Buenas!! Hace unos días formatee mi netbook y he vuelto a instalar el MSF, mi problema viene con el siguiente mensaje:

msf > db_driver

•         Available: postgresql, mysql

msf > db_connect base
[-] Error while running command db_connect: Failed to connect to the database: FATAL:  Ident authentication failed for user "root"
