(#lz6e7ra) @mckinley@twtxt.net To be honest, Iâm not doing that much computer stuff at the moment. After work, Iâm usually heading right for my bass. đ (Or Netflix. đ)
(#m6xngra) @mutefall@twtxt.net IIRC, we gave Juniper a try a while back. đ€ Something wasnât right, but I donât remember anymore what it was (probably the API not being available or not good enough?). đ«€ But this was 5 years ago or more, maybe it has changed âŠ
I hope we can stay with MikroTik for a while. Changing switches is not that much fun. đ
So, monkeypox. Surely, that wonât be the next pandemic, eh? đ€Ł đ
(#m6xngra) @xuu@txt.sour.is Sad but true. đ€Ł
(#m6xngra) @prologic@twtxt.net Iâve tcpdumpâed and wiresharkâed the shit out of this. đ Itâs not very helpful. Iâd need to gain insight into the decision making of the switch itself. Why does it drop certain packets? Thatâs almost impossible to find out (unless it happens to be included in the switchâs logs, which it usually isnât).
Like @mutefall@twtxt.net said, itâs 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. đ€Ł Sometimes this approach works, sometimes it doesnât âŠ
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 â instead of using the switchâs web UI or SSH, like some cave men. That should make our life much easier.
Honestly, all the switches Iâve 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 canât afford that.
(#jjjxnzq) @mckinley@mckinley.cc đ€Ł
(#m6xngra) @prologic@twtxt.net 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 â 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 doesnât 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 havenât figured out this issue.
(#j2hiwdq) @mckinley@twtxt.net Nice, thanks!
(#j2hiwdq) @mckinley@mckinley.cc Lovely! đ I wonder which distro that is. Itâs a pretty new kernel and itâs running systemd, so it canât be something ancient. đ€
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 thereâs that.
(#itqyskq) @lyse@lyse.isobeef.org ⊠and, yeah, I didnât follow Die Anstalt for quite a while, either. I think it got too depressing at some point and then I stopped. đ
(#itqyskq) @lyse@lyse.isobeef.org Nah, I meant Tresenlesen. They did a reunion recently: https://www.youtube.com/watch?v=ghkLLpXyols So itâs really mostly the two guys sitting there and reading from their notes. đ„Ž (Itâs still good, though!)
(#gioykcq) @prologic@twtxt.net That sure is a lot of water. :o
(#itqyskq) @lyse@lyse.isobeef.org Me neither. I just knew him from âDie Anstaltâ and such. (Honestly, Iâm not sure if itâs my cup of tea, because they literally focus a lot on reading stuff ⊠I like it more when theyâre speaking freely. %)
(#3gtuw3a) @prologic@twtxt.net What the heck, thatâs crazy. đ
