How mngsuite works

The client opens a session to port 9535: each command typed is sent to the server, which runs it and returns the output.

01 Security

Is port 9535 dangerous?

We have no specific security note for port 9535. Its risk depends on the program actually listening on it. General advice for remote access services:

  • Do not expose remote administration directly: use a VPN or a zero-trust access proxy.
  • Require MFA or key-based authentication and lock out brute-force attempts.
  • Log every login and alert on new source addresses.

03 Check it

Which program uses port 9535, and is it reachable?

Linux

sudo ss -ltnup 'sport = :9535'      # process listening on 9535
sudo lsof -nP -i :9535

macOS

sudo lsof -nP -i :9535

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 9535 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 9535
netstat -ano | findstr :9535

From another machine

nmap -p 9535 -sV <host>
sudo nmap -sU -p 9535 <host>
nc -zv <host> 9535

Block it in the firewall

sudo ufw deny 9535/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 9535" -Direction Inbound -LocalPort 9535 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 9535 used for?

Port 9535 is assigned by IANA to mngsuite (Management Suite Remote Control).

Is port 9535 TCP or UDP?

Port 9535 is registered for TCP and UDP.

Is it safe to open port 9535?

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. Do not expose remote administration directly: use a VPN or a zero-trust access proxy.

How do I check if port 9535 is open?

On Linux run "ss -ltnup 'sport = :9535'", on macOS "lsof -nP -i :9535", and on Windows "netstat -ano | findstr :9535" to see the local process. From another machine, "nmap -p 9535 <host>" shows whether it is reachable.
