01 Security

Is port 7631 dangerous?

We have no specific security note for port 7631. 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 7631, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7631'      # process listening on 7631
sudo lsof -nP -i :7631

macOS

sudo lsof -nP -i :7631

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7631 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7631
netstat -ano | findstr :7631

From another machine

nmap -p 7631 -sV <host>
nc -zv <host> 7631

Block it in the firewall

sudo ufw deny 7631/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7631" -Direction Inbound -LocalPort 7631 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 7631 used for?

Port 7631 is assigned by IANA to tesla-sys-msg (TESLA System Messaging).

Is port 7631 TCP or UDP?

Port 7631 is registered for TCP.

Is it safe to open port 7631?

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 7631 is open?

On Linux run "ss -ltnup 'sport = :7631'", on macOS "lsof -nP -i :7631", and on Windows "netstat -ano | findstr :7631" to see the local process. From another machine, "nmap -p 7631 <host>" shows whether it is reachable.
