Well, yes that would be the tool, but things are more complicated. BSNMP uses a special file format (the .def files) to automatically create some tables and #defines when you implement a MIB. If you invent your own MIB, you normally write the .def file from scratch. It basically contains the same info as the MIB file, but in a less baroque and more machine-parsable format. If you're going to implement a MIB for which you already have a MIB file you can shorten the time to write the .def file by feeding the MIB file into gensnmpdef. It will create you an initial .def file, which, in most cases, you have to edit, though. But having the .def file is only the start of implementing. Because then you must write the action routines that actually implement the MIB behaviour. You might look under /usr/src/contrib/bsnmp/snmp_mibII. Here you find an example .def file the contents of which you might find familiar. The .c files there implement the semantic of the standard MIB-2. gensnmpdef is not built automatically, because it requires libsmi which you need to install from ports. This explains much about what I was confused with. Thank you for the quick response. It was fairly simple to get the port installed and get /usr/src/contrib/bsnmp/gensnmpdef compiled and installed. From there I went and built my ucd_tree.def file using gensnmpdef which I had to edit as you said. I see after doing this and looking into the examples you suggested this would be a bit more involved then I initially thought. I was able to generate some .c/.h files using gensnmptree but from there the legwork goes beyond me a bit. Looks like I have to look into this deeper. I do have one remaining question. How is the gensnmptree -l command used exactly? Something like cat ucd_tree.c | gensnmptree -l ? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

FreeBSD 6.2 + my gensnmptree issue
I am having an issue which is most likely my lack of understanding and not a problem with 6.2 itself. The system is running 6.2-RELEASE and I use bsnmpd. Here is the uname output. FreeBSD lucky.orisit 6.2-RELEASE FreeBSD 6.2-RELEASE #0: Wed Oct 10 10:40:51 EDT 2007 What I am trying to do is get bsnmp to respond to new MIBs, specifically UCD-SNMP-MIB. After reading the manpages for bsnmp and gensnmptree I believe gensnmptree is the command I need to use. This is where I get into trouble. The gensnmptree command doesn't give me any results no matter what I do. Even using a bug report example of gensnmptree -e sysName gives me no results. So I proceeded to do some more google searching and noticed gensnmpdef was referenced several times as the program which may be what I need to use. I found the code for this in /usr/src/contrib/bsnmp/gensnmpdef without a makefile. There is no gensnmpdef in /usr/sbin on the system but it is in the /usr/ports/net-mgt/bsnmpd/pkg-plist. So I guess I need some guidance. Can I use gensnmptree to get this MIB into the bsnmp system? If so how is this done? -or- Is there a problem with the 6.2 release for gensnmpdef and that is in fact the program I am suppose to be using? Any assistance would be appreciated.
