====== Controller install ======

Alito reinstalled using the VB repo: https://www.virtualbox.org/wiki/Linux_Downloads#Debian-basedLinuxdistributions

====== Creating a VM ======

Seemingly can only be done (or is easiest) through the GUI.

No need to install any desktop packages.

===== Networking =====

Select bridged mode for bidirectional access to the LAN.

Edit ''/etc/network/interfaces'' for a static IP:

    allow-hotplug eth0
    iface eth0 inet static
     address 10.0.0.14
     netmask 255.255.255.0
     gateway 10.0.0.2
     dns-domain local
     dns-nameservers 8.8.8.8

Then ''root@alito:/etc/network# ../init.d/networking restart'' (and get kicked off).

===== Samba for shared folders =====

==== Client/Guest ====

  apt-get install cifs-utils

Create ''/etc/samba/credentials'' chmod 400 as root containing

  username=samba_user
  password=samba_password

and add to fstab

  //10.0.0.1/slack  /alan  cifs  credentials=/etc/samba/credentials  0 0

  cd /home
  mv slack slack.old
  ln -s /alan/alito slack

==== Server/Host ====

To reenable symlinks despite the [[https://odzangba.wordpress.com/2011/01/02/fix-samba-not-following-symlinks-error/|security implications]], edit /etc/samba/smb.conf

  follow symlinks = yes
  wide links = yes

And add the user if you're not using an existing one

  smbpasswd -a slack

===== Guest Additions (for shared folders) -- DON'T DO THIS, IT'S JUST A TOY =====

No longer downloaded as an .iso, download, open with VirtualBox and they are added to the controller.  They can be installed to a specific machine firstly by inserting the imaginary iso in the imaginary drive (Devices --> Insert ISO into drive...) and then by running the executable in '/media/cdrom0' as root.

If you get

    root@alito:/media/cdrom0# ./VBoxLinuxAdditions.run
    bash: ./VBoxLinuxAdditions.run: Permission denied

It's probably a [[http://blog.ackx.net/virtualbox-guest-additions-common-errors.html|fstab problem]].  In /etc/fstab, change this:

    /dev/sr0        /media/cdrom0   udf,iso9660 user,noauto     0       0

To this:

    /dev/sr0        /media/cdrom0   udf,iso9660 user,exec     0       0

and remount.  You will also need to install "gcc, make, the header files for your Linux kernel and possibly perl".

    apt-get install gcc make linux-headers-$(uname -r) perl

Then sort permissions

  adduser vboxsf slack

and log out and in again.  Rm /home/slack and ln it to ''/media/sf_whatever''.

===== NFS -- DON'T DO THIS, NFS AND DEBIAN HAVE BECOME A COMPLETE SHITSHOW =====

Install ''nfs-common nfs-kernel-server portmap''.

==== Server ====

Config in ''/etc/exports''

  /home/slack/alito  10.0.0.14(rw,subtree_check)

Restart with ''root@alan:/etc# init.d/nfs-kernel-server reload''

==== Client ====

Config in ''/etc/fstab''

  alan:/home/slack/alito  /home/slack  nfs  rw,user,auto  0  0
