Is port 1769 dangerous?

We have no specific security note for port 1769. 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 1769, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1769'      # process listening on 1769
sudo lsof -nP -i :1769

macOS

sudo lsof -nP -i :1769

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1769 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1769
netstat -ano | findstr :1769

From another machine

nmap -p 1769 -sV <host>
sudo nmap -sU -p 1769 <host>
nc -zv <host> 1769

Block it in the firewall

sudo ufw deny 1769/tcp                                         # Linux (ufw)

Port 1769 is assigned by IANA to bmc-net-adm (bmc-net-adm).

Is port 1769 TCP or UDP?

Port 1769 is registered for TCP and UDP.

Is it safe to open port 1769?

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 1769 is open?

On Linux run "ss -ltnup 'sport = :1769'", on macOS "lsof -nP -i :1769", and on Windows "netstat -ano | findstr :1769" to see the local process. From another machine, "nmap -p 1769 <host>" shows whether it is reachable.
