01 Security

Is port 3102 dangerous?

We have no specific security note for port 3102. 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 3102, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3102'      # process listening on 3102
sudo lsof -nP -i :3102

macOS

sudo lsof -nP -i :3102

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3102 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3102
netstat -ano | findstr :3102

From another machine

nmap -p 3102 -sV <host>
sudo nmap -sU -p 3102 <host>
nc -zv <host> 3102

Block it in the firewall

sudo ufw deny 3102/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3102" -Direction Inbound -LocalPort 3102 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3102 used for?

Port 3102 is assigned by IANA to slslavemon (SoftlinK Slave Mon Port).

Is port 3102 TCP or UDP?

Port 3102 is registered for TCP and UDP.

Is it safe to open port 3102?

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 3102 is open?

On Linux run "ss -ltnup 'sport = :3102'", on macOS "lsof -nP -i :3102", and on Windows "netstat -ano | findstr :3102" to see the local process. From another machine, "nmap -p 3102 <host>" shows whether it is reachable.
