Is port 2108 dangerous?

We have no specific security note for port 2108. 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 2108, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2108'      # process listening on 2108
sudo lsof -nP -i :2108

macOS

sudo lsof -nP -i :2108

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2108 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2108
netstat -ano | findstr :2108

From another machine

nmap -p 2108 -sV <host>
sudo nmap -sU -p 2108 <host>
nc -zv <host> 2108

Block it in the firewall

sudo ufw deny 2108/tcp                                         # Linux (ufw)

04 FAQ
What is port 2108 used for?

Port 2108 is assigned by IANA to comcam (Comcam).

Is port 2108 TCP or UDP?

Port 2108 is registered for TCP and UDP.

Is it safe to open port 2108?

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 2108 is open?

On Linux run "ss -ltnup 'sport = :2108'", on macOS "lsof -nP -i :2108", and on Windows "netstat -ano | findstr :2108" to see the local process. From another machine, "nmap -p 2108 <host>" shows whether it is reachable.
