Is port 5464 dangerous?

We have no specific security note for port 5464. 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 5464, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5464'      # process listening on 5464
sudo lsof -nP -i :5464

macOS

sudo lsof -nP -i :5464

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5464 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5464
netstat -ano | findstr :5464

From another machine

nmap -p 5464 -sV <host>
sudo nmap -sU -p 5464 <host>
nc -zv <host> 5464

Block it in the firewall

sudo ufw deny 5464/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5464" -Direction Inbound -LocalPort 5464 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5464 used for?

Port 5464 is assigned by IANA to quailnet (Quail Networks Object Broker).

Is port 5464 TCP or UDP?

Port 5464 is registered for TCP and UDP.

Is it safe to open port 5464?

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 5464 is open?

On Linux run "ss -ltnup 'sport = :5464'", on macOS "lsof -nP -i :5464", and on Windows "netstat -ano | findstr :5464" to see the local process. From another machine, "nmap -p 5464 <host>" shows whether it is reachable.
