01 Security

Is port 7201 dangerous?

We have no specific security note for port 7201. 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 7201, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7201'      # process listening on 7201
sudo lsof -nP -i :7201

macOS

sudo lsof -nP -i :7201

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7201 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7201
netstat -ano | findstr :7201

From another machine

nmap -p 7201 -sV <host>
sudo nmap -sU -p 7201 <host>
nc -zv <host> 7201

Block it in the firewall

sudo ufw deny 7201/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7201" -Direction Inbound -LocalPort 7201 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 7201 used for?

Port 7201 is assigned by IANA to dlip (DLIP).

Is port 7201 TCP or UDP?

Port 7201 is registered for TCP and UDP.

Is it safe to open port 7201?

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 7201 is open?

On Linux run "ss -ltnup 'sport = :7201'", on macOS "lsof -nP -i :7201", and on Windows "netstat -ano | findstr :7201" to see the local process. From another machine, "nmap -p 7201 <host>" shows whether it is reachable.
