Most of the portscan websites that I've looked into use nmap > under the covers. OK, done. But man nmap is completely incomprehensible to me. I know pings are blocked so I need -Pn. When I do nmap -Pn myhost I get 998 filtered ports 22/tcp closed 50001 open I could move my ftp and http stuff to the cloud computer. That leaves ssh as the only essential service. If assume 22 and 22xx are blocked, could I use 50001 as my ssh port?
