Tasker can help you create tasks which basically run curl commands, and can be set up as buttons on the phone launcher.
So I assume you have a web server somewhere which is configured to host virtual hosts in some regard. You need to set up a virtual host which is configured to respond to requests for mydomain.com and reply with a redirect to aa.mydomain.com. The DNS for the domain root must be an A record, so you will have to set the IP address for your web server on the A record for mydomain.com. How exactly this looks and what sticky points you have in setting this up depends on what your web server setup is like - maybe you have this all working, but if not, if this is just an apache or nginx install, then we need to work through setting up the virtual host, or if this is a docker style nginx letsencrypt manager, then thats another set of configuration issues.
Let me know how far you've gotten, or if nowhere at all and you need a recommendation for how to do this, let me know. Let me know a little more about your web server environment that responds to mydomain.com if you have one set up (linux? windows? router with pfsense?)
The way I do this is my router forwards all http and https traffic to my web server running ubuntu, and docker-letsencrypt-nginx-proxy-companion handles all the virtual hosts. Then if I wanted to create a redirect for a single domain, I would make a docker container that served an nginx server and have it configured with a redirect. But I must acknowledge I've been a sysadmin for 10 years and there may be more user friendly turnkey ways to do this, I'm just doing what works for me.
This is just a WordPress quirk, you did everything ok. You can usually solve this but using wp-cli to do a global find and replace for your IP address with the new domain name on your WordPress install. Another option is setting some constants which are something like SITE_HOME (I'm not sure that's right) in your wp-co fig.php file. Google "change domain WordPress" and it should point you in the right direction.
If you have a central server which is performing backups, and the client computer trusts the server, use syncthing to mirror the files on the client to the server. Syncthing also has an android client.
If the client computer doesn't trust the server, for example you are offering a backup destination for friends or extended family, then use duplicati for incremental encrypted backups.
Both options work on both linux and windows.
Nah, even if it didnt have throughput issues it would be far more effort than necessary to set up.
My recomendation, get a used Linksys WRT1200AC and put openwrt on it. It's basically as if they put a raspberry pi 3 into a linksys router, it has much more processing and memory than most cheap routers and you can get it used for about $50.
Ubuntu server, some bash scripts, and a docker install. KISS
Last I tried this, the Nvidia cli I stalker was easy peasy for my 1050ti.
However, I haven't took a look at jellyfin, but the Intel quicksync encoder on the Intel chip on my home server did the same encoding tasks and was far less temperamental with plex than Nvidia was. Do you really need the GPU? If it's just for video encoding I feel like you could skip it. If it's for more esoteric stuff like running LLM then of course it's a requirement.
Used Dell Optiplex SFF (Small Form Factor) PC from ebay. They are tiny and total powerhouses for home server stuff. I run one with a 1 TB SSD and 16 TB hard disk, and it runs basically all of that using docker containers. And minus the storage it cost me about $120 bucks.
There is this thing called the internet, it's filled with web servers. It's what cybersecurity is basically all about.
A web server is more than just a thing that serves up personal web pages. Virtually all system to system communication uses a web servers nowadays, the world runs on APIs.
I feel like this is like asking why you'd have to know how a stove works if you're going to be a cook. It's more than just related, it's practically the core most fundamental thing you need to know how it works in order to be a cybersecurity pentest person.
Imho attitude's like this really turn me off in some people. A friend of mine wanted to learn computer programming and information technology, so I gave him a crash course on docker with the goal of setting up a container to handle vpn bittorrent downloads. Really simple stuff, like copy and pasting a few commands. He asked why even do this if he can just use deluge on his desktop. Like, it's missing the forest for the trees, you need to know how stuff works to be useful to people that are looking to hire people who know how stuff works.
The friend of mine was hoping to work with me as a contractor so he could get high paid computer work, but frankly, I don't need to hire someone who is too lazy to learn even the most basic fundamentals. And in your case, knowing how a web server works is fundamentals. And you can figure out the basics in only a few days.
The only way you're going to make it in info tech is to be curious and figure out how stuff works. That is the *only* real skill you need to succeed.
I wrote a bunch of scripts that for each file I got from bittorrent, it removes it from the daily backups, and instead has a log of what file goes where and what torrent it came from. I've actually had to use it's restore function a few times because I'm trigger happy and sometimes ruin my server. One of these days I will clean up the script and make it portable...
Oh dude, yeah ChatGPT knows Linux and docker better than I do and I've been doing this sort of thing professionally for 15 years, lol. Whatever you need as far as writing scripts, invoking containers, or generally asking it questions, you can just consider it an expert network administrator and it can write all your scripts and whathaveyou.
One of the best moments this year was when I realized I never had to figure out how to write an iptables command again lol
I'm in the exact same situation, and I've been eyeing the device on amazon named: "Mediasonic PROBOX 4 Bay 3.5” SATA Hard Drive Enclosure – USB 3.0 eSATA Support (HF2-SU3S3)" - I think this is what you are looking for. If I understand correctly, a single eSata cable will be able to drive all 4 drives in this box, so basically as much expandability as you want.
