FTP server

CentOS

# yum install vsftpd ftp -y

FTP login uses plain/clear text, you can use SFTP to encrypt the login

If you have following problem when use FTP to login:

Name (localhost:dbadmin): username

Password:
500 OOPS: cannot change directory:/home/username
Login failed.

You just need to disable selinux and reboot

To disable permanently, I edited /etc/selinux/config and set

SELINUX=disabled

After the reboot, I was able to log in normally.
