01 Security

Is port 213 dangerous?

We have no specific security note for port 213. 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 213, and is it reachable?

Linux

sudo ss -ltnup 'sport = :213'      # process listening on 213
sudo lsof -nP -i :213

macOS

sudo lsof -nP -i :213

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 213 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 213
netstat -ano | findstr :213

From another machine

nmap -p 213 -sV <host>
sudo nmap -sU -p 213 <host>
nc -zv <host> 213

Block it in the firewall

sudo ufw deny 213/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 213" -Direction Inbound -LocalPort 213 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 213 used for?

Port 213 is assigned by IANA to ipx (IPX).

Is port 213 TCP or UDP?

Port 213 is registered for TCP and UDP.

Is it safe to open port 213?

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 213 is open?

On Linux run "ss -ltnup 'sport = :213'", on macOS "lsof -nP -i :213", and on Windows "netstat -ano | findstr :213" to see the local process. From another machine, "nmap -p 213 <host>" shows whether it is reachable.
