Is port 3629 dangerous?

We have no specific security note for port 3629. 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 3629, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3629'      # process listening on 3629
sudo lsof -nP -i :3629

macOS

sudo lsof -nP -i :3629

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3629 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3629
netstat -ano | findstr :3629

From another machine

nmap -p 3629 -sV <host>
sudo nmap -sU -p 3629 <host>
nc -zv <host> 3629

Block it in the firewall

sudo ufw deny 3629/tcp                                         # Linux (ufw)
