01 Security

Is port 1579 dangerous?

We have no specific security note for port 1579. 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 1579, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1579'      # process listening on 1579
sudo lsof -nP -i :1579

macOS

sudo lsof -nP -i :1579

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1579 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1579
netstat -ano | findstr :1579

From another machine

nmap -p 1579 -sV <host>
sudo nmap -sU -p 1579 <host>
nc -zv <host> 1579

Block it in the firewall

sudo ufw deny 1579/tcp                                         # Linux (ufw)

04 FAQ
What is port 1579 used for?

Port 1579 is assigned by IANA to ioc-sea-lm (ioc-sea-lm).

Is port 1579 TCP or UDP?

Port 1579 is registered for TCP and UDP.

Is it safe to open port 1579?

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 1579 is open?

On Linux run "ss -ltnup 'sport = :1579'", on macOS "lsof -nP -i :1579", and on Windows "netstat -ano | findstr :1579" to see the local process. From another machine, "nmap -p 1579 <host>" shows whether it is reachable.
