SNMP on OpenSolaris 2008.11

Apparently there isn't any SNMP service daemon available in the OpenSolaris

# uname -a
SunOS opensolaris 5.11 snv_101b i86pc i386 i86pc Solaris

# svcs -a | grep -i snmp
disabled       22:28:58 svc:/network/device-discovery/printers:snmp

If you want to explore SNMP, you may want to download the Net-SNMP. In my case, I downloaded the source code for net-snmp-5.4.2.1 and configured & compiled with the default settings. BTW, I installed the SunStudio Express via the OpenSolaris Package Manager. The default location will be in /usr/local

# which cc
/usr/bin/cc

# ls -l /usr/bin/cc
lrwxrwxrwx 1 root root 33 2008-12-04 09:09 /usr/bin/cc -> ../../opt/SunStudioExpress/bin/cc

# cc -V
cc: Sun Ceres C 5.10 SunOS_i386 2008/10/22
usage: cc [ options] files.  Use 'cc -flags' for details

# CC=cc

# export CC/stdin>

# ./configure
....

# make
...

# make install

You need to configure it with /usr/local/bin/snmpconf -g basic_setup for basic configuration. Simply answer a dozen of questions and the software will create snmpd.conf file. Now all you have to do is to launch the snmpd daemon with this configuration file.
/usr/local/sbin/snmpd -c /usr/local/etc/snmpd.conf
Below shows you how you can explore the SNMP MIB information. I am using based on version 2c of the SNMP. You can get individual MIB data (eg. sysDesrc.0 - system description), recursively get the SNMP tree on the system, interface (if) or even the entire mib-2 section of the MIB-2 tree. BTW, my opensolaris is running in my VirtualBox
