Greetings, First, I just want to give my utmost thanks for an excellent project. I've been using Synapse for some time (first with Delphi, lately with FPC/Lazarus) and it's beyond excellent. Also, before I go any further, I just want to make it totally clear that my *entire* understanding of SNMP comes from looking at the Synapse SNMP-related code and reading RFCs, so if I say something stupid, I'm not really stupid... just ignorant. :)
I've made some additions to snmpsend.pas to allow implementation of an SNMP agent (server) which can do authentication (AuthNoPriv using MD5 and SHA1) of SNMP packets sent by SNMP clients. This code seems to work when both the server and the client are both written using FreePascal and Synapse. However, when I try to use another third-party SNMP library (particularly Net::SNMP with Perl) the same authentication code which works perfectly for Synapse-sent SNMP messages fails to authenticate the Net::SNMP-sent SNMP messages. I've kind of hit a brick wall with this. Since my authentication code works perfectly with the existing Synapse code for sending SNMP messages, but not with Net::SNMP, does that mean that there's something wrong with the existing Synapse code? Anyway, I'm hoping that someone among the Synapse developers or someone else on the mailing list would be willing to lend a second pair of eyes to this and help me figure out what I'm doing wrong. Here's a URL of a tarball containing what you need to duplicate what I'm doing: http://maemobox.org/tlacuache/snmpAuthTest.tar.gz This contains: - snmp-changes.patch = a patch generated against release 38 of the Synapse source code containing my modifications for SNMPv3 authentication - server = contains a small server program which listens for SNMP messages (traps and informrequests), authenticates them if needed and displays the contents - client = contains a test program for sending SNMP messages to the server (works perfectly for me with the server) - clientPerl = contains a perl script to send an SNMP message to the server (my server fails to authenticate it correctly) You should just be able to apply my patch to your synapse code and build the projects as-is (although I suppose you might need to change the unit search paths to point to the location of the synapse source code you patched). I'd certainly appreciate any help anyone could offer. Of course my hope is that all of the code I've written and anything else that comes from this could benefit the Synapse project. If you have any questions feel free to respond via the list, email me personally, or via skype (sethdgrover) or googletalk (sethdgrover). Thanks, -SG -- Good news, everyone!
