01 Security

Is port 8710 dangerous?

We have no specific security note for port 8710. 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 8710, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8710'      # process listening on 8710
sudo lsof -nP -i :8710

macOS

sudo lsof -nP -i :8710

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8710 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8710
netstat -ano | findstr :8710

From another machine

nmap -p 8710 -sV <host>
nc -zv <host> 8710

Block it in the firewall

sudo ufw deny 8710/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 8710" -Direction Inbound -LocalPort 8710 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 8710 used for?

Port 8710 is assigned by IANA to semi-grpc (gRPC for SEMI Standards implementations).

Is port 8710 TCP or UDP?

Port 8710 is registered for TCP.

Is it safe to open port 8710?

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 8710 is open?

On Linux run "ss -ltnup 'sport = :8710'", on macOS "lsof -nP -i :8710", and on Windows "netstat -ano | findstr :8710" to see the local process. From another machine, "nmap -p 8710 <host>" shows whether it is reachable.
