01 Security

Is port 4700 dangerous?

We have no specific security note for port 4700. 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 4700, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4700'      # process listening on 4700
sudo lsof -nP -i :4700

macOS

sudo lsof -nP -i :4700

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4700 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4700
netstat -ano | findstr :4700

From another machine

nmap -p 4700 -sV <host>
sudo nmap -sU -p 4700 <host>
nc -zv <host> 4700

Block it in the firewall

sudo ufw deny 4700/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4700" -Direction Inbound -LocalPort 4700 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4700 used for?

Port 4700 is assigned by IANA to netxms-agent (NetXMS Agent).

Is port 4700 TCP or UDP?

Port 4700 is registered for TCP and UDP.

Is it safe to open port 4700?

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 4700 is open?

On Linux run "ss -ltnup 'sport = :4700'", on macOS "lsof -nP -i :4700", and on Windows "netstat -ano | findstr :4700" to see the local process. From another machine, "nmap -p 4700 <host>" shows whether it is reachable.
