01 Security

Is port 2059 dangerous?

We have no specific security note for port 2059. 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 2059, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2059'      # process listening on 2059
sudo lsof -nP -i :2059

macOS

sudo lsof -nP -i :2059

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2059 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2059
netstat -ano | findstr :2059

From another machine

nmap -p 2059 -sV <host>
sudo nmap -sU -p 2059 <host>
nc -zv <host> 2059

Block it in the firewall

sudo ufw deny 2059/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2059" -Direction Inbound -LocalPort 2059 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2059 used for?

Port 2059 is assigned by IANA to bmc-messaging (BMC Messaging Service).

Is port 2059 TCP or UDP?

Port 2059 is registered for TCP and UDP.

Is it safe to open port 2059?

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 2059 is open?

On Linux run "ss -ltnup 'sport = :2059'", on macOS "lsof -nP -i :2059", and on Windows "netstat -ano | findstr :2059" to see the local process. From another machine, "nmap -p 2059 <host>" shows whether it is reachable.
