# Unlocking the root partition on boot
After a reboot, the encrypted ZFS pool will have to be unlocked. This is done by accessing the server via SSH with user `root` on port 2222.
Nachtigall:
```
ssh root@138.201.80.102 -p2222
```
Metronom:
```
ssh root@49.13.236.167 -p2222
```
After connecting, paste the crypt passphrase you can find in the shared keepass. This will disconnect the SSH session right away and the server will keep booting into stage 2.

# Unlocking the ZFS pool on boot
After a reboot, the encrypted ZFS pool will have to be unlocked. This is done by
accessing the server via SSH as user `root` on port 2222.
Nachtigall:
```
ssh root@nachtigall.pub.solar -p2222
```
Metronom:
```
ssh root@metronom.pub.solar -p2222
```
After connecting, paste the encryption passphrase you can find in the shared
keepass. This will disconnect the SSH session immediately and the server will
continue to boot into stage 2.
