Is port 1217 dangerous?

We have no specific security note for port 1217. 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 1217, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1217'      # process listening on 1217
sudo lsof -nP -i :1217

macOS

sudo lsof -nP -i :1217

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1217 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1217
netstat -ano | findstr :1217

From another machine

nmap -p 1217 -sV <host>
sudo nmap -sU -p 1217 <host>
nc -zv <host> 1217

Block it in the firewall

sudo ufw deny 1217/tcp                                         # Linux (ufw)

04 FAQ
What is port 1217 used for?

Port 1217 is assigned by IANA to hpss-ndapi (HPSS NonDCE Gateway).

Is port 1217 TCP or UDP?

Port 1217 is registered for TCP and UDP.

Is it safe to open port 1217?

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 1217 is open?

On Linux run "ss -ltnup 'sport = :1217'", on macOS "lsof -nP -i :1217", and on Windows "netstat -ano | findstr :1217" to see the local process. From another machine, "nmap -p 1217 <host>" shows whether it is reachable.
