Using the ledger nano s with Monero

Ledger nano s

Ledger nano s initialization

After unboxing the ledger, I just connected it via the USB cable. It powered up perfectly and started the initialization process. The ledger asked to set a PIN, then I had to copy the seed word by word and confirm it by repeating it word by word.

I had a short look into the settings and naively tried to create a HW wallet using monero-wallet-cli (see below for the actual command).

Getting the ledger recognized by the system

It turned out the ledger nano s was not detected by my linux system (ubuntu 18.04), so I searched the internet and found a script (see below) from

Text file is busy

When executing a file whose permissions were changed earlier, a Text file is busy error could appear.

RUN cd scripts/test_env \

    && ./test.prepareapp.sh

It helps to add sync after changing permissions on the file:

getting tls pubkey value for DNS over TLS certificates

Getting the tls pubkey for a DNS over TLS address

I added cloudflare-dns.com to my stubby.yml and couldn't find any information on the value of the tls_pubkey_pinset

tls_pubkey_pinset:
  - digest: "sha256"
    value: MISSING

Although I could find some examples, the value seemed to be wrong.
