01 Security

Is port 1382 dangerous?

We have no specific security note for port 1382. 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 1382, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1382'      # process listening on 1382
sudo lsof -nP -i :1382

macOS

sudo lsof -nP -i :1382

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1382 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1382
netstat -ano | findstr :1382

From another machine

nmap -p 1382 -sV <host>
sudo nmap -sU -p 1382 <host>
nc -zv <host> 1382

Block it in the firewall

sudo ufw deny 1382/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1382" -Direction Inbound -LocalPort 1382 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1382 used for?

Port 1382 is assigned by IANA to udt_os (udt_os), udt-os (udt_os IANA assigned this well-formed service name as a replacement for "udt_os".).

Is port 1382 TCP or UDP?

Port 1382 is registered for TCP and UDP.

Is it safe to open port 1382?

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 1382 is open?

On Linux run "ss -ltnup 'sport = :1382'", on macOS "lsof -nP -i :1382", and on Windows "netstat -ano | findstr :1382" to see the local process. From another machine, "nmap -p 1382 <host>" shows whether it is reachable.
