I've actually decided to go a completely different way. But this has actually created new problems. Instead of using any android products, I've decided to go with inexpensive mini computers. These come with 1 RJ45 Gigabyte port and 1 RJ45 2.5 Gigabyte Port. Thinking back to the cluster I helped...

Not looking to spend very much as this entire project is about repurposing discarded electronics. I have a roughly 10-year-old Toshiba laptop which I'll be using as a master node. For worker nodes, I've been slowly collecting old android phones. The master node will be directly connected via...

I am slowly collected a pile of old phones and tablets. I'd like to repurpose these devices into something that will help me make passive income mining cryptocurrency. (Monero) While this will start out as a farm, eventually I will "evolve" my collection of android devices into a Beowulf...

I started thinking about this pet project of mine about a year ago. You can't go anywhere these days without seeing something being mentioned about cyrpto currency. I had my first taste of potential when a small token coin shot from .0000001 to .02. Literally, overnight what was once worth...

Not sure where to ask questions on building clusters. I've been reading and researching quite a bit so far. Now I'm starting to gather the hardware I need to complete a pet clustering project. If you think about it, clusters can fit into networking and server as well. Perhaps a Cluster forum...

I should have done that from the start. I'm stuck on step #4. I've never been able to bring up the Kubernetes dashboard. Here's the link... https://ubuntu.com/tutorials/install-a-local-kubernetes-with-microk8s#1-overview Eventually, it will lead me to doing this...

I'm not sure how the router would actually come into play. From what I'm understanding so far, Kubernetes clusters are "virtual" but take advantage of nodes once they are installed. The "server" is the computer I've just installed Ubuntu onto. So I'm really not understanding why it can't see...

To the best of my knowledge, there is no firewall in place. At least at a router level, as I'm using the stock cable company's provided router. Would a firewall prevent me from seeing the randomly generated Kubernetes cluster and port from the computer the server is located on? Question... I...

I'm following along with an online tutorial to install Kubernetes on Ubuntu. This is part of a larger how-to mine cryptocurrency (Monero) on a Kubernetes cluster using XMRig. I got as far as step 4 on Canonical's website attempting to run the command "kubectl get all --all-namespaces". Every...

I'm attempting to build a small cryptocurrency mining Beowulf cluster on a shoestring budget. The server is my 10yr old Toshiba laptop. Nodes will be android phones running Ubuntu. Most of my questions will be regarding the wireless aspect of this cluster. Ideally, I know it would be best for...

I wrote that comment in haste now that I've had time to think about it. As I had mentioned in my original post, this book was written 20 years ago. Just how current will the information in it be? From a basic concept point of view, some things will not have changed, but how it's done more than...

After a 20+ year recess from Linux, I'm going back and re-teaching myself. While looking for resources I came across a pre-owned copy of O'Reilly Press "Building Linux Clusters" written by David HM Spector. I was unaware when I ordered it that the CD which should have been included, wasn't in...

Expirion, I appreciate the link you posted. I regret however mention the cluster aspect of my pet project. I need refresh basic Linux along with bash scripting. Although I watched a 4 part series on YouTube setting up a cluster which covered installing ssh, making a shared file for all nodes to...

I have to apologize! In my zeal to complete this pet project of mine, I jumped the gun in my question last week. The last time I had hands-on time with any flavor of Linux was way back in 2001 when Redhat and Mandrake were all the rage. I would assume in the many years that have since passed...

It’s been over 20 years since I worked with Linux. I have a project that I’m interested in building a Beowulf HA cluster using Ubuntu. There are so many online classes via Coursera and Udemy, I don’t know which would be best to brush on my skills. Suggestions?
