01 Security

Is port 467 dangerous?

We have no specific security note for port 467. 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 467, and is it reachable?

Linux

sudo ss -ltnup 'sport = :467'      # process listening on 467
sudo lsof -nP -i :467

macOS

sudo lsof -nP -i :467

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 467 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 467
netstat -ano | findstr :467

From another machine

nmap -p 467 -sV <host>
sudo nmap -sU -p 467 <host>
nc -zv <host> 467

Block it in the firewall

sudo ufw deny 467/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 467" -Direction Inbound -LocalPort 467 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 467 used for?

Port 467 is assigned by IANA to mylex-mapd (mylex-mapd).

Is port 467 TCP or UDP?

Port 467 is registered for TCP and UDP.

Is it safe to open port 467?

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 467 is open?

On Linux run "ss -ltnup 'sport = :467'", on macOS "lsof -nP -i :467", and on Windows "netstat -ano | findstr :467" to see the local process. From another machine, "nmap -p 467 <host>" shows whether it is reachable.
