From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

back when I used ubuntu derivatives I used privoxy and edited the config file to route all my traffic through tor.

I just did the same on debian 12.6 and wonder if there's a better alternative.

I don't use tor that often but as my understanding tor is basically a socks5 proxy, which operates at application layer, so there is no way you can route all your traffic through tor, at least not the ICMP packets.

Some applications are willing to use your proxy settings like http_proxy and https_proxy environment variables, but some of them not, especially for udp based applications (most games). The workaround that i am aware of is to use a rule-based proxy program that supports TUN mode, such as Clash Meta (the link is a fork of clash meta called mihomo, which is the one that i am currently using). Basically it creates a virtual interface and traps all the higher layer traffic into this interface, so it can route them through the configured proxy (tor in your case), even for applications that don't honor your proxy settings at all.

In Clash Meta you can use configurations such as this to route all your layer 5 and 4 traffic through tor, the important part is to enable the tun mode. After that you can simply use command mihomo -f config.yaml to start it.
