01 Security

Is port 2624 dangerous?

We have no specific security note for port 2624. 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 2624, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2624'      # process listening on 2624
sudo lsof -nP -i :2624

macOS

sudo lsof -nP -i :2624

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2624 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2624
netstat -ano | findstr :2624

From another machine

nmap -p 2624 -sV <host>
sudo nmap -sU -p 2624 <host>
nc -zv <host> 2624

Block it in the firewall

sudo ufw deny 2624/tcp                                         # Linux (ufw)

What is port 2624 used for?

Port 2624 is assigned by IANA to aria (Aria).

Is port 2624 TCP or UDP?

Port 2624 is registered for TCP and UDP.

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 2624 is open?

On Linux run "ss -ltnup 'sport = :2624'", on macOS "lsof -nP -i :2624", and on Windows "netstat -ano | findstr :2624" to see the local process. From another machine, "nmap -p 2624 <host>" shows whether it is reachable.
