01 Security

Is port 2325 dangerous?

We have no specific security note for port 2325. 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 2325, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2325'      # process listening on 2325
sudo lsof -nP -i :2325

macOS

sudo lsof -nP -i :2325

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2325 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2325
netstat -ano | findstr :2325

From another machine

nmap -p 2325 -sV <host>
sudo nmap -sU -p 2325 <host>
nc -zv <host> 2325

Block it in the firewall

sudo ufw deny 2325/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2325" -Direction Inbound -LocalPort 2325 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2325 used for?

Port 2325 is assigned by IANA to ansysli (ANSYS Licensing Interconnect).

Is port 2325 TCP or UDP?

Port 2325 is registered for TCP and UDP.

Is it safe to open port 2325?

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 2325 is open?

On Linux run "ss -ltnup 'sport = :2325'", on macOS "lsof -nP -i :2325", and on Windows "netstat -ano | findstr :2325" to see the local process. From another machine, "nmap -p 2325 <host>" shows whether it is reachable.
