How to get llama 2 up and running , in a VM, with no GPU, and limited memory on Ubuntu

Image
OK I decided to write this up after unsuccessfully being able to find all the required info I needed in one place. In this setup we will be using Ubuntu Server 22.04.2 LTS as the OS. I have this running on a home lab ESXi server 8, on a HP Compaq Pro 6300 SFF CPU = Intel Core i7-3770 Installed Memory 16 GB I have some 10K SAS drives installed for the VM's If you have not already, navigate to  Get Ubuntu Server | Download | Ubuntu and download the 22.04.2 LTS ISO Next Lets create our VM that we are going to run this in. *Note Im using ESXi however you can probably do this in Workstation, Fusion, VirtualBox etc The main things to note on the VM creation. Set Ubuntu 64 bit as the guest OS Set your CPU relevant to the physicals CPU, I will be starting with 4 VCPU Set your Memory to as much as you can tolerate, I will be using 12 Disk Space - we are creating a 100G swap file, and the rest of the file can take up some room , so more is better if you can afford it Dont forget to add the U

Horizon View 2-factor Authentication for Free! with Google Authenticator or others

So after quite a bit of work on my proof of concept google authenticator server, a colleague pointed out that LinOPT has already created this, along a whole slew of other options. So after spending a couple of nights reading and testing I figured id post a simple walk-through to get this up and running in your environment. As mentioned in the title this is a Free solution , however if you are wanting to scale this in a large organization you would most likely want to explore their support contracts , this is a good fall back when things just don't work and this also help the developers keep this type of software free for the rest of us. To start off we want to create 2 objects in Active Director. The first is just a standard user account LinOTP will use to connect to your domain. You can put these any where in your domain as we will access them directly later. In my case i create one called 'LinOTP Svc' and put it in the default Users OU. Next create a Global or

Update 10/2017:  Since starting this project  I was informed that such a thing already existed , so I will not be moving forward with this. You can use LinOTP in your enterprise environment. As a continuation of my previous post I wanted to see if I could build a simple server to to allow users to generate google authentication keys, and authenticate to Horizon View.  After some research I was finally able to get a 'functional' server up and running and easily deplorable. No going forward please realize as I said before this is a PROOF OF CONCEPT, you should not deploy this in your production environment, you have been warned (See notes at the end of this page), however if you want something to mess around with to build your own , here ya go. To being your going to need an ubuntu server, see my original posts Part1 and Part2 to get a working Ubuntu server in your environment.(make the username gauth as it will make ruining the config scripts easier) Once your have

Recovery of data off a Netgear Ready Nas NV+ SPARC edition

Ran into an issue where the NIC got fried on my Readynas , I had backups of most of the data through USB but some data (expendable) was not backed up. However I still wanted to recover this data and found this post: http://home.bott.ca/webserver/?p=306 This actually worked with a few changes: First remove your drives from the ready nas 1 by 1, and mark on each one the number it is starting from left to right ( 1,2,3,4) Now place them in a PC and this is probably important , put them on each sata port in order, in my case my ports are 0,1,2,3. Download ubuntu 1604 LTS desktop IS for ease of use Down load Rufus to convert the ISO to a bootable USB https://rufus.akeo.ie/ make sure you computer has internet access boot the linux USB , choose try Ubuntu once booted to the desktop open up a terminal run the following: sudo su gedit /etc/apt/sources.list This will open up the graphical txt editor, Add the following line to the end of the file deb http://us.archive.ub

Access Point Gui 3.0.1 3.0.2 Ok so this is My last, last version of this as I am moving on to other projects. Last Updates include: config options for vIDM config options for system settings. removal of background image (it was causing long load times. some code cleanup. Also forgot to add a thumbprint box for vIDM Note about auto thumbprint for vidm, this will get the thumbprint from the server however it will not add the sha value at the beginning, this is due to a framework limitation, and i dont have the time figure out a new way, so if you auto generate your thumbprint, make sure to put a 'shat1:" or "sha256:" in front before submitting. Enjoy! Download Here

First make sure you have a DNS record for the server in active directory, as we are going to need it. This must be done first! Also create a AD security group named: GG_S_GOOGLE_AUTH_DISABLED Once done, go back to your console and run the following: sudo su enter your password apt-get update apt-get dist-upgrade say Y when prompted apt-get install ntp say Y when prompted apt-get install ntpdate should not prompt ntpdate pool.ntp.org Now we are going to install pbis-open for our connection to Active Directory wget -O - http://repo.pbis.beyondtrust.com/yum/RPM-GPG-KEY-pbis|sudo apt-key add -  wget -O /etc/apt/sources.list.d/pbiso.list http://repo.pbis.beyondtrust.com/apt/pbiso.list  apt-get update apt-get install pbis-open say Y when prompted Once that completes we can Join our Ubuntu server to the domain. domainjoin
