GNUnet Name System not working (as expected)

[Tanguy LE CARROUR]

Hello GNUnet,

I'm not reporting this into the bug tracker (yet), because (good) chances
are the problem exists between the chair and keyboard…

I'm testing the newly available GNUnet 0.16.3 on Guix, starting with the
GNS. I have a single-user setup, without a stand-alone database.

I'm following the [How to use GNUnet - in a 
nutshell](https://www.gnunet.org/en/use.html)
documentation.

On computer_1 (logs at the bottom of the email):

```console
$ gnunet-arm --start
$ gnunet-core
# connected to some peers
$ gnunet-identity --create computer_1
$ gnunet-identity --display
computer_1 - 000G004515E30YC1WTB7X51H95NGVEDK8974FS3DTPCREQT2KJN35ARRG4 - ECDSA
$ gnunet-namestore \
  --zone computer_1 \
  --add \
  --expiration "1 d" \
  --public \
  --type A \
  --name ccc \
  --value 195.54.164.39
$ gnunet-gns --type A --lookup ccc.computer_1
ccc.computer_1:
Got `A' record: 195.54.164.39
```

On computer_2 (logs at the bottom of the email):

```console
$ gnunet-arm --start
$ gnunet-core
# connected to some peers
$ gnunet-identity --create computer_2
$ gnunet-namestore \
  --zone computer_2 \
  --add \
  --expiration never \
  --public \
  --type PKEY \
  --name computer_1 \
  --value 000G004515E30YC1WTB7X51H95NGVEDK8974FS3DTPCREQT2KJN35ARRG4
$ gnunet-gns --type A --lookup ccc.computer_1.computer_2
# … hangs forever
```

I was expecting to see `Got `A' record: 195.54.164.39`.

Am I doing something wrong?

It could be useful to provide, in the "how to use GNUnet",
a real GNS record within a "public" zone so anyone could add it to her
namestore and look it up without having to set up a second host, IMHO.

Best regards,

Tanguy
