Maybe your ISP uses cg-nat and you can ask them to opt-out or find and ISP with this option.

Nope, it is the same. Bittorrent have a lot more users than eMule and then you have more possibilities to find a peer with ports forwarded. 2 peers Without port forwarded can not share content.

The problem with HighID/LowID on eMule is the same on bittorrent or any other p2p, you need someone with port forwarding to upload/download content. In my case I am out of cg-nat and sharing 24/7.

Ed2k/kad network still have good health with new and old stuff

Well usually FHD, good availability of recent and old stuff, there is a good community of French, Italian and Spanish stuff with English sub. Probably if you prefer 4k and above, torrent is better.

My main use is movies, shows and books. And it is perfectly fine.

Mldonkey have been updated on August 2024 and it is available on gnu/linux, mac and windows.

Ed2k/kad are still kicking, I use mldonkey for that networks

mldonkey for ed2k/kad network and bittorrent

Headless server with debian and mldonkey, I search on ed2k/kad network and public trackers for bittorrent. I use plex to stream to my devices.

Perfectly alive with aprox 100k daily users

I compile the source code: git clone, cd mldonkey, ./configure, make, make install

Removed by mod

You still have realvnc lite. It is free, 1 user, 3 machines, less features, but the basics still there.

You could use i2p for torrent it is free and secure, but slow

Well you could run these services in your server (only if you have enough spare bandwidth, ram and cpu) to help the comunity to circumvent censorship in some countries, like Russia or Iran. Here you have more information for tor and i2pd.

Tor relay (guard/middle or bridge/snowflake) and i2p node (i2p, i2p+ or i2pd)

You could try on ed2k/kad network (emule/amule/mldonkey)

This is the MINIMUM: OS: Ubuntu 20.04 Processor: 4 hardware CPU threads - Intel® Core™ i5 750 or higher Memory: 8 GB RAM Graphics: AMD GCN+ or NVIDIA Kepler+ with up-to-date Vulkan drivers. Support for VK_EXT_graphics_pipeline_library highly recommended. Storage: 85 GB available space Sound Card: Highly recommended

You should try with your CPU and GPU

I know you are asking for cs 1.6, but do you know counter strike 2 is free on steam and have compatibility with Linux?
