Nobody wants my info dump. I know way too much about networking and computers. The topics are massively deep, like iceberg levels of deep. One for each topic.

I could lecture for an entire day on the nuance and considerations of picking a Wi-Fi channel, or you can ignore me and just hit "auto" which may or may not take some, or all, of my considerations into account when selecting a channel.

If anyone is keen to hear some generally good advice about home networking, here's my elevator speech:

Wire when you can, wireless when you have to. Wi-Fi is shared and half duplex, every wired connection is exclusive to the device and full duplex. If you can't Ethernet, use MoCA, or powerline (depending on what internal power structures you have, this can be excellent or unusable, keep your receipts). Mesh is best with a dedicated backhaul, better with a wired backhaul. Demand it from any system you consider. The latest and greatest Wi-Fi technology probably won't fix whatever problem you're having, it will only temporarily reduce the symptoms and you won't notice it for a while. Be weary about upgrading and ask yourself why you require the upgrade. Newer wireless won't fix bad signal, or dropouts.

For everything else, Google. That's how I find most of the information I know.

Good luck.

I'll be around in case anyone has questions. No promises on when I'll be able to reply tho.

5 or 6Ghz backhaul on the mesh?

Should I buy consumer or small business hardware?

Recommended brand(s)?

[–] MystikIncarnate@lemmy.ca 28 points 1 week ago* (last edited 1 week ago) (2 children)

High end consumer aka prosumer, which is only really one brand, ubiquiti. Specifically their unifi stuff.

Or used mid range business stuff, Cisco, Aruba, juniper. The pinch here is that you usually need specialized knowledge to configure this class of device. I've also used Cisco, watchguard, Fortinet, Sophos, sonicwall, and probably others for firewalls. I prefer Sonicwall for some very specific reasons about how they structure their configuration, but for anyone who isn't a certified sonicwall tech, I'd point at Sophos. Their stuff seems to be a fair balance of configurability and user friendliness. If you're instant on new business stuff and you have the money for it, Sophos for the firewall, Aruba instanton for switching and Wi-Fi.

The benefit to unifi is user friendliness and a unified control console. If you're not an IT professional or a similar technical job, unifi will provide plenty of what you need and leave out the unnecessary knobs that needs like me want to see.

Be prepared to spend several hundred on the networking if you're going to do it right, there are some places you can trim some costs, but before you nope it from sticker shock, consider how much you spend per year on Internet service, and then consider how much the router/firewall + switch + access points are in comparison... And those are things you don't need to buy every year.

Edit: I forgot to mention the backhaul. The decision will depend on the wireless environment. You might be able to save some cash having 5ghz backhaul, but it's going to struggle in dense environments, so consider spending some extra on 6ghz if you're in a medium to high density housing situation. Good luck

Tell Me everything you want about MAC addresses

[–] MystikIncarnate@lemmy.ca 28 points 1 week ago (11 children)

Is this a kink?

The first six hexadecimal digits of the Mac address are referred to as the oui, or organizationally unique identifier. They are supposed to all be registered, but with modern systems, mac address randomization is common, so the Mac address in use can be little better than nonsense.

I have a theory that some of the more budget oriented manufacturers (think Ali express), just don't bother using a registered mac address at all.

This all makes my job harder as a network admin, I usually need to look up what a device is by mac address to help identify what it is and what it's doing. I need to make sure everything is on the right network, and I can't do that if I don't know what anything is.

The last six hexadecimal digits of the Mac are simply to uniquely identify the interface that the Mac is burned into. This also means that any systems with multiple network ports, have different mac address on each port. Some things are exempt, like network switches, but for the most part, every interface has, or is supposed to have, a unique mac address.

Also, the mac isn't hex, it's binary. Hex is just how we've decided to present it to users. The switches, routers, and interfaces don't work with the hex, only the binary. Same for IP addresses, which normal are shown in "dotted decimal notation", but are just binary. But you didn't ask about IP.

Did you need me to whisper ouis into your ear and you can guess what company is registered to that oui?

Thanks a lot for sharing you experience! I recently saw some people I follow on youtube talk about fibre as an alternative for ethernet cables, do you have an any experience with that?

