01 Security

Is port 5308 dangerous?

We have no specific security note for port 5308. 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 5308, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5308'      # process listening on 5308
sudo lsof -nP -i :5308

macOS

sudo lsof -nP -i :5308

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5308 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5308
netstat -ano | findstr :5308

From another machine

nmap -p 5308 -sV <host>
sudo nmap -sU -p 5308 <host>
nc -zv <host> 5308

Block it in the firewall

sudo ufw deny 5308/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5308" -Direction Inbound -LocalPort 5308 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5308 used for?

Port 5308 is assigned by IANA to cfengine (CFengine).

Is port 5308 TCP or UDP?

Port 5308 is registered for TCP and UDP.

Is it safe to open port 5308?

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 5308 is open?

On Linux run "ss -ltnup 'sport = :5308'", on macOS "lsof -nP -i :5308", and on Windows "netstat -ano | findstr :5308" to see the local process. From another machine, "nmap -p 5308 <host>" shows whether it is reachable.
