01 Security

Is port 1264 dangerous?

We have no specific security note for port 1264. 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 1264, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1264'      # process listening on 1264
sudo lsof -nP -i :1264

macOS

sudo lsof -nP -i :1264

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1264 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1264
netstat -ano | findstr :1264

From another machine

nmap -p 1264 -sV <host>
sudo nmap -sU -p 1264 <host>
nc -zv <host> 1264

Block it in the firewall

sudo ufw deny 1264/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1264" -Direction Inbound -LocalPort 1264 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1264 used for?

Port 1264 is assigned by IANA to prat (PRAT).

Is port 1264 TCP or UDP?

Port 1264 is registered for TCP and UDP.

Is it safe to open port 1264?

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 1264 is open?

On Linux run "ss -ltnup 'sport = :1264'", on macOS "lsof -nP -i :1264", and on Windows "netstat -ano | findstr :1264" to see the local process. From another machine, "nmap -p 1264 <host>" shows whether it is reachable.
