To find out which ports are open on the server use the following NMAP command:
sudo nmap 10.10.21.231 -p- -Pn -n --disable-arp-ping -vv
|-p-||Scan all available ports (65535)|
|-Pn||Disables ICMP Echo Requests|
|-n||Disables DNS Resolution|
|–disable-arp-ping||Disables ARP Ping Requests|
Note that when you use the timing template e.g. -T4 option you may not see all the open ports.
