01 Security

Is port 10010 dangerous?

We have no specific security note for port 10010. 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 10010, and is it reachable?

Linux

sudo ss -ltnup 'sport = :10010'      # process listening on 10010
sudo lsof -nP -i :10010

macOS

sudo lsof -nP -i :10010

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 10010 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 10010
netstat -ano | findstr :10010

From another machine

nmap -p 10010 -sV <host>
nc -zv <host> 10010

Block it in the firewall

sudo ufw deny 10010/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 10010" -Direction Inbound -LocalPort 10010 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 10010 used for?

Port 10010 is assigned by IANA to rxapi (ooRexx rxapi services).

Is port 10010 TCP or UDP?

Port 10010 is registered for TCP.

Is it safe to open port 10010?

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 10010 is open?

On Linux run "ss -ltnup 'sport = :10010'", on macOS "lsof -nP -i :10010", and on Windows "netstat -ano | findstr :10010" to see the local process. From another machine, "nmap -p 10010 <host>" shows whether it is reachable.
