01 Security

Is port 5117 dangerous?

We have no specific security note for port 5117. 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 5117, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5117'      # process listening on 5117
sudo lsof -nP -i :5117

macOS

sudo lsof -nP -i :5117

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5117 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5117
netstat -ano | findstr :5117

From another machine

nmap -p 5117 -sV <host>
nc -zv <host> 5117

Block it in the firewall

sudo ufw deny 5117/tcp                                         # Linux (ufw)

04 FAQ
What is port 5117 used for?

Port 5117 is assigned by IANA to gradecam (GradeCam Image Processing).

Is port 5117 TCP or UDP?

Port 5117 is registered for TCP.

Is it safe to open port 5117?

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 5117 is open?

On Linux run "ss -ltnup 'sport = :5117'", on macOS "lsof -nP -i :5117", and on Windows "netstat -ano | findstr :5117" to see the local process. From another machine, "nmap -p 5117 <host>" shows whether it is reachable.
