TheSSS (The Smallest Server Suite) is a lightweight server suite distributed as a live CD. It is designed for system administrators who need an extremely tiny and fast set of server software. The supported servers are: DNS, FTP, HTTP, MySQL, NFS, SFTP, SMTP, SSH, and Telnet. A proxy server (Polipo with optional Tor support) is also included. The main security components are the 4MLinux Firewall (based on iptables) and Clam AntiVirus. ISO images are fully compatible with UNetbootin, which can be used to create an easy-to-use TheSSS Live USB.
The latest version 37.1 is based on the 4MLinux Server 37.1.
