OpenSSL How To Renew A Certificate

[@leibaleibovich5806]

Greetings, David! Thank you very much for all detailed tutorials that you are producing! These are much better than average ~10 min videos out there. My apologies for a somewhat off-topic comment, but I would really appreciate if you could stir me in the right direction. **Here is the basic setup**: I have a laptop with Linux installed on it. The machine is decent, but fairly old and unfit for a serious computational work. Lets say, I would like to buy a "mini-PC" and install Linux on it (it could also be Jetson Nano!). Granted, the "mini-PC" is not exactly a supercomputer, but it will have more modern CPU, more hard-drive storage and could be left to run by itself for long periods of time, while I am using the laptop for other tasks. Here are limitations: (a) I do not have space for a proper monitor to attach my "mini-PC" to; (b) I do not have a router either (or a home network for that matter); (c) last, but not least, I am a novice and fairly inexperienced with IT technology and networking (which is my main concern). To be clear, (a) and (b) are simply limitations of an place that I rent. I am wondering if I can connect the laptop and the "mini-PC" by an Ethernet cable and create a "network" of two machines. Essentially, I would use my laptop as a keyboard and a screen to connect to the "mini-PC", do some work on it, launch some tasks, disconnect. Hopefully, my description is not too confusing! I am wondering what type of cable do I need (e.g. crossover cable?) and what type of software I need to install for this improvised "remoting"? Are there any alternatives to abovementioned approach? I am rather inexperienced, so any guidance will be appreciated!

You seem to have a good idea already of what needs doing You can connect the computers together using a crossover cable They should randomly pick IP addresses but it would be better to statically configure these e.g. 192.168.10.10 and 192.168.10.11 with a subnet mask of 255.255.255.0. There is no gateway necessary when there's just two computers involved If you want remote CLI access to a Linux computer then SSH is the way to go. Depending on the distro it may need the OpenSSH server installing If you want desktop access to a Linux computer then you can use VNC. RealVNC is a commercial offering while x11vnc and vino are some of the free basic options and I think Ubuntu might have vino installed by default Remmina is a common client you can use on Linux and I use it for RDP, SSH and VNC connections although it does support others

@@TechTutorialsDavidMcKone Greetings! Thank you very much for replying to my comment! Much appreciated. In your reply there is definitely new information for me to study! Actually, I have been wondering for a long time whether I could "amalgamate" an old laptop and a "mini-PC" or a single board computer. Few years ago I thought about Jetson Nano (a developer kit), when it was priced at $99 or so. Then Jetsons disappeared, but I managed to get a jetson-based reComputer. However, even though I got the cheapest reComputer, I had to pay roughly $300 for it. It might sound silly, but I am less willing to experiment with it with no experience -- would be a pity to damage it. Interestingly, when I tried to investigate possible setup with Jetson, I was recommended to use a Micro-USB cable (instead of a network cable). Now it occurs to me that I should have procured myself a RaspberryPi. It would have been less costly, if I had destroyed it. However, now even Raspberries are in short supply and their price tripled! I am wondering whether I should still consider getting a cheap SBC to test my non-existing networking skills!
