proxychains VS streisand

Fun fact: proxychains uses LD_PRELOAD [0] to hook the necessary syscalls [1] for setting up a "proxy environment" for the wrapped program, e.g. `connect`, `gethostbyname`, `gethostbyaddr`, etc. Note this also implies that it could be leaky in some cases when applied to a program that uses alternative syscalls to make an external connection.

You can use ProxyChains in order to use the SOCKS5 proxy with any application, depending on the OS you are using.

I assume that https://github.com/haad/proxychains is the project in question. At https://github.com/haad/proxychains/blob/master/src/proxychains.conf you can view the contents of the configuration file and then save it in /etc/proxychains.conf.

That is weird. However, missing configs are usually an easy problem to solve - simply find one online and copy it (once you understand it). Here is the one from the proxy chains repo. Lastly, be careful with Kali, it's definitely not suited to beginners (you're doing the right thing running it in a VM at least).

ntlmrelayx2proxychains aims to connect the tool of the SecureAuthCorps' impacket suite, ntlmrelayx.py (hereafter referred to as "ntlmrelayx"), along with @byt3bl33d3r's tool, CrackMapExec (hereafter referred to as "CME"), over proxychains, developped by haad.

You can go even further with tools like proxychains that let you chain multiple proxies. This is used while setting up tor and comes pre-installed with pentesting distros like Kali and ParrotOS.

Streisand sets up a new server running your choice of WireGuard, OpenConnect, OpenSSH, OpenVPN, Shadowsocks, sslh, Stunnel, or a Tor bridge. It also generates custom instructions for all of these services. At the end of the run you are given an HTML file with instructions that can be shared with friends, family members, and fellow activists.

Unfortunately, that's to the Great Firewall of China, there has been a lot of resources put in to fingerprint VPNs and block them by state actors.

Fortunately, however, there is equally years of some of the smartest minds on the planet working to bypass Chinese censorship, so there are some great OpenVPN alternatives.

I really encourage you to look into something like Shadowsocks which Chinese people have found great success in using over the last several years.

It's quite sad that projects like Streisand[0] were archived, but I'm sure there are other alternatives that might make it just as easy to roll onto a server.

The Streisand Project[0] provided easy installation of well-configured certs, VPNs and various other software on cloud instances. It was great for travelling internationally: run the script and after a few minutes one had a cloud instance and everything one needed to securely access the Internet through one’s own country.

Unfortunately, it was archived in 2021. Is there anything in 2023 which approaches it? I’ve seen Algo[1], but I don’t believe it does as much to help one to avoid packet filtering. It’s also based on Ubuntu rather than Debian, which seems like a mistake with security-conscious server software.

It basically works like any normal VPN. Setting it up is quite easy, you just need a VPS and setup Streisand by following their guide.

You are better off renting a cloud server and rolling your own, e.g. using Streisand, Algo or my own Edgewalker

I currently use https://github.com/StreisandEffect/streisand which was extremely simple to set up.

What are the main advantages over Streisand?

For a VPN, I use Streisand (https://github.com/StreisandEffect/streisand) running on a box in a datacenter in Iceland. I also occasionally use other VPNs. I turn off the VPN on my gaming PC when playing specific games.
