01 Security

Is port 3379 dangerous?

We have no specific security note for port 3379. 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 3379, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3379'      # process listening on 3379
sudo lsof -nP -i :3379

macOS

sudo lsof -nP -i :3379

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3379 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3379
netstat -ano | findstr :3379

From another machine

nmap -p 3379 -sV <host>
sudo nmap -sU -p 3379 <host>
nc -zv <host> 3379

Block it in the firewall

sudo ufw deny 3379/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3379" -Direction Inbound -LocalPort 3379 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3379 used for?

Port 3379 is assigned by IANA to socorfs (SOCORFS).

Is port 3379 TCP or UDP?

Port 3379 is registered for TCP and UDP.

Is it safe to open port 3379?

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 3379 is open?

On Linux run "ss -ltnup 'sport = :3379'", on macOS "lsof -nP -i :3379", and on Windows "netstat -ano | findstr :3379" to see the local process. From another machine, "nmap -p 3379 <host>" shows whether it is reachable.
