Hi Spigot, I first want to thank the Spigot team for Netty support. It has eliminated so many network issues. But one still remains. As you may know, there is a Ddos type called "R-U-Dead-Yet" witch is classified as Layer 7. My server has been under attack with the so called technique for 5 days. I looked everywhere on the net, did all the research I could but couldn't find anything. The only thing I found that the attack is called RUDY. So I am HOPELESS and need your HELP, PLEASE System properties: Linux Centos 6.3 Spigot RB #617 (with snapshot-protocol) With or without plugins, same issue This is what shows up in the logs: Protocol error: Code (Text): [INFO] Disconnecting /220.127.116.11:47382: Protocol error [INFO] Disconnecting /18.104.22.168:47382: Protocol error [INFO] Disconnecting /22.214.171.124:47382: Protocol error [INFO] Disconnecting /126.96.36.199:47382: Protocol error [INFO] Disconnecting /188.8.131.52:47382: Protocol error (this repeats over 100 times per milisecond, ip changes every minute) Bots: Code (Text): [INFO] Disconnecting RIQTQPCHCXIH [/184.108.40.206:2063]: Outdated client!

Help! So, If anyone has had a similar issue and found a way to figure it out, please help me too. I could really use suggestions about hosting companies witch provide protections to this sort of attacks. I have a budget of 150$/month and I have around 250 online, so the price is important. Any other plugin or software suggestions for linux would be very very appreciated. Please Spigot, don't let some problematic guys take down my server for ever THANK YOU!
