RaspberryPi

Hello friends, as I promised in my previous post I’m going to tell you about configuring GoogleWiFi router with a Raspberry Pi server acting as DHCP and DNS server / VPN gateway. While part related to NordVPN is vendor specific I feel it would not be too hard to use similar setup with any VPN provider. Feel free to skip VPN related part.

I’m not sponsored by NordVPN, instructions provided as is and as any information from the Internet should be used carefully.

With lot of time spent home during stay-at-home order active in my area I decided it’s a time to overhaul my home network setup.

I think I’ll get into details in the following posts but at this time I want to tell about an issue with DHCP leases I was able to track down using tcpdump.

• Why unlock using flash drive: Because you don’t have keyboard or monitor connected to your RPi, do you?
• Information: I was using Pezz’s gist, which helped me a lot. Thank you very much, Pezz.
• Why Arch linux: because I wanted to try Arch, default kernels of Raspbian and Pidora lack(lacked? Maybe already have) needed encryption modules.

SD card preparation

Download Arch linux image from here: RPi downloads

On your desktop check list of devices:

$ ls -lah /dev | grep sd

brw-rw---T   1 root disk      8,   0 Aug 11 15:43 sda
brw-rw---T   1 root disk      8,   1 Aug 11 15:43 sda1
brw-rw---T   1 root disk      8,   2 Aug 11 15:43 sda2
brw-rw---T   1 root disk      8,   3 Aug 11 15:43 sda3
brw-rw---T   1 root disk      8,   4 Aug 11 15:43 sda4

Now insert SD card into card reader on desktop, and check list once again. You’ll see a new device we’ll write Arch linux image to.
