-After a boot, the encrypted root partition will have to be unlocked. This is done by accessing the server via SSH with user root on port 2222.
+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@nachtigall.pub.solar -p2222
+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.
