That is what I was thinking, yes.

In my case just disable IPv6 in WiFi is enough.

sysctl looks like the most universal way.

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

I tried the same setup with Ubuntu 24.04.1 desktop live system and I can replicate this IP leak issue, I guess I will have to disable IPv6.

You setup Wireguard server on the VPS with both IPv4 and IPv6. Then you connect both your computer and IPv6-only server to the Wireguard server. After connection, you can connect to the VPN through IP address assigned by wireguard.

Personally have good experience with https://github.com/Nyr/wireguard-install, there are other script that are available by searching “wireguard setup script github”.

Note: By default Wireguard config generated will route every bit of traffic through Wireguard (which will be slower and probably not wanted in this situation), to change that change AllowedIPs field in Wireguard config, lets say all your machines are assigned 1.2.3.xxx as IP address, to only access other 1.2.3.xxx IP through wireguard, change the config to AllowedIPs = 1.2.3.0/24.

Host a website that needs to be accessible from your own machine or public?

Former situation: Can be solved by setup reverse proxy on the other VPS, or join machines to a VPN server (like tailscale, Zertoier or Wireguard server)

Later situation: Cloudflare or other CDN, setup reverse proxy on the other VPS.

Less accessible option but available for public: Tor or I2P

Great, if you need to SSH into Ipv6 only machine, SSH has -J flag which can be used to specify “jump host” (basically run SSH through SSH)

I am born too late to understand what Y2K problem was, this (the result) might be what people thought could happen.

I9 14900k…bad news for you, 13th and 14th gen I9 is unstable, crashes.

Suggestion: Wait for 15th gen or AMD 9000 series CPU to come out.

I remember trying Retroshare… no offline message is the biggest obstacle.

try ncdu?

sudo ncdu --one-file-system /

Forgot to answer this question, yes I think it would work.

Yes, speed would be much slower.

Yes, you can host a normal website through tor.

AFAIK tor websites (onion service) doesn’t require exit node, and no one knows your IP unless you are unlucky enough all nodes you connected are controlled by same entity.

I am pretty sure you can set your own DNS server in Android.

I think most up-to-date OpenWrt routers can do later (with normal, unencrypted DNS requests), see https://openwrt.org/docs/guide-user/firewall/fw3_configurations/intercept_dns.

The model you mentioned (Flint 2) is supported by OpenWrt.

route ipv6 dns to a destination of my choice

Does this mean setting custom DNS server (so devices using DHCP picks up what DNS server you want them to use) or intercept DNS requests (MITM or use firewall rule to drop outbound 53 port requests)?

One thing notable of Sierra Forest is that the CPUs don’t have SMT (only 1 thread per core), so in theory it doesn’t suffer from speculative execution attacks.

Epyc CPUs still provides more PCIE lanes, which is crucial for GPUs.

ASUSTOR has NAS that can have up to 12 NVME SSDs (but speed is very limited by PCIE lanes).

NVME SSDs are still very expensive compares to HDD.

NAS that have many HDD bays are expensive but designed for easy setup and easy management.

Fractal Design Define 7 (XL) can have up to 18 HDDs by design, but then you will need to search for PCIE to SATA cards and PSU that have many SATA connectors (for example RM850x/RM1000x) and Molex to SATA cables.

FSP CMT370 is a much cheaper case with up to 3.5" HDD *9 or 2.5" SSD *10 but it’s not on amazon, it probably doesn’t sell to western world.

SAS drive enclosures (and SAS cards) are also an option, but the cages might be very loud because they are designed for servers that also are very loud.

Important things about dual booting:

1. Configure your Windows to use UTC time https://wiki.archlinux.org/title/System_time#UTC_in_Microsoft_Windows

2. Disable “Fast startup” in Windows (can possibly cause hardware issues if not disabled and it really doesn’t improve things in computers with SSD)
