01 Security

Is port 7095 dangerous?

We have no specific security note for port 7095. Its risk depends on the program actually listening on it. General advice for network services services:

  • Answer only the networks that need the service (no open resolvers, relays or reflectors).
  • UDP services can be abused for DDoS amplification: rate-limit or block them at the edge.
  • Disable legacy test services that have no use in production.

03 Check it

Which program uses port 7095, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7095'      # process listening on 7095
sudo lsof -nP -i :7095

macOS

sudo lsof -nP -i :7095

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7095 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7095
netstat -ano | findstr :7095

From another machine

nmap -p 7095 -sV <host>
sudo nmap -sU -p 7095 <host>
nc -zv <host> 7095

Block it in the firewall

sudo ufw deny 7095/udp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7095" -Direction Inbound -LocalPort 7095 -Protocol UDP -Action Block  # Windows
04 FAQ
What is port 7095 used for?

Port 7095 is assigned by IANA to jdp-disc (Java Discovery Protocol).

Is port 7095 TCP or UDP?

Port 7095 is registered for UDP.

Is it safe to open port 7095?

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. Answer only the networks that need the service (no open resolvers, relays or reflectors).

How do I check if port 7095 is open?

On Linux run "ss -ltnup 'sport = :7095'", on macOS "lsof -nP -i :7095", and on Windows "netstat -ano | findstr :7095" to see the local process. From another machine, "nmap -p 7095 <host>" shows whether it is reachable.
