01 Security

Is port 3002 dangerous?

We have no specific security note for port 3002. 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 3002, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3002'      # process listening on 3002
sudo lsof -nP -i :3002

macOS

sudo lsof -nP -i :3002

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3002 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3002
netstat -ano | findstr :3002

From another machine

nmap -p 3002 -sV <host>
sudo nmap -sU -p 3002 <host>
nc -zv <host> 3002

Block it in the firewall

sudo ufw deny 3002/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3002" -Direction Inbound -LocalPort 3002 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3002 used for?

Port 3002 is assigned by IANA to exlm-agent (EXLM Agent), remoteware-srv (RemoteWare Server).

Is port 3002 TCP or UDP?

Port 3002 is registered for TCP and UDP.

Is it safe to open port 3002?

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 3002 is open?

On Linux run "ss -ltnup 'sport = :3002'", on macOS "lsof -nP -i :3002", and on Windows "netstat -ano | findstr :3002" to see the local process. From another machine, "nmap -p 3002 <host>" shows whether it is reachable.
