Use nmap to find machines and open ports

In the evening I used nmap to find all machines on my local network, with success. I used:

nmap -sn 192.168.11.0/24

I also used the following command to find all open ports on my Mac Mini:

sudo nmap -p 1-65535 -sV \
     -sS -T4 ip-address

This scan took 1804.45 seconds.

The following open ports where found:

  • 88/tcp Heimdal Kerberos
  • 5900/tcp Apple remote desktop vnc
  • 63946/tcp unknown
  • 63947/tcp unknown

According to the admin subnet TCP/UDP port finder both are related to Xsan Filesystem Access (Apple). See also TCP and UDP ports used by Apple software products.
