01 Security

Is port 5168 dangerous?

We have no specific security note for port 5168. 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 5168, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5168'      # process listening on 5168
sudo lsof -nP -i :5168

macOS

sudo lsof -nP -i :5168

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5168 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5168
netstat -ano | findstr :5168

From another machine

nmap -p 5168 -sV <host>
sudo nmap -sU -p 5168 <host>
nc -zv <host> 5168

Block it in the firewall

sudo ufw deny 5168/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5168" -Direction Inbound -LocalPort 5168 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5168 used for?

Port 5168 is assigned by IANA to scte30 (SCTE30 Connection).

Is port 5168 TCP or UDP?

Port 5168 is registered for TCP and UDP.

Is it safe to open port 5168?

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 5168 is open?

On Linux run "ss -ltnup 'sport = :5168'", on macOS "lsof -nP -i :5168", and on Windows "netstat -ano | findstr :5168" to see the local process. From another machine, "nmap -p 5168 <host>" shows whether it is reachable.
