01 Security

Is port 1505 dangerous?

We have no specific security note for port 1505. 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 1505, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1505'      # process listening on 1505
sudo lsof -nP -i :1505

macOS

sudo lsof -nP -i :1505

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1505 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1505
netstat -ano | findstr :1505

From another machine

nmap -p 1505 -sV <host>
sudo nmap -sU -p 1505 <host>
nc -zv <host> 1505

Block it in the firewall

sudo ufw deny 1505/tcp                                         # Linux (ufw)

What is port 1505 used for?

Port 1505 is assigned by IANA to funkproxy (Funk Software, Inc.).

Is port 1505 TCP or UDP?

Port 1505 is registered for TCP and UDP.

Is it safe to open port 1505?

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 1505 is open?

On Linux run "ss -ltnup 'sport = :1505'", on macOS "lsof -nP -i :1505", and on Windows "netstat -ano | findstr :1505" to see the local process. From another machine, "nmap -p 1505 <host>" shows whether it is reachable.
