Development Server
What is Port 3005?
Port 3005 is used as a development server port for various web applications and services. It's commonly encountered when multiple development services are running simultaneously and lower-numbered ports like 3000-3004 are already in use. Some specific tools and frameworks configure port 3005 as their default — for instance, certain microservice configurations, development proxy servers, and testing environments. In containerized development environments, port 3005 might be mapped from a container's internal port to the host. Like other ports in the 3000-3999 range, it's part of the IANA-registered port range and primarily associated with development and internal services.
Common Uses
- Web application development servers
- Microservice development and testing
- Container port mapping for development
- Additional service endpoint in multi-service setups
Technical Details
Copy-paste commands to check port 3005 (Development Server) from your terminal
Test connectivity
nc -zv example.com 3005
curl -v --max-time 5 http://example.com:3005/
telnet example.com 3005
nmap -p 3005 -sV example.com
(echo > /dev/tcp/example.com/3005) 2>/dev/null && echo "open" || echo "closed"
Open port in firewall
sudo ufw allow 3005/tcp
sudo iptables -A INPUT -p tcp --dport 3005 -j ACCEPT
sudo firewall-cmd --permanent --add-port=3005/tcp && sudo firewall-cmd --reload
Security Considerations
Development servers should bind to localhost and not be exposed to external networks. Use reverse proxies with proper authentication for any services that need to be accessible beyond the development machine. Ensure development ports are closed in production firewall configurations.
