01 Security

Is port 2495 dangerous?

We have no specific security note for port 2495. 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 2495, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2495'      # process listening on 2495
sudo lsof -nP -i :2495

macOS

sudo lsof -nP -i :2495

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2495 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2495
netstat -ano | findstr :2495

From another machine

nmap -p 2495 -sV <host>
sudo nmap -sU -p 2495 <host>
nc -zv <host> 2495

Block it in the firewall

sudo ufw deny 2495/tcp                                         # Linux (ufw)

What is port 2495 used for?

Port 2495 is assigned by IANA to fast-rem-serv (Fast Remote Services).

Is port 2495 TCP or UDP?

Port 2495 is registered for TCP and UDP.

Is it safe to open port 2495?

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 2495 is open?

On Linux run "ss -ltnup 'sport = :2495'", on macOS "lsof -nP -i :2495", and on Windows "netstat -ano | findstr :2495" to see the local process. From another machine, "nmap -p 2495 <host>" shows whether it is reachable.
