Tapo camera ONVIF not working

Larry Skye — Sat, 31 Aug 2024 19:22:27 GMT

Basically to get your Tapo Camera connected to home assistant:

Go to your camera on the Tapo App, Storage & Recording -> Local Recording -> off.

Try again, the ONVIF port seems to be 2020. If that doesn't help, try removing the SD card and rebooting, or disabling the tapo care stuff...

PS: Firefox Picture-in-Picture is pretty cool!

Also YouTube, fix your website in Firefox.

Hello Isle of Code.

🕵️ netsec from tier zero

Larry Skye — Sun, 17 Apr 2022 22:59:02 GMT

Just give up doing port forwards, seriously

remember Himatchi? (Developed by Alex Pankratov in 2004, used a lot by gamers for WAN/LAN games?)

cringe

The idea is sound, there is no reason why networks nowadays should be constrained by the physical mapping of a network. And there's a new player on the market that seems to be checking a lot of the boxes and gaining momentum.

Zerotier

ZeroTier combines the capabilities of VPN and SD-WAN, simplifying network management
~ dec0dOS/zero-ui/README#Wait, I haven't heard about ZeroTier yet

I can confirm it works nicely. Why even bother with reverse ssh tunnels?! Just remember to ☑ the device you want to accept onto the network :P

It's so simple you'll forget about it once it's in place. Zerotier free allows up to 50 devices (1 admin user) on a private network for free.. and there's a way to host it yourself for free + have a friendly UI.

If you're still not convinced:

Mikrotik

Since 2021/2022, there's Zerotier support, both as client and controller for MikroTik routers!

This opens an interesting door, any device on your physical network would be able to talk to any device on a remote physical network as long as both are members of the same Zerotier network.

RouterOS implements ZeroTier functionality in the role of a node where most of the network configuration must be done on the ZeroTier webpage dashboard. However, in situations where you would prefer to do all the configuration on your own device, RouterOS offers to host your own controller

Alternatives

Tailscale seems to be the closest direct alternative, being less decenteralized but offering SSO.

ZeroTier vs. Tailscale

As modern enterprises migrate to cloud-based services and remote work, fortified corporate walls are deteriorating, and so is the use for a traditional VPN. Network architects are embracing a new “zero trust” approach, which means physical networks cannot be trusted, and every device must always be…

Tailscale

Tailscale is a zero config VPN for building secure networks. Install on any device in minutes. Remote access from any network or physical location.

Status

It's still a work in progress, but here's the todo:

have our main laptops/smartphones networked over Zerotier ☑️
Have our home server networked over Zerotier
Install Zerotier on our router ☑️
full tunnel mode, like a VPN
Have dns
run own controller
fail-over for controller

🥒 Wanna access your home server remotely?

Larry Skye — Sun, 20 Mar 2022 17:48:00 GMT

Sometimes you don't have physical access to your machine.

Step 1 (do this while still having physical access)

Get a cheap VPS, or use the cloud, you're basically are going to want to own static IP. How come you don't have this yet? If you're a student / cheap / cloud-crazy / whatever-the-opposite-off-cloud-crazy-is.

I'll assume the WAN IP address that you own is 198.51.100.0 and that you're able to login to a Linux server that has this IP address setup using
ssh root@198.51.100.0.

So what you'll want to do from the device you want to remotely access is:

# run this on the device you want to be able to access later on, remotely
ssh -f -N -T -R22222:localhost:22 root@198.51.100.0
# it will be running in the background, you can check using:
# ps aux | grep "ssh -f"

Assuming you have ssh running on port 22, and port 22222 is available.

Step 2 (hopefully you've tested this using 3G)

So here we go, you need to get ssh access.

ssh -t root@198.51.100.0 "ssh -p 22222 user@localhost"

done.

Bonus

Remember that setting your router had that would allow you to access the router remotely? So set it to 198.51.100.0.

ssh -D 8181 root@198.51.100.0

will set up a socks5 proxy on localhost:8181, allowing you to access the web UI using the WAN IP address for your router.

