Win32 app refuses to link with libsmi.a 0.4.5
by Pete Wilson 13 Sep '07

13 Sep '07

Hello everyone -- I'm new to libsmi, so please be patient with my perhaps-naive questions. I'm a C-language agent developer. I wrote a Win32 app called SimpleNMS that I use for agent testing: http://www.pwilson.net/SimpleNMSUserGuide.html I had hoped to use Win32 libsmi.a 0.4.5 in this app to map numeric OIDs to MIB names. But I can't so far link SimpleNMS with libsmi under MS VC++6.0 or VS 2005: the linker complains that it can't find _alloca(). I haven't found an easy fix yet: VS deprecates _alloca(); yet I can't replace it because it's intrinsic. And I haven't dared to build libsmi under VS from scratch. So my questions: 1. Is there a libsmi.a around that has actually worked with MS dev tools? 2. I get the impression that most libsmi dev is going on under 'nix and that that Win32 libsmi is pretty much an orphan child. If that's true, I'd be glad to volunteer as a foster parent to help with Win32 development. Can I be useful to list subscribers and libsmi users? Thanks very much, folks. I appreciate your help. I'm at a Catch-22 dead end and need to get past it. -- Pete Wilson ____________________________________________________________________________________ Pinpoint customers who are looking for what you sell. http://searchmarketing.yahoo.com/

How do I get the size of an OBJECT STRING?
by Luis EG Ontanon 26 Aug '07

26 Aug '07

Hi, I'm in a "quest" to rewrite Wireshark's snmp dissector with the goals of improving "filterability" of snmp packets (at the same time we'll get rid of the net-snmp dependecy that depends on open-ssl whose license isn't GPL compatible). I believe being able to filter on indexes of conceptual tables is far more interesting that to filter on any given value of an object's instance. I already implemented extracting the integer based indexes and (to some degree) those based on implicit octet strings but I got stuck on fixed-length strings. I haven't been able to figure out how to obtain the fixed length of a non-implied object string index element given: elNode = smiGetElementNode(smiElementPtr) && elType = smiGetNodeType(elNode) && elType->basetype == SMI_BASETYPE_OCTETSTRING Any help would be welcome.

lib/parser-smi.c (and other generated files) in svn tree
by Luis EG Ontanon 22 Aug '07

Hi, When doing a svn diff on the tree to generate a patch I found out that lib/parser-smi.c was actually checked in svn. Shouldn't generated files being kept outside of the svn repo? Luis -- This information is top security. When you have read it, destroy yourself. -- Marshall McLuhan

Re-distributing the MIBs collection
by Luis EG Ontanon 22 Aug '07

22 Aug '07

I'm on the process of rewriting Wireshark's snmp and most probably we'll be using libsmi. We would like to distribute libsmi's collection of MIBs along wireshark, can we? Thanks, Luis -- This information is top security. When you have read it, destroy yourself. -- Marshall McLuhan

Malformed XML from RFC1158-MIB and coredump converting RMON2-MIB
by Altaf Aali 08 Jun '07

08 Jun '07

I am having trouble trying to generate XML from the RFC1155 and RMON2 mibs using the following command lines on Solaris, respectively: smidump -f xml -p./RFC1155-SMI -oRFC1158-MIB.xml ./RFC1158-MIB smidump -f xml -p./SNMPv2-SMI -p./SNMPv2-TC -p./SNMPv2-CONF -p./ifmib.mib -p./TOKEN-RING-RMON-MIB -p./RMON-MIB -oRMON2-MIB.xml ./RMON2-MIB The first results in a malformed XML with mismatched tags. The second one results in a coredump every time. A pstack of one of the core dumps is as follows: ff3283b0 findNodeByParentAndSubid (ffbff1d0, 1, 0, b0860, 0, ff38d94c) + 54 ff339500 smiparse (ffbfefd2, 1, 1, ffbff1d0, ffbfef90, 400) + 59d4 ff329e84 loadModule (ffbff56f, 0, 94184, 76c00, ff2e8284, ff2f09b0) + 400 ff32f254 smiLoadModule (ffbff56f, 2, 75ed0, ffbff561, 0, 74c00) + 40 00012d14 main (0, ffbff364, 76c00, 771ac, ff3a00c0, ff3a0100) + 2a8 000121a8 _start (0, 0, 0, 0, 0, 0) + 5c Any help would be appreciated. Note that these MIBs are used from the mibs/ietf folder of the libsmi distribution. Thanks Altaf

