01 Security

Is port 3464 dangerous?

We have no specific security note for port 3464. 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 3464, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3464'      # process listening on 3464
sudo lsof -nP -i :3464

macOS

sudo lsof -nP -i :3464

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3464 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3464
netstat -ano | findstr :3464

From another machine

nmap -p 3464 -sV <host>
sudo nmap -sU -p 3464 <host>
nc -zv <host> 3464

Block it in the firewall

sudo ufw deny 3464/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3464" -Direction Inbound -LocalPort 3464 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3464 used for?

Port 3464 is assigned by IANA to edm-mgr-sync (EDM MGR Sync).

Is port 3464 TCP or UDP?

Port 3464 is registered for TCP and UDP.

Is it safe to open port 3464?

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 3464 is open?

On Linux run "ss -ltnup 'sport = :3464'", on macOS "lsof -nP -i :3464", and on Windows "netstat -ano | findstr :3464" to see the local process. From another machine, "nmap -p 3464 <host>" shows whether it is reachable.
