01 Security

Is port 1979 dangerous?

We have no specific security note for port 1979. 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 1979, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1979'      # process listening on 1979
sudo lsof -nP -i :1979

macOS

sudo lsof -nP -i :1979

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1979 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1979
netstat -ano | findstr :1979

From another machine

nmap -p 1979 -sV <host>
sudo nmap -sU -p 1979 <host>
nc -zv <host> 1979

Block it in the firewall

sudo ufw deny 1979/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1979" -Direction Inbound -LocalPort 1979 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1979 used for?

Port 1979 is assigned by IANA to unisql-java (UniSQL Java).

Is port 1979 TCP or UDP?

Port 1979 is registered for TCP and UDP.

Is it safe to open port 1979?

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 1979 is open?

On Linux run "ss -ltnup 'sport = :1979'", on macOS "lsof -nP -i :1979", and on Windows "netstat -ano | findstr :1979" to see the local process. From another machine, "nmap -p 1979 <host>" shows whether it is reachable.
