Hits: 504

SNMP, atau Simple Network Management Protocol, banyak digunakan untuk berkomunikasi dan memantau perangkat jaringan, seperti router, server, switch dan yang lainnya.

Kali ini, kita akan memasang atau menginstall serta mengkonfigurasi SNMP Agent di server dengan Sistem Operasi linux CentOS, ikuti langkah-langkahnya sebagai berikut:

  1. Install SNMP

    [root@ns1 ~]# yum install net-snmp net-snmp-utils -y
  1. Konfigurasi SNMP

    [root@ns1 ~]# cd /etc/snmp
[root@ns1 snmp]# cp snmpd.conf snmpd.conf.ori

    [root@ns1 snmp]# nano snmpd.conf

####
# First, map the community name "public" into a "security name"

#       sec.name  source          community
#com2sec notConfigUser  default       public
com2sec notConfigUser  default       public@MySNMP

####
#
####
# Third, create a view for us to let the group have rights to:

# Make at least  snmpwalk -v 1 localhost -c public system fast again.
#       name           incl/excl     subtree         mask(optional)
view    systemview    included   .1.3.6.1.2.1.1
view    systemview    included   .1.3.6.1.2.1.25.1.1
view    all    included   .1

####
#
####
# Finally, grant the group read-only access to the systemview view.

#       group          context sec.model sec.level prefix read   write  notif
# access  notConfigGroup ""      any       noauth    exact  systemview none none
access  notConfigGroup ""        any       noauth    exact  all none none

# -----------------------------------------------------------------------------

# YOU SHOULD CHANGE THE "COMMUNITY" TOKEN BELOW TO A NEW KEYWORD ONLY
# KNOWN AT YOUR SITE.  YOU *MUST* CHANGE THE NETWORK TOKEN BELOW TO
# SOMETHING REFLECTING YOUR LOCAL NETWORK ADDRESS SPACE.

##       sec.name  source          community
#com2sec local     localhost       COMMUNITY
#com2sec mynetwork NETWORK/24      COMMUNITY
com2sec local     localhost      public@MySNMP
com2sec mynetwork 0.0.0.0/0      public@MySNMP

##     group.name sec.model  sec.name

# System contact information
#

# It is also possible to set the sysContact and sysLocation system
# variables through the snmpd.conf file:

#syslocation Unknown (edit /etc/snmp/snmpd.conf)
#syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf)
syslocation SMKN 1 Klaten

  1. Konfigurasi firewall

    [root@ns1 snmp]# firewall-cmd --permanent --add-port=161/udp
[root@ns1 snmp]# firewall-cmd --reload
[root@ns1 snmp]# firewall-cmd --list-all
public (active)
  target: default
  icmp-block-inversion: no
  interfaces: eno1
  sources:
  services: cpanel dhcpv6-client ssh
  ports: 161/udp
  protocols:
  masquerade: no
  forward-ports:
  source-ports:
  icmp-blocks:

  1. Pengujian

    [root@ns1 snmp]# service snmpd start
[root@ns1 snmp]# systemctl enable snmpd
[root@ns1 snmp]# snmpwalk -v 2c -c public@MySNMP -O e localhost
