01 Security

Is port 10110 dangerous?

We have no specific security note for port 10110. Its risk depends on the program actually listening on it. General advice for other services services:

  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 10110, and is it reachable?

Linux

sudo ss -ltnup 'sport = :10110'      # process listening on 10110
sudo lsof -nP -i :10110

macOS

sudo lsof -nP -i :10110

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 10110 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 10110
netstat -ano | findstr :10110

From another machine

nmap -p 10110 -sV <host>
sudo nmap -sU -p 10110 <host>
nc -zv <host> 10110

Block it in the firewall

sudo ufw deny 10110/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 10110" -Direction Inbound -LocalPort 10110 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 10110 used for?

Port 10110 is assigned by IANA to nmea-0183 (NMEA-0183 Navigational Data).

Is port 10110 TCP or UDP?

Port 10110 is registered for TCP and UDP.

Is it safe to open port 10110?

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. Close the port if nothing on the host needs it.

How do I check if port 10110 is open?

On Linux run "ss -ltnup 'sport = :10110'", on macOS "lsof -nP -i :10110", and on Windows "netstat -ano | findstr :10110" to see the local process. From another machine, "nmap -p 10110 <host>" shows whether it is reachable.
