01 Security

Is port 1910 dangerous?

We have no specific security note for port 1910. 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 1910, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1910'      # process listening on 1910
sudo lsof -nP -i :1910

macOS

sudo lsof -nP -i :1910

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1910 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1910
netstat -ano | findstr :1910

From another machine

nmap -p 1910 -sV <host>
sudo nmap -sU -p 1910 <host>
nc -zv <host> 1910

Block it in the firewall

sudo ufw deny 1910/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1910" -Direction Inbound -LocalPort 1910 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1910 used for?

Port 1910 is assigned by IANA to ultrabac (UltraBac Software communications port).

Is port 1910 TCP or UDP?

Port 1910 is registered for TCP and UDP.

Is it safe to open port 1910?

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 1910 is open?

On Linux run "ss -ltnup 'sport = :1910'", on macOS "lsof -nP -i :1910", and on Windows "netstat -ano | findstr :1910" to see the local process. From another machine, "nmap -p 1910 <host>" shows whether it is reachable.
