01 Security

Is port 9629 dangerous?

We have no specific security note for port 9629. Its risk depends on the program actually listening on it. General advice for directory & authentication services:

  • Keep directory and authentication services on internal networks.
  • Require signing or TLS and disable anonymous queries.
  • Monitor authentication failures for spraying and brute force.

03 Check it

Which program uses port 9629, and is it reachable?

Linux

sudo ss -ltnup 'sport = :9629'      # process listening on 9629
sudo lsof -nP -i :9629

macOS

sudo lsof -nP -i :9629

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 9629 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 9629
netstat -ano | findstr :9629

From another machine

nmap -p 9629 -sV <host>
sudo nmap -sU -p 9629 <host>
nc -zv <host> 9629

Block it in the firewall

sudo ufw deny 9629/tcp                                         # Linux (ufw)

Is port 9629 TCP or UDP?

Port 9629 is registered for TCP and UDP.

Is it safe to open port 9629?

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. Keep directory and authentication services on internal networks.

How do I check if port 9629 is open?

On Linux run "ss -ltnup 'sport = :9629'", on macOS "lsof -nP -i :9629", and on Windows "netstat -ano | findstr :9629" to see the local process. From another machine, "nmap -p 9629 <host>" shows whether it is reachable.
