I for one really appreciate the effort of supporting non-AT drives despite the initial skepticism.

Network Engineering@infosec.pub•How does a computer create a 'Response' packet?English
1·2 years agoI believe so, yes. The routing table should result in the PC sending the response via the direct route, as opposed to via the defGW. I’m not 100% sure, though. There could be some “default” behavior of using the same nic as the one the packet was received on, stemming from the original 192.168.2.0/24 destination.

1·2 years agoFirst. It uses the source IP to craft the response, then does a lookup in its routing table to figure out on which interface is used for transmission. If necessary it will do an ARP request to figure out the MAC as well.

0·2 years agoI’m leaning towards “no”. His fragile ego will have taken two nasty blows in a row. Plus in four years he’ll be even older and more fragile, and it’s already pretty bad.
If I’m right, I’m sure he’ll endorse some other maga-clown instead.
I really love that band. It truly defines the Syntax Error genre.
I honestly don’t remember my printer brand. And that’s a good sign. I bought it years ago, and it now lives under my basement stairs on a static IP via wifi, accepting the on average bimonthly print job that I need from it. Then I walk down, fetch the print, and close the door on it again. I should name it Harry Potter.

Ask Lemmy@lemmy.world•What's your juicy work drama that you just want to tell us about?
1·3 years agoThat one of the key people who knows how our technology works, how to improve it, and how much of a failure the current “upgrade” really is (engineering forced this “upgrade” without talking to those of us who know) will be handing in their resignation to join the competition in a matter of days.
I’ve already drafted the resignation letter.
I manage by being scandinavian. It’s not as bad here.

Ask Lemmy@lemmy.world•What's the smartest or most insightful thing you figured out as a kid that stays with you today?
1·3 years agoSimilar experience. Got in a bad accident when I was 15, entirely my own doing. That’s when I learned that some mistakes and their injuries are permanent.
I don’t do blunts anymore, but I’ll happily take the beer and a wedge of blue cheese instead.
Stomach full, balls empty, and peaceful surroundings
Not only home server… this gif is 50% of my job description.
At least the UK one is blunt. I’m trying, without success, to find a picture of the old style telephone (and my modem) connectors we had here in Norway. Imagine the UK power plug, but the pins are pointy. I’ve drawn blood stepping on these. I would run a marathon on Lego to avoid stepping on one of those again. Luckily they were gradually replaced by wallmounted RJ11 (or RJ45 if you had ISDN) during the 90’s.
EDIT: Found it.
Stepping on one feels like getting shanked under your foot by Poseidon and his trident.
UK are safest, EU are both practical and almost as safe (as it supports a variety of plugs, both with and without grounding), and US is complete and utter garbage built for garbage voltage. Plus, the US one looks scared.

Asklemmy@lemmy.ml•Do your colleagues celebrate System Administrator Appreciation Day ?
0·3 years agoNo. But I am owed a beer for every project I show up to. Happens around twice per year.
Before a project that involved outfitting a survey ship headed for the Mediterranean, this conversation took place: (paraphrasing)
Me: This storage cluster is based on 10gig/s network. I don’t think the data processors will get the throughput they require.
Chief tech: I tallied up the data transfers, and the time available should suffice with 10g/s.
Me: Did you account for the fact that they duplicate the data and transfer a lot of it twice?
Chief tech: No. But I’ll tell them not to do that.
Some time goes by. Project starts, 1PB of data is collected, and processing is starting up, scheduled to complete everything shortly before they arrive back in the home port. Then my phone rings.
Project manager: Throughput speeds are too slow. Is there anything that can be done, or do we have to eat the daily fine for being too late?
Me: How much is the daily fine?
PM: (number) USD
Me: I’ll make the purchase req now for one tenth of the daily sum. That should increase the throuput.
PM: Hardware install involved?
Me: Yes. I’ll order, configure, and document everything for the chief tech to plug&play during their refuel stop.
PM: I owe you a beer for the next projects.
The extra cost wasn’t that much, considering it was the same upgrade I recommended before project startup anyway. We just had to pay for express freight from the vendor to my home, and from my home down to the ship. Long story short, it worked out. A Mellanox 2100 was shipped down to Malta, and installed by the crew, and it worked out of the box. I was worried about the extensive VLAN and LACP setup in play. But as that setup was my design, I managed to wing it when preparing this switch. I had been using the production cluster for some testing earlier, so it already had the necessary kernel modules for the 100gig cards. The processors had everything wrapped up and written to tape the day before arriving back home. The night of arrival there was a project completion dinner for the crew and us field service personnel. I drank for free that night. I don’t remember it all, except that it was fun, and that the only reason why I called it a night at 0300 was because the hotel bar was closed.
To the chief techs defense, he wasn’t that wrong. He’d made a reasonable estimate based on the numbers he had available. Unfortunately he didn’t have all the numbers, as well as give the processors some head room for fudge factor. This chief tech was mostly experienced in only providing raw dataand thus working without the processing aspect.







I was thinking that, but figured I’d go for input data instead for the sake of variation.
