01 Security

Is port 9010 dangerous?

We have no specific security note for port 9010. 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 9010, and is it reachable?

Linux

sudo ss -ltnup 'sport = :9010'      # process listening on 9010
sudo lsof -nP -i :9010

macOS

sudo lsof -nP -i :9010

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 9010 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 9010
netstat -ano | findstr :9010

From another machine

nmap -p 9010 -sV <host>
nc -zv <host> 9010

Block it in the firewall

sudo ufw deny 9010/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 9010" -Direction Inbound -LocalPort 9010 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 9010 used for?

Port 9010 is assigned by IANA to sdr (Secure Data Replicator Protocol).

Is port 9010 TCP or UDP?

Port 9010 is registered for TCP.

Is it safe to open port 9010?

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 9010 is open?

On Linux run "ss -ltnup 'sport = :9010'", on macOS "lsof -nP -i :9010", and on Windows "netstat -ano | findstr :9010" to see the local process. From another machine, "nmap -p 9010 <host>" shows whether it is reachable.
