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?
