Install SNMP on UNIX – *BSD – GNU/Linux

He Simple Network Management Protocol either SNMP (of the English Simple Network Management Protocol) is a protocol of the application layer which facilitates the exchange of management information between network devices. It allows administrators to monitor network performance, find and resolve network problems, and plan network growth.

The most commonly used SNMP versions are SNMP version 1 (SNMPv1) and SNMP version 2 (SNMPv2).

SNMP in its latest version (SNMPv3) has significant changes compared to its predecessors, especially in security aspects, however it has not been widely accepted in the industry.

make
make install
make clean

We add it so that it starts automatically

CODE

text

vi  /etc/rc.conf

And we add the following:

CODE

text

 snmpd_enable="YES"
snmpd_conffile="/usr/local/etc/snmpd.conf"

Configuration file: /usr/local/etc/snmpd.conf

We copy the template

CODE

Bash

cp /usr/local/share/snmp/snmpd.conf.example /usr/local/etc/snmpd.conf

Install on Solaris

CODE

text

./configure --with-mib-modules="ucd-snmp/lmSensors ucd-snmp/diskio \
      smux mibII/mta_sendmail" --with-cc=gcc

We compile and install

CODE

text

Make && make install

Configuration file: /etc/sma/snmp/snmpd.conf

We copy the configuration template

CODE

text

/etc/sma/snmp/snmpd.conf.dist  /etc/sma/snmp/snmpd.conf

From Source Code

We download net-snmp

BASH

Bash

wget http://sourceforge.net/projects/net-snmp/files/net-snmp/5.6.1.1/net-snmp-5.6.1.1.tar.gz

We decompress

CODE

Bash

tar xvf net-snmp-5.6.1.1.tar.gz

We access the folder

We configure…

CODE

Bash

./configure --with-default-snmp-version="3" --with-sys-contact="rokitoh@red-orbita.com" --with-sys-location="Unknown" --with-logfile="/var/log/snmpd.log" --with-persistent-directory="/var/net-snmp"

After a while something like this will appear
