SNMPD のインストール†

# cd /usr/ports/net-mgmt/net-snmp/
# make install
**** This port installs snmp daemon, header files and libraries but don't
    invokes snmpd by default.
    If you want to invoke snmpd and/or snmptrapd at startup, put these
    lines into /etc/rc.conf.

       snmpd_enable="YES"
       snmpd_flags="-a -p /var/run/snmpd.pid"
       snmptrapd_enable="YES"
       snmptrapd_flags="-a -p /var/run/snmptrapd.pid"

**** You may specify the following make variables:

       NET_SNMP_SYS_CONTACT="kuriyama@FreeBSD.org"
       NET_SNMP_SYS_LOCATION="Tokyo, Japan"
       DEFAULT_SNMP_VERSION=3
       NET_SNMP_MIB_MODULES="host smux mibII/mta_sendmail ucd-snmp/diskio"
       NET_SNMP_LOGFILE=/var/log/snmpd.log
       NET_SNMP_PERSISTENTDIR=/var/net-snmp

    to define default values (or overwriting defaults).  At least
    setting first two variables, you will not be prompted during
    configuration process.  You may also set

       BATCH="yes"

    to avoid interactive configuration.
