01 Security

Is port 1297 dangerous?

We have no specific security note for port 1297. 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 1297, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1297'      # process listening on 1297
sudo lsof -nP -i :1297

macOS

sudo lsof -nP -i :1297

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1297 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1297
netstat -ano | findstr :1297

From another machine

nmap -p 1297 -sV <host>
sudo nmap -sU -p 1297 <host>
nc -zv <host> 1297

Block it in the firewall

sudo ufw deny 1297/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1297" -Direction Inbound -LocalPort 1297 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1297 used for?

Port 1297 is assigned by IANA to sdproxy (sdproxy).

Is port 1297 TCP or UDP?

Port 1297 is registered for TCP and UDP.

Is it safe to open port 1297?

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 1297 is open?

On Linux run "ss -ltnup 'sport = :1297'", on macOS "lsof -nP -i :1297", and on Windows "netstat -ano | findstr :1297" to see the local process. From another machine, "nmap -p 1297 <host>" shows whether it is reachable.
