Is port 22951 dangerous?

We have no specific security note for port 22951. 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 22951, and is it reachable?

Linux

sudo ss -ltnup 'sport = :22951'      # process listening on 22951
sudo lsof -nP -i :22951

macOS

sudo lsof -nP -i :22951

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 22951 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 22951
netstat -ano | findstr :22951

From another machine

nmap -p 22951 -sV <host>
sudo nmap -sU -p 22951 <host>
nc -zv <host> 22951

Block it in the firewall

Port 22951 is assigned by IANA to brf-gw (Telerate Information Platform WAN).

Is port 22951 TCP or UDP?

Port 22951 is registered for TCP and UDP.

Is it safe to open port 22951?

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 22951 is open?

On Linux run "ss -ltnup 'sport = :22951'", on macOS "lsof -nP -i :22951", and on Windows "netstat -ano | findstr :22951" to see the local process. From another machine, "nmap -p 22951 <host>" shows whether it is reachable.
