01 Security

Is port 269 dangerous?

We have no specific security note for port 269. 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 269, and is it reachable?

Linux

sudo ss -ltnup 'sport = :269'      # process listening on 269
sudo lsof -nP -i :269

macOS

sudo lsof -nP -i :269

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 269 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 269
netstat -ano | findstr :269

From another machine

nmap -p 269 -sV <host>
sudo nmap -sU -p 269 <host>
nc -zv <host> 269

Block it in the firewall

sudo ufw deny 269/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 269" -Direction Inbound -LocalPort 269 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 269 used for?

Port 269 is assigned by IANA to manet (MANET Protocols).

Is port 269 TCP or UDP?

Port 269 is registered for TCP and UDP.

Is it safe to open port 269?

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 269 is open?

On Linux run "ss -ltnup 'sport = :269'", on macOS "lsof -nP -i :269", and on Windows "netstat -ano | findstr :269" to see the local process. From another machine, "nmap -p 269 <host>" shows whether it is reachable.
