Buckle up, @lyse@lyse.isobeef.org (and maybe @carsten@yarn.zn80.net). More heavy thunderstorms are on their way.
@mckinley@twtxt.net To be honest, I’m not doing that much computer stuff at the moment. After work, I’m usually heading right for my bass. 👌 (Or Netflix. 😂)
@mutefall IIRC, we gave Juniper a try a while back. 🤔 Something wasn’t right, but I don’t remember anymore what it was (probably the API not being available or not good enough?). 🫤 But this was 5 years ago or more, maybe it has changed …
I hope we can stay with MikroTik for a while. Changing switches is not that much fun. 😂
So, monkeypox. Surely, that won’t be the next pandemic, eh? 🤣 😭
@xuu@txt.sour.is Sad but true. 🤣
@prologic I’ve tcpdump’ed and wireshark’ed the shit out of this. 😂 It’s not very helpful. I’d need to gain insight into the decision making of the switch itself. Why does it drop certain packets? That’s almost impossible to find out (unless it happens to be included in the switch’s logs, which it usually isn’t).
Like @mutefall said, it’s usually some kind of misconfiguration. Hence you begin to dump the entire switch config into a file and then run diff
against the config of a working switch. 🤣 Sometimes this approach works, sometimes it doesn’t …
We recently changed from Cisco to MikroTik switches. At least those switches offer some kind of basic API, which means we can configure them via our config management – instead of using the switch’s web UI or SSH, like some cave men. That should make our life much easier.
Honestly, all the switches I’ve seen so far were total crap. So far, MikroTik is the best thing. Maybe there are actually good switches out there, but they probably cost a ton of money, and we can’t afford that.
@prologic In this particular case: Figuring out why a switch decided not to forward ARP broadcasts to certain switch ports. Like, you connect two devices to the switch ports 3 and 4 and they can ping
each other – but when you move one of them to port 5, no ping
anymore. So, rather low-level stuff.
Or, we have another switch that intermittently doesn’t respond on its management IP anymore (even when you connect your laptop directly to the switch with no other networking hardware in between). I still haven’t figured out this issue.
@mckinley Nice, thanks!
@mckinley@mckinley.cc Lovely! 😁 I wonder which distro that is. It’s a pretty new kernel and it’s running systemd, so it can’t be something ancient. 🤔
Spent the last few days debugging network issues at work.
Exhausting. You never get a full picture. You poke a little here, poke a little there, … Form a hypothesis and test it. Eventually, maybe, you can narrow it down a bit to some segment or even some component.
A very time consuming process. Even more so if you try not to cause downtimes for your users.
I want a magical device that allows me to look inside a cable/fibre.
But hey, at least we got rid of a bunch of Cisco switches in the process. So there’s that.
@lyse@lyse.isobeef.org … and, yeah, I didn’t follow Die Anstalt for quite a while, either. I think it got too depressing at some point and then I stopped. 😅
@lyse@lyse.isobeef.org Nah, I meant Tresenlesen. They did a reunion recently: https://www.youtube.com/watch?v=ghkLLpXyols So it’s really mostly the two guys sitting there and reading from their notes. 🥴 (It’s still good, though!)
@prologic@twtxt.net That sure is a lot of water. :o
@lyse@lyse.isobeef.org Me neither. I just knew him from “Die Anstalt” and such. (Honestly, I’m not sure if it’s my cup of tea, because they literally focus a lot on reading stuff … I like it more when they’re speaking freely. %)
@prologic What the heck, that’s crazy. 😁
@lyse@lyse.isobeef.org Working fine on my end. 👌
@lyse@lyse.isobeef.org I don’t think it went wrong. That’s the best you can get if you can’t change the exposure time. 😅
(And if you can change it, you’ll see nothing but the moon, no clouds anymore. Boom, you have to go for HDR. It’s really not that easy to take pictures of this little rock floating through space.)
@prologic God dammit 🤣
@lyse@lyse.isobeef.org It’d take a bit over an hour, they say. So they’re assuming a speed around 16kph – is that realistic?! 😅
Right, going with a bike on a highway isn’t going to be fun if things stay as they are now. But imagine the number of cars reduced to 10% and they’re only allowed to go ~30kph or maybe 50kph … Yeah, it’s never going to happen, I know. 😑
@lyse@lyse.isobeef.org Whoops, I forgot about that reply. But now that you’ve mentioned bikes in the other thread, I remembered … 😅
This is the height profile that Google has calculated: Looks exhausting, if you ask me. I never tried, though, I don’t even own a bike at the moment.
Fun fact: It’s 21km if you’re going by bike. Everything is optimized towards cars. I wish they would just dedicate one lane on the highway for bikes and the other lane has a limit of 30kph. Or something like that. 😐
And then, when I arrive at the office, I’d have no idea where to put my bike. If it’s just me, I’d find a spot, sure – but what if everyone does it? Turns out, it’s a bit of an unsolved problem. (But hey, if we wanted to do this, if we wanted to get people to use bikes, we’d find a solution. Even those underground parking garages in the video sound like a dream to me.)
@lyse@lyse.isobeef.org I’ve never seen a bike like that. 😲 Actual chairs instead of those tiny saddles – is that as comfortable as I think it is? 😅
@mckinley Ah, thanks, I missed that. (Yup, <link>
would be very handy – even though the major browsers ignore it these days …)
@lyse@lyse.isobeef.org Mostly, but I have some more debugging to do. Means: More time in the office. 😑
