SNMP Install

SNMP Installation

Installing net-snmp on LINUX 390 systems.

1) Net-snmp is available from:

       http://net-snmp.sourceforge.net

2) Download ucd-snmp-4.2.1.tar.gz (or a later version when available) to your LINUX system root directory.

3) Unpack the zipped tar file using:

   tar  xzfv ucd-snmp-4.2.1.tar.gz
   cd /ucd-snmp-4.2.1

4) Add 390 support to config.sub and config.guess

   In config.sub after lines:                                            ;;
 
      i370-ibm* | ibm*)
           basic_machine=i370-ibm
           os=-mvs
           ;;
 
   Add these lines:
 
      s390-ibm)
           basic_machine=s390-ibm
           os=-linux-gnu
           ;;
 
   In config.guess after line:
 
   elf32ppc)   echo "powerpc-unknown-linux-gnu"              ; exit 0 ;;
 
   Add this line:
 
   elf_s390)   echo "s390-ibm-linux-gnu"                     ; exit 0 ;;

5) Configure the package to include the host MIB support.

   ./configure --with-mib-modules=host

6) Generate the package:

   make

7) Install the runtime components:

   make install

8) Add an snmpd shell script to /etc/rc.d/init.d as follows:

  #!/bin/bash
 
  # ucd-snmp init file for snmpd
  #
  # chkconfig: - 50 50
  # description: Simple Network Management Protocol (SNMP) Daemon
  #
  # processname: /usr/local/sbin/snmpd
  # config: /etc/snmp/snmpd.conf
  # config: /usr/share/snmp/snmpd.conf
  # pidfile: /var/run/snmpd
 
  # source function library
  . /etc/rc.d/init.d/functions
 
  OPTIONS="-s -l /dev/null -P /var/run/snmpd -a"
  RETVAL=0
 
  start() {
      echo -n "Starting snmpd: "
          daemon /usr/local/sbin/snmpd $OPTIONS
      RETVAL=$?
      echo
      touch /var/lock/subsys/snmpd
      return $RETVAL
  }
 
  stop() {
      echo -n "Shutting down snmpd: "
      killproc /usr/local/sbin/snmpd
      RETVAL=$?
      echo
      rm -f /var/lock/subsys/snmpd
      return $RETVAL
  }
 
  reload(){
      start
      stop
  }
 
  restart(){
      start
      stop
  }
 
  condrestart(){
      [ -e /var/lock/subsys/snmpd ] && restart
      return 0
  }
 
  case "$1" in
    start)
      start
      ;;
    stop)
      stop
      ;;
    restart)
      restart
          ;;
    reload)
      reload
          ;;
    condrestart)
      condrestart
      ;;
    status)
          status snmpd
          ;;
    *)
      echo "Usage: snmpd {start|stop|status|restart|condrestart|reload}"
      RETVAL=1
  esac
 
  exit $RETVAL

9) Configure your system to start the snmp deamon during system startup. Issue these commands from root:

   cd /etc/rc.d/rc3.d
   ln -s ../init.d/snmpd S99snmpd
   cd /etc/rc.d/rc5.d
   ln -s ../init.d/snmpd S99snmpd
   cd /etc/rc.d/rc6.d
   ln -s ../init.d/snmpd K00snmpd

10) Manually start or stop the snmp deamon if necessary:

   /etc/rc.d/init.d/snmpd start
 
   /etc/rc.d/init.d/snmpd stop
