Smallnet Information Services
Smallnet Information Services (SIS) is a server software suite that plays a similar role to Microsoft’s Internet Information Services (IIS), but for protocols in the small internet ecosystem. SIS provides integrated server support for Gemini, Gopher, Nex/NPS, Spartan, Misfin, Scroll, and Titan protocols. Using the built-in SIS Manager interface (accessed via Gemini), administrators can configure and manage multiple virtual servers across different protocols, defining their hostnames, certificates, and protocol-specific settings from a single administrative console.
