How to rebuild the google cloud Compute Engine VM instance like Linode VPS

google-compute-enginelinode

I am going to migrate my server from Linode to Google Cloud recently. When I am testing the google cloud Compute Engine VM instance, I can not find out the rebuild button like Linode.

Now I did some wrong operation on my VM instance, so I need to rebuild it. I don't want to delete it because I don't want to change the IP address.

I have tried the "reset" operation, but it is useless. I

Unfortunately Google Cloud Platform does not have the rebuild button. As I understand you don't want to loose your external IP address. I recommend you to reserve the ephemeral IP address of your actual instance, create a new one with a screenshot and then assign the reserved IP address.

Here are the steps:

Go to the External IP addresses page in the GCP Console. In the Type column, change the address type to Static for the IP address you want to promote. Provide a name for the new static IP address and click Reserve.
Stop the old instance.
Create a new instance with the snapshot and select the reserved IP address.

By default there is a start up script which sets the hostname according to the metadata of that instance.

Sets the hostname from the metadata server via DHCP exit hooks.

How to unblock the IP after failed sftp login attempts to google cloud compute instance

Joinning the party years later, but someone could benefit from this.

Looks like every ubuntu image has sshguard installed, after a few failed SSH login attempts your IP gets banned/blocked.

You need to connect to your instance from another ip, or use the ssh connection inside web-console from google compute engine.

What you can do is check if your ip has been banned:

sudo iptables --list sshguard --line-numbers --numeric | grep [you.ip.goes.here]

On the output you will have a line with a number at the beginning, that line must be removed (replace [N] with that line number):

sudo iptables --delete sshguard [N]

Then you should be able to connect to your server again.

There are people that suggest adding the ip to the sshguard white list and then restarting the sshguard service... I didn't try it because my i think my solution is safer given the fact that my ip can change. If you happen to need a fixed IP being white listed of solution, comment is here:
