Questions[tinyproxy](server)

I installed tinyproxy 1.8.4 on a bastion host with public IP on GCP, to forward traffic to a private GKE cluster. Now I'm using ssh to connect to the bastion host with port forwarding and the connection is established correctly, however, Running local commands for example HTTPS_PROXY=localhost:8888 kubectl get pods --all-namespaces returns this error Unable to connect to the server: Access denied.

I also tried the same command from inside the bastion host but got the same issue.

In the log file of tinyproxy I find these entries each time I try to execute the previous command. These are the logs of tinyproxy.

I'm following this guide https://github.com/GoogleCloudPlatform/gke-private-cluster-demo and I don't know where is the issue. Thank you in advance.

I have tinyproxy installed on localhost (I also tried squid and failed similarly). It runs on port 8888. This works:

curl -x localhost:8888 http://www.google.com

And I see output in the tinyproxy logs.

Now I run the latest version of ngrok and get the following forwarding established:

http://<identifier>.ngrok.io -> localhost:8888

If I open http://<identifier>.ngrok.io on my browser the ngrok connection counter goes up, and I successfully see tinyproxy's "not implemented" error page.

However, this fails:

curl -x <identifier>.ngrok.io:80 http://www.google.com
# => curl: (56) Received HTTP code 404 from proxy after CONNECT

The ngrok counter does not go up, and I do not see messages in the tinyproxy logs, suggesting that the failure is before ngrok accepted the connection.

What am I missing here? I had assumed that both ngrok and tinyproxy forward the HTTP request, but it seems like there might be another protocol operating behind the scenes of curl -x. Is there a way to successfully establish the proxy chain starting at ngrok and going through my localhost?

I want to create a Vagrant dev environment where a dev would be able to hit dev.example.com and the vagrant machine would make the same request to staging.example.com except filter out some files, say app.js and main.css and serve those from local fs.

There are too many api dependancies reeking havoc for smooth local development.

This is possible? Any tips or suggestions would also be helpful as well

I am confused as to how to set up username/password restrictions on tinyproxy (so that not all the world can access it - ip alow/block has limited use in my setup). Any pointers?

Thank you!

I'm trying to serve some pages via TinyProxy.

When I change my Firefox proxy settings to:

localhost:8888 (yes, I'm using a tunnel), all I get is a white screen?

When I comment out the line:

Listen x.x.x.x (the address of my server)

I get a 403 error:

Access denied

The administrator of this proxy has not configured it to service requests from your host.
Generated by tinyproxy version 1.8.1.

At least I'm sure my tunnelling is working when I get this error...

However, can someone please help me with the configuration of TinyProxy?

Many thanks in advance,
