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

nmap -sV 10.9.0.136 -A

it shows :

Starting Nmap 7.40 ( https://nmap.org ) at 2017-04-25 11:30 IST
Nmap scan report for 10.9.0.136
Host is up (0.00013s latency).
All 1000 scanned ports on 10.9.0.136 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?

gufw rule

  • First, try with command nmap 10.9.0.136 -P0 and give me output. Also give me output from firewall rules sudo ufw status – 2707974 Apr 25 '17 at 6:19

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