01 Security

Is port 7798 dangerous?

We have no specific security note for port 7798. 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 7798, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7798'      # process listening on 7798
sudo lsof -nP -i :7798

macOS

sudo lsof -nP -i :7798

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7798 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7798
netstat -ano | findstr :7798

From another machine

nmap -p 7798 -sV <host>
sudo nmap -sU -p 7798 <host>
nc -zv <host> 7798

Block it in the firewall

sudo ufw deny 7798/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7798" -Direction Inbound -LocalPort 7798 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 7798 used for?

Port 7798 is assigned by IANA to pnet-enc (Propel Encoder port).

Is port 7798 TCP or UDP?

Port 7798 is registered for TCP and UDP.

Is it safe to open port 7798?

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 7798 is open?

On Linux run "ss -ltnup 'sport = :7798'", on macOS "lsof -nP -i :7798", and on Windows "netstat -ano | findstr :7798" to see the local process. From another machine, "nmap -p 7798 <host>" shows whether it is reachable.
