01 Security

Is port 2458 dangerous?

We have no specific security note for port 2458. 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 2458, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2458'      # process listening on 2458
sudo lsof -nP -i :2458

macOS

sudo lsof -nP -i :2458

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2458 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2458
netstat -ano | findstr :2458

From another machine

nmap -p 2458 -sV <host>
sudo nmap -sU -p 2458 <host>
nc -zv <host> 2458

Block it in the firewall

sudo ufw deny 2458/tcp                                         # Linux (ufw)

What is port 2458 used for?

Port 2458 is assigned by IANA to griffin (griffin).

Is port 2458 TCP or UDP?

Port 2458 is registered for TCP and UDP.

Is it safe to open port 2458?

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 2458 is open?

On Linux run "ss -ltnup 'sport = :2458'", on macOS "lsof -nP -i :2458", and on Windows "netstat -ano | findstr :2458" to see the local process. From another machine, "nmap -p 2458 <host>" shows whether it is reachable.
