Nmap_slow_comprehensive_scan show list of unknown udp ports
 

While doing nmap slow comprehensive scan to device a list of unkonw upd ports are shown as follow

Why would these UDP Ports be open?
Zenmap found these open.

17077/udp open|filtered unknown
17459/udp open|filtered unknown
19632/udp open|filtered unknown
19647/udp open|filtered unknown
21320/udp open|filtered unknown
21524/udp open|filtered unknown
22341/udp open|filtered unknown
36384/udp open|filtered unknown
38412/udp open|filtered unknown

Please can any one explain regarding the same.

Thanks

Hi,

You can run:
to find what uses these ports

Hi bathory,

I can't find any above mentioned port through the command "netstat -anpul", but still they are showing under nmap slow scna.

Thanks
Pavan

You should run it as root, or else you won't get the process name
You can also use the lsof command (as root):

Yes, I am running that command in root itself, and I have found that the ports which are shown in nmap scna are not listed in tc/udp ports, please find in the following link "http://en.wikipedia.org/wiki/List_of...P_port_numbers"

They are not listed, because they are not standard ports.
You can find the standard ports and their associated services in /etc/services.

Thanks bathory, just I want to confirm one thing, when ever I am doing nmap scan to my device IP, the scan o/p is showing list of of unknow ports as mentioned above, so is that a problem with my device or it is bug???

It's not a bug or a problem per se, but perhaps you should use the commands above, in order to investigate further what services are running on these ports.

Thanks a lot......:)
