Is port 23005 dangerous?

We have no specific security note for port 23005. 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 23005, and is it reachable?

Linux

sudo ss -ltnup 'sport = :23005'      # process listening on 23005
sudo lsof -nP -i :23005

macOS

sudo lsof -nP -i :23005

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 23005 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 23005
netstat -ano | findstr :23005

From another machine

nmap -p 23005 -sV <host>
sudo nmap -sU -p 23005 <host>
nc -zv <host> 23005

Block it in the firewall

sudo ufw deny 23005/tcp                                         # Linux (ufw)

04 FAQ
What is port 23005 used for?

Port 23005 is assigned by IANA to inovaport6 (Inova LightLink Server Type 6).

Is port 23005 TCP or UDP?

Port 23005 is registered for TCP and UDP.

Is it safe to open port 23005?

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 23005 is open?

On Linux run "ss -ltnup 'sport = :23005'", on macOS "lsof -nP -i :23005", and on Windows "netstat -ano | findstr :23005" to see the local process. From another machine, "nmap -p 23005 <host>" shows whether it is reachable.
