01 Security

Is port 7017 dangerous?

We have no specific security note for port 7017. 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 7017, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7017'      # process listening on 7017
sudo lsof -nP -i :7017

macOS

sudo lsof -nP -i :7017

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7017 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7017
netstat -ano | findstr :7017

From another machine

nmap -p 7017 -sV <host>
sudo nmap -sU -p 7017 <host>
nc -zv <host> 7017

Block it in the firewall

sudo ufw deny 7017/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7017" -Direction Inbound -LocalPort 7017 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 7017 used for?

Port 7017 is assigned by IANA to grasp (GeneRic Autonomic Signaling Protocol).

Is port 7017 TCP or UDP?

Port 7017 is registered for TCP and UDP.

Is it safe to open port 7017?

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 7017 is open?

On Linux run "ss -ltnup 'sport = :7017'", on macOS "lsof -nP -i :7017", and on Windows "netstat -ano | findstr :7017" to see the local process. From another machine, "nmap -p 7017 <host>" shows whether it is reachable.
