Webmin
What is Port 10000?
Port 10000 is the default port for Webmin, a web-based system administration tool for Unix/Linux servers. Webmin provides a browser interface for managing user accounts, disk quotas, services, configuration files, package management, and more — replacing the need for manual command-line configuration. Created in 1997, Webmin supports modules for managing Apache, BIND DNS, MySQL, Postfix, and dozens of other services. Its companion tool, Virtualmin (port 10000 with a different path), adds web hosting management capabilities. Webmin is particularly popular among system administrators who manage multiple Linux servers and prefer a GUI for common administration tasks.
Common Uses
- Linux/Unix server administration via web browser
- Service configuration and management

curl -v --max-time 5 http://example.com:10000/
telnet example.com 10000
nmap -p 10000 -sV example.com
(echo > /dev/tcp/example.com/10000) 2>/dev/null && echo "open" || echo "closed"
Open port in firewall
sudo ufw allow 10000/tcp
sudo iptables -A INPUT -p tcp --dport 10000 -j ACCEPT
sudo firewall-cmd --permanent --add-port=10000/tcp && sudo firewall-cmd --reload
Security Considerations
Webmin provides root-level access to the system and is a high-value target. Always use HTTPS (Webmin redirects to HTTPS by default). Restrict access to specific IP addresses. Use strong passwords and enable two-factor authentication. Webmin has had remote code execution vulnerabilities — keep it updated. Consider whether Webmin is necessary or if SSH access suffices.
