01 Security

Is port 2078 dangerous?

We have no specific security note for port 2078. 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 2078, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2078'      # process listening on 2078
sudo lsof -nP -i :2078

macOS

sudo lsof -nP -i :2078

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2078 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2078
netstat -ano | findstr :2078

From another machine

nmap -p 2078 -sV <host>
sudo nmap -sU -p 2078 <host>
nc -zv <host> 2078

Block it in the firewall

sudo ufw deny 2078/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2078" -Direction Inbound -LocalPort 2078 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2078 used for?

Port 2078 is assigned by IANA to tpcsrvr (IBM Total Productivity Center Server).

Is port 2078 TCP or UDP?

Port 2078 is registered for TCP and UDP.

Is it safe to open port 2078?

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 2078 is open?

On Linux run "ss -ltnup 'sport = :2078'", on macOS "lsof -nP -i :2078", and on Windows "netstat -ano | findstr :2078" to see the local process. From another machine, "nmap -p 2078 <host>" shows whether it is reachable.
