TheSSS has been designed for system admins who need a lightweight (TheSSS LiveCD is less than 30MB in size) set of server software for small Local Area Networks. The supported servers are: FTP, HTTP, SFTP, SSH, and Telnet. A proxy server (Polipo) with Tor anonymizer is also included. The main security components are 4MLinux Firewall (based on iptables) and Clam AntiVirus. TheSSS iso images are fully compatible with UNetbootin, which can be used to create an easy-to-use TheSSS Live USB.
Simple to use.
