01 Security

Is port 3617 dangerous?

We have no specific security note for port 3617. 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 3617, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3617'      # process listening on 3617
sudo lsof -nP -i :3617

macOS

sudo lsof -nP -i :3617

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3617 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3617
netstat -ano | findstr :3617

From another machine

nmap -p 3617 -sV <host>
sudo nmap -sU -p 3617 <host>
nc -zv <host> 3617

Block it in the firewall

sudo ufw deny 3617/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3617" -Direction Inbound -LocalPort 3617 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3617 used for?

Port 3617 is assigned by IANA to sharp-server (ATI SHARP Logic Engine).

Is port 3617 TCP or UDP?

Port 3617 is registered for TCP and UDP.

Is it safe to open port 3617?

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 3617 is open?

On Linux run "ss -ltnup 'sport = :3617'", on macOS "lsof -nP -i :3617", and on Windows "netstat -ano | findstr :3617" to see the local process. From another machine, "nmap -p 3617 <host>" shows whether it is reachable.
