01 Security

Is port 1150 dangerous?

We have no specific security note for port 1150. Its risk depends on the program actually listening on it. General advice for file transfer & sharing services:

  • Prefer encrypted protocols (SFTP, FTPS, SMB 3 with encryption).
  • Disable anonymous access and restrict shares or exports to known hosts.
  • Never publish file sharing protocols to the Internet.

03 Check it

Which program uses port 1150, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1150'      # process listening on 1150
sudo lsof -nP -i :1150

macOS

sudo lsof -nP -i :1150

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1150 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1150
netstat -ano | findstr :1150

From another machine

nmap -p 1150 -sV <host>
sudo nmap -sU -p 1150 <host>
nc -zv <host> 1150

Block it in the firewall

sudo ufw deny 1150/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1150" -Direction Inbound -LocalPort 1150 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1150 used for?

Port 1150 is assigned by IANA to blaze (Blaze File Server).

Is port 1150 TCP or UDP?

Port 1150 is registered for TCP and UDP.

Is it safe to open port 1150?

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. Prefer encrypted protocols (SFTP, FTPS, SMB 3 with encryption).

How do I check if port 1150 is open?

On Linux run "ss -ltnup 'sport = :1150'", on macOS "lsof -nP -i :1150", and on Windows "netstat -ano | findstr :1150" to see the local process. From another machine, "nmap -p 1150 <host>" shows whether it is reachable.
