tcpdam | A parking proxy for tcp connections | Proxy library

I want to set proxies to my crawler. I'm using requests module and Beautiful Soup. I have found a list of API links that provide free proxies with 4 types of protocols.

All proxies with 3/4 protocols work (HTTP, SOCKS4, SOCKS5) except one, and thats proxies with HTTPS protocol. This is my code:

I use mitmproxy to gather intel from outbound AS2 (HTTP) requests leaving our network. The schema goes like this:

I am trying to execute an SSIS package using a Credential and Proxy - it works fine with a user with a SysAdmin role and we want to avoid using SysAdmin.

I have followed all the steps to create a Credential and Proxy and set up the permissions for the user in msdb and SSISDb tables and in the Security -> logins

I have followed the steps in the below links as a guide:-

• Run an SSIS Package Under a Different Account
• Running a SSIS Package from SQL Server Agent Using a Proxy Account
• SQL Server Agent - Running SSIS Package with Proxy

Proxy -> properties -> Principals

When I run the job I get the below error - looks like a permission issue

Unable to start execution of step 1 (Reason: Could not get proxy data for proxy_id = 198_. The step failed.

What am I missing?

I am trying to configure a nginx Docker container to serve the Angular application on its root path (which works so far) and make the backend via a proxy on /api available.

I've read multiple threads on Stackoverflow and some blogs, but no configuration worked so far. If I call my app on / the Angular app works. When I try to call /api on the same url it gets redirected to / and shows no content -- I guess the Angular router got some route it cannot handle. But Nginx should catch that route before the Angular app gets called. How do I do that?

I am not sure what is wrong. Do you see the error in my config?

I'm trying to create a reverse proxy to a CONNECT-based HTTP proxy. The user who wants to use the proxy just treats machine A as an HTTP proxy. It works the following way:

1. machine B opens a TCP socket to machine A.
2. On machine A, a TCP socket is exposed on a port and all the incoming data is tunneled to machine B (io.Copy).
3. On machine B, all the data is tunneled to the local HTTP server and the socket to machine A.

Essentially this is a reverse-proxy behind an HTTP proxy. The reason it's this complex is because the HTTP proxy is behind NAT (on machine B) and therefore not accessible directly. The use case is being able to host an HTTP proxy behind a NAT.

Machine A tunnel (Go):

I read that HTTP proxy should be removing hop HTTP headers (https://www.freesoft.org/CIE/RFC/2068/143.htm)

It makes sense since some of these headers are connection-related.

The question is. Is this RFC applicable for explicit proxy only or should be it be done on transparent HTTP proxies too?

Just to give you an example. Let say a client does HTTP call and it has an explicit proxy set. However, there is a transparent proxy in the middle. So, the overall pipeline looks like that

I've been looking around trying to find a solution, but nothing has worked. I have this code:

I have video files hosted on the CDN, the video file is encrypted. So I need the decrypt it before play it in the browser. But the web video tag has no interface to modify the media stream.

So I want to run a proxy in the client side with javascript to proxy the media stream request, and decrypt the stream before feet to the video tag.

Is it possible?

By math-chen's answer, I have tryed below code, but when I paly it, the video keep spin and not render the frame like below image.

I use a very small unencrypted video file out.mp4, so it can be loaded by once.

It has been discussed many times on Stackoverflow that by default WebRTC technology leaks your real IP even if your using a proxy to browse the web. What I haven't seen discussed is whether this requires the end user to click a button to enable this kind of leak or whether the leak occurs regardless of any action taken by the user.

For example, when you go to Express VPN they require you press a button to test for WebRTC leak. My question is - is this done for privacy reasons or somehow the button activates WebRTC tech so it can leak your IP?

In other words, assuming you never need to use WebRTC tech (just browser a blog or eCommerce shop) and all you do is click a few links - can a website still detect your real IP through WebRTC?

Thanks
