01 Security

Is port 2382 dangerous?

We have no specific security note for port 2382. 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 2382, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2382'      # process listening on 2382
sudo lsof -nP -i :2382

macOS

sudo lsof -nP -i :2382

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2382 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2382
netstat -ano | findstr :2382

From another machine

nmap -p 2382 -sV <host>
sudo nmap -sU -p 2382 <host>
nc -zv <host> 2382

Block it in the firewall

sudo ufw deny 2382/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2382" -Direction Inbound -LocalPort 2382 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2382 used for?

Port 2382 is assigned by IANA to ms-olap3 (Microsoft OLAP).

Is port 2382 TCP or UDP?

Port 2382 is registered for TCP and UDP.

Is it safe to open port 2382?

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 2382 is open?

On Linux run "ss -ltnup 'sport = :2382'", on macOS "lsof -nP -i :2382", and on Windows "netstat -ano | findstr :2382" to see the local process. From another machine, "nmap -p 2382 <host>" shows whether it is reachable.
