ucs-snmp に関するインストールメモ(2002/07/20) 
 

ucd-snmpの設定方法

ucs-snmp ですが、2003/05現在というか新しい "net-snmp" という名称となっていますので、そちらをインストールすることをお勧めします。

1) 既存の snmpマネージャを起動しない様に、管理者メニューから snmpの起動を停止します。設定終了後、ps コマンドで snmpサービスが起動されていない事を確認してください。

2) ucd-snmp のインストールを行う。./configure をかけると、問いかけがあります。(時間かかります)

% cd ./src
% wget http://unc.dl.sourceforge.net/sourceforge/net-snmp/ucd-snmp-4.2.6.tar.gz
% gzip -cd ucd-snmp-4.2.6.tar.gz | tar xf -
% cd ucd-snmp-4.2.6
% ./configure 

   checking if you have run configure before...
   ************** Configuration Section **************

   You are about to be prompted with a series of questions. Answer
   them carefully, as they determine how the snmp agent and related
   applications are to function.

   After the configure script finishes, you can browse the newly
   created config.h file for further - less important - parameters to
   modify. Be careful if you re-run configure though, since config.h will
   be overwritten.

   -Press return to continue-  ←Enterを押します

   disabling above prompt for future runs... yes
   checking System Contact Information...

   *** System Contact Information:

   Describes who should be contacted about the host the agent is
   running on. This information is available in the MIB-II tree. This
   can also be over-ridden using the "syscontact" syntax in the agent's
   configuration files.

   System Contact Information (hoge@hoge.co.jp): ←管理者のメールアドレスを入力します
   setting System Contact Information to... hoge@hoge.co.jp
   checking System Location...

   *** System Location:

   Describes the location of the system. This information is
   available in the MIB-II tree. this can also be over-ridden using the
   "syslocation" syntax in the agent's configuration files.

   System Location (Unknown): Qube3J Server
   setting System Location to... Intel-Solaris8 Server
   checking Location to write logfile...


   *** Logfile location: 

   Enter the default location for the snmpd agent to dump
   information & errors to. If not defined (enter the keyword "none"
   at the prompt below) the agent will use stdout and stderr instead.
   (Note: This value can be over-ridden using command line options.)

   Location to write logfile (/var/log/snmpd.log): ←お好きな場所に♪
   setting Location to write logfile to... /var/log/snmpd.log
   checking Location to write persistent information...


   *** snmpd persistent storage location:

   Enter a directory for the snmp library to store persistent
   data in the form of a configuration file.

   Location to write persistent information (/var/ucd-snmp): ←こちらも (^o^)丿 な
   setting Location to write persistent information to... /var/ucd-snmp

3) コンパイルと動作テストをします。(すげー時間かかります)

% make
% make test
    Summary: 33 / 33 succeeded.   ←こう表示されれば ok ♪
    make[1]: Leaving directory `/home/hoge/src/ucd-snmp-4.2.6/testing'

4) インストールをするだす。

% su
# umask 022
# make install

5) ucd-snmpエージェントの起動前設定をします。

# cp EXAMPLE.conf /usr/local/share/snmp/snmpd.conf
# vi /usr/local/share/snmp/snmpd.conf
    変更点
    # sec.name source community
    com2sec local localhost PRIVATE
    com2sec mynetwork 192.xxx.xxx.xxx/24 HOME
    # Second, map the security names into group names:
    #group MyRWGroup v1 local
    #group MyRWGroup v2c local
    #group MyRWGroup usm local
    group MyROGroup v1 mynetwork
    group MyROGroup v2c mynetwork
    group MyROGroup usm mynetwork
    # It is also possible to set the sysContact and sysLocation system
    # variables through the snmpd.conf file:
    syslocation Intel-Solaris8 Unix Server
    syscontact Me <hoge@hoge.co.jp>
    # Make sure mountd is running
    #proc mountd
    # Make sure there are no more than 4 ntalkds running, but 0 is ok too.
    #proc ntalkd 4
    # Make sure at least one sendmail, but less than or equal to 10 are running.
    #proc sendmail 10 1
    # a simple hello world
    #exec echotest /bin/echo hello world
    # Check the / partition and make sure it contains at least 10 megs.
    disk / 497829
    disk /usr/local 2522048

6) ucd-snmpエージェントの起動をします。

# /usr/local/sbin/snmpd
# ps -ef | grep snmpd
    root 26880 26734  0 16:22:25 pts/2 0:00 grep -n snmpd
    root 26878     1  0 16:22:18 pts/2 0:00 /usr/local/sbin/snmpd

7) 動作チェックを行います。下のコマンドを実行し、山の様になんか帰ってくれば ok です。

# snmpwalk -v 1 SNMPエージェントのIPアドレス HOME .1.3.6.1.2.1 

8) 自動起動するように設定します。

# cd /etc/rc.d/init.d
# vi ucd-snmp
# chmod +x ucd-snmp
# cd /etc/rc.d/rc3.d
# ln -s /etc/rc.d/init.d/ucd-snmp S77ucd-snmp
