01 Security

Is port 5450 dangerous?

We have no specific security note for port 5450. 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 5450, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5450'      # process listening on 5450
sudo lsof -nP -i :5450

macOS

sudo lsof -nP -i :5450

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5450 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5450
netstat -ano | findstr :5450

From another machine

nmap -p 5450 -sV <host>
sudo nmap -sU -p 5450 <host>
nc -zv <host> 5450

Block it in the firewall

sudo ufw deny 5450/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5450" -Direction Inbound -LocalPort 5450 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5450 used for?

Port 5450 is assigned by IANA to tiepie (TiePie engineering data acquisition), tiepie-disc (TiePie engineering data acquisition (discovery)).

Is port 5450 TCP or UDP?

Port 5450 is registered for TCP and UDP.

Is it safe to open port 5450?

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 5450 is open?

On Linux run "ss -ltnup 'sport = :5450'", on macOS "lsof -nP -i :5450", and on Windows "netstat -ano | findstr :5450" to see the local process. From another machine, "nmap -p 5450 <host>" shows whether it is reachable.
