01 Security

Is port 364 dangerous?

We have no specific security note for port 364. 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 364, and is it reachable?

Linux

sudo ss -ltnup 'sport = :364'      # process listening on 364
sudo lsof -nP -i :364

macOS

sudo lsof -nP -i :364

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 364 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 364
netstat -ano | findstr :364

From another machine

nmap -p 364 -sV <host>
sudo nmap -sU -p 364 <host>
nc -zv <host> 364

Block it in the firewall

sudo ufw deny 364/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 364" -Direction Inbound -LocalPort 364 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 364 used for?

Port 364 is assigned by IANA to aurora-cmgr (Aurora CMGR).

Is port 364 TCP or UDP?

Port 364 is registered for TCP and UDP.

Is it safe to open port 364?

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 364 is open?

On Linux run "ss -ltnup 'sport = :364'", on macOS "lsof -nP -i :364", and on Windows "netstat -ano | findstr :364" to see the local process. From another machine, "nmap -p 364 <host>" shows whether it is reachable.
