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.

More malformed patterns using -f xsd
by Arndt Jonasson 13 Sep '06

13 Sep '06

I use libsmi 0.4.5. When I have a textual convention like this one: 1) NiceString1 ::= TEXTUAL-CONVENTION DISPLAY-HINT "2d" STATUS current DESCRIPTION "doc" SYNTAX OCTET STRING (SIZE (2)) the pattern which "dumpsmi -f xsd" translates the display hint into is: ((0|[1-9]([0-9]{0,5})) which has unbalanced parentheses. I think that line 655 smiAsprintf( &ret, "%s(0|[1-9]([0-9]{0,%d})", should be smiAsprintf( &ret, "%s(0|[1-9]([0-9]{0,%d}))", 2) Similar problem here: NiceString2 ::= TEXTUAL-CONVENTION DISPLAY-HINT "4d" STATUS current DESCRIPTION "doc" SYNTAX OCTET STRING (SIZE (0..2 | 4..5)) The pattern: (((0|[1-9]([0-9]{0,5}))|((0|[1-9]([0-9]{0,10}))) I think that line 726 if( ! lengths[ i - 2 ] ) { should be if( ! lengths[0] ) { (The fix from problem 2 is needed too here.) 3) A third problem with patterns from display hints is that a period (.) is not always escaped with a backslash (\.) (for example with the display hint "1x."). My suggested fix is to use a two-character char array for 'separator', and insert the '\' already when the separator is set from the hint. Then no tests are needed further down, but the %c changed to %s.

Ask for some basic usages about Libsmi smidump perl format
by wanderchiou 21 Aug '06

Hello, Everyone: I want to SNMP Testing tools to do SNMP conformance test. It needs to use Perl to send the basic/correct SNMP Get, GetNext, GetBulk Messages and create an wrong SNMP Get, GetNext, GetBulk Messages with incorrect fields in SNMP Messages to test SNMP Aget. I need a Perl-based MIB Compiler and MIB Browser(better) to read SMIv1 and SM1v2 syntax. Do you have any suggestions? I am surveying some Perl SNMP tools. (1) Libsmi I know that "libsmi smidump -p 'preload module' -f perl moules" can create Perl format. How to use the Perl format file? Do you have a Perl example to use it or have a document to describe the Perl format? How to integrate into Net-SNMP Perl Module? Is it possible? I note that '-p module' can preload only one module. May I preload many modules in advance? (2) Net-SNMP Perl Module It can send correct SNMP Message only and NetSNMP binary library. It can not send the incorrect SNMP Message and the wrong fields in SNMP Message. Do you know any Perl Package to sen SNMP Msg in Perl only without any additional library installation? Just use Perl Socket or Socket6 to create SNMP Header and SNMP PDU to send get, getnext, getbulk SNMP msgs. (3)How about Net::SNMP? http://search.cpan.org/dist/Net-SNMP/ How to integrate into Net::SNMP? Is it possible? Thank you very much in advance!
