Though I might wonder why you're implementing it by hand rather than using something existing (since you're already using net-snmp). Well, because I'm using the utilities from net-snmp (under Win7/64) to test our agent, but the agent itself is running on an ARM9 core, with 96KB RAM and 512KB FLASH.聛0聞2 I had hand-coded all our existing snmp v1 and v2 support by reverse-engineering Wireshark packet dumps of interactions between net-snmp utilities and net-snmp snmpd running on another machine.聛0聞2 Unfortunately, that isn't so simple with the authentication/encryption requirements of v3!!聛0聞2 So my current plan is to identify the minimum set of functions that I need to extract from net-snmp into our firmware to get this job done. I have merged snmplib/openssl into our firmware, which takes up about 31KB.聛0聞2 But I definitely cannot pull in all of snmplib itself (over 66,000 lines).聛0聞2 So I'm tracing snmpget.c, along with the agent, to figure out what the minimum set of functionality that I need to pull in, to handle the auth/encryption, and then link them to my existing hand-coded snmp packet handlers. My current theory is that I should be able to extract generate_Ku() and whatever function it calls, to handle the tasks that I don't already know how to handle, but I've got some further analysis of the agent to go before I'll know if that is reasonable... https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient&utm_term=icon Virus-free. www.avast.com ------------------------------------------------------------------------------ Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
