Isabelv5 Updates

2010-07-30T14:29:00.003-05:00

Informamos a todos los usuarios de ISABEL que después de algunos cambios internos y mejoras de sus componentes, se ha recortado el soporte a las distribuciones de Linux Ubuntu anteriores a 8.04 (Hardy Heron).
Por lo tanto se recomienda la actualización de la distribución de Ubuntu y la versión de Isabel la cual a la fecha es:
Last Version: Isabel- 4.12.beta14 -2

Existen dos procedimientos para mejorar la distribución Ubuntu para compatibilidad con Isabel:
Nota: Isabelv5 está basado en Ubuntu 9.10 (Karmic) y es compatible con Ubuntu 8.04, 8.10 y 9.04

1.- Descargar e instalar el último Ubuntu Live CD desde la web de Isabel Agora
2.- Actualizar la distribución de Ubuntu usando el update-manager. (Sistema > Gestor de Actualizaciones)

De igual modo el procedimiento para actualizar la version de Isabel es la siguiente:

1.- En el Ubuntu abrimos una Consola Terminal

2.- Nos dirijimos a el archivo ""sources.list" y lo editamos:

user@server:~$ sudo vim /etc/apt/sources.list

3.- Comentar la siguiente linea como sigue:

# Update Isabel from http://www.agora-2000.com/ubuntu/

4.- Agregar la siguiente linea: (NUEVO REPOSITORIO)

deb http://ubuntu.dit.upm.es/ karmic extras

5.- Guardar y salir

6.- Actualizar la version de ISABEL (Ir a "Aplicaciones" -> Isabel -> Utilities -> Isabel Update)

MIB2C and .c .h files

2010-05-12T11:27:00.001-05:00

Mib2c es un comando especializado en la producción de templates de codigo desde definiciones MIB.

El archivo generado *.c es un template de codigo fuente en C (instrucciones de programacion comprensible para un humano) en la cual se deben agregar algunas definiciones de forma detallada necesariamente antes de ser compiladas para implementar el modulo. (Module definition, Module initialization, Variable handling, Non-table-based modules, Simple Tables, General Tables, Set-able object). Este archivo *.c hace llamado al archivo *.h
El archivo generado *.h (headers) es un archivo cabecera de codigo fuente en C incluyendo los declaraciones de funciones.

Ejemplo:

1.- Verificar el directorio de MIBS:

wmunguiam@server:~$ cd /usr/local/share/snmp/mibs/

HOWTO use SNMPv3 (UBUNTU)

2009-07-04T12:30:00.005-05:00

HOWTO use SNMPv3 (UBUNTU)

1.- Install SNMP

Follow the follow blog entry to install SNMP server and client first.
http://wmunguiam.blogspot.com/2009/07/howto-install-snmp-and-test-snmpv1.html

2.- Level users
SNMP version 3 (SNMPv3) is used to provide a secured environment in managing the systems and networks. The SNMPv3 Agent provides support for three level of users. The supported security levels as defined in the USM MIB (RFC 2574) are:

noAuthNoPriv - Communication without authentication and privacy.
authNoPriv - Communication with authentication and without privacy. The protocols used for Authentication are MD5 and SHA (Secure Hash Algorithm).
authPriv - Communication with authentication and privacy. The protocols used for Authentication are MD5 and SHA. The DES (Data Encryption Standard) protocol is used for Privacy.

3.- MIB Tree:
Reference: http://www.alvestrand.no/objectid/1.3.6.1.2.1.html

1.3.6.1.2.1.1 - SNMP MIB-2 System
1.3.6.1.2.1.2 - SNMP MIB-2 Interfaces
1.3.6.1.2.1.3 - at
1.3.6.1.2.1.4 - ip
1.3.6.1.2.1.5 - icmp
1.3.6.1.2.1.6 - tcp
1.3.6.1.2.1.7 - udp
1.3.6.1.2.1.1.1 - sysDescr
1.3.6.1.2.1.1.2 - sysObjectID
1.3.6.1.2.1.1.3 - sysUpTime
1.3.6.1.2.1.1.4 - sysContact
1.3.6.1.2.1.1.5 - sysName
1.3.6.1.2.1.1.6 - sysLocation
1.3.6.1.2.1.1.7 - sysServices

4.- Backup "snmpd.conf" (to restore it if want later)

wmunguiam@server:~$ sudo mv /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf-backup

5.- Manual Edition of "snmpd.conf" for SNMPv3

Go to directory:

wmunguiam@server:~$ cd /etc/snmp/

Review files: (look for snmpd.conf)

wmunguiam@server:~$ ls -lh

Edit snmpd.conf:

wmunguiam@server:~$ sudo vim snmpd.conf

None of the pre-built vmmon modules for VMware Server is suitable for your
running kernel. Do you want this program to try to build the vmmon module for
your system (you need to have a C compiler installed on your system)? [yes]

Using compiler "/usr/bin/gcc". Use environment variable CC to override.

