Is port 5167 dangerous?

We have no specific security note for port 5167. 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 5167, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5167'      # process listening on 5167
sudo lsof -nP -i :5167

macOS

sudo lsof -nP -i :5167

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5167 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5167
netstat -ano | findstr :5167

From another machine

nmap -p 5167 -sV <host>
sudo nmap -sU -p 5167 <host>
nc -zv <host> 5167

Block it in the firewall

sudo ufw deny 5167/tcp                                         # Linux (ufw)

What is port 5167 used for?

Port 5167 is assigned by IANA to scte104 (SCTE104 Connection).

Is port 5167 TCP or UDP?

Port 5167 is registered for TCP and UDP.

Is it safe to open port 5167?

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 5167 is open?

On Linux run "ss -ltnup 'sport = :5167'", on macOS "lsof -nP -i :5167", and on Windows "netstat -ano | findstr :5167" to see the local process. From another machine, "nmap -p 5167 <host>" shows whether it is reachable.
