01 Security

Is port 5229 dangerous?

We have no specific security note for port 5229. 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 5229, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5229'      # process listening on 5229
sudo lsof -nP -i :5229

macOS

sudo lsof -nP -i :5229

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5229 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5229
netstat -ano | findstr :5229

From another machine

nmap -p 5229 -sV <host>
nc -zv <host> 5229

Block it in the firewall

sudo ufw deny 5229/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5229" -Direction Inbound -LocalPort 5229 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5229 used for?

Port 5229 is assigned by IANA to jaxflow (Netflow/IPFIX/sFlow Collector and Forwarder Management).

Is port 5229 TCP or UDP?

Port 5229 is registered for TCP.

Is it safe to open port 5229?

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 5229 is open?

On Linux run "ss -ltnup 'sport = :5229'", on macOS "lsof -nP -i :5229", and on Windows "netstat -ano | findstr :5229" to see the local process. From another machine, "nmap -p 5229 <host>" shows whether it is reachable.
