This is an SNMP server for small and embedded systems, currently Linux and FreeBSD are supported. It is easily portable to other UNIX systems since it’s written in C. The daemon is very small (~40 kiB) and does not have nowhere near the feature set of Net-SNMP, therefore it has a very low impact on system resources. See my mini HowTo: Playing with SNMP for a quick introduction to setting up the SNMP tools and MIBs to avoid having to use numerical OIDs.
