01 Security

Is port 6316 dangerous?

We have no specific security note for port 6316. 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 6316, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6316'      # process listening on 6316
sudo lsof -nP -i :6316

macOS

sudo lsof -nP -i :6316

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6316 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6316
netstat -ano | findstr :6316

From another machine

nmap -p 6316 -sV <host>
sudo nmap -sU -p 6316 <host>
nc -zv <host> 6316

Block it in the firewall

sudo ufw deny 6316/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 6316" -Direction Inbound -LocalPort 6316 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 6316 used for?

Port 6316 is assigned by IANA to abb-escp (Ethernet Sensor Communications Protocol).

Is port 6316 TCP or UDP?

Port 6316 is registered for TCP and UDP.

Is it safe to open port 6316?

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 6316 is open?

On Linux run "ss -ltnup 'sport = :6316'", on macOS "lsof -nP -i :6316", and on Windows "netstat -ano | findstr :6316" to see the local process. From another machine, "nmap -p 6316 <host>" shows whether it is reachable.