[–] LurkingLuddite@piefed.social 18 points 1 week ago (1 children)

Alternative? Sure. Though why?

If ethernet works, you're just using a more expensive option to go with fiber.

Unless you need something unique about fiber, like distance (which can still be dubious for consumer grade hardware), or a non-electrical based signal (dubious requirement in most cases), then you're just throwing money at being able to say you use fiber.

[–] RustyNova@lemmy.world 14 points 1 week ago (2 children)

Additionally, fiber is more fragile than a copper cable. One bad hit with a vacuum cleaner and it's toast

Actually makes me wish I had kids, this is brilliant.

I've been getting a lot of spam calls lately. Eventually said fuck it and screwed with them as much as possible. The best times were where I had something to do that didn't require much brainpower but had to be done. I eventually was able to keep them on the phone for up to a half an hour by pretending I was following their instructions until they realized I was bullshitting them. Everything from the internet being slow (and going on a rant about "ever since I moved to [made up town] I've had to deal with this shitty Internet, and they promised it to make it better X years ago") to fake accents and changing my voice, or sometimes just not having a clue if I have an iPhone or Android and getting walked through how to figure it out. Once they figure out I'm bullshitting them they get furious. Absolutely hilarious.

Unfortunately for the fuckery with the scammers I don't have as much brainless stuff to do at the moment. Though I still do fuck with them, I keep it short. Some things they really hate:

  • go into the bathroom, and when they're explaining their stuff flush the toilet so they can clearly hear it

  • answer in a voice like you're getting off. Instead of "yes" answer "Oh God yes". At a fitting moment say "Oh God I'm going to cum"

  • go really far away from the microphone and speak softly, and when they ask you to speak louder tell them you're already speaking loudly, something must be up with the line. They'll most likely turn up the volume. Once the conversation goes to their scam and they're not thinking about it anymore, scream as loud as you can into the microphone.

  • "How would you like to get fucked in the ass?" (Works best with men, considering those men often seem to be pretty prejudiced)

  • in a crazy voice: "HEY, WHAT DO YOU WANT, I'M TAKIN A SHIAAAAT"

  • "You say you're from [insert company they're pretending to be from]? Shit, your ex was right, you are a liar!

  • "you work for [insert company they're pretending to be from]? Is that what you tell your mother?

  • "Hey [insert their fake name they gave you, the way they pronounced it], if you're going to use a fake name, at least learn to pronounce it right"

  • if you recognize the name from an earlier call, reference what happened in that earlier call and rile them up further about it

  • when they're about to hang up: "don't be a chicken, don't hang up! I have a bet going with my friend here, if you hang up, I win!"

  • after getting insulted because you told them you know they're not who they say they are: "you're insulting me, which means I'm right, thank you!" [Proceed to laugh loudly]

Anyway, I have more, it's just not popping into my head at the moment. But creativity is the key here, and it's fucking entertaining.

Except now they record your voice and use it to train voice ai and scam you harder. My coworker's ex-husband got a call from their "daughter" distressed "kidnapped" needing money for ransom. Sent it and called the ex-wife. Daughter was sleeping at home.

Twice we got scammed. Well once for real, I caught the second one. I only realized the first one after my parents were already gone. My brother went on a solo psycho-journey when I was like 14, trans-Siberian railway through Russia and Mongolia, ended up in China. He was perhaps 19 at the time. A couple months in we got a call from China. Chinese embassy say my brother is in trouble. They read back his information, everything on the passport, is this him? Yes, it is. Keep in mind this was in the 90's when international calls to the other side of the planet cost actual money by the minute.

My parents spoke very broken English, and I was too young to speak properly to handle something like this, so there was a bunch of back and forth over several days, but it was clear to all of us that he was in trouble, and needed us to send money to get him out of whatever it was. China, ffs. I don't remember, shit I don't know even how much they ultimately sent, but it was likely by my estimates around $1500- a very solid chunk of change for our not necessarily struggling but not exactly thriving family either.

