  • 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 7624, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7624'      # process listening on 7624
sudo lsof -nP -i :7624

macOS

sudo lsof -nP -i :7624

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7624 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7624
netstat -ano | findstr :7624

From another machine

nmap -p 7624 -sV <host>
sudo nmap -sU -p 7624 <host>
nc -zv <host> 7624

Block it in the firewall

sudo ufw deny 7624/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7624" -Direction Inbound -LocalPort 7624 -Protocol TCP -Action Block  # Windows

Port 7624 is assigned by IANA to indi (Instrument Neutral Distributed Interface).

Is port 7624 TCP or UDP?

Port 7624 is registered for TCP and UDP.

Is it safe to open port 7624?

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 7624 is open?

On Linux run "ss -ltnup 'sport = :7624'", on macOS "lsof -nP -i :7624", and on Windows "netstat -ano | findstr :7624" to see the local process. From another machine, "nmap -p 7624 <host>" shows whether it is reachable.
