01 Security

Is port 1067 dangerous?

We have no specific security note for port 1067. 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 1067, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1067'      # process listening on 1067
sudo lsof -nP -i :1067

macOS

sudo lsof -nP -i :1067

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1067 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1067
netstat -ano | findstr :1067

From another machine

nmap -p 1067 -sV <host>
sudo nmap -sU -p 1067 <host>
nc -zv <host> 1067

Block it in the firewall

sudo ufw deny 1067/tcp                                         # Linux (ufw)

04 FAQ
What is port 1067 used for?

Port 1067 is assigned by IANA to instl_boots (Installation Bootstrap Proto. Serv.), instl-boots (Installation Bootstrap Proto. Serv. IANA assigned this well-formed service name as a replacement for "instl_boots".).

Is port 1067 TCP or UDP?

Port 1067 is registered for TCP and UDP.

Is it safe to open port 1067?

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 1067 is open?

On Linux run "ss -ltnup 'sport = :1067'", on macOS "lsof -nP -i :1067", and on Windows "netstat -ano | findstr :1067" to see the local process. From another machine, "nmap -p 1067 <host>" shows whether it is reachable.
