I disabled port 22 by mistake on my cloud server and now am not able to ssh it.

I unexpectedly closed port 22 by ufw command (firewall level). Is there any way to login that server? The server is working, but not able to login. Is there any way to disable ufw ?

Alternatively, how can do magic reboot this machine?

    If this is a "cloud" server, please give more information in your original question or consult you cloud VPS provider's documentation on how to connect to your server's console or on how to modify the disk image of your server. Aug 22 '19 at 7:15
  • Hi Jasil, can you give us more details, please? What's the context and share exactly what command you tried to run.

  • Hi Jasil, what cloud service is hosting the server? If it's something like AWS or Azure or GCP it's easy to reboot the instance.

You need either physical access to the server or console access. It would be really bad if it was possible to reenable access to port without having access to the server, any attacker would be able to do it

    Or you need management access to the account in the cloud service hosting the instance/server.
