Is port 4110 dangerous?

We have no specific security note for port 4110. Its risk depends on the program actually listening on it. General advice for monitoring & logging services:

  • Restrict management and monitoring protocols to the monitoring network.
  • Replace community strings and default credentials.
  • Send logs over TLS.

03 Check it

Which program uses port 4110, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4110'      # process listening on 4110
sudo lsof -nP -i :4110

macOS

sudo lsof -nP -i :4110

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4110 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4110
netstat -ano | findstr :4110

From another machine

nmap -p 4110 -sV <host>
sudo nmap -sU -p 4110 <host>
nc -zv <host> 4110

Block it in the firewall

sudo ufw deny 4110/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4110" -Direction Inbound -LocalPort 4110 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4110 used for?

Port 4110 is assigned by IANA to g2tag (G2 RFID Tag Telemetry Data).

Is port 4110 TCP or UDP?

Port 4110 is registered for TCP and UDP.

Is it safe to open port 4110?

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. Restrict management and monitoring protocols to the monitoring network.

How do I check if port 4110 is open?

On Linux run "ss -ltnup 'sport = :4110'", on macOS "lsof -nP -i :4110", and on Windows "netstat -ano | findstr :4110" to see the local process. From another machine, "nmap -p 4110 <host>" shows whether it is reachable.
