Is port 3035 dangerous?

We have no specific security note for port 3035. 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 3035, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3035'      # process listening on 3035
sudo lsof -nP -i :3035

macOS

sudo lsof -nP -i :3035

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3035 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3035
netstat -ano | findstr :3035

From another machine

nmap -p 3035 -sV <host>
sudo nmap -sU -p 3035 <host>
nc -zv <host> 3035

Block it in the firewall

sudo ufw deny 3035/tcp                                         # Linux (ufw)

04 FAQ
What is port 3035 used for?

Port 3035 is assigned by IANA to fjsv-gssagt (FJSV gssagt).

Is port 3035 TCP or UDP?

Port 3035 is registered for TCP and UDP.

Is it safe to open port 3035?

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 3035 is open?

On Linux run "ss -ltnup 'sport = :3035'", on macOS "lsof -nP -i :3035", and on Windows "netstat -ano | findstr :3035" to see the local process. From another machine, "nmap -p 3035 <host>" shows whether it is reachable.
