01 Security

Is port 6629 dangerous?

We have no specific security note for port 6629. 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 6629, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6629'      # process listening on 6629
sudo lsof -nP -i :6629

macOS

sudo lsof -nP -i :6629

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6629 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6629
netstat -ano | findstr :6629

From another machine

nmap -p 6629 -sV <host>
sudo nmap -sU -p 6629 <host>
nc -zv <host> 6629

Block it in the firewall

sudo ufw deny 6629/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 6629" -Direction Inbound -LocalPort 6629 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 6629 used for?

Port 6629 is assigned by IANA to nexgen-aux (Secondary, (non ANDI) multi-protocol multi-function interface to the Allied ANDI-based family of forecourt controllers).

Is port 6629 TCP or UDP?

Port 6629 is registered for TCP and UDP.

Is it safe to open port 6629?

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 6629 is open?

On Linux run "ss -ltnup 'sport = :6629'", on macOS "lsof -nP -i :6629", and on Windows "netstat -ano | findstr :6629" to see the local process. From another machine, "nmap -p 6629 <host>" shows whether it is reachable.
