Is port 5227 dangerous?

We have no specific security note for port 5227. Its risk depends on the program actually listening on it. General advice for monitoring & logging services:

  • Restrict management and monitoring protocols to the monitoring network.
  • Replace community strings and default credentials.
  • Send logs over TLS.

03 Check it

Which program uses port 5227, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5227'      # process listening on 5227
sudo lsof -nP -i :5227

macOS

sudo lsof -nP -i :5227

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5227 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5227
netstat -ano | findstr :5227

From another machine

nmap -p 5227 -sV <host>
sudo nmap -sU -p 5227 <host>
nc -zv <host> 5227

Block it in the firewall

sudo ufw deny 5227/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5227" -Direction Inbound -LocalPort 5227 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5227 used for?

Port 5227 is assigned by IANA to perfd (HP System Performance Metric Service).

Is port 5227 TCP or UDP?

Port 5227 is registered for TCP and UDP.

Is it safe to open port 5227?

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. Restrict management and monitoring protocols to the monitoring network.

How do I check if port 5227 is open?

On Linux run "ss -ltnup 'sport = :5227'", on macOS "lsof -nP -i :5227", and on Windows "netstat -ano | findstr :5227" to see the local process. From another machine, "nmap -p 5227 <host>" shows whether it is reachable.