Bonus 2

# to get wan address
curl https://api.ipify.org

SSH Tunnels - A Visual Guide To Port Forwarding 🧵

One of my favorite parts of SSH is tunneling. With just the regular ssh client, you can do wonders!

🍓 Raspberry Pi

Dark mode

While Raspberry Pi's are a great way to increase the compute power, interfaces and connectivity of your man-cave, they all seem to have pesky little green/red lights that ruin the atmosphere you're trying to create or even keep you awake at night!

There's an easy fix:

#Power LED off
echo none > /sys/class/leds/led1/trigger
echo 0 > /sys/class/leds/led1/brightness
#Activity LED off
echo none > /sys/class/leds/led0/trigger
echo 0 > /sys/class/leds/led0/brightness

# Add to /boot/config.txt:
# Turn OFF Network LED's

Also, no 😆 without emojis: apt install fonts-noto-color-emoji

I can confirm these things works on:

Raspberry Pi 400

Also, did you know Raspberry Pi are at least partly made in Wales?

 macOS apps I use (outdated)

Larry Skye — Sat, 26 Sep 2020 03:35:30 GMT

I don't like what Apple is doing with macOS and their devices, but there's still too much stuff I can't complain about. But don't get me wrong, no platform is better, I use Linux and Windows daily as well when it makes sense.

Make the touch bar slightly more useful using Pock

But honestly, I'd avoid one of the models with a touch bar..

Hide not commonly used icons in the system tray Using Dozer (releases)

Update May 2022

MacBookPro18,3 (MacBook Pro (14-inch, 2021)) is actually okay to use, it feels like they took the best version of their original MacBook pro lineup (MacBookPro8,1 MacEarly 2011 13") and took notes:

Aux connector on the left side
Keep MagSafe in the same spot
SD-card slot on the right
3x USB-c
HDMI connector ❤️
Battery life 🔋

Decent keyboard after heavy use, stays fairly clean.

However

music.youtube lags when you have a lot of apps open. Feels like it's switching between high power and low power CPU..

speaker pops a lot

☕️ coffee

Larry Skye — Fri, 25 Sep 2020 20:42:23 GMT

What do I know about coffee?

Nothing, I just drink a large amount (200ml - 2l) of it daily. It's also a must-buy if visiting a new place for some reason. (Only roasted whole beans, ask the locals where to go).

The following method works really well with "Starbucks Blonde Espresso Roast Whole Bean Coffee Bag". (Starbucks [mirror] / ASDA [mirror] / SE [mirror]). But I've also tried it with ASDA Extra Special Colombian Fairtrade Coffee Beans. Or any lighter roasted bean-like drop coffee [mirror].

With an AeroPress method

An AeroPress used in this way seems to be the best way for a smooth, non-bitter, almost tea-like cup of coffee. But still enjoyable. It seems to make sense looking at the ratio. A digital coffee scale is helpful.

The Aeropress was, for a long time, my go to for a quick coffee for two
- Inverted method
-Add 40g coffee
-Add 120g water (84°C)
- Stir for 10 seconds
- Steep for 50 seconds
- Flip the Aeropress at 60 seconds in, and press in a vessel of your choice
- Put the vessel with your coffee concentrate on the scales and tare
- Add 240g of water (or to your liking)
- Divide in two cups
- Enjoy
It's basically a modified version of the receipe of Tetsu Kasuya

Pour-over

This beats all the other coffee I've been offered almost everywhere. But I haven't done scientific research yet on the exact method. I'll try to update as I go along. Ginseng coffee seems to have a similar flavour profile.

V60

40g medium ground coffee

15g chicory (cover the top)

1l boiling water (preferabily not boiling (probably 90deg)

place v60 straight on thermos

no bloom; just pour in the centre

keep insulated for +4h for extra extraction

best with sugar + milk

But then again... any coffee tasted good with milk and sugar 🤷‍♂️

cold brew coffee

Best enjoyed in summer, use as light as possible roast of beans. Served potentially with tonic. More research and experimentation are required.

Doesn't have to be served cold.. can be heated up. It's the brewing that's different.

Additional thoughts

The first post on this blog had to be about coffee.
