Is port 7165 dangerous?

We have no specific security note for port 7165. 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 7165, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7165'      # process listening on 7165
sudo lsof -nP -i :7165

macOS

sudo lsof -nP -i :7165

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7165 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7165
netstat -ano | findstr :7165

From another machine

nmap -p 7165 -sV <host>
sudo nmap -sU -p 7165 <host>
nc -zv <host> 7165

Block it in the firewall

sudo ufw deny 7165/tcp                                         # Linux (ufw)

What is port 7165 used for?

Port 7165 is assigned by IANA to doc-server (Document WCF Server).

Is port 7165 TCP or UDP?

Port 7165 is registered for TCP and UDP.

Is it safe to open port 7165?

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 7165 is open?

On Linux run "ss -ltnup 'sport = :7165'", on macOS "lsof -nP -i :7165", and on Windows "netstat -ano | findstr :7165" to see the local process. From another machine, "nmap -p 7165 <host>" shows whether it is reachable.
