01 Security

Is port 2835 dangerous?

We have no specific security note for port 2835. 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 2835, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2835'      # process listening on 2835
sudo lsof -nP -i :2835

macOS

sudo lsof -nP -i :2835

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2835 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2835
netstat -ano | findstr :2835

From another machine

nmap -p 2835 -sV <host>
sudo nmap -sU -p 2835 <host>
nc -zv <host> 2835

Block it in the firewall

sudo ufw deny 2835/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2835" -Direction Inbound -LocalPort 2835 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2835 used for?

Port 2835 is assigned by IANA to evtp-data (EVTP-DATA).

Is port 2835 TCP or UDP?

Port 2835 is registered for TCP and UDP.

Is it safe to open port 2835?

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 2835 is open?

On Linux run "ss -ltnup 'sport = :2835'", on macOS "lsof -nP -i :2835", and on Windows "netstat -ano | findstr :2835" to see the local process. From another machine, "nmap -p 2835 <host>" shows whether it is reachable.
