01 Security

Is port 2975 dangerous?

We have no specific security note for port 2975. 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 2975, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2975'      # process listening on 2975
sudo lsof -nP -i :2975

macOS

sudo lsof -nP -i :2975

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2975 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2975
netstat -ano | findstr :2975

From another machine

nmap -p 2975 -sV <host>
sudo nmap -sU -p 2975 <host>
nc -zv <host> 2975

Block it in the firewall

sudo ufw deny 2975/tcp                                         # Linux (ufw)

Port 2975 is assigned by IANA to fjmpcm (Fujitsu Configuration Management Service).

Is port 2975 TCP or UDP?

Port 2975 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 2975 is open?

On Linux run "ss -ltnup 'sport = :2975'", on macOS "lsof -nP -i :2975", and on Windows "netstat -ano | findstr :2975" to see the local process. From another machine, "nmap -p 2975 <host>" shows whether it is reachable.
