google cloud vm ssh.network 错误：连接超时

Question

I'm trying to ssh into a GCP Linux VM from my local Windows 10 machine using google cloud SDK.

I have two wifi.networks at home. When I run the command gcloud compute ssh VM_name , I can connect to the VM through only one of the.networks. On the other.network, I receive the following error from puTTy:

puTTy FATAL ERROR: Network error. Connection timed out.

Both.networks are from the same inte.net service provider. Why is it not connecting through one of them? Which settings should I look into?

Answer 1

As per this doc To address a common fatal error that many users have experienced using the PuTTY software, which goes as follows: A fatal error occurs when the software throws an error without warning or saving its state, rendering the user unable to carry out any additional actions.

Resolution steps :

Confirm Ip Address

First things first, make sure the client machine can get to the remote server. A ping test is the most straightforward method for achieving this. Pinging the server from the client will guarantee that the two devices have a valid.network connection.

Replace the IP address of the remote PC you want to SSH with the following cmdlet in the Command Prompt.

If the ping does not produce a response, either the machine is not connected to your.network or the server's firewall is active, preventing both the ping and the SSH connection.

Disable Windows Firewall

By default, Windows firewall blocks most ports. Follow these steps to disable the firewall on your server by logging in through the portal or physically accessing the machine:

1.In the Run Command box, type firewall.cpl to launch Windows Firewall.

2.Now, from the left, select Turn Windows Defender Firewall on or off.

3.Now, under each of the visible.network profiles, select Turn off Windows Defender Firewall. To save the changes, click OK when finished.

Check once more to see if you can ping the client machine now. If this is the case, then try the SSH connection once more to see if it works. Continue implementing the following solutions to alleviate the issue if it still does not.

Check if SSH is Enabled

1.Go to the following locations:

Settings app >> Apps >> Optional features

2.In front of the phrase "Add an optional feature," select View features.

3.Find "Open" in the "Add an optional feature" window. Select OpenSSH Server from the search results, and then click Next.

4.Click Install in the following window.

5.After that, the feature will be installed. The dependent services must be manually enabled when this occurs. In the Run Command box, type services.msc to open the Services console.

6.To start the service, select Automatic from the "Startup type" drop-down menu in the Properties window and then click Start. To save the changes, click Apply and OK when it does.

You should be able to use PuTTY to connect to this machine from the client computer now that SSH is set up.
