01 Security

Is port 3095 dangerous?

We have no specific security note for port 3095. 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 3095, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3095'      # process listening on 3095
sudo lsof -nP -i :3095

macOS

sudo lsof -nP -i :3095

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3095 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3095
netstat -ano | findstr :3095

From another machine

nmap -p 3095 -sV <host>
sudo nmap -sU -p 3095 <host>
nc -zv <host> 3095

Block it in the firewall

sudo ufw deny 3095/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3095" -Direction Inbound -LocalPort 3095 -Protocol TCP -Action Block  # Windows

What is port 3095 used for?

Port 3095 is assigned by IANA to panasas (Panasas rendezvous port).

Is port 3095 TCP or UDP?

Port 3095 is registered for TCP and UDP.

Is it safe to open port 3095?

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 3095 is open?

On Linux run "ss -ltnup 'sport = :3095'", on macOS "lsof -nP -i :3095", and on Windows "netstat -ano | findstr :3095" to see the local process. From another machine, "nmap -p 3095 <host>" shows whether it is reachable.
