How to validate libsmi functionality?
by Mark W. Alexander 01 Oct '02

01 Oct '02

Greetings all, Thanks for your work on libsmi. I'm working on a python application to connect snmp traps to a TCP stream oriented management application and I've found libsmi to be exactly what I need to decode trap PDU's to tokens and arguments that the management application can parse. To do so, I've implemented a hand coded Python wrapper around (so far) smi_config (except SetErrorHandler), most of smi_module (no Revision functions) and some of smi_node (no Element or Refinement functions). The advantage to hand-coding over SWIG is that the smi data structures are properly reflected in real python objects. With SWIG, a nodes smiValue reference becomes a string representation of a C pointer, providing no real value to the python programmer. By properly producing the return objects, the python Node object contains a "real" Value object that properly represents the equivalent C structure. First question: Is there a test suite anywhere that I can use to help generate a python test suite to verify that I'm not mucking up the results of the underlying smi calls? Second question: Is anyone else interested in a full Python wrapper? I'm no SMI expert (beyond SNMP MIB's using it), and I can't really pursue much more functionality since I'm basically clueless about Elements, Refinements, Types, and Macros. If there _is_ a test suite, I could implement based on that, if not I could use advice and suggestions on where to learn more so I can extend as time permits. If nobody else cares, I'll just keep it as is until I need more from it. TIA -- Mark W. Alexander slash(a)dotnetslash.net

Problem in Indexing Table..
by Vivekanandan V 30 Sep '02

30 Sep '02

Hi, In Rfc:2674 (P-BRIDGE MIB), an Table Object, which is having read-write access is later used as an Index for another Table. Is this Correct??? To be more precise, dot1dRegenUserPriority is an object of Dot1dUserPriorityRegenEntry, with read-write access. In later part of the mib, the same dot1dRegenUserPriority is used as an Index for the Table dot1dPortOutboundAccessPriorityTable. Libsmi is not giving any Warnings/Errors for this?? So can I assume that this is a correct usage?? But the tool we are using gives an error saying Index element should be not-accessible. So which is correct??

libsmi on Windows
by Henning Eggers 23 Sep '02

23 Sep '02

Hello, this is to anybody who works with smilib on Windows. I am trying to use libsmi-0.4.0 on WindowsNT. I am using VC6.0. The lib and my testing code compile with no problem but at run-time I see this assertion: ----------------------------------------------------- Debug Assertion Failed! Pogram: D:\projects\libsmitest\Debug\libsmitest.exe File: dbgheap.c Line: 1084 Expression: pHead->nBlockUse == nBlockUse ----------------------------------------------------- The code in question is: smiInit(NULL); smiSetPath("d:\\projects\\smi\\mibs\\ietf"); smiLoadModule("SNMPv2-SMI"); smiLoadModule("SNMPv2-TC"); smiLoadModule("SNMPv2-CONF"); smiLoadModule("SNMPv2-MIB"); The assertion gets fired on the last call to LoadModule. If I leave that call out, the program runs cleanly but doesn't do anything useful, of course. I saw a problem like this on this list in June but the answer was simply to call smiInit first which is the case with my code. Running the debugger shows that the error occurs when smiparse() gets called but this is what the call stack contains: _free_dbg(void * 0x00309630, int 2) line 1084 + 43 bytes __crtsetenv(const char * 0x0030aa90, const int 1) line 174 + 17 bytes LIBSMITEST! putenv + 54 bytes timegm(tm * 0x00000002) line 165 + 10 bytes mainCRTStartup() line 206 + 25 bytes KERNEL32! 77f1b9ea() Unfortunately I cannot trace into smiparse() because the debugger does not seem to be able to handle the flex/bison-code or it is simply not there. The whole thing does not happen on Linux (gcc)! Any help is appreciated! Henning

Hi, This thread seems to be getting a bit to long !!! But, I am sorry to say that the problem persists with the pre0.4.1 code that you sent me. It works fine with 0.3.1 though!!!

Hi, I tried with libsmi 0.3.1and the language is correctly identified as SMIv2 for this MIB so there seems to be a problem with that in 0.4.0. As I am behind a firewall, I cannot access the CVS code through my CVS client. Is there some other way that I can get the current snapshot of the CVS code ?

Frank> Are you sure? I get ``Language: SMIv2'' for this MIB. barora> Absolutely! [...] BTW, what are the parameters by which the barora> language is guessed ? Could you give a try to the current snapshot from CVS? Perhaps, there is a bug in 0.4.0 due to the new support for SPPI PIBs which introduced new language detection code. The code evolved a bit since then, and from the current code I cannot reproduce the problem of wrongly identified MIB languages. The detection is based on imports from certain SMI language specific modules and from constructs like MODULE-IDENTITY, etc. -frank -- !!

Hi, Try the -p option of smidump. It is used to preload some mibs that are are imported by the target MIB.
