Is port 776 dangerous?

We have no specific security note for port 776. 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 776, and is it reachable?

Linux

sudo ss -ltnup 'sport = :776'      # process listening on 776
sudo lsof -nP -i :776

macOS

sudo lsof -nP -i :776

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 776 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 776
netstat -ano | findstr :776

From another machine

nmap -p 776 -sV <host>
sudo nmap -sU -p 776 <host>
nc -zv <host> 776

Block it in the firewall

sudo ufw deny 776/tcp                                         # Linux (ufw)

Port 776 is assigned by IANA to wpages ().

Is port 776 TCP or UDP?

Port 776 is registered for TCP and UDP.

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 776 is open?

On Linux run "ss -ltnup 'sport = :776'", on macOS "lsof -nP -i :776", and on Windows "netstat -ano | findstr :776" to see the local process. From another machine, "nmap -p 776 <host>" shows whether it is reachable.
