01 Security

Is port 5235 dangerous?

We have no specific security note for port 5235. 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 5235, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5235'      # process listening on 5235
sudo lsof -nP -i :5235

macOS

sudo lsof -nP -i :5235

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5235 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5235
netstat -ano | findstr :5235

From another machine

nmap -p 5235 -sV <host>
sudo nmap -sU -p 5235 <host>
nc -zv <host> 5235

Block it in the firewall

sudo ufw deny 5235/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5235" -Direction Inbound -LocalPort 5235 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5235 used for?

Port 5235 is assigned by IANA to galaxy-network (Galaxy Network Service).

Is port 5235 TCP or UDP?

Port 5235 is registered for TCP and UDP.

Is it safe to open port 5235?

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 5235 is open?

On Linux run "ss -ltnup 'sport = :5235'", on macOS "lsof -nP -i :5235", and on Windows "netstat -ano | findstr :5235" to see the local process. From another machine, "nmap -p 5235 <host>" shows whether it is reachable.
