01 Security

Is port 1368 dangerous?

We have no specific security note for port 1368. 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 1368, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1368'      # process listening on 1368
sudo lsof -nP -i :1368

macOS

sudo lsof -nP -i :1368

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1368 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1368
netstat -ano | findstr :1368

From another machine

nmap -p 1368 -sV <host>
sudo nmap -sU -p 1368 <host>
nc -zv <host> 1368

Block it in the firewall

sudo ufw deny 1368/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1368" -Direction Inbound -LocalPort 1368 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1368 used for?

Port 1368 is assigned by IANA to screencast (ScreenCast).

Is port 1368 TCP or UDP?

Port 1368 is registered for TCP and UDP.

Is it safe to open port 1368?

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 1368 is open?

On Linux run "ss -ltnup 'sport = :1368'", on macOS "lsof -nP -i :1368", and on Windows "netstat -ano | findstr :1368" to see the local process. From another machine, "nmap -p 1368 <host>" shows whether it is reachable.
