01 Security

Is port 2193 dangerous?

We have no specific security note for port 2193. Its risk depends on the program actually listening on it. General advice for web services:

  • Serve it over HTTPS only and check the HTTP security headers.
  • Keep admin consoles and development servers off the Internet.
  • Patch the application server and remove default credentials and sample apps.

03 Check it

Which program uses port 2193, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2193'      # process listening on 2193
sudo lsof -nP -i :2193

macOS

sudo lsof -nP -i :2193

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2193 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2193
netstat -ano | findstr :2193

From another machine

nmap -p 2193 -sV <host>
sudo nmap -sU -p 2193 <host>
nc -zv <host> 2193

Block it in the firewall

sudo ufw deny 2193/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2193" -Direction Inbound -LocalPort 2193 -Protocol TCP -Action Block  # Windows

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. Serve it over HTTPS only and check the HTTP security headers.