He came back a year later or so, and I don't know why but the whole debacle kind of never came up at the dinner table, until just like a year or so before my mom and dad both passed. We were all sitting after dinner, drinking and telling the usual family stories, and it came up, and we all laughed about how crazy that shit was to deal with back home when he was on his crazy first trip of his life and had to send money to China. He didn't laugh. He hadn't any clue what the fuck we were talking about, and nervously laughed it off.

At the time I just shook my head, of course he wouldn't remember when someone else bailed him out and saved his ass, narcissistic piece of shit as he is. Only after they passed did I realize, oh shit. There was no embassy, there was no emergency. Some entrepreneurial Chinese hostel manager just took down his info, somehow tracked down our parents (likely he had just straight up given them their contact information, just in case), and scammed us out of a decent amount of money.

My parents were hard working, we never wanted for anything, and they never let on we were actually not particularly well off and struggled at times. If they were alive, I still don't know if I would tell them. What was, was. What good is that heartbreak gonna do anybody thirty years after the fact? Anyway, that moment has passed either way, and well, we survived anyway, but damn it stings being the only one knowing this such a long time afterwards. My brother stayed a piece of shit and our remaining family have all gone no-contact with him, so even he doesn't know, it's just me.

The second time was possibly even more heart-breaking, but at least nobody lost any money. My parents, my father specifically, I mean both of them but this concerns my father- they grew up in a war torn country. My father had three brothers. He was youngest. When he was three years old, war broke out. The big one, number two, and in the worst possible place. He loved his brothers, and the eldest one got drafted, the story is unclear and lost to time, but joined the airforce somewhere abroad. The second one, I can't even recall, but he disappeared somewhere, sometime, somehow, and none of dad's family ever heard anything from him again- MIA, basically.

It was a big thing for my father, my grandmother too, she lived with us for years in the new country after the war, and just like in the story above, it's first after I got up in years and some that I realized what that haunted look was on her face as she zoned out and pulled her fingernails along the armseat of the leather chair that was hers, as the family watched TV together. Dad used to say, "Grama! Stop scritching!", it was a thing and we all laughed at it because grama scritched. She was thinking of her two lost sons- one of them went into the airforce but was also never heard from again, the other, who knows. Nothing good, probably. But they never knew.

Dad was like her, he just never got over it. He had kind of reconciled the fact that his eldest brother either died fighting, or after the war just relocated somewhere in another country and couldn't find his family back home again. But the other brother, it just itched him until the day he died, he used to light a candle every Christmas and make the table for one person extra, just so that in case he happened to come knocking, the table would be set for him to sit down and have Christmas dinner with us. We didn't think much of it, only, again, in my older years did I understand what emotional luggage was being brought out and put on display on that one night every year.

Sorry for being long-winded, but it kind of matters- decades go by, no more grama, parents getting old, and one day there is a letter. Dear so-and-so, it has come to our attention that a lost relative of yours, by the name so-and-so, has been trying to get in touch with you. Disclosed are his personal information, we are reaching out to you to make sure that you are actually related to this person, and would you want to accept his communication? If so, please get back to us by sending $100 to the following address for verification purposes, and he will be passed along your contact information.

My dad called me at work, "Something amazing has happened, get over here straight away after work". So, of course, I did. By then I was coming up on 40 working IT, I'd been around. I took one look at that letter and just laughed at it, "dad, this is a classic scam. Like, do you mind if I keep this? I have never seen an actual printed Nigerian Prince letter with stamps and all, like, they really went the extra mile with this one!", and he looked at me with despair, and I will never forgive myself for not being quicker on my feet and realizing the trauma I was casually laughing off, and said, "are you sure? His name is in there, and all, and our name is too, this is clearly real!".

He wanted so badly for it to be real, my mom sat by him, they both started arguing with me, like, clearly it was real, and that is when I knew for sure that it wasn't, because they weren't arguing with me, they were arguing with reality, or god himself, pleading for it to be real. I just shook my head, ever the bitter cold rationalist, "no, this is a very classic trick, and your long lost brother is not trying to contact you".

