Instead of searching for a sketchy "KY-888" executable file online, your best and safest bet is to download the official, generic drivers directly from Realtek. Step-by-Step: How to Download the Official Drivers Safely
KY‑888’s connector glowed faintly. He translated USB’s packet-tunnel into Ethernet frames, translating the old language of legacy hardware into the modern tongue the network understood. The switch blinked in reply, and a steady stream of bits began to flow. Mira exhaled, cheeks wet from rain and tears of relief, as her slides began to upload.

Creating an account allows you to register your server(s). Once a server is associated with your account and validated you can start sharing your bans with the community as well as purchasing a 24/7 Rustadmin Online instance. The Rustadmin bans sharing system is very powerful to fight against cheaters and toxic players. When a player is banned from a server and the admin decides to share his ban then anybody else having this player on his server is able to see how many times he got banned from other servers and why.

I've created Rustadmin in 2014 for my own usage and started to release it in 2015. I had no idea at this point that it would become such a widely used RCON tool and I have been amazed by people I met through this program. Thank you everyone for your support and your kindness, working with server admins is a real pleasure and I'm happy to help people managing their servers.
I don't play Rust anymore (since 2017) but I do still maintain Rustadmin and try to implement the majority of all your requested features.
