I received a email from charter saying someone was running a port scanner on my network. That is against there tos and I needed to update my antivirus and so on.
I am running ubuntu and not sure how to make sure its not running a port scanner. Called charter security team they weren't very helpful. They are threatening termination of service if its not fixed. Yet they cant tell me how to fix it. Can someone help me figure out what is going on.
