01 Security

Is port 4175 dangerous?

We have no specific security note for port 4175. Its risk depends on the program actually listening on it. General advice for devops, cloud & containers services:

  • Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.
  • Never expose them to the Internet.
  • Rotate tokens and certificates and audit who has access.

03 Check it

Which program uses port 4175, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4175'      # process listening on 4175
sudo lsof -nP -i :4175

macOS

sudo lsof -nP -i :4175

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4175 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4175
netstat -ano | findstr :4175

From another machine

nmap -p 4175 -sV <host>
nc -zv <host> 4175

Block it in the firewall

sudo ufw deny 4175/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4175" -Direction Inbound -LocalPort 4175 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4175 used for?

Port 4175 is assigned by IANA to bccp (Brocade Cluster Communication Protocol).

Is port 4175 TCP or UDP?

Port 4175 is registered for TCP.

Is it safe to open port 4175?

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. Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.

How do I check if port 4175 is open?

On Linux run "ss -ltnup 'sport = :4175'", on macOS "lsof -nP -i :4175", and on Windows "netstat -ano | findstr :4175" to see the local process. From another machine, "nmap -p 4175 <host>" shows whether it is reachable.
