01 Security

Is port 1380 dangerous?

We have no specific security note for port 1380. 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 1380, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1380'      # process listening on 1380
sudo lsof -nP -i :1380

macOS

sudo lsof -nP -i :1380

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1380 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1380
netstat -ano | findstr :1380

From another machine

nmap -p 1380 -sV <host>
sudo nmap -sU -p 1380 <host>
nc -zv <host> 1380

Block it in the firewall

sudo ufw deny 1380/tcp                                         # Linux (ufw)

04 FAQ
What is port 1380 used for?

Port 1380 is assigned by IANA to telesis-licman (Telesis Network License Manager).

Is port 1380 TCP or UDP?

Port 1380 is registered for TCP and UDP.

Is it safe to open port 1380?

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 1380 is open?

On Linux run "ss -ltnup 'sport = :1380'", on macOS "lsof -nP -i :1380", and on Windows "netstat -ano | findstr :1380" to see the local process. From another machine, "nmap -p 1380 <host>" shows whether it is reachable.
