What version of libsmi does Ubuntu have? The current one is 0.4.8, but I
tend to use the one in Subversion.
Todd> According to "About Wireshark", it using SMI 0.4.8 ...
Are your MIBs ones that come with Ubuntu, some other package, or the
ones from libsmi? libsmi's parser is extremely strict and many other
sources have less than perfect (to be polite) syntax and semantics.
Frank and Juergen fix the MIBs they include in libsmi so they are correct.
Todd> Not sure exactly, possibly with Ubuntu, how do I determine this?
Todd> Notes:
* there are some mibs in directories /var/lib/mibs/iana and /var/lib/mibs/ietf File /etc/smi.conf "path" points to /usr/share/mibs/ which have symbolic links to the ones in /var/lib/mibs ...
* I did purge of the smi library(s), but these mibs were left in place " sudo apt-get purge libsmi2-common libsmi2-dev libsmi2ldbl", so ... (technically they should be removed if they were part of this install, no?), so this might be part of Ubuntu or ?
* I removed my wireshark configuration for SMI Path and SMI modules I added, but still get error " Stopped processing module RFC1213-MIB due to error(s) to prevent potential crash in libsmi." ...
* I then moved /var/lib/mibs/ietf/RFC1213-MIB somewhere else, then started wireshark again and got the same RFC1212-MIB, thus Wireshark must not be using this directory (/etc/smi.conf path points to them via sym-links in /usr/share/mibs/...
Todd> If Frank/Juergen fixed the mibs, where are the put when you install the libsmi?
If you want to include other MIBs you really have to make sure you have
all the IMPORTS, and that smilint accepts all the MIBs as valid with the
"-l 3" option at a minimum. "-l 4" would be better.
Todd> If can get base to work, I look into using private mibs and work through smilint, etc., I'm a newbie and part of my issue are finger issues right now...
Despite the fact that libsmi runs perfectly on 64 bit Unix systems I
have not managed to get it to compile for 64 bit Windows. Now there is a
64 bit box in the house I might give it another try so i can have a 64
bit Wireshark that does SNMP decodes.
