01 Security

Is port 4095 dangerous?

We have no specific security note for port 4095. 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 4095, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4095'      # process listening on 4095
sudo lsof -nP -i :4095

macOS

sudo lsof -nP -i :4095

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4095 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4095
netstat -ano | findstr :4095

From another machine

nmap -p 4095 -sV <host>
sudo nmap -sU -p 4095 <host>
nc -zv <host> 4095

Block it in the firewall

sudo ufw deny 4095/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4095" -Direction Inbound -LocalPort 4095 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4095 used for?

Port 4095 is assigned by IANA to xtgui (xtgui information service).

Is port 4095 TCP or UDP?

Port 4095 is registered for TCP and UDP.

Is it safe to open port 4095?

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 4095 is open?

On Linux run "ss -ltnup 'sport = :4095'", on macOS "lsof -nP -i :4095", and on Windows "netstat -ano | findstr :4095" to see the local process. From another machine, "nmap -p 4095 <host>" shows whether it is reachable.
