Is port 3808 dangerous?

We have no specific security note for port 3808. 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 3808, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3808'      # process listening on 3808
sudo lsof -nP -i :3808

macOS

sudo lsof -nP -i :3808

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3808 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3808
netstat -ano | findstr :3808

From another machine

nmap -p 3808 -sV <host>
sudo nmap -sU -p 3808 <host>
nc -zv <host> 3808

Block it in the firewall

sudo ufw deny 3808/tcp                                         # Linux (ufw)

What is port 3808 used for?

Port 3808 is assigned by IANA to sun-as-iiops-ca (Sun App Svr-IIOPClntAuth).

Is port 3808 TCP or UDP?

Port 3808 is registered for TCP and UDP.

Is it safe to open port 3808?

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 3808 is open?

On Linux run "ss -ltnup 'sport = :3808'", on macOS "lsof -nP -i :3808", and on Windows "netstat -ano | findstr :3808" to see the local process. From another machine, "nmap -p 3808 <host>" shows whether it is reachable.
