Anonymous CVS Server not available
by Frank Strauss 04 Aug '03

04 Aug '03

Hi! Due to a breakin into our anonymous CVS server which usually makes read-only modules for the "scotty", "scli", and "libsmi" projects available, we had to stop this service for the time being. Since the attacker gained shell access and since we don't know enough details about the underlying vulnerability, we cannot estimate when this security problem will be fixed and the CVS repository will be online again. Until then, I've setup a nightly cron job that puts tarballs of freshly checked out CVS modules to the following places: ftp://ftp.ibr.cs.tu-bs.de/local/scotty/scotty-cvs-snapshot.tar.gz ftp://ftp.ibr.cs.tu-bs.de/local/scli/scli-cvs-snapshot.tar.gz ftp://ftp.ibr.cs.tu-bs.de/local/libsmi/libsmi-cvs-snapshot.tar.gz -frank

Problem solved!
by Garth R Conrad 02 Jul '03

02 Jul '03

I figured out the problem that was causing my SNMP-COMMUNITY-MIB to not get loaded via a load statement in my .smirc file. The previous load statement was telling libsmi to load a module that contained a couple of syntax errors, which was probably putting libsmi into a messed up state. When I fixed the syntax errors in the previous MIB module, the problem went away, and now the SNMP-COMMUNITY-MIB is being properly loaded. Thanks, Garth Conrad garthc(a)us.ibm.com

Strange behavior when loading a module
by Garth R Conrad 02 Jul '03

02 Jul '03

Hi, I'm seeing some unexpected behavior in libsmi 0.4.1. I'm using a .smirc config file that contains one "level" statement, one "path" statement, then a big section of about 45 or 50 "load" statements. One of the load statements is: load SNMP-COMMUNITY-MIB I do have a file by that name in the search path, and I've verified that its syntax is OK by using smilint. Now when I run the following code: smiInit(); /* some code omitted here */ node = smiGetNode(NULL,"snmpCommunityMIB"); then node is NULL, i.e. libsmi can't seem to find the node named snmpCommunityMIB even though it's defined in my SNMP-COMMUNITY-MIB. In fact, libsmi can't find any of the nodes defined in SNMP-COMMUNITY-MIB. BUT... if I comment out all of the other load statements from my .smirc file except the one that loads SNMP-COMMUNITY-MIB, then when my code runs, libsmi seems to be able to find the node snmpCommunityMIB, because the variable "node" is not NULL. In fact, libsmi is able to find all of the nodes defined in SNMP-COMMUNITY-MIB. Is this a libsmi bug? If not, any ideas what could be causing it and how I can fix it? I need to load all of my MIB modules, so it's not acceptable for me to leave the other load statements commented out. Thanks, Garth Conrad garthc(a)us.ibm.com

libsmi for win32
by Juergen Schoenwaelder 18 Jun '03

18 Jun '03

I compiled Win32 executables from the current CVS version using mingw and I have packaged everything into a zip archive: http://www.ibr.cs.tu-bs.de/~schoenw/libsmi-mingw.zip Ignorant as I am, the installation assumes that you unpack it under C: (I guess the Windows term for this is `drive' but I am not even sure). If this works for you, be happy. If you have a question, better ask your mother since she probably knows more about Windows than I do. ;-) /js

Unsigned64 Errors
by Rajbal Balan 17 Jun '03

17 Jun '03

Hi, I just inherited some scripts which use the SMI tools (smilint, smidump) and am pretty new to this. So if this question is basic, pl excuse me; I have already searched the archives ... When checking a set MIB modules using smilint, I get the following errors- [...snip...] nortelPC-standardTextualConventionsV1_CC0066B.mib:42: [1] {} type `Gauge32' may only be defined in SMI/SPPI base modules nortelPC-standardTextualConventionsV1_CC0066B.mib:43: [1] {} type `Counter32' may only be defined in SMI/SPPI base modules nortelPC-standardTextualConventionsV1_CC0066B.mib:44: [1] {} type `Unsigned32' may only be defined in SMI/SPPI base modules nortelPC-standardTextualConventionsV1_CC0066B.mib:45: [1] {} type `Integer32' may only be defined in SMI/SPPI base modules nortelPC-textualConventionsV1_CC0066B.mib:57: [1] {} type `Unsigned64' may only be defined in SMI/SPPI base modules nortelPC-textualConventionsV1_CC0066B.mib:194: [2] {enum-zero} number enumeration contains zero value in SMIv1 MIB nortelPC-frameRelayUniV1_CC0066B.mib:36: [0] {} the SPPI construct/keyword `Unsigned64' may not be used in a MIB [end] How do I define/setup a base module (since that seems to be core of the problem)? Is there anything else I am missing?

The user just selects the MIB files he wants to load, I don't know those files in advance so I can't do the mapping. But I'm becoming evil and I'll change the filenames as they are loaded :D. Btw, besides filenames without extensions on win32 does libsmi recognize other MIB extensions for autoload? Like : .my, .mib, etc. > I think this is a good project for someone who wants to learn more > about the libsmi internals. ;-) The autoload for the above standard extensions would be a much more interesting/needed project (well, needed for me), if not done already :). > /js > -- > !!
