01 Security

Is port 5014 dangerous?

We have no specific security note for port 5014. 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 5014, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5014'      # process listening on 5014
sudo lsof -nP -i :5014

macOS

sudo lsof -nP -i :5014

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5014 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5014
netstat -ano | findstr :5014

From another machine

nmap -p 5014 -sV <host>
sudo nmap -sU -p 5014 <host>
nc -zv <host> 5014

Block it in the firewall

sudo ufw deny 5014/udp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5014" -Direction Inbound -LocalPort 5014 -Protocol UDP -Action Block  # Windows
04 FAQ
What is port 5014 used for?

Port 5014 is assigned by IANA to onpsocket (Overlay Network Protocol).

Is port 5014 TCP or UDP?

Port 5014 is registered for UDP.

Is it safe to open port 5014?

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 5014 is open?

On Linux run "ss -ltnup 'sport = :5014'", on macOS "lsof -nP -i :5014", and on Windows "netstat -ano | findstr :5014" to see the local process. From another machine, "nmap -p 5014 <host>" shows whether it is reachable.
