Gfarm is a distributed filesystem, generally used for large scale cluster computing. It's implemented in userland, and can be mounted by FUSE. It utilizes locality of a file to access a data node, and supports Globus GSI for Wide Area Network. Users can explicitly control file replica location on Gfarm. Gfarm can be used as an alternative storage system to HDFS for Hadoop, Samba, MPI-IO, and GridFTP. Monitoring via ZABBIX and Ganglia is also supported.
The stad (short for SMB Traffic Analyzer Daemon) program collects incoming data from the vfs_smb_traffic_analyzer VFS module included in Samba 3.2.0 and later. Of the received data, it builds an SQL store that can be queried. The SMB traffic analyzer software suite is a toolset aiming at visualizing the data flow on one or more Samba servers, providing statistics about the usage of Samba services. The long term goal of the SMB Traffic Analyzer project is to provide a universal remote debugging facility for Samba.
Pdbsql provides three samba passdb backend modules: pdb_mysql, pdb_pgsql, and pdb_multi. pdb_mysql is a MySQL passdb backend. pdb_pgsql is a PostgreSQL passdb backend. pdb_multi is a backend which loads multiple passdb backends. These are provided because support for MySQL and PostGreSQL passdb backends has been removed from the Samba source tree, due to lack of an active maintainer.
