Time to consider TIME, in due time

Monitor DNS for device identification.
Here are some popular DNS domains for time
*.pool.ntp.org time.google.com time.apple.com time.android.com api.rokutime.com time.cloudflare.com time.windows.com time.nist.gov

Could intercept and redirect to local ntp as described here: forum.openwrt.org/t/redirect-outgoing-ntp-traffic-to-an-internal-ntp-server/161223/8

Extract Google Authenticator keys

Generally, you can’t. You can only transfer them to a new phone by using export to generate QR code then add them to new phone like you would any other QR code.
However, if you do have root, you can. The talented authors from protectimus have documented how.
Rooting your phone is a bozo no no.
This is a more time and effort consuming way to transfer Google Authenticator key to the other smartphone. It requires you to have root access to the smartphones.
To extract the secret keys manually you need to give adb root access, this is easily done with an app like [root] adbd Insecure if you’ve got stock ROM. And in case you happen to have custom ROM you might already have the necessary root access adb, so no additional apps are needed.
Set adb onto insecure mode with the application or directly, connect the smartphone to your PC or laptop and copy the Google Authenticator databases to the computer using the commands.
This is the pathname:
adb pull /data/data/com.google.android.apps.authenticator2/databases/databases
After the file is copied you can open it and see the keys using these sqlite editor commands:
sqlite3 ./databases
select * from accounts;
Now you have your secret keys and can add them to your new device.

VPNAPI.IO Is an IP on VPN, Tor

VPNAPI.IO will report details on an IP Address. It will identify if it is on VPN, TOR, Proxy or Relay as well as GEO and ASN data.
There is a free account that is limited to 1,000 queries per day. As the name implies, it works via an API.

Chromebook sucks, no text editor as guest

I would like to use a chromebook without logging in. This is a problem because to do anything special or extra, you need an extension. To add an extension, you need to login. This gives Google more opportunities to invade your privacy.
Here is a neat trick that lets you just start editing in a browser window. [image: image.png] Unfortunately, you can save the content. Or, open an existing text file.

OpenWrt 1:1 NAT, multiple external IP

Instead of Nat’ing everything to the router IP you may want to NAT to many IP Addresses.
A couple of tips. In the network config add IP addresses on the WAN interface Configure ‘redirect’ sections in the Firewall config file Specify gateway and DNS on the WAN interface and enable masquerading on the LAN zone.

The innernet

Not a type. Innernet is an open source product for managing a community of wireguard peers.
‘Think of innernet as an opinionated configuration system on top of WireGuard that comes with some added features to make life easy, and is friendly with various sizes of networks: one for your organization, one for your project, one for your social circle to create an idealistic alternate internet universe — your imagination’s the limit.’
innernet establishes three main primitives in defining your network:
– Peers: machines on the network, – CIDRs: peer groups based on IP blocks, and – Associations: connections between CIDRs for access control.
