01 Security

Is port 10810 dangerous?

We have no specific security note for port 10810. Its risk depends on the program actually listening on it. General advice for network services services:

  • Answer only the networks that need the service (no open resolvers, relays or reflectors).
  • UDP services can be abused for DDoS amplification: rate-limit or block them at the edge.
  • Disable legacy test services that have no use in production.

03 Check it

Which program uses port 10810, and is it reachable?

Linux

sudo ss -ltnup 'sport = :10810'      # process listening on 10810
sudo lsof -nP -i :10810

macOS

sudo lsof -nP -i :10810

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 10810 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 10810
netstat -ano | findstr :10810

From another machine

nmap -p 10810 -sV <host>
sudo nmap -sU -p 10810 <host>
nc -zv <host> 10810

Block it in the firewall

sudo ufw deny 10810/udp                                         # Linux (ufw)

04 FAQ
What is port 10810 used for?

Port 10810 is assigned by IANA to nmc-disc (Nuance Mobile Care Discovery).

Is port 10810 TCP or UDP?

Port 10810 is registered for UDP.

Is it safe to open port 10810?

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Answer only the networks that need the service (no open resolvers, relays or reflectors).

How do I check if port 10810 is open?

On Linux run "ss -ltnup 'sport = :10810'", on macOS "lsof -nP -i :10810", and on Windows "netstat -ano | findstr :10810" to see the local process. From another machine, "nmap -p 10810 <host>" shows whether it is reachable.
