01 Security

Is port 5047 dangerous?

We have no specific security note for port 5047. 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 5047, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5047'      # process listening on 5047
sudo lsof -nP -i :5047

macOS

sudo lsof -nP -i :5047

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5047 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5047
netstat -ano | findstr :5047

From another machine

nmap -p 5047 -sV <host>
sudo nmap -sU -p 5047 <host>
nc -zv <host> 5047

Block it in the firewall

sudo ufw deny 5047/udp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5047" -Direction Inbound -LocalPort 5047 -Protocol UDP -Action Block  # Windows
04 FAQ
What is port 5047 used for?

Port 5047 is assigned by IANA to iscape (iSCAPE Data Broadcasting).

Is port 5047 TCP or UDP?

Port 5047 is registered for UDP.

Is it safe to open port 5047?

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 5047 is open?

On Linux run "ss -ltnup 'sport = :5047'", on macOS "lsof -nP -i :5047", and on Windows "netstat -ano | findstr :5047" to see the local process. From another machine, "nmap -p 5047 <host>" shows whether it is reachable.
