Is port 7629 dangerous?

We have no specific security note for port 7629. 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 7629, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7629'      # process listening on 7629
sudo lsof -nP -i :7629

macOS

sudo lsof -nP -i :7629

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7629 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7629
netstat -ano | findstr :7629

From another machine

nmap -p 7629 -sV <host>
sudo nmap -sU -p 7629 <host>
nc -zv <host> 7629

Block it in the firewall

sudo ufw deny 7629/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7629" -Direction Inbound -LocalPort 7629 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 7629 used for?

Port 7629 is assigned by IANA to xdas (OpenXDAS Wire Protocol).

Is port 7629 TCP or UDP?

Port 7629 is registered for TCP and UDP.

Is it safe to open port 7629?

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 7629 is open?

On Linux run "ss -ltnup 'sport = :7629'", on macOS "lsof -nP -i :7629", and on Windows "netstat -ano | findstr :7629" to see the local process. From another machine, "nmap -p 7629 <host>" shows whether it is reachable.