Your kernel was built with "gcc" version "4.2.3", while you are trying to use
"/usr/bin/gcc" version "4.2.4". This configuration is not recommended and
VMware Server may crash if you'll continue. Please try to use exactly same
compiler as one used for building your kernel. Do you want to go with compiler
"/usr/bin/gcc" version "4.2.4" anyway? [no] yes

What is the location of the directory of C header files that match your running
kernel? [/lib/modules/2.6.24-23-generic/build/include]

Updatedb and locate spine. My case: /usr/local/spine/etc

root@server:/var/www/noc/spine# cd /usr/local/spine/etc/
root@server:/usr/local/spine/etc# cp spine.conf.dist spine.conf
root@server:/usr/local/spine/etc# vim spine.conf

Change from:

DB_Host localhost
DB_Database cacti
DB_User cactiuser
DB_Pass cactiuser
DB_Port 3306

To:

DB_Host localhost
DB_Database cactidb
DB_User cactiuser
DB_Pass somepassword
DB_Port 3306

Remember that include/config.php is:

$database_type = "mysql";
$database_default = "cactidb";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "somepassword";
$database_port = "3306";

5.- Activate SPINE for cacti
This is the cacti Log before use spine (only with cmd.php)

Update spine binary location:

OBS If you receive some FAILED messages then PA won't work fine. I recommend you to Re-install cacti.

3.- Apply patches and fix some changes
Apply the Diff file

root@server:/var/www/cacti# patch -p1 -N < cacti-plugin-0.8.7c-PA-v2.3.diff

Now, If you go to Cacti Web site you will see something like this:

So, You have to go to include/global.php file and update like this:

root@server:/var/www/cacti# vim include/global.php

Change from:

$config['url_path'] = '/';

to:

$config['url_path'] = '/cacti';

Now Cacti console is fixed but we need to update cacti DB

4.- Update DataBase
Cacti DB works with 48 TABLES but it will use 52 whit PluginArchitecture

root@server:/var/www/cacti# cd pa/
root@server:/var/www/cacti/pa# mysql -uroot -pRootPasswd noc <>

TABLES:

plugin_hooks
plugin_db_changes
plugin_realms
plugin_config

5.- Update Realm Permissions for "admin"
Enable Plugin Management for admin user
Go to:
console-> User Management -> Select Admin -> Realm Permissions

root@server:/var/www# wget http://www.cacti.net/downloads/cacti-0.8.7c.tar.gz

2.- Structuring Cacti
Create a sub-directory to store cacti system
Directories: rra/ and log/ have to be owned by web manager

root@server:/var/www# tar -xzvf cacti-0.8.7c.tar.gz
root@server:/var/www# move cacti-0.8.7c noc
root@server:/var/www# chown -R www-data:www-data noc/
root@server:/var/www# cd noc/

3.- Structuring DataBase
Creation of DB and permissions could be done by using Phpmyadmin

root@server:/var/www/noc# mysqladmin -uroot -pRootPasswd create cactidb

Then you have to import cacti.sql (included in cacti downloaded package)

root@server:/var/www/noc# mysql -uroot -pRootPasswd cactidb <>

Create a User to manage/access cacti DB

root@server:/var/www/noc# adduser cactiuser
Añadiendo usuario 'cactiuser' ...
Agregando nuevo grupo `cactiuser' (1002) ...
Agregando nuevo usuario `cactiuser' (1002) con grupo `cactiuser' ...
Creando el directorio personal '/home/cactiuser' ...
Copiando archivos desde '/etc/skel' ...
Introduzca la nueva contraseña de UNIX: somepassword
Vuelva a escribir la nueva contraseña de UNIX: somepassword
passwd: contraseña actualizada correctamente
Cambiando la información de usuario para cactiuser
Introduzca el nuevo valor, o presione ENTER para el predeterminado
Nombre completo []: Cacti Manager
Número de habitación []:
Teléfono del trabajo []:
Teléfono de casa []:
Otro []:
¿Es correcta la información? [y/N] y

And now we have to setup permissions in mysql

root@server:/var/www/noc# mysql -uroot -pRootPasswd
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 50
Server version: 5.0.51a-3ubuntu5.4 (Ubuntu)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> GRANT ALL ON cactidb.* TO cactiuser@localhost IDENTIFIED BY 'somepassword';
Query OK, 0 rows affected (0.04 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> quit
Bye
root@server:/var/www/noc#

4.- Setup Cacti config files
Edit include/config.php with data

root@server:/var/www/noc# cd include/
root@server:/var/www/noc/include# vim config.php

Edit include/config.php as follow:

$database_type = "mysql";
$database_default = "cactidb";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "somepassword";
$database_port = "3306";

Save and exit: ESC -> :wq

5.- Setup CRONTAB
Edit /etc/crontab

root@server:/var/www/noc/include# vim /etc/crontab

Add folowing line (According to my configuration)

*/5 * * * * cactiuser php /var/www/cacti/poller.php > /dev/null 2>&1

6.- Go to Web
Go to:

http://localhost/cacti/

You will be redirected to:
