I've run nmap -sS [computer ip] and see that i only have one service running:

4000/tcp open  remoteanything

What service is this? Should i close it? I've googled and only found some shady stuff: http://remote-anything.com/ Maybe it is used by some of my other programs?

nmap just makes a guess at the service here, as basically any application can bind to any port. To see which specific application it is in your case, run

lsof -i :4000
  • Thanks! Got this: COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME thnuclnt 63892 USER 3u IPv4 0x579547807ed98faf 0t0 TCP *:terabase (LISTEN) Googled it and it is most likely used by VMWare, thank you!
