01 Security

Is port 3650 dangerous?

We have no specific security note for port 3650. 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 3650, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3650'      # process listening on 3650
sudo lsof -nP -i :3650

macOS

sudo lsof -nP -i :3650

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3650 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3650
netstat -ano | findstr :3650

From another machine

nmap -p 3650 -sV <host>
sudo nmap -sU -p 3650 <host>
nc -zv <host> 3650

Block it in the firewall

sudo ufw deny 3650/tcp                                         # Linux (ufw)

What is port 3650 used for?

Port 3650 is assigned by IANA to prismiq-plugin (PRISMIQ VOD plug-in).

Is port 3650 TCP or UDP?

Port 3650 is registered for TCP and UDP.

Is it safe to open port 3650?

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 3650 is open?

On Linux run "ss -ltnup 'sport = :3650'", on macOS "lsof -nP -i :3650", and on Windows "netstat -ano | findstr :3650" to see the local process. From another machine, "nmap -p 3650 <host>" shows whether it is reachable.
