Is port 7880 dangerous?

We have no specific security note for port 7880. 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 7880, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7880'      # process listening on 7880
sudo lsof -nP -i :7880

macOS

sudo lsof -nP -i :7880

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7880 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7880
netstat -ano | findstr :7880

From another machine

nmap -p 7880 -sV <host>
sudo nmap -sU -p 7880 <host>
nc -zv <host> 7880

Block it in the firewall

sudo ufw deny 7880/tcp                                         # Linux (ufw)

04 FAQ
What is port 7880 used for?

Port 7880 is assigned by IANA to pss (Pearson).

Is port 7880 TCP or UDP?

Port 7880 is registered for TCP and UDP.

Is it safe to open port 7880?

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 7880 is open?

On Linux run "ss -ltnup 'sport = :7880'", on macOS "lsof -nP -i :7880", and on Windows "netstat -ano | findstr :7880" to see the local process. From another machine, "nmap -p 7880 <host>" shows whether it is reachable.
