The way to your solution
Have you ever upgraded the ESXi software on HPE Servers and after reboot iLO did not come up anymore? Well, this is what happened to me after installation of ESXi software patches on a couple of HPE servers. Even the ESXi patches were installed successfully and the ESXi hypervisor started correctly, the iLO interface couldn’t be reached anymore. All the installation was done remotely, so there was no physical access
This will be the first post out of series of posts about creating a smart home system with Raspberry Pi, different kind of sensors and the powerful visual tool for wiring sensor data – Node-RED. Node-RED is a flow-based development tool for visual programming for wiring together hardware devices, APIs and online services in new and interesting ways. It provides a browser-based editor which can be used to wire together
In today’s post, I would like to show you the process of transforming a single NIC old laptop into an OPNsense firewall/router. I wanted for some time to install pfSense in my home network, but I didn’t want to buy an expensive already made firewall device. After spending a few days looking for a solution, I found at some point that Dell PowerEdge R210 II is quite used as hardware
Why I need to do this?! Because I’ve made a backup of a RPi’s SD Card to a Linux VM and now I would like to restore the created image file back to the SD Card. For the moment I’m doing this only to see how should be made, my RPi still works very good, but is always good to be prepared in case something goes wrong. Before starting the
I think Raspbbery Pi is a great device and I love how easy and fun is to create IoT projects using it. I am using Raspberry Pi at my vacation house and also at my parents summer house. It is monitoring remotely the temperature, the voltage of batteries connected to the wind-turbine and solar-panels and controlling the alarm system and some relays that are starting and stopping different appliances. These
A SSH key is an access credential in the SSH Protocol. SSH keys offer a more secure way of logging into a server with SSH than using user and password. More over, using a SSH-Key gives you the possibility to automate the login process, meaning you could create a script that will login to another computer without user intervention. More info about SSH-Keys could be find here. Let’s see how
There are cases when a remote computer could be hard to reach. This computer could be placed behind a firewall or a router (NAT) whose rules or settings cannot be changed. An easy and practical solution that could help us in this case is to set up a reverse SSH tunnel on Linux. Reverse SSH tunneling allows you to create a connection from the remote computer to a local computer