I don't know how I should have handled it, to me it was just another Nigerian scam letter, I was just overcome with the novelty of having a physical copy in my hand, but to my father, and to my mother, it was the one tiny spark of hope they had been waiting for, for decades.

That is the type of sorrow and grief that scammers prey on, and cause. Fuck them all to pieces.

I can only info dump when I'm prompted to start talking about something now. I have special interests, but I have no interest in talking about them with people that I can feel aren't really engaged. And the only people who ever engage eventually do get worn down after a while, or they're more knowledgeable than me about something and that makes me fall in infatuation with them.

So if anyone wants to talk about modding video games and get married, hmu. Modding specifically is my special interest, and the games I mod include:

Elder Scrolls series (primarily Oblivion/ Skyrim but I have played some modded morrowind within the last 5 years)

Fallout series (all of them! Ok, I haven't played 2 or the offshoots, but... shut up. New Vegas is my favorite :3)

Stardew Valley (I have 2700 hours in stardew :3 burnt out rn tho lowkey)

Dark Souls 1/3, Elden Ring

Baldurs Gate 3

Dragon Age (mostly origins, it continuously went downhill from there for me. I have done a couple modded replays of inquistion tho)

Minecraft

If you were to ask me what I could go on for the longest about? Probably New Vegas? Especially since I recently put in a fresh 200 hours. I finally got into TTW (a mod for new vegas that utilizes your copy of Fallout 3 goty to combine both games into a single experience) and installed it alongside some modernization modlists and HOLY SHIT.

I hadn't played since 2021, an era that seemed like New Vegas was dying. People had long moved onto Fallout 4, quest mods weren't coming out at the same frequency, etc

There was a total renaissance right after I left. If you haven't played new vegas in a while: consider coming back and finding a guide or using a program like wabbajack to mod your game.

I personally followed the Viva New Vegas guide, then after deciding to jump into TTW, I found that the VNV people have a guide for a TTW list called TBoT (The Best of Times). Both of these lists are,'in my experience, more stable than the base game. A lot of important performance and configuration mods came out.

Then, there's another list called WSG that I followed (wasteland survival guide), which added new content to the game and made it more hardcore.

If you made it this far and you really want to hear more, ask me a question. :3

When I was in graduate school, I used to call the 700 Club's prayer hotline and talk about my dissertation. To their credit, those people were remarkably patient and would only occasionally attempt to steer the conversation back in the direction of Jesus and his need to have some of my money. "Oh, I don't have any money. Anyway, it turns out that there's a perfect correlation between the giving of dowries and engagement in plow-based agriculture." Completely true but for some reason they didn't really care.

I am into old back-of-the-archive Korean historical dramas. They're lost? Even better. I've been scouring old newspapers for plots of old dramas (mostly dailies because they were the popular format in 70s SK) and plying them on an equally old forum dedicated to the topic. I've also been cataloguing them and trying to identify the oldest ones (TV guides between 1964 to 1970 didn't always list the name of the program, sometimes they'd just list it as "historical drama"). So far it seems I have the plots to most of the 70s historicals, which then opens new realizations that a lot of the more popular 80s shows are remakes of the 70s dramas. And those 80s dramas were then remade into 90s/2000s dramas and the occasional 2010s drama (there's been a major artistic shift starting from the Korean wave in 2003 that's stopped this cycle in TV dramas though). I can post the plots to a lot of these dramas and even started subtitling the ones that are more complete.

If you ask, I'll post a plotline here!

For people who think they're winning by fucking with scammers, unless you are tying up hours of their time, you are doing the opposite by engaging with them. And even if you tie up hours, they aren't really losing.

Obviously, falling for the scam is their ideal outcome, but ANY engagement beyond silence, a generic VM, or a disconnected/fax line marks your number as 'active' which can then be sold to other scammers.

So they still get a profit, and your number winds up on more scamming lists.

We are also getting close to the point where it won't even be an actual human you're talking to, it'll just be some AI, making engagement even more useless.

If you get a call from an unknown number and you don't have call screening, answer and SAY NOTHING! Not hello, not "may I ask whose calling", mute your phone so they don't even get background noise. The only numbers they can't get anything out of are the ones that are brick walls.
