Attention

If you run a port scanner, my server is going to attempt to connect to your host. That's how a port scanner works. My server is not trying to hack you. Please don't contact us or our datacenter, complaining that you are getting hacked. Instead, read a book on how the TCP/IP protocol works, and understand your own actions.
