Stavo imparando a configurare un server Debian e familiarizzando con le comuni righe di comando.
Tuttavia, dopo aver eseguito il reboot comando in SSH, le mie successive connessioni SSH sono state rifiutate e non ho assolutamente accesso al server.
Sono stato in grado di ping il server. Ho tentato di riavviare anche tramite l'interfaccia cloud di Google, tuttavia non sono ancora riuscito a connettermi correttamente.
Avendo questo come server cloud, non ho alcun accesso fisico al server. La soluzione che mi sembra di vedere è riconfigurare le impostazioni SSH che non posso senza accedere.
Quali sono le possibili alternative che ho ora o ricreare una nuova istanza è l'unica soluzione?
Risposta accettata:
La soluzione migliore è creare la chiave manualmente con la console gcloud:
[email protected]:~$
[email protected]:~$ gcloud compute config-ssh

You should now be able to use ssh/scp with your instances.
For example, try running:
$ ssh <instance>.<location>.<project>
