Is port 1273 dangerous?

We have no specific security note for port 1273. 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 1273, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1273'      # process listening on 1273
sudo lsof -nP -i :1273

macOS

sudo lsof -nP -i :1273

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1273 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1273
netstat -ano | findstr :1273

From another machine

nmap -p 1273 -sV <host>
sudo nmap -sU -p 1273 <host>
nc -zv <host> 1273

Block it in the firewall

sudo ufw deny 1273/tcp                                         # Linux (ufw)

04 FAQ
What is port 1273 used for?

Port 1273 is assigned by IANA to emc-gateway (EMC-Gateway).

Is port 1273 TCP or UDP?

Port 1273 is registered for TCP and UDP.

Is it safe to open port 1273?

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 1273 is open?

On Linux run "ss -ltnup 'sport = :1273'", on macOS "lsof -nP -i :1273", and on Windows "netstat -ano | findstr :1273" to see the local process. From another machine, "nmap -p 1273 <host>" shows whether it is reachable.
