Is port 1706 dangerous?

We have no specific security note for port 1706. 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 1706, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1706'      # process listening on 1706
sudo lsof -nP -i :1706

macOS

sudo lsof -nP -i :1706

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1706 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1706
netstat -ano | findstr :1706

From another machine

nmap -p 1706 -sV <host>
sudo nmap -sU -p 1706 <host>
nc -zv <host> 1706

Block it in the firewall

sudo ufw deny 1706/tcp                                         # Linux (ufw)

04 FAQ
What is port 1706 used for?

Port 1706 is assigned by IANA to jetform (jetform).

Is port 1706 TCP or UDP?

Port 1706 is registered for TCP and UDP.

Is it safe to open port 1706?

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 1706 is open?

On Linux run "ss -ltnup 'sport = :1706'", on macOS "lsof -nP -i :1706", and on Windows "netstat -ano | findstr :1706" to see the local process. From another machine, "nmap -p 1706 <host>" shows whether it is reachable.
