Hello, I have a rather complicated need to use a gre tunnel and I am having difficulty getting it working. The tunnel is between my home server and Oracle VM. Below is a picture of the topology with config.

Pings between the home server and Oracle VM over the gre tunnel do not seem to be going through as evidenced by tcpdump. I do notice however that the firewall has the correct state table showing that address translation. I am certain that both machines' firewalls are not dropping packets because iptables is not showing anything dropped. I am at a loss here so I welcome any ideas.

I'm struggling with CSS Flexbox. Each time I think I'm about to get it in an aha momet, I'm actually two steps backwards. I'm taking The Odin Project course and I'm at the phase where I am building the landing page. I've worked on it for 16 straight hours and I'm almost finished. It just looks like shit on a small screen but in fairness, the curriculum did mention that. Otherwise, what I have looks like the goal. I did one or two extra easy touches.

Okay so one question: when is it better to use flex-direction: column and when is it better to use flex-direction row? I'm seriously confused.

I just looked on the instance list and my instance is no longer listed. Does this mean I have been blocked? I just upgraded to 0.18.4. Thanks in advance.

I know this has probably been asked before but I am currently using Arch and wondering if my choice is the best for gaming. What are the thoughts from the community? I have an AMD Ryzen 7 processor with 64 gigs of RAM and a decent AMD GPU. Gaming seems to be okay on Arch but I am wondering if I've overlooked something better. Thank you in advance.

Hey! Does anybody have any information about if and when a company might offer ARM64 for general desktop use? I would like to build my own in the same way that I might build a desktop PC out of an Intel or AMD processor.

I'm looking for a recommendation on a full bluetooth headset, not earbuds. I would prefer if it had the boom style protruding microphone and that it would support an easily replaceable battery. I am sick of discarding bluetooth headsets due to battery problems as it's not environmentally friendly. Does one exist in the sub-80 dollar range? Thanks in advance.

EDIT: Poor troubleshooting on my part. I missed the part in the dmesg about missing the firmware. I installed the firmware through AUR and everything works as it should. I need to be better than this .....

Okay, so I am ready to tear my hair out over this one. I've followed the Arch wiki to the letter and none of my devices are being discovered. The dmesg command shows my internal bluetooth adapter and blueberry recognizes the adapter. What gives? I don't know where to go to troubleshoot from here. Any ideas are welcome.

I am looking into getting started in web development and I came across The Odin Project. Unfortunately, I don't have the money to pay for a course right now. I currently work in a senior desktop support and systems admin role and I am seeking to pivot into web development. Is this realistic? What advice or websites would you recommend for me? Thank you very much in advance!

Hello fellow self-hosters. Is it possible to use NGINX as a proxy for an IMAP service where the IMAP server is located on a different host? I have a cloud VPS running NGINX which is connected to my home network via a WireGuard tunnel. What I would like to do is run the IMAP server (Dovecot) in my own network and have NGINX proxy the connection. I have tried doing searches based on this but the examples don't show how to specify the IMAP server for the connection to be redirected to for the lack of a better phrase. I know streaming is possible. Would this be the way to do?

I would love an example to go on. Thanks very much!

EDIT: With thanks to u/code@lemmy.mayes.io, I have a solution for cleaning up the one table that is growing ridiculously in size and that is the activity table. A TRUNCATE activity; command cleaned that right up. A word of caution is in order because the Lemmy instance must be shutdown completely and only the postgres container running if you're using docker.

As a new Lemmy admin, I think I really need to learn PostgreSQL administration because I need a way to keep my database from ballooning in size and there are no management tools built yet for it. Would someone be so kind as to recommend a good website for learning PostgreSQL? This would also help me maintain my mastodon instance.
