01 Security

Is port 3698 dangerous?

We have no specific security note for port 3698. 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 3698, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3698'      # process listening on 3698
sudo lsof -nP -i :3698

macOS

sudo lsof -nP -i :3698

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3698 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3698
netstat -ano | findstr :3698

From another machine

nmap -p 3698 -sV <host>
sudo nmap -sU -p 3698 <host>
nc -zv <host> 3698

Block it in the firewall

sudo ufw deny 3698/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3698" -Direction Inbound -LocalPort 3698 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3698 used for?

Port 3698 is assigned by IANA to sagectlpanel (SAGECTLPANEL).

Is port 3698 TCP or UDP?

Port 3698 is registered for TCP and UDP.

Is it safe to open port 3698?

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 3698 is open?

On Linux run "ss -ltnup 'sport = :3698'", on macOS "lsof -nP -i :3698", and on Windows "netstat -ano | findstr :3698" to see the local process. From another machine, "nmap -p 3698 <host>" shows whether it is reachable.
