  • 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 34249, and is it reachable?

Linux

sudo ss -ltnup 'sport = :34249'      # process listening on 34249
sudo lsof -nP -i :34249

macOS

sudo lsof -nP -i :34249

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 34249 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 34249
netstat -ano | findstr :34249

From another machine

nmap -p 34249 -sV <host>
sudo nmap -sU -p 34249 <host>
nc -zv <host> 34249

Block it in the firewall

sudo ufw deny 34249/tcp                                         # Linux (ufw)

04 FAQ
What is port 34249 used for?

Port 34249 is assigned by IANA to turbonote-2 (TurboNote Relay Server Default Port).

Is port 34249 TCP or UDP?

Port 34249 is registered for TCP and UDP.

Is it safe to open port 34249?

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 34249 is open?

On Linux run "ss -ltnup 'sport = :34249'", on macOS "lsof -nP -i :34249", and on Windows "netstat -ano | findstr :34249" to see the local process. From another machine, "nmap -p 34249 <host>" shows whether it is reachable.
