01 Security

Is port 5465 dangerous?

We have no specific security note for port 5465. 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 5465, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5465'      # process listening on 5465
sudo lsof -nP -i :5465

macOS

sudo lsof -nP -i :5465

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5465 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5465
netstat -ano | findstr :5465

From another machine

nmap -p 5465 -sV <host>
sudo nmap -sU -p 5465 <host>
nc -zv <host> 5465

Block it in the firewall

sudo ufw deny 5465/tcp                                         # Linux (ufw)

04 FAQ
What is port 5465 used for?

Port 5465 is assigned by IANA to netops-broker (NETOPS-BROKER).

Is port 5465 TCP or UDP?

Port 5465 is registered for TCP and UDP.

Is it safe to open port 5465?

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 5465 is open?

On Linux run "ss -ltnup 'sport = :5465'", on macOS "lsof -nP -i :5465", and on Windows "netstat -ano | findstr :5465" to see the local process. From another machine, "nmap -p 5465 <host>" shows whether it is reachable.
