I keep seeing repeated attempts to access my system from an IP originating from Romania, can anyone tell me how to block it?

Why/how is your unRAID server exposed with a public IP?

 

 

Having your server wide open to the internet is not a good idea. Put a firewall in front of it that will give you the ability to allow/deny specific IP traffic. Stock unraid does not have firewall capabilities.

I have ssh open and another for SABNzbd while testing it.  I'm not overly concerned about, I'm just annoyed by it.

 

I wasn't home btw, and didn't have access to my firewall.  Anyways I've changed the port for now, and added a line to my hosts.deny file.  Thanks for the help.
