01 Security

Is port 8005 dangerous?

We have no specific security note for port 8005. 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 8005, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8005'      # process listening on 8005
sudo lsof -nP -i :8005

macOS

sudo lsof -nP -i :8005

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8005 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8005
netstat -ano | findstr :8005

From another machine

nmap -p 8005 -sV <host>
sudo nmap -sU -p 8005 <host>
nc -zv <host> 8005

Block it in the firewall

sudo ufw deny 8005/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 8005" -Direction Inbound -LocalPort 8005 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 8005 used for?

Port 8005 is assigned by IANA to mxi (MXI Generation II for z/OS).

Is port 8005 TCP or UDP?

Port 8005 is registered for TCP and UDP.

Is it safe to open port 8005?

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 8005 is open?

On Linux run "ss -ltnup 'sport = :8005'", on macOS "lsof -nP -i :8005", and on Windows "netstat -ano | findstr :8005" to see the local process. From another machine, "nmap -p 8005 <host>" shows whether it is reachable.
