Is port 3498 dangerous?

We have no specific security note for port 3498. 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 3498, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3498'      # process listening on 3498
sudo lsof -nP -i :3498

macOS

sudo lsof -nP -i :3498

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3498 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3498
netstat -ano | findstr :3498

From another machine

nmap -p 3498 -sV <host>
sudo nmap -sU -p 3498 <host>
nc -zv <host> 3498

Block it in the firewall

sudo ufw deny 3498/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3498" -Direction Inbound -LocalPort 3498 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3498 used for?

Port 3498 is assigned by IANA to dashpas-port (DASHPAS user port).

Is port 3498 TCP or UDP?

Port 3498 is registered for TCP and UDP.

Is it safe to open port 3498?

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 3498 is open?

On Linux run "ss -ltnup 'sport = :3498'", on macOS "lsof -nP -i :3498", and on Windows "netstat -ano | findstr :3498" to see the local process. From another machine, "nmap -p 3498 <host>" shows whether it is reachable.
