01 Security

Is port 1359 dangerous?

We have no specific security note for port 1359. 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 1359, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1359'      # process listening on 1359
sudo lsof -nP -i :1359

macOS

sudo lsof -nP -i :1359

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1359 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1359
netstat -ano | findstr :1359

From another machine

nmap -p 1359 -sV <host>
sudo nmap -sU -p 1359 <host>
nc -zv <host> 1359

Block it in the firewall

sudo ufw deny 1359/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1359" -Direction Inbound -LocalPort 1359 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1359 used for?

Port 1359 is assigned by IANA to ftsrv (FTSRV).

Is port 1359 TCP or UDP?

Port 1359 is registered for TCP and UDP.

Is it safe to open port 1359?

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 1359 is open?

On Linux run "ss -ltnup 'sport = :1359'", on macOS "lsof -nP -i :1359", and on Windows "netstat -ano | findstr :1359" to see the local process. From another machine, "nmap -p 1359 <host>" shows whether it is reachable.
