This doesn’t seem like much, if we don’t pay attention. We can see all the steps needed to start sending the data from server to client. The following picture summarizes the initialization of the FTP transfer: This happens in active mode of the data transfer in FTP. Some protocols, like FTP (active/passive mode), send the IP address itself in the data section of the FTP, thus making it very hard to anonymize. But we have to be careful, because some applications were not built with anonymity in mind. We can try to torify the DNS resolution application that we use. Not every application supports SOCKS4a, so this solution doesn’t really solve the problem, because we want a universal solution that works with all applications. The following solutions are available when we want to resolve hostnames securely:
#ANONYMIZER UNIVERSAL VPN REDDIT HOW TO#
But so far, we haven’t yet discussed how to actually configure Tor to resolve hostnames securely. We also discussed why it is important to resolve hostnames securely, so we won’t repeat ourselves: check out part 1if anything is unclear. In the previous Tor article we mentioned the types of SOCKS proxies and certain Tor configuration variables that we can use in the torrc configuration file.
Configuring Tor to Resolve Hostnames Securely So what have we done so far? We’ve configured the web browser to use Burp proxy on port 8080, which in turn uses SOCKS proxy on port 9050, thus successfully being able to complete the proxy chain and browse the Internet anonymously, while still having the advantage of being able to modify requests with Burp.Ģ. If we look at the ports in a LISTENing state again, we can see that port 9050 matches our Tor service:
We can see that we configured Burp to use SOCKS proxy running on host 127.0.0.1 (localhost) on port 9050. We can configure Burp to use SOCKS in the Burp Options under “use SOCKS proxy”. SOCKS is basically a TCP proxy, which can proxy all TCP connections through it, thus not being application specific the application only needs to be capable of tunneling its data through SOCKS proxy. SOCKS proxy works at a lower level than HTTP proxy, thus being able to forward not only HTTP requests. We can see that we set Firefox to route all packets through Burp proxy, running at host 127.0.0.1 on port 8080.Īfterwards we need to configure Burp to use SOCKS proxy, which is started and configured by Tor. The Firefox settings are presented in the picture below: Since the web browser should send all requests to Burp first, we need to configure our web browser to use Burp instead of Privoxy. When Burp is started, we should see the port 8080 open and in LISTEN state:
#ANONYMIZER UNIVERSAL VPN REDDIT INSTALL#
First we have to install and start Burp Suite, which we won’t describe here, since you should already know how to do that, or you wouldn’t be reading this article. Now we have a basic picture how it should all work together, but we still have to configure all of the components to work nicely together. The request is then passed to Tor’s anonymous network (which is already part of the Internet, but we’re representing the Internet in its own node for clarity).
We can see that each request from the web browser first goes into some proxy (in our case Burp), which allows us to do something with it – in most cases all we want to do is to look up the GET/POST parameters and modify them a bit.
