Is port 449 dangerous?

We have no specific security note for port 449. 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 449, and is it reachable?

Linux

sudo ss -ltnup 'sport = :449'      # process listening on 449
sudo lsof -nP -i :449

macOS

sudo lsof -nP -i :449

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 449 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 449
netstat -ano | findstr :449

From another machine

nmap -p 449 -sV <host>
sudo nmap -sU -p 449 <host>
nc -zv <host> 449

Block it in the firewall

sudo ufw deny 449/tcp                                         # Linux (ufw)

04 FAQ
What is port 449 used for?

Port 449 is assigned by IANA to as-servermap (AS Server Mapper).

Is port 449 TCP or UDP?

Port 449 is registered for TCP and UDP.

Is it safe to open port 449?

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 449 is open?

On Linux run "ss -ltnup 'sport = :449'", on macOS "lsof -nP -i :449", and on Windows "netstat -ano | findstr :449" to see the local process. From another machine, "nmap -p 449 <host>" shows whether it is reachable.
