Nmap udp port scanning

I have udp ports open on remote system. But still it is showing open | filtered using nmap.I can’t see any open udp ports on nmap .Please give me solution for this.Is there any other tool to verify that.

Welcome @ruchi,

  1. Login to your remote system
  2. As root user run the following to list all open tcp/udp port (filtered to udp using the grep command):
    ss -tulpn | grep udp
    netstat -tulpn | grep udp
  3. Post output here if you still have doubt.

Thanks for the reply. but I know the open udp ports and that can be seen from remote host.But I want to see that in my system .So how can I do that with some other tools or using nmap in kali Linux
