Is port 5461 dangerous?

We have no specific security note for port 5461. 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 5461, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5461'      # process listening on 5461
sudo lsof -nP -i :5461

macOS

sudo lsof -nP -i :5461

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5461 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5461
netstat -ano | findstr :5461

From another machine

nmap -p 5461 -sV <host>
sudo nmap -sU -p 5461 <host>
nc -zv <host> 5461

Block it in the firewall

sudo ufw deny 5461/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5461" -Direction Inbound -LocalPort 5461 -Protocol TCP -Action Block  # Windows

Is port 5461 TCP or UDP?

Port 5461 is registered for TCP and UDP.

Is it safe to open port 5461?

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 5461 is open?

On Linux run "ss -ltnup 'sport = :5461'", on macOS "lsof -nP -i :5461", and on Windows "netstat -ano | findstr :5461" to see the local process. From another machine, "nmap -p 5461 <host>" shows whether it is reachable.
