Is port 5416 dangerous?

We have no specific security note for port 5416. 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 5416, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5416'      # process listening on 5416
sudo lsof -nP -i :5416

macOS

sudo lsof -nP -i :5416

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5416 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5416
netstat -ano | findstr :5416

From another machine

nmap -p 5416 -sV <host>
sudo nmap -sU -p 5416 <host>
nc -zv <host> 5416

Block it in the firewall

sudo ufw deny 5416/tcp                                         # Linux (ufw)

04 FAQ
What is port 5416 used for?

Port 5416 is assigned by IANA to sns-gateway (SNS Gateway).

Is port 5416 TCP or UDP?

Port 5416 is registered for TCP and UDP.

Is it safe to open port 5416?

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 5416 is open?

On Linux run "ss -ltnup 'sport = :5416'", on macOS "lsof -nP -i :5416", and on Windows "netstat -ano | findstr :5416" to see the local process. From another machine, "nmap -p 5416 <host>" shows whether it is reachable.
