01 Security

Is port 313 dangerous?

We have no specific security note for port 313. 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 313, and is it reachable?

Linux

sudo ss -ltnup 'sport = :313'      # process listening on 313
sudo lsof -nP -i :313

macOS

sudo lsof -nP -i :313

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 313 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 313
netstat -ano | findstr :313

From another machine

nmap -p 313 -sV <host>
sudo nmap -sU -p 313 <host>
nc -zv <host> 313

Block it in the firewall

sudo ufw deny 313/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 313" -Direction Inbound -LocalPort 313 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 313 used for?

Port 313 is assigned by IANA to magenta-logic (Magenta Logic).

Is port 313 TCP or UDP?

Port 313 is registered for TCP and UDP.

Is it safe to open port 313?

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 313 is open?

On Linux run "ss -ltnup 'sport = :313'", on macOS "lsof -nP -i :313", and on Windows "netstat -ano | findstr :313" to see the local process. From another machine, "nmap -p 313 <host>" shows whether it is reachable.
