01 Security

Is port 1029 dangerous?

We have no specific security note for port 1029. 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 1029, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1029'      # process listening on 1029
sudo lsof -nP -i :1029

macOS

sudo lsof -nP -i :1029

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1029 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1029
netstat -ano | findstr :1029

From another machine

nmap -p 1029 -sV <host>
sudo nmap -sU -p 1029 <host>
nc -zv <host> 1029

Block it in the firewall

sudo ufw deny 1029/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1029" -Direction Inbound -LocalPort 1029 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1029 used for?

Port 1029 is assigned by IANA to solid-mux (Solid Mux Server).

Is port 1029 TCP or UDP?

Port 1029 is registered for TCP and UDP.

Is it safe to open port 1029?

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 1029 is open?

On Linux run "ss -ltnup 'sport = :1029'", on macOS "lsof -nP -i :1029", and on Windows "netstat -ano | findstr :1029" to see the local process. From another machine, "nmap -p 1029 <host>" shows whether it is reachable.
