[editar]
funciones implementadas con samba.-
- hosting de archivos
- compartir archivos, carpetas y recursos
- gestión centralizada de usuarios windows mediante la integracíón Samba-OpenLDAP
[editar]
servidores con samba en producción.-
aaa
.- mantiene el hosting de archivos de los departamentos, proporcionando un recurso compartido a cada servicio o grupo de trabajo. .- la gestión de usuarios la realiza el sistema operativo de este servidor vía archivo /etc/passwd .- las copias de seguridad de las carpetas de los servicios se realiza mediante sincronización con los discos SCSI de bbb (rsync), distribuyendo cinco copias a la semana entre dos discos diferentes en cinco carpetas (1=lunes, 2=martes, ...)
este es el código que ejecuta el archivo istambul:/home/admin/lmxjv.sh variando segun la fecha la carpeta y disco de destino: rsync -auvzr --progress root@aaa.dominio.es:/origen/* /destino/...
bbb
.- mantiene un servidor samba en entorno de desarrollo especialmente para las pruebas de integración samba-ldap; fue el primer servidor samba cuyo sistema de usuarios se apuntaba al servidor ldap
ccc
.- este equipo mantiene el árbol ldap de la organización, de donde partirá la unificación de usuarios; mantiene también un servidor samba como el de bbb con gestión de usuarios vía ldap
[editar]
implementación.-
para servidores con gestión local de usuarios
apt-get install samba samba-common
para servidores con gestion de usuarios ldap además
apt-get install smbldap-tools
el resto es activar el tipo de funciones que ha de realizar el servidor, si será Controlador de Dominio, qué dominio sirve, dónde estarán sus usuarios, etc. y definir sus recursos compartidos y los permisos de acceso a esos recursos.
[editar]
ejemplos de uso.-
/etc/init.d/samba
testparm -v
smbstatus
root@host# mount -t smbfs -o username=administrador //equipo/carpeta_origen /home/destino/
[editar]
estado de desarrollo
- los servidores con samba están en producción atendiendo eficazmente todas las peticiones que les realizan los dptos sin percances significativos hasta el momento; el resto de servidores samba están preparados para trabajar en cualquier momento en modo producción y configurados ya para trabajar con el servidor ldap en vez de mediante usuarios locales o de dominio;
- quedaría pendiente el cambio de discos físicos del servidor aaa debido a un problema en el particionamiento de su instalación que hace imposible acceder a las características de sus sistemas de archivos y quizá pueda ser la causa de un futuro fallo del sistema de archivos; ésta es la salida del comando df -h
Filesystem Size Used Avail Use% Mounted on /dev/hda1 -19135695371958k 1.0k 0.0k 97% /
- el siguiente paso en el desarrollo de esta tecnología debería llevarnos a la gestión total e integrada de usuarios windows mediante OpenLDAP y la protección de recursos compartidos mediante la gestión apropiada de esas contraseñas; técnicamente está todo preparado para abordar este cambio
