Is port 7810 dangerous?

We have no specific security note for port 7810. 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 7810, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7810'      # process listening on 7810
sudo lsof -nP -i :7810

macOS

sudo lsof -nP -i :7810

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7810 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7810
netstat -ano | findstr :7810

From another machine

nmap -p 7810 -sV <host>
sudo nmap -sU -p 7810 <host>
nc -zv <host> 7810

Block it in the firewall

sudo ufw deny 7810/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7810" -Direction Inbound -LocalPort 7810 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 7810 used for?

Port 7810 is assigned by IANA to rbt-wanopt (Riverbed WAN Optimization Protocol).

Is port 7810 TCP or UDP?

Port 7810 is registered for TCP and UDP.

Is it safe to open port 7810?

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 7810 is open?

On Linux run "ss -ltnup 'sport = :7810'", on macOS "lsof -nP -i :7810", and on Windows "netstat -ano | findstr :7810" to see the local process. From another machine, "nmap -p 7810 <host>" shows whether it is reachable.
