1. **SSH Public key**: self-explanatory. Add your public key to your user attrset under `sshPubKeys`.
2. **Wireguard device**: each wireguard device has two parts: the public key and the IP addresses it should have in the wireguard network. The pub.solar wireguard network is spaced under `10.7.6.0/24` and `fd00:fae:fae:fae:fae::/80`. To add your device, it's best to choose a free number between 200 and 255 and use that in both the ipv4 and ipv6 ranges: `10.7.6.<ip-address>/32` `fd00:fae:fae:fae:fae:<ip-address>::/96`. For more information on how to generate keypairs, see [the NixOS Wireguard docs](https://nixos.wiki/wiki/WireGuard#Generate_keypair).
One can access our hosts using this domain scheme:
```
ssh barkeeper@<hostname>.wg.pub.solar
```
So, for example for `nachtigall`:
```
ssh barkeeper@nachtigall.wg.pub.solar
```

# Delete accounts without verified email address
### Keycloak
Required:
- auth.pub.solar admin-cli service user credentials
- [SSH access to host `nachtigall`](../administrative-access.md#ssh-access)
Run following after SSH'ing to `nachtigall`.
Credentials for the following command are in keepass. Create a keycloak
config/credentials file at `/tmp/kcadm.config`:
```
sudo --user keycloak kcadm.sh config credentials \
--config /tmp/kcadm.config \
--server https://auth.pub.solar \
--realm pub.solar \
--client admin-cli
```
Get list of accounts without a verified email address:
```
sudo --user keycloak kcadm.sh get \
--config /tmp/kcadm.config \
users \
--realm pub.solar \
--query emailVerified=false \
> /tmp/keycloak-unverified-accounts
```
Review list of accounts, especially check `createdTimestamp` if any accounts
were created in the past 2 days. If so, delete those from the
`/tmp/keycloak-unverified-accounts` file.
```
createdTimestamps=( $( nix run nixpkgs#jq -- -r '.[].createdTimestamp' < /tmp/keycloak-unverified-accounts ) )
# timestamps are in nanoseconds since epoch, so we need to strip the last three digits
for timestamp in ${createdTimestamps[@]}; do date --date="@${timestamp::-3}"; done
vim /tmp/keycloak-unverified-accounts
```
Check how many accounts are going to be deleted:
```
jq -r '.[].id' < /tmp/keycloak-unverified-accounts | wc -l
```
```
jq -r '.[].id' < /tmp/keycloak-unverified-accounts > /tmp/keycloak-unverified-account-ids
```
Final check before deletion (dry-run):
```
for id in $(cat /tmp/keycloak-unverified-account-ids)
do
echo sudo --user keycloak kcadm.sh delete \
--config /tmp/kcadm.config \
users/$id \
--realm pub.solar
done
```
THIS WILL DELETE ACCOUNTS:
```
for id in $(cat /tmp/keycloak-unverified-account-ids)
do
sudo --user keycloak kcadm.sh delete \
--config /tmp/kcadm.config \
users/$id \
--realm pub.solar
done
```
