01 Security

Is port 3087 dangerous?

We have no specific security note for port 3087. 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 3087, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3087'      # process listening on 3087
sudo lsof -nP -i :3087

macOS

sudo lsof -nP -i :3087

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3087 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3087
netstat -ano | findstr :3087

From another machine

nmap -p 3087 -sV <host>
sudo nmap -sU -p 3087 <host>
nc -zv <host> 3087

Block it in the firewall

sudo ufw deny 3087/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3087" -Direction Inbound -LocalPort 3087 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3087 used for?

Port 3087 is assigned by IANA to asoki-sma (Asoki SMA).

Is port 3087 TCP or UDP?

Port 3087 is registered for TCP and UDP.

Is it safe to open port 3087?

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 3087 is open?

On Linux run "ss -ltnup 'sport = :3087'", on macOS "lsof -nP -i :3087", and on Windows "netstat -ano | findstr :3087" to see the local process. From another machine, "nmap -p 3087 <host>" shows whether it is reachable.
