Re: Merging Joel Knight's SNMP MIB into net/net-snmp

["Brian A. Seklecki" <lavalamp%spiritual-machines.org@localhost>]

All:

Just revisiting this.  The yamt-pf42 patch was merged into
NetBSD-current recently and appears to have all of the pfSync data
structures (correct me if I'm wrong), making it significantly easier to
merge Joel Knight's PF-MIB patches into our net/net-snmp/ 

Any change of getting his files added to pkgsrc/ before NetBSD 5.0
branches?

All:

The PF-MIB patches compile against the Net-SNMP in Pkgsrc with a little
help (pfSync is missing).

The patch to r1.67 of pkgsrc/net/net-snmp/Makefile is here:
http://people.collaborativefusion.com/~seklecki/pkgsrc_netsnmp541_OBSD_pfMIB.patch

1) Untar the obsd-mibs42.tar
2) copy files/* into pkgsrc/net/net-snmp/files
3) Download the patch && patch -p0 < pkgsrc_netsnmp541_OBSD_pfMIB.patch
4) make extract
5) Manually adjust work/net-snmp-5.4.1/mibs/Makefile.in
6) make build (it will fail in work/net-snmp/local/ due 
   to USE_TOOLS=PERL)
7) cd work/net-snmp-5.4.1/local/ && make -k && cd -
8) make package

Example Output:

lavalamp@nbsdbuild-i386-netbsd4:/usr/pkgsrc/net/net-snmp# snmpwalk -v2c\
 -c netbsd localhost OPENBSD-CARP-MIB::carpIfTable

 OPENBSD-CARP-MIB::carpIfIndex.1 = INTEGER: 1
 OPENBSD-CARP-MIB::carpIfDescr.1 = STRING: "carp100"
 OPENBSD-CARP-MIB::carpIfVhid.1 = INTEGER: -1
 OPENBSD-CARP-MIB::carpIfDev.1 = ""
 OPENBSD-CARP-MIB::carpIfAdvbase.1 = INTEGER: 1
 OPENBSD-CARP-MIB::carpIfAdvskew.1 = INTEGER: 0
 OPENBSD-CARP-MIB::carpIfState.1 = INTEGER: init(0)

PS: 
It also has the added benefit of killing the dependency on Perl
run/build dependency :)
