01 Security

Is port 6105 dangerous?

We have no specific security note for port 6105. 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 6105, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6105'      # process listening on 6105
sudo lsof -nP -i :6105

macOS

sudo lsof -nP -i :6105

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6105 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6105
netstat -ano | findstr :6105

From another machine

nmap -p 6105 -sV <host>
sudo nmap -sU -p 6105 <host>
nc -zv <host> 6105

Block it in the firewall

sudo ufw deny 6105/tcp                                         # Linux (ufw)

04 FAQ
What is port 6105 used for?

Port 6105 is assigned by IANA to primaserver (Prima Server).

Is port 6105 TCP or UDP?

Port 6105 is registered for TCP and UDP.

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 6105 is open?

On Linux run "ss -ltnup 'sport = :6105'", on macOS "lsof -nP -i :6105", and on Windows "netstat -ano | findstr :6105" to see the local process. From another machine, "nmap -p 6105 <host>" shows whether it is reachable.
