I'm trying to connect into my VM with SSH via browser, but I'm not able to do it
This is the output I receive in the troubleshoot:
How can I solve this?
I'm attempting to find a completely remote / cloud-based development workflow.
I've created an aws free-tier ec2 instance and on that box I've been developing a gatsby site (the framework doesn't matter, the solution I'm looking for should be framework agnostic). Since the code is on another box, I can't run the dev server and then from the local computer hit localhost as I would normally.
So,
What do I need to do so that I can run gatsby develop and hit my dev server that's hosted on the ec2 box?
How do I provide public access to that endpoint?
Is it possible to provide temporary access so that when I log off of the box, it's no longer accessible?
Is there some mechanism I can put into place so that I'm the only one that can hit that endpoint?
Are there other features that I should be taking advantage to secure that endpoint?
Thanks.
I can't run the dev server and then from the local computer hit localhost as I would normally
You can. You can use ssh to tunnel your remote port to your localhost, and access the server from your localhost.
What do I need to do so that I can run gatsby develop and hit my dev server that's hosted on the ec2 box?
ssh into the dev server, run gatsby develop and either access it on localhost through ssh tunnel or make it public to access through its public IP address.
Use sshfs to mount a development folder on the dev server onto your localhost.
Alternatively, you can setup vncserver on the dev server, tunnel vnc connection using ssh, and access the dev server using through a remove desktop. Something liteweight would be good, e.g. fluxbox as a desktop environment for vnc.
Is it possible to provide temporary access so that when I log off of the box, it's no longer accessible?
yes. through ssh tunnel. You close tunnel and the access is finished.
Is there some mechanism I can put into place so that I'm the only one that can hit that endpoint?
ssh tunnel along with security group to allow ssh for your IP address only.
Are there other features that I should be taking advantage to secure that endpoint?
Security groups and ssh tunneling would be primary choices to ensure secure access to the dev server.
You can also make the endpoint public, but set security group of your dev server to allow internet access only from your IP.
You could also put the dev server in a private subnet for full separation from the internet. Use bastion host to access it or setup double ssh tunnel to your localhost.
Other way is to do all development on localhost, push code to CodeCommit and have CodePipeline manage deployment of your code to your dev server using CodeDeploy.
You can also partially eliminate ssh by using SSM Session Manager.
Hope this helps.
I am trying to fix a website that is hosted on Google Cloud Platform using VM instance. The website is giving me a connection refused error message. I have checked that the firewall rules are set up and are provided to the VM instance.
The VM external IP is static and the same IP is present on both cloud DNS and GoDaddy.
I'm also unable to SSH into the instance.
The SSH screen is stuck here and is not loading any further
I have given the necessary permissions to the instance and the user (Compute Admin, Compute Instance Admin (v1)), but still no luck.
As the instance is created from a custom image, so later, I tried creating another instance with the same config and I was able to SSH from it. So, please find some screenshots attached below if those could be of any help
netstat -a
route -n
df -h
I am new to this so any help to fix the issue and get the website up and running would be highly appreciated.
If it worked at the second attempt (2nd Instance I mean), I suspect that the SSH service hasn't started properly. I would recommend you to check the Serial Port Output, and Accessing into the Instance through the serial port in order to be able to troubleshoot it.
Note that you'll need a user to access through the serial port. If you don't have any user created, you will be able to do so using an startup-script.
Hope this helps!
So I have an Amazon EC2 Free Tier Instance with Debian Jessie. There's a software running that generates an html file I'd like to access remotely.
When connected to the instance via SSH, I can remotely open a web browser and go to 127.0.0.1:8083/index.html?PARAMETER1=...&PARAMETER2=...
Now doing this is very tedious because the browser is slow. I'd like to be able to access to this file directly using the web browser in my local machine.
How do I do this? I tried replacing 127.0.0.1 with the Public IPv4 but it won't work. Do I have to open the port?
Thanks.
You would need to open port 8083 using the security groups inbound rules for the ec2 instance. Then use the public IP to access the file.
When i click the SSH button in the Complete Engine page, the shell window pops up and it shows that the ssh keys are being migrated. After that dialog disappears, nothing happens. I get a blank page without any prompt.
If you're using Firefox (same as me). This seems to be the problem as chrome works fine. Apparently Firefox has a bug. Idk if it's an actual bug or it's done on purpose because sometimes (less times) this works on Firefox and then sometimes doesn't unless I keep and keep reopening an closing the SSH.
Instead of opening and closing every time hoping for a chance to work and or using chrome, If you have linux or in my case I have Windows subsystem for Linux on my windows computer, so I can just SSH to it.
For windows, you could use the subsystem, or use Putty (Here's a putty tutorial https://www.youtube.com/watch?v=fmh94mNQHQc on how to connect to GCC) That putty tutorial is also similar to how you can do it on the subsystem so you can still watch it for that too
It's a bug in a Chromium library that affects Firefox. Use Chrome as a workaround.
To use the browser to SSH to a GCE instance, you need to be a compute instance admin. Also, if you run that instance with a Service Account, your account need to be a Service Account user. Check this link for more information: https://cloud.google.com/compute/docs/ssh-in-browser
In addition, did you check that your firewall allows connections to SSH port (22) from Google IP ranges ?
You can find them by using these commands (see https://support.google.com/a/answer/60764)
nslookup -q=TXT _netblocks.google.com 8.8.8.8
nslookup -q=TXT _netblocks2.google.com 8.8.8.8
nslookup -q=TXT _netblocks3.google.com 8.8.8.8
You can try different methods of connecting an instance to see if the issue is underlying at SSH or somewhere else.
There are several ways to connect a Linux instance via the SSH. You can connect to an instance via the terminal. You can connect via the Cloud Console Web UI which is in general the most convenient way to connect to an instance. Also, you can use Google Cloud SDK and run below command to connect to an instance via SSH:
$ gcloud compute ssh [INSTANCE_NAME]
You can also use Cloud Shell to connect your instance from the Cloud Console web UI by using the same command as above. You can connect via the serial console using the Google Cloud Platform Console, the gcloud command-line tool, or a third-party SSH client. The serial console authenticates users with SSH keys. Specifically, you must add your public SSH key to the project or instance metadata, and store your private key on the local machine from which you want to connect. There are other advanced methods to connect to an instance.
I would also recommend to check if you have firewall rule for port 22 which is required for SSH. You can go to the VPC Network from Cloud Console and then Firewall Rules tab, check if you have firewall rule for port 22 and that rule applied to affected instance or not. If there no firewall rule for port 22, create firewall rule and apply to the affected instance.
You can also follow this SSH troubleshooting steps mentioned at this link.
I have the same problem and after recreating 4 instances and going thru every possible ssh key scenario I decided to try chrome and it worked fine whereas in firefox i get the blank black screen after the key handshake. I watched thru the serial port and the sys log showed all of the same entries for my broken web ssh session in firefox as it did for the working chrome web ssh session which means it has to be a problem with firefox.
Same issue. Ad blocker was to blame. Try whitelisting, disabling or use a private window.
