01 Security

Is port 1268 dangerous?

We have no specific security note for port 1268. 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 1268, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1268'      # process listening on 1268
sudo lsof -nP -i :1268

macOS

sudo lsof -nP -i :1268

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1268 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1268
netstat -ano | findstr :1268

From another machine

nmap -p 1268 -sV <host>
sudo nmap -sU -p 1268 <host>
nc -zv <host> 1268

Block it in the firewall

sudo ufw deny 1268/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1268" -Direction Inbound -LocalPort 1268 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1268 used for?

Port 1268 is assigned by IANA to propel-msgsys (PROPEL-MSGSYS).

Is port 1268 TCP or UDP?

Port 1268 is registered for TCP and UDP.

Is it safe to open port 1268?

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 1268 is open?

On Linux run "ss -ltnup 'sport = :1268'", on macOS "lsof -nP -i :1268", and on Windows "netstat -ano | findstr :1268" to see the local process. From another machine, "nmap -p 1268 <host>" shows whether it is reachable.
