01 Security

Is port 468 dangerous?

We have no specific security note for port 468. 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 468, and is it reachable?

Linux

sudo ss -ltnup 'sport = :468'      # process listening on 468
sudo lsof -nP -i :468

macOS

sudo lsof -nP -i :468

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 468 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 468
netstat -ano | findstr :468

From another machine

nmap -p 468 -sV <host>
sudo nmap -sU -p 468 <host>
nc -zv <host> 468

Block it in the firewall

sudo ufw deny 468/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 468" -Direction Inbound -LocalPort 468 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 468 used for?

Port 468 is assigned by IANA to photuris (proturis).

Is port 468 TCP or UDP?

Port 468 is registered for TCP and UDP.

Is it safe to open port 468?

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 468 is open?

On Linux run "ss -ltnup 'sport = :468'", on macOS "lsof -nP -i :468", and on Windows "netstat -ano | findstr :468" to see the local process. From another machine, "nmap -p 468 <host>" shows whether it is reachable.
