Is port 2998 dangerous?

We have no specific security note for port 2998. 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 2998, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2998'      # process listening on 2998
sudo lsof -nP -i :2998

macOS

sudo lsof -nP -i :2998

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2998 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2998
netstat -ano | findstr :2998

From another machine

nmap -p 2998 -sV <host>
sudo nmap -sU -p 2998 <host>
nc -zv <host> 2998

Block it in the firewall

sudo ufw deny 2998/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2998" -Direction Inbound -LocalPort 2998 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2998 used for?

Port 2998 is assigned by IANA to realsecure (Real Secure).

Is port 2998 TCP or UDP?

Port 2998 is registered for TCP and UDP.

Is it safe to open port 2998?

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 2998 is open?

On Linux run "ss -ltnup 'sport = :2998'", on macOS "lsof -nP -i :2998", and on Windows "netstat -ano | findstr :2998" to see the local process. From another machine, "nmap -p 2998 <host>" shows whether it is reachable.