Dumping base-types
by Altaf Aali 03 Jun '07

03 Jun '07

Hi all: First of all, I would like to mention that libsmi and the related tools are great products. I have a couple of questions: 1. Has anyone successfully built the libsmi package on Solaris 9/10. I have tried on Solaris 10 with no success; Configure works but the compilation fails almost immediately. I will soon try with Solaris 9 as well but any pointers would be really appreciated. 2. I would like to modify the 'dump identifers' driver for smidump to show the nodes in the following format: name oid syntax/base type I see that the names and oids are already dumped. However, instead of the syntax, the node type is dumped. I looked at the xml driver and saw that the base type was dumped in some cases but not all; instead, the syntax would point to a type module and then the name. I have added the imported modules as follows to the smidump.conf file: load dependency.mib load SNMPv2-TC load SNMPv2-CONF but still see the same output format. Here are a few examples of this: For myId column, I see the desired result: *-* <file:///D:/smi/mibs/fsvcm.mib.xml#> - <column name="myId" oid=" 1.3.6.1.4.1.2076.93.1.2.1.1" status="current"> - <syntax> - <typedef basetype="Integer32" name="" status="current"> <range min="0" max="65535" /> </typedef> </syntax> HHowever, for myMac, I see the pointer to the SNMP-TC mib: - <column name="myMac" oid="1.3.6.1.4.1.2076.93.1.2.1.3" status="current"> - <syntax> <type module="SNMPv2-TC" name="MacAddress" /> </syntax> Is there a way to get the base type or typedef for such columns. Any help would be greatly appreciated. Thanks Altaf I

Re: Libsmi Digest, Vol 24, Issue 1
by Jae Muzzin 13 Apr '07

Ok, the thing is though, we have a few hundred commercial MIBs to import, many of them throw errors. I won't argue the validity of their syntax, but net-snmp has no problem parsing them, and that is what we currently use. Is there some way to configure libsmi to be less strict with its parsing, or skip imports or definitions that have errors?

libsmi not parsing MIB
by Jae Muzzin 12 Apr '07

12 Apr '07

Hello, I'm using PYSNMP which uses smidump to convert MIBs into python modules. I have a MIB from a manufacturer, which works with net-snmp, but smidump throws a parsing error. Any ideas? Here is the error: /usr/local/share/mibs/site/enviromux-mini.mib:7: parse error, unexpected DISPLAY_HINT And here is the part of the mib that is throwing the error: NETWORK-TECHNOLOGIES-GLOBAL-REG DEFINITIONS ::= BEGIN IMPORTS MODULE-IDENTITY, OBJECT-TYPE, OBJECT-IDENTITY, enterprises FROM SNMPv2-SMI DisplayString, TEXTUAL-CONVENTION, DISPLAY-HINT FROM SNMPv2-TC; -- Jae Muzzin Netmon Technical Support jae(a)netmon.ca 1-800-944-4511 ext 223

libsmi reporting parse error, expecting '$'
by Juergen Schoenwaelder 21 Mar '07

21 Mar '07

Folks, I was getting this error IF-MIB:1: parse error, expecting `$' on several differnt platforms and it finally turned out to be an issue with bison/flex. I do not know the details, but I do know that the combination bison 1.875d and flex 2.5.31 does not work while the combination bison 2.1 and flex 2.5.4 seems to be fine. So if someone runs into similar trouble, make sure you upgrade your build tools... /js -- Juergen Schoenwaelder International University Bremen <http://www.eecs.iu-bremen.de/> P.O.
