01 Security

Is port 1927 dangerous?

We have no specific security note for port 1927. 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 1927, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1927'      # process listening on 1927
sudo lsof -nP -i :1927

macOS

sudo lsof -nP -i :1927

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1927 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1927
netstat -ano | findstr :1927

From another machine

nmap -p 1927 -sV <host>
sudo nmap -sU -p 1927 <host>
nc -zv <host> 1927

Block it in the firewall

sudo ufw deny 1927/tcp                                         # Linux (ufw)

04 FAQ
What is port 1927 used for?

Port 1927 is assigned by IANA to videte-cipc (Videte CIPC Port).

Is port 1927 TCP or UDP?

Port 1927 is registered for TCP and UDP.

Is it safe to open port 1927?

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 1927 is open?

On Linux run "ss -ltnup 'sport = :1927'", on macOS "lsof -nP -i :1927", and on Windows "netstat -ano | findstr :1927" to see the local process. From another machine, "nmap -p 1927 <host>" shows whether it is reachable.
