01 Security

Is port 1459 dangerous?

We have no specific security note for port 1459. 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 1459, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1459'      # process listening on 1459
sudo lsof -nP -i :1459

macOS

sudo lsof -nP -i :1459

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1459 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1459
netstat -ano | findstr :1459

From another machine

nmap -p 1459 -sV <host>
sudo nmap -sU -p 1459 <host>
nc -zv <host> 1459

Block it in the firewall

sudo ufw deny 1459/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1459" -Direction Inbound -LocalPort 1459 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1459 used for?

Port 1459 is assigned by IANA to proshare1 (Proshare Notebook Application).

Is port 1459 TCP or UDP?

Port 1459 is registered for TCP and UDP.

Is it safe to open port 1459?

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 1459 is open?

On Linux run "ss -ltnup 'sport = :1459'", on macOS "lsof -nP -i :1459", and on Windows "netstat -ano | findstr :1459" to see the local process. From another machine, "nmap -p 1459 <host>" shows whether it is reachable.
