Server - Handshake phase does not handle packet 3 (fd 19)

[Beforekk 82]

Hello,

so in last few weeks, Im investigating why is my Core dropping with syserr Analyze: HANDSHAKE phase does not handle packet 3 (fd 19)

Yestrday Ive added this "Track this syserr" by @ WeedHex and it was more then helpful, so thanks!

Because today my core crashed again with IP... So I looked at it a little bit and find this: 

Its from Belize FlyServers S.A. datacenter - So I searched info about it

and got this:

 

Fraud Score
IP Reputation99 - High Risk

Mail SPAM Block List IP Reported as Blacklisted

Proxy/VPN Detection Proxy/VPN Detected
This IP address appears to be a high risk proxy connection.

 

 

And what is my question?

What should I do, to prevent this? First of all, I havent installed any protection yet. 

Thanks for any help

I heard many people receiving handshake from Belize location >_< 

However I don't think your core crash is related to that syserr.

Analyze with #dbg your core crash first of all.

 

About handshake you can decide to blacklist the intrusive ip.

Activate a firewall leaving public only the needed ports, and put some limit or check.

Yea, you're right. It was very big coincidence of errors, that it seemed to be the reason of core crashing. But its not.

Still thanks for reply

Nope. All I did was firewall and block those IP, but I finds out, that handshakes are coming from diferent IPs
