01 Security

Is port 5434 dangerous?

We have no specific security note for port 5434. 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 5434, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5434'      # process listening on 5434
sudo lsof -nP -i :5434

macOS

sudo lsof -nP -i :5434

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5434 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5434
netstat -ano | findstr :5434

From another machine

nmap -p 5434 -sV <host>
sudo nmap -sU -p 5434 <host>
nc -zv <host> 5434

Block it in the firewall

sudo ufw deny 5434/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5434" -Direction Inbound -LocalPort 5434 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5434 used for?

Port 5434 is assigned by IANA to sgi-arrayd (SGI Array Services Daemon).

Is port 5434 TCP or UDP?

Port 5434 is registered for TCP and UDP.

Is it safe to open port 5434?

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 5434 is open?

On Linux run "ss -ltnup 'sport = :5434'", on macOS "lsof -nP -i :5434", and on Windows "netstat -ano | findstr :5434" to see the local process. From another machine, "nmap -p 5434 <host>" shows whether it is reachable.
