MIBs dynamically read or static? #76

Closed carlklatsky closed 1 year ago

carlklatsky commented 1 year ago

Hi,

Not sure if this is still an active project, but wanted to know if the MIB files in the ./mibs directory are dynamically read at file decode time or statically linked at compile time? I had thought they were dynamically read when the command is issued to decode a DOCSIS file, but it seems like it is not working for me. I am sure the MIB file to decode an SNMP OID into its name is in the ./mibs directory, but the decoded file still listed it by OID.

SnmpMibObject .1.3.6.1.2.1.69.1.2.1.2.1 IPAddress 0.0.0.0;
SnmpMibObject .1.3.6.1.2.1.69.1.2.1.3.1 IPAddress 0.0.0.0;

Do files added to the ./mibs directory need a specific file extension to be read in?

Thanks, Carl

The project is more or less inactive. I try to look at things occasionally, but I don't even use the utility myself.

Understood. I will dig into it some more when I have time, but marking this issue closed for now. Thanks.

Just an addendum on my findings. I am building under cygwin environment. When running autogen.sh, which I think also runs configure.sh, it seems like the mib path variable NETSNMP_MIBPATH in the Makefile in the main build directory is not getting set. I manually edited that variable to be NETSNMP_MIBPATH=$(CYGWIN_BUILDROOT)/mibs, which is where I added additional mib files. Then re-build which incorporates the MIBs in that file, then decode the file and this time the OIDs that were not decoded to name now are decoded to name.

And I think this answers my own question that the MIB files get linked statically at build time. New MIB files cannot just be dropped in the /mibs directory and expect to be available for decode.
