01 Security

Is port 5215 dangerous?

We have no specific security note for port 5215. 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 5215, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5215'      # process listening on 5215
sudo lsof -nP -i :5215

macOS

sudo lsof -nP -i :5215

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5215 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5215
netstat -ano | findstr :5215

From another machine

nmap -p 5215 -sV <host>
nc -zv <host> 5215

Block it in the firewall

sudo ufw deny 5215/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5215" -Direction Inbound -LocalPort 5215 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5215 used for?

Port 5215 is assigned by IANA to noteza (NOTEZA Data Safety Service).

Is port 5215 TCP or UDP?

Port 5215 is registered for TCP and SCTP.

Is it safe to open port 5215?

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 5215 is open?

On Linux run "ss -ltnup 'sport = :5215'", on macOS "lsof -nP -i :5215", and on Windows "netstat -ano | findstr :5215" to see the local process. From another machine, "nmap -p 5215 <host>" shows whether it is reachable.
