01 Security

Is port 3019 dangerous?

We have no specific security note for port 3019. 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 3019, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3019'      # process listening on 3019
sudo lsof -nP -i :3019

macOS

sudo lsof -nP -i :3019

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3019 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3019
netstat -ano | findstr :3019

From another machine

nmap -p 3019 -sV <host>
sudo nmap -sU -p 3019 <host>
nc -zv <host> 3019

Block it in the firewall

sudo ufw deny 3019/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3019" -Direction Inbound -LocalPort 3019 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3019 used for?

Port 3019 is assigned by IANA to resource_mgr (Resource Manager), resource-mgr (Resource Manager IANA assigned this well-formed service name as a replacement for "resource_mgr".).

Is port 3019 TCP or UDP?

Port 3019 is registered for TCP and UDP.

Is it safe to open port 3019?

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 3019 is open?

On Linux run "ss -ltnup 'sport = :3019'", on macOS "lsof -nP -i :3019", and on Windows "netstat -ano | findstr :3019" to see the local process. From another machine, "nmap -p 3019 <host>" shows whether it is reachable.
