I've added a SSH rule for adding 4444 port in my distro through gufw but when I run

nmap -sV -A

it shows :

Starting Nmap 7.40 ( https://nmap.org ) at 2017-04-25 11:30 IST
Nmap scan report for
Host is up (0.00013s latency).
All 1000 scanned ports on are closed
Too many fingerprints match this host to give specific OS details
Network Distance: 0 hops
OS and Service detection performed. Please report any incorrect results at https://nmap.org/submit/ .
Nmap done: 1 IP address (1 host up) scanned in 3.50 seconds

What am I doing wrong?

    Are you sure that service listen for connection on port 4444. Do you see service in listening state in output from command netstat -atpn? – 2707974 Apr 25 '17 at 6:51

"By default, Nmap scans the most common 1,000 ports for each protocol. "

Try to specify -p4444

  • Nmap scan report for Host is up (0.00012s latency). PORT STATE SERVICE 4444/tcp closed krb524 – Random Raita Apr 25 '17 at 6:39
