01 Security

Is port 4701 dangerous?

We have no specific security note for port 4701. 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 4701, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4701'      # process listening on 4701
sudo lsof -nP -i :4701

macOS

sudo lsof -nP -i :4701

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4701 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4701
netstat -ano | findstr :4701

From another machine

nmap -p 4701 -sV <host>
sudo nmap -sU -p 4701 <host>
nc -zv <host> 4701

Block it in the firewall

sudo ufw deny 4701/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4701" -Direction Inbound -LocalPort 4701 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4701 used for?

Port 4701 is assigned by IANA to netxms-mgmt (NetXMS Management).

Is port 4701 TCP or UDP?

Port 4701 is registered for TCP and UDP.

Is it safe to open port 4701?

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 4701 is open?

On Linux run "ss -ltnup 'sport = :4701'", on macOS "lsof -nP -i :4701", and on Windows "netstat -ano | findstr :4701" to see the local process. From another machine, "nmap -p 4701 <host>" shows whether it is reachable.
