Well the most important information about these two release branches is that they are both obsolete. No development or support work is being done on either of them. > Is there some advantage to work with the net snmp's version?And why? Advantages to the Net-SNMP code over UCD: - several years of bug fixes and additional functionality - some vague chance of support > How did the snmp's agent change? The main change was the switch to a handler-chain based approach for implementing MIB modules, rather than the UCD "old-api" mechanism. There's plenty of information about this on the project website, FAQ, tutorials, etc A number of the MIB modules have been re-written over the last eight years to take advantage of the handler-based approach. So the newer releases will support more MIBs on a wider range of architectures. Have a look at the NEWS and CHANGES files for the various releases to get a feel for some of what has changed. > What are the differences on: > -the data structures, > -interfaces (API), > -traps management, > -real time constraints. In general, we've tried to keep backward compatability as much as possible. But the switch from UCD to Net-SNMP did involve things like changing the location of header files (<ucd-snmp/xxx> to <net-snmp/xxx>). Also some of the data structures now have the prefix "netsnmp_" compared with the earlier UCD versions. But the internal structures are much the same. I can't be any more specific, I'm afraid - it's been eight years since we've done anything significant with the old UCD code.
