What exactly are you curious about, crysx?

You'll find some details in my blog post from a few years ago:  https://da-data.blogspot.com/2014/03/blockchain-explorations-riecoin-miner.html

Also, for others interested:  I've now set up a Riecoin node on a server that's behind a PureVPN DDoS-protected connection:  https://www.purevpn.com/blog/ddos-protected-vpn-purevpn/

and it seems to be working uninterrupted.  I'd recommend.  A normal VPN won't do it - the jerk was able to take out my first two attempts - but this one seems robust enough.  One might suspect that if enough of us set up DDoS-protected Riecoin nodes, then attacking the network may become pointless.  I think it was $70/year for this one.  Cheap enough for stopping a jerk.

Gatra, do you know about Cloudflare?  At minimum, it would probably be a good try to move the riecoin website behind it.  You let them run the DNS for you and then put your server online on some IP only you know.  It's a very good first start.  It's also free.   And very easy to use.
