Saya sedang belajar mengonfigurasi server Debian dan membiasakan diri dengan baris perintah umum.
Namun, setelah menjalankan reboot perintah di SSH, koneksi SSH saya berikutnya ditolak dan saya sama sekali tidak memiliki akses ke server.
Saya dapat ping server. Saya mencoba mem-boot ulang melalui antarmuka cloud Google juga, namun saya tetap tidak berhasil terhubung.
Memiliki ini sebagai server cloud, saya tidak memiliki akses fisik ke server. Solusi yang sepertinya saya lihat adalah mengonfigurasi ulang pengaturan SSH yang tidak dapat saya lakukan tanpa login.
Apa alternatif yang mungkin saya miliki sekarang atau membuat ulang instance baru adalah satu-satunya solusi?

Taruhan terbaik Anda adalah membuat kunci secara manual dengan konsol gcloud:

[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>
