Is port 10081 dangerous?

We have no specific security note for port 10081. 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 10081, and is it reachable?

Linux

sudo ss -ltnup 'sport = :10081'      # process listening on 10081
sudo lsof -nP -i :10081

macOS

sudo lsof -nP -i :10081

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 10081 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 10081
netstat -ano | findstr :10081

From another machine

nmap -p 10081 -sV <host>
sudo nmap -sU -p 10081 <host>
nc -zv <host> 10081

Block it in the firewall

sudo ufw deny 10081/tcp                                         # Linux (ufw)

04 FAQ
What is port 10081 used for?

Port 10081 is assigned by IANA to famdc (FAM Archive Server).

Is port 10081 TCP or UDP?

Port 10081 is registered for TCP and UDP.

Is it safe to open port 10081?

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 10081 is open?

On Linux run "ss -ltnup 'sport = :10081'", on macOS "lsof -nP -i :10081", and on Windows "netstat -ano | findstr :10081" to see the local process. From another machine, "nmap -p 10081 <host>" shows whether it is reachable.
