01 Security

Is port 5067 dangerous?

We have no specific security note for port 5067. 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 5067, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5067'      # process listening on 5067
sudo lsof -nP -i :5067

macOS

sudo lsof -nP -i :5067

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5067 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5067
netstat -ano | findstr :5067

From another machine

nmap -p 5067 -sV <host>
sudo nmap -sU -p 5067 <host>
nc -zv <host> 5067

Block it in the firewall

sudo ufw deny 5067/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5067" -Direction Inbound -LocalPort 5067 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5067 used for?

Port 5067 is assigned by IANA to authentx (Authentx Service).

Is port 5067 TCP or UDP?

Port 5067 is registered for TCP and UDP.

Is it safe to open port 5067?

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 5067 is open?

On Linux run "ss -ltnup 'sport = :5067'", on macOS "lsof -nP -i :5067", and on Windows "netstat -ano | findstr :5067" to see the local process. From another machine, "nmap -p 5067 <host>" shows whether it is reachable.
