Is port 3278 dangerous?

We have no specific security note for port 3278. 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 3278, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3278'      # process listening on 3278
sudo lsof -nP -i :3278

macOS

sudo lsof -nP -i :3278

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3278 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3278
netstat -ano | findstr :3278

From another machine

nmap -p 3278 -sV <host>
sudo nmap -sU -p 3278 <host>
nc -zv <host> 3278

Block it in the firewall

sudo ufw deny 3278/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3278" -Direction Inbound -LocalPort 3278 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3278 used for?

Port 3278 is assigned by IANA to lkcmserver (LKCM Server).

Is port 3278 TCP or UDP?

Port 3278 is registered for TCP and UDP.

Is it safe to open port 3278?

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 3278 is open?

On Linux run "ss -ltnup 'sport = :3278'", on macOS "lsof -nP -i :3278", and on Windows "netstat -ano | findstr :3278" to see the local process. From another machine, "nmap -p 3278 <host>" shows whether it is reachable.
