01 Security

Is port 1038 dangerous?

We have no specific security note for port 1038. 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 1038, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1038'      # process listening on 1038
sudo lsof -nP -i :1038

macOS

sudo lsof -nP -i :1038

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1038 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1038
netstat -ano | findstr :1038

From another machine

nmap -p 1038 -sV <host>
sudo nmap -sU -p 1038 <host>
nc -zv <host> 1038

Block it in the firewall

sudo ufw deny 1038/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1038" -Direction Inbound -LocalPort 1038 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1038 used for?

Port 1038 is assigned by IANA to mtqp (Message Tracking Query Protocol).

Is port 1038 TCP or UDP?

Port 1038 is registered for TCP and UDP.

Is it safe to open port 1038?

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 1038 is open?

On Linux run "ss -ltnup 'sport = :1038'", on macOS "lsof -nP -i :1038", and on Windows "netstat -ano | findstr :1038" to see the local process. From another machine, "nmap -p 1038 <host>" shows whether it is reachable.
