Is port 7099 dangerous?

We have no specific security note for port 7099. 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 7099, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7099'      # process listening on 7099
sudo lsof -nP -i :7099

macOS

sudo lsof -nP -i :7099

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7099 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7099
netstat -ano | findstr :7099

From another machine

nmap -p 7099 -sV <host>
sudo nmap -sU -p 7099 <host>
nc -zv <host> 7099

Block it in the firewall

sudo ufw deny 7099/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7099" -Direction Inbound -LocalPort 7099 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 7099 used for?

Port 7099 is assigned by IANA to lazy-ptop (lazy-ptop).

Is port 7099 TCP or UDP?

Port 7099 is registered for TCP and UDP.

Is it safe to open port 7099?

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 7099 is open?

On Linux run "ss -ltnup 'sport = :7099'", on macOS "lsof -nP -i :7099", and on Windows "netstat -ano | findstr :7099" to see the local process. From another machine, "nmap -p 7099 <host>" shows whether it is reachable.
