Is port 2758 dangerous?

We have no specific security note for port 2758. 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 2758, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2758'      # process listening on 2758
sudo lsof -nP -i :2758

macOS

sudo lsof -nP -i :2758

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2758 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2758
netstat -ano | findstr :2758

From another machine

nmap -p 2758 -sV <host>
sudo nmap -sU -p 2758 <host>
nc -zv <host> 2758

Block it in the firewall

sudo ufw deny 2758/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2758" -Direction Inbound -LocalPort 2758 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2758 used for?

Port 2758 is assigned by IANA to apollo-status (APOLLO Status).

Is port 2758 TCP or UDP?

Port 2758 is registered for TCP and UDP.

Is it safe to open port 2758?

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 2758 is open?

On Linux run "ss -ltnup 'sport = :2758'", on macOS "lsof -nP -i :2758", and on Windows "netstat -ano | findstr :2758" to see the local process. From another machine, "nmap -p 2758 <host>" shows whether it is reachable.
